What August feels like
The serious stretch of hurricane season begins, and on an island that took the deadliest storm in American history nobody is casual about it — the seawall and the raised grade of the city exist because of 1900. In practice that means checking the tropics before you drive down, booking a rate you can cancel, and enjoying a hot, gloriously empty beach.
Expect about 5 days with real rain — enough to notice, not enough to plan around. Most afternoons push past 90°.
Can you swim?
The Gulf runs about 90° — bath-warm.
