What October feels like
Fantasy Fest closes out October and turns the town into something you should probably witness once. The heat starts stepping down late in the month while the water stays perfect for diving.
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.
Can you swim?
The ocean runs about 83° — bath-warm.
