What May feels like
Memorial Day weekend is the actual start of the season here — the beach patrol goes on duty, the piers open all day, and room rates roughly double overnight. Everything before that is quiet, pleasant, and one of the better-kept secrets on this coast.
Expect about 6 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy.
Can you swim?
The ocean runs about 58° — cold — a quick dip takes resolve.
