What July feels like
July runs the island at capacity — the bike rentals sell out, the Salty Dog has a line, and the beach lots fill before nine. The ocean is warm enough that it stops being refreshing, so shade and a pool become the afternoon answer.
Rain arrives about 8 days of the month, so keep one flexible day in your plans. Full tropical humidity: mornings are your friend, and shade is currency. Most afternoons push past 90°.
Can you swim?
The ocean runs about 85° — bath-warm.
