What July feels like
The old houses were built with those long side piazzas facing southwest for a reason: they were catching a breeze that mostly shows up after dark. Sullivan's Island and Folly fill every weekend, so go on a Tuesday if you can choose.
Rain arrives about 8 days of the month, so keep one flexible day in your plans. about 9 afternoons top 90°.
Can you swim?
The ocean runs about 86° — bath-warm.
