The yr with no summer time

The identify is hyperbole, after all. Meteorological summer time handiest began 3 weeks in the past, so it is nonetheless were given about 10 weeks to end up itself.

But it surely hasn’t began neatly 😢.

After a warmer-than-average wintry weather, colonies got here in the course of the wintry weather strongly, however issues then stalled and feature remained stalled for a number of weeks now.

A minimum of part my journeys to test at the bees during the last seven weeks have concerned opening hives within the rain. Some simply had me dodging intermittent mild showers, muddling thru after I didn’t dodge them, however in most cases getting what had to be carried out … er, carried out.

One, in early Might, concerned the unlucky accident of a near-Biblical deluge with my handiest alternative to test the colonies. I were given thru it, nevertheless it was once a dispiriting enjoy (for me and the bees).

Alternatively, ultimate weekend was once even worse.

I drove throughout to the apiaries underneath threatening skies, it began raining neatly prior to I arrived, and persisted in large part unabated till I after all deserted issues in disgust the next afternoon.

I spent part my time sheltering underneath bushes, within the automobile or in a lean-to shed with a ride-on lawnmower for corporate, and the rest squelching round getting extra pissed off as I were given ever-wetter.

I ended the second one day in a saturated beesuit, emptied the water out of my boots, modified out of my sodden garments and drove house in an overly dangerous temper.

I would accomplished about 20% of what I would deliberate to do.

Why investigate cross-check within the rain?

3 teams of beekeepers investigate cross-check their colonies within the rain:

1. the economic beefamers; with quite a bit of colonies, even with a 9, 10 or 14 day inspection cycle, they will have to be checked, come rain or shine. If an afternoon is neglected, then there shall be double that quantity to test the following day.
2. the deeply conscientious; if you recognize the invariable nature of the construction cycle of bees – specifically queens – then you’re going to bear in mind that some hive manipulations are time-critical. You can delay an inspection, however the emergence of queens is in large part unaffected by way of rainy or chilly climate. They will emerge on time … and most likely previous when you inadvertently grafted larvae that have been a bit of older than meant.
3. the terminally disorganised.

I have all the time been a member of the 3rd workforce, however attempt to be a member of the second one.

There is no likelihood I’m going to ever belong to the primary 😉.

My very own hive inspection agenda is constructed round a one-week cycle. This works neatly on the subject of swarm regulate and for the majority of hive manipulations together with such things as queen rearing.

Because of the far away location of maximum of my hives – one thing I’m hoping to quickly get to the bottom of – it additionally suits with affordable reasonable lodge reservations, pre-booked months upfront. Because the climate forecast can’t be trusted for the next day, I forget about it utterly when reserving ‘each and every Sunday evening from April to July’.

Beekeepers and fishermen

I have been each, so discuss from enjoy. Those two teams have a number of issues in not unusual:

• pros paintings onerous, frequently in physically-demanding stipulations (no less than, I be expecting they do … I am the very antithesis of ‘skilled’ as those pages frequently display), for rewards that don’t replicate the hassle expended {{1}}
• amateurs tend to magnify;
  • ‘you’ll have noticed the only I misplaced’,
  • ‘this large’ {{2}},
  • ‘twelve supers in keeping with hive’, and most likely ‘crammed in a single day’,
  • ‘averaged over 75 kg in keeping with colony’
• there is all the time one thing improper with the elements
  • ‘now not biting, too shiny’
  • ‘too rainy’ {{3}}
  • ‘no rain, the lime completely failed’
  • ‘early Autumn gales, they ate all of the heather honey’

And this yr, the issue has been each the chilly and the rain.

I’m the proud proprietor of 800 empty honey supers 😕

Get started as you imply to move on … then do not

Throughout the United Kingdom the wintry weather and spring temperatures have been a point (°C) or so hotter than the 30-year common. I mentioned this in mid April underneath the strapline “The whole thing is a little bit previous and so much wetter than ultimate yr.”

I am not in most cases keen on heat winters. I love the knowledge of a brood damage and the chance it supplies to truly hammer the Varroa inhabitants with a judiciously timed utility of oxalic acid.

Alternatively – despite the fact that heat(ish) – we would had a brood damage, I would slaughtered the vast majority of the rest mites, and the colonies truly took off as soon as the spring pollen and nectar become to be had.

I discovered the primary open queen cellular within the 3rd week of April, at the identical weekend as the primary supers have been added (each previous than any yr since 2015). The oil seed rape (OSR {{4}}) was once taking a look beautiful excellent, and there was once each and every reason why to wish for a bonanza spring crop.

Robust colonies and flowering OSR, coupled with climate that is heat and dry sufficient for foraging, can generate the ones “I am operating out of supers” issues that beekeepers whinge about (while secretly feeling smugly happy … it is a great drawback to have).

After which issues went a little bit pear-shaped.

Somewhat than inexorably emerging thru past due April, Might and early June, the temperature plateaued after which dropped. The ultimate week in Might was once exceptionally rainy, as was once the second one week in June. This diminished foraging considerably, slowing the speed at which the supers crammed.

But it surely had different results as neatly.

One truly glaring affect – glaring from knowledge accrued country-wide – was once the extend within the arrival dates of area martins and swifts. Those insectivorous birds stall their northwards migration if there are inadequate flying bugs. By means of the tip of Might, issues had stuck up, however the similar may now not be stated of the beekeeping season.

The yr with no summer time

The unique ‘yr with no summer time’ was once 1816. The eruption of Mount Tambora (now in Indonesia {{5}}) the former April introduced such a lot ash into the ambience that the common annual international temperatures have been diminished by way of 0.4-0.7°C.

That does not sound a lot, however the temperatures throughout the summer time rising season in Northern and Western Europe have been diminished by way of 2-3°C.

Plants failed, there was once well-liked famine and meals riots.

There have been knock-on societal results. Artists painted the wealthy pink hues of the fabulous sunsets (led to by way of the atmospheric particulates), the loss of oats to feed horses ended in the discovery of the velocipede, and Lord Byron, Mary and Percy Shelley and John Polidori escaped to the Villa Diodati in Switzerland to inform ghost tales.

Two of those, Frankenstein by way of Mary Shelley and – not directly – Byron’s brief tale The Vampyre (written by way of Polidori), at the moment are thought to be classics of literature.

I am not acutely aware of any data of the beekeeping in 1816, however I be expecting it was once a little bit of a shocker.

2024 isn’t like 1816. Even if temperatures – specifically for queen mating – had been depressed, there is nonetheless a cheap likelihood that there will be a summer time, and it could also be excellent for the bees.

Alternatively, the early summer time has been somewhat difficult, and it has created various issues for beekeepers.

The opposite distinction after all is that 1816 produced some literary masterpieces … I am positive that my miserably rainy visits to the apiary will lead to not anything of the type.

Supers

Supering early is helping scale back the force on house within the colony, and so contributes to swarm prevention. In a powerful nectar float, it additionally supplies ‘drying house’ for nectar with a top water content material.

If the nectar float continues, the gap within the comb is regularly crammed and the ripened honey is capped off to keep it. The perfect state of affairs is that the supers are utterly stuffed with capped honey because the nectar float after all dries up.

However attaining that takes a mixture of fine forage (so there is nectar to be had), excellent climate (in order that foraging is imaginable) and excellent judgement by way of the beekeeper (in now not including too many supers for the forage and prerequisites to be had).

Now we have now not truly had any of those this yr 😔.

This yr, the flying get started in past due April supposed that I overrated the supers wanted … by way of up to 100% in a few circumstances. I had colonies with 4 supers when two would have most likely been enough.

In truth, the outlet sentence of the ultimate paragraph isn’t somewhat correct; I estimated the selection of supers (primarily based upon colony power, and the prospective forage and most probably spring/early summer time climate) accurately, however the climate did not ‘play ball’ and foraging was once limited, that means I would equipped an excessive amount of house.

As a result, when clearing the supers, some have been packed, however others contained many wholly, or partly, empty frames.

I have but to extract (the supers are stacked within the heat to extend granulation) however be expecting the entire crop to be a bit of underneath common. No longer a crisis, however a lot lower than I would was hoping for.

Clearing supers with ripe honey

There are some things I believe when doing away with the honey supers:

• is the honey ‘ripe’, with a low sufficient water content material (lower than 20%) that it’s going to now not ferment in garage? {{6}}. I have handled this subject – and the informative ‘shake check’ – rather not too long ago, so would possibly not repeat myself right here.
• is there enough honey within the tremendous to make it value extracting? It is simple to steadiness complete frames, however much less so if they are partly empty.
• if I take all of the honey, may the colonies starve if there is a pronounced ‘June hole’?
• if I empty the supers will the brood field be left so filled with bees, that swarming could be precipitated?

All of those – apart from for the primary merchandise within the record – contain a mixture of enjoy, excellent judgement and ‘guesstimates’.

Fairly a little bit of the latter if I am fair.

Even if I hardly ever glance within the supers throughout inspections {{7}} I do attempt to pass judgement on their weight. Because the honey is ripened, I attempt to transfer the heaviest supers to the highest of the stack.

If a perfect incorporates a few crammed and capped frames, with the remainder in large part empty, I’m going to shuffle frames within the stack of supers to transport the entire ones in opposition to the highest.

That is all very inexact and a bit of bit arbitrary … nevertheless it does make the following bit more straightforward.

I upload the clearer above the tremendous I believe is:

• now not value extracting, or
• complete or partly filled with unripe honey, or
• wanted by way of the bees if it rains for a fortnight

Until, by way of exceptionally excellent judgement a miracle, I have were given a stack of utterly crammed supers, this generally manner I go away one (or this yr two, in some circumstances) supers on each and every hive.

Casting off supers in heavy rain

I have carried out a large number of this within the ultimate fortnight.

There are two issues right here … the primary is that all the bees are ‘at house’ as it is too rainy to forage. The second one is {that a} heck of a large number of bees are cleared out of the supers, and maximum of them congregate inside the house created by way of the deep decrease rim of the clearer design I exploit.

Those clearers paintings exceptionally neatly.

I put some on at 10 am in the future ultimate week and estimated that neatly over 80% of the bees had moved down after I checked once more at 4 pm at the identical day. Used in a single day there are hardly ever greater than a dozen or two stragglers, despite the fact that the tremendous incorporates unripe nectar {{8}}.

On a dry day I simply take away the supers, gently carry the clearer and provides it a pointy shake or two excessive of the open hive. Inevitably, some bees pass over the objective and finally end up at the floor, or the hive stand.

That isn’t an issue on a heat, sunny afternoon, however probably deadly in a downpour {{9}}.

To steer clear of this I have discovered that delicately – and temporarily – lifting one aspect of the clearer by way of a part centimetre or so, then sharply banging it down onto the hive (most likely then repeating it at the reverse aspect of the clearer) clears maximum of the bees, with out masking the bottom, the stand, my boots and the adjoining hives with clumps of disoriented bees.

Do that temporarily sufficient and you do not weigh down bees between the hive rim and the clearer both.

I generally give them a gasp or two of smoke in the course of the clearer ‘exits’ first as neatly.

If you wish to investigate cross-check the colony, accomplish that prior to including the clearer. As soon as the supers are empty, the brood field shall be full of bees, and it’s going to be a lot more tough to look issues. This additionally implies that the inevitable disruption led to by way of bashing the clearer down is not going to agitate the bees prior to you investigate cross-check them.

Queens

Suffice to mention, the mix of depressed temperatures and double the typical rainfall during the last 7 weeks has had somewhat an affect on swarming and queen mating.

By means of ‘somewhat an affect’ I imply there is been nearly none of both.

Within the graph above, the 2024 knowledge are plotted in forged strains, with the typical of the previous 5 years in dashed strains. I have plotted the imply temperature (°C) in blue, the utmost day-to-day temperature (°C; each at the left-hand axis) in pink and the cumulative rainfall (mm; at the right-hand axis) in black.

Massive portions of Might and June had been rather dry this yr, but if it is been rainy, it is been very rainy. And when it hasn’t been rainy, it is been cool.

My ‘again of an envelope’ calculations – taking account of the imply and the utmost day-to-day temperature, the day-to-day rainfall (and when the latter two happen) counsel that – on common – a normal yr may have ~24-28 days throughout the length graphed by which queen mating may happen.

This yr, that quantity is most likely not more than 10 days, and most likely as few as 5 – 6 (the unshaded spaces within the graph above).

I’m going to speak about those calculations one day someday, as I do not recently know whether or not some (or any 😢) of my queens are effectively mated.

So, from a beekeeping standpoint, what did I see within the hives?

(Virtually) no swarming

I have misplaced no swarms in keeping with se, however I did lose one or two clipped queens in past due April or very early in Might when colonies tried to swarm.

Generally since then, when engaging in an inspection, I would discover a laying clipped queen and one or a number of sealed queen cells. It wasn’t strange to seek out an emerged virgin queen and a laying clipped queen in the similar field.

Lots of the sealed queen cells contained mature virgin queens. If I gently uncapped the cellular, the virgin queen (VQ) would come scuttling out.

I have misplaced rely of the selection of hives I may listen a piping queen in. That is the function sound made by way of a virgin queen.

With dire climate forecasts for the fortnight or extra after the inspection, I’d generally unencumber the VQ and let the colony fix things out. In higher climate, I would have carried out some kind of swarm regulate {{10}}. Alternatively, there appeared little level in splitting a manufacturing colony with nearly no likelihood the VQ would get mated inside the foreseeable long term.

Whether or not this was once the best technique will want the advantage of hindsight … in lots of packing containers the VQ it appears disappeared, in others each queens remained provide.

Queen mating

My ‘again of the envelope’ calculations are crudely primarily based upon temperature and rainfall stats from an lovers native climate station.

We all know so much about queen mating flights; 80% happen between 1 pm and four pm, they common ~18 mins period and the queen takes ~5 over a length of 1-5 days … do the math!

The evidence of the pudding is that I am handiest acutely aware of one queen getting effectively mated within the ultimate 6 weeks or so.

It’s been dire.

Time after time, I would open the field to seek out ‘polished cells’ within the centre of what must be the brood nest, and both no signal of a queen, or a virgin scampering round getting hassled by way of the employees.

This ‘one in six weeks’ quantity is also improper; I deserted maximum hive inspections ultimate weekend because of the deplorable climate. Most likely all of them were given mated in mid-June, when the temperature in short (for simply 90 mins at the 15^th!) exceeded 20°C.

A in a similar way transient length of heat climate took place at the 19^th.

Queen rearing

Ha! Do not make me chuckle.

I have raised a large number of queens, however it is been a futile workout.

Alternatively, now not all is misplaced. I have discovered so much about caging queen cells early, temperatures they are able to face up to (12-15°C for hours), and the impact of humidity on VQ’s allowed to emerge within the incubator.

I simply do not know whether or not the queens have due to this fact been effectively mated … however hope to quickly to find out.

And, if they are now not, there is nonetheless time to rear a pair extra batches … and pray for higher climate.

Most sensible(ical) tip

Sponsors of The Apiarist get a ‘Most sensible Tip’ of their Bees within the Information per thirty days publication. Alternatively, the following of those is a fortnight or so away, and this tip is each time-sensitive and one I have given a couple of years in the past.

UK readers is also conscious that there is an election at the 4th of July.

There are 650 seats and a file overall of four,515 applicants. Of those, 3,685 shall be upset and – if the polls are correct {{11}} – loads shall be from the most important 3-4 events, all of which produce numerous promoting.

And a few of this promoting is on weatherproof revealed Correx indicators. Correx has a lot of makes use of in beekeeping – from touchdown forums to roofs.

It is magic stuff.

Many unsuccessful applicants are not likely to face once more, so the broadcast Correx promoting shall be discarded or recycled. Glance out for piles of blue or yellow or (much less most probably) pink Correx sheets close to your native constituency administrative center (or ditches in constituencies with specifically deficient losers).

In fact, now not all of this Correx shall be helpful. The O’Hara signal above would possibly not make anything else a lot larger than a Varroa tray. Alternatively, if the unsuccessful candidate is known as Christopher Cholmondeley-Pennell you may be able to construct a top-bar hive – or, with a few forums, a bee shed – from Correx.

Christopher Cholmondeley-Pennel has 31 characters in his identify. The informative democracyclub.org.united kingdom lists 18 applicants with names containing 31 or extra characters, and an additional 99 with no less than 25 characters.

Now, if that’s not a peak tip, I do not know what’s 😉.

This put up was once printed at the 21^st of June, the summer time solstice, and likewise the beginning of astronomical summer time. Most likely the entirety will support to any extent further?
