Ever wonder what bees do when it is in the 90s? Thousands of workers busy building comb, making honey, feeding the babies, feeding the Queen (she never feeds herself). This plus a hive box in the sun most of the day with very little ventilation must get very very hot.
They sit on the veranda and fan themselves. This is called "bearding" in the bee keeper world, for obvious reasons.
They also send out the foragers to get water for all the workers.
