Climate Change and the Honeybee: What the Future Holds
This summer's heatwaves weren't just uncomfortable for us. For honeybees across the UK, they were a warning sign.
As temperatures continue to break records and seasonal patterns grow increasingly unpredictable, beekeepers are watching their hives with a new kind of concern. The relationship between bees and their environment is finely tuned, and climate change is starting to throw that balance off.
Here's what we know, what we're watching, and why it matters far beyond your breakfast table.
How Heatwaves Stress Honeybee Colonies
Bees are remarkably adaptable, but they're built for a particular climate range. When temperatures soar -as they did repeatedly across the UK this year - colonies face a cascade of challenges.
Inside the hive, bees work constantly to maintain a core temperature of around 35°C for the brood. During extreme heat, this becomes a full-time emergency. Worker bees abandon foraging duties to fan the hive and collect water for cooling. Foraging stops. Honey production slows. In the most severe cases, wax combs can soften and collapse under the heat.
Outside the hive, prolonged dry heat causes flowering plants to shut down nectar production prematurely. A hot, dry June might look beautiful — but for bees, it can mean a near-total loss of forage at a critical time of year.
Will Bee Behaviour Change?
Almost certainly, and in some ways it already is.
Beekeepers across the UK are reporting shifts in swarming patterns, with some colonies swarming earlier and more frequently as the climate warms. Bees are also beginning to forage earlier in the day to avoid peak afternoon heat - a small but telling behavioural adaptation.
Longer, milder autumns can confuse colonies into staying active too late in the season, burning through winter stores before the cold truly sets in. Conversely, mild winters can allow colonies to grow too large too soon, only to be caught out by a late frost.
The bees are adapting - but the pace of change is the concern. Evolution is slow. Climate change is not.
How Will the Forage Change?
This is perhaps the most complex piece of the puzzle. Warming temperatures are already shifting the flowering times of many plants. Some are blooming weeks earlier than they did a generation ago. Others are being outcompeted by invasive species that thrive in warmer conditions.
For bees, timing is everything. If a key forage plant, say, white clover or field beans, flowers two weeks earlier than the colony is ready to exploit it, that nectar flow is lost. Mismatches between bee colony cycles and plant flowering times are one of the most serious emerging threats to pollinator health.
On the other hand, some plants that were previously marginal in the UK are extending their range northward. New forage sources are appearing. The composition of what's available, and when, is quietly shifting, season by season.
For honey, this means flavour profiles will change over time. The quintessentially British summer honey of today may taste quite different in twenty years.
Will Bees Survive?
Honeybees are resilient, but they are not invincible - and they don't face climate change in isolation. It compounds other existing pressures: Varroa mite infestations, habitat loss, pesticide exposure, and disease. A colony already under stress from Varroa is far less able to cope with a brutal heatwave or a failed forage season.
The picture isn't uniformly bleak. Some research suggests that warmer springs could extend the foraging season overall, benefiting colonies in certain regions. Beekeepers are already experimenting with more heat-tolerant strains of bees and adapting hive designs for better ventilation.
But the honest answer is: the bees that survive will be those with beekeepers who are paying close attention, adapting their practices, and managing their colonies with the kind of care that climate instability demands.
How Will Beekeeping Practice Need to Change?
The beekeeping of the next generation will look meaningfully different from that of the last. Some of the shifts already underway include:
- Water provisioning — providing hives with reliable water sources during heatwaves, something many beekeepers now treat as essential rather than optional
- Hive placement and shading — repositioning hives out of direct afternoon sun, using shade cloth, and choosing north-facing aspects in hotter climates
- Adapted inspection schedules — working hives earlier in the morning to avoid peak heat stress
- Supplemental feeding — being more proactive with emergency feeding during forage gaps caused by drought
- Genetic selection — greater interest in adapted bee strains with natural resilience to the emerging conditions of British summers
At Haskins Honey, we're already thinking about all of this. Our bees, our practices, and our colony management are evolving alongside the seasons.
The Wider Picture: Bees and Local Ecology
Here's why this matters beyond honey. Bees pollinate approximately a third of the food we eat and a much larger proportion of wild plant species. When bee populations are disrupted - whether by climate stress, disease, or habitat loss - the effects ripple outward through entire ecosystems.
Fewer bees mean less pollination. Less pollination means fewer fruits, seeds, and berries - not just for us, but for the birds, mammals, and insects that depend on them. A decline in bee health is rarely just a beekeeper's problem. It's an ecological problem, working its way quietly through the food web.
Healthy bee populations are a marker of a healthy landscape. Which is why, as beekeepers, we consider ourselves as much land stewards as honey producers.
What You Can Do
The good news is that gardens, window boxes, and balconies genuinely matter.
Planting bee-friendly flowers, including lavender, borage, foxglove and wild marjoram, gives bees the diverse, reliable forage they need.
Avoiding pesticides, leaving a patch of lawn unmown, and putting out a shallow dish of water during hot spells all make a real difference.
Supporting local, traceable beekeepers is also a meaningful choice. Every jar of Haskins Honey represents hives that are actively managed, monitored, and cared for through the seasons. We can see first-hand how changing weather and flowering patterns affect our bees, and the honey they produce.
