Hot weekend for the bees

The bees are doing well this weekend but it was very hot and humid. For most of the afternoon, they were seen covering the fronts of the hives. #s 3, 4 and 7 had some interesting activity. Many bees were facing down, either scraping or rubbing the surface of the hives. We think they might have been trying to get dry after a shower, trying to stay cool, or trying to get moisture off the hive.
