What May feels like
Spoleto Festival USA opens at the end of the month and the city runs on chamber music and late dinners for two weeks. The rain holds off better than you would guess for a Lowcountry summer month, but the humidity has already made up its mind.
Expect about 4 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 76° — comfortable for swimming.
