What October feels like
October is Ironman month, and the race has been part of this town's identity since the seventies — race week closes roads and fills every room a year ahead. Outside that week, it's one of the better-value stretches on the island.
Real rain shows up about 2 days all month; the rest stay dry.
Can you swim?
The ocean runs about 81° — bath-warm.
