If you have the choice in being there... better go in may... (IMO)
Summer... Mostly HOT and very humid... sometimes in the high 90s last august there were days of 98F.. in the afternoon rain... sometimes just a small shower but very often POORING RAIN...
How we're dealing with it??? Water... drinking LOTS of water...
Use plenty of sunscreen, always wearing a cap...
And when I'm home I stay inside, or at least out of the sun...
So the nights are my favorite...
Hot! Humid! Rainy! I would much rather go over spring break than in the summer. We bought a mister fan that helped while waiting in lines that were outside.
