What August feels like
August is the busiest stretch of the central Pacific hurricane season, and the east side is where a storm would arrive first — most years they slide south and all you get is swell and thick air. People here keep water in the garage and get on with it.
This is the wet season: rain on about 18 days, so pack accordingly. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 80° — bath-warm.
