During what condition do bees utilize water for hive cooling?

Bees utilize water for hive cooling primarily during the summer. During this season, temperatures can become quite high, which may lead to overheating within the hive. The bees collect water and then use it to regulate the hive's temperature through a process known as evaporative cooling. They spread the water on the surfaces of the hive and fan their wings to promote evaporation, which helps lower the internal temperature. This behavior is crucial for maintaining a conducive environment for the brood and the overall health of the colony.

In contrast, during the winter, bees cluster together to keep warm, while in spring and fall, they are actively involved in foraging, building up their stores for the winter, or preparing for changes in weather, but are not primarily focused on cooling the hive.
