Yesterday (sunny and HOT day) while in the pool with my daughter my bees decided to join us, like 50 of them. Honey bees kept falling in the pool and could not take back off. We had to use the skimmer to lift them up and then they flew away. Were they that thirsty? They would of all died if we did not lift them up.. Was interesting, they just kept "jumping" in the pool.. About 5pm they stopped.
1st year with bee so I am not sure if this is something I should expect.
