What May feels like
May is a genuine local favorite: the summer crowds haven't landed, the north shore has gone flat and snorkelable, and Tunnels is back to being one of the best reefs on the island. Rain is still around, but it's the passing kind that dries off you.
Expect about 4 days with real rain — enough to notice, not enough to plan around. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 81° — bath-warm.
