What April feels like
The Cooper River Bridge Run takes the first Saturday and the whole Lowcountry seems to jog into downtown from Mount Pleasant. After that it is the sweet spot — azaleas still going, air conditioning still off, shrimp and grits eaten outside without regret.
Expect about 5 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The ocean runs about 68° — brisk but swimmable.
