What March feels like
The island fills for spring break and Seawall Boulevard traffic becomes a fact of daily life. The Gulf is warming but hasn't arrived — most people are on the sand rather than in the surf, and the wind this month is relentless.
Expect about 4 days with real rain — enough to notice, not enough to plan around.
Can you swim?
The Gulf runs about 66° — brisk but swimmable.
