What August feels like
August is the last of the summer crowds, and the reefs at Tunnels and Kee are at their gentlest. It's also the busy stretch of central Pacific hurricane season, which mostly means a week or two of keeping half an eye on the forecast.
Expect about 5 days with real rain — enough to notice, not enough to plan around. Full tropical humidity: mornings are your friend, and shade is currency.
Can you swim?
The ocean runs about 84° — bath-warm.
