🌡️ Summer Heat Stress: A Practical Mitigation Checklist for Hives
Recognising the temperature thresholds that harm brood and adult bees, and the shade, ventilation and water measures that keep hives cool through a UK heatwave.
A cutaway beehive shows how outside temperature, ventilation, fanning bees, shade and water combine to set the brood-nest temperature during a heatwave — and what happens to the comb when it runs too hot.
🔬 What It Demonstrates
Brood needs roughly 35°C. Passive ventilation, active fanning, shade and evaporative cooling from water each pull the internal temperature down; the comb frames tint from amber to red and visibly sag once the wax-softening threshold is crossed.
🎮 How to Use
Raise the outside temperature to simulate a heatwave, then use ventilation, fanning, shade and water to bring the brood-nest temperature back into the safe range. Watch the coloured airflow particles speed up and vent through the roof.
💡 Did You Know?
On extreme days beekeepers may see "bearding" — a curtain of bees clustering outside the entrance simply to get their own bodies out of an overheated box and reduce internal crowding.
