What August feels like
August is when this coast starts paying real attention to the forecast, without letting it wreck the week. The offshore fishing tournament fills the marina early in the month, and the Gulf is warm enough that getting in offers no relief at all.
Expect about 4 days with real rain — enough to notice, not enough to plan around. Full tropical humidity: mornings are your friend, and shade is currency. Most afternoons push past 90°.
Can you swim?
The Gulf runs about 84° — bath-warm.
