A little known tidbit, the more humid it is the cooler an esc and motor will run. Brought to you by Bill Nye the Science Guy.

Yea the reason high humidity makes humans feel hotter is that we can't evaporate any sweat off our skin which is what cools us.
Water absorbs heat better than air, which is why water cooling is better than air cooling.
