What August feels like
The rain picks up in August and arrives in short heavy bursts rather than gray all-day drizzle, so you lose an hour, not an afternoon. Crowds start easing after the second week as school districts back home restart.
Rain arrives about 8 days of the month, so keep one flexible day in your plans. about 6 afternoons top 90°.
Can you swim?
The ocean runs about 84° — bath-warm.
