What August feels like
August is when the trades occasionally step aside for a passing system out of the eastern Pacific — usually nothing, occasionally a stretch of heavy, still air locals grumble about. The east end past Hana stays green all month while the isthmus browns off; same island, an hour apart.
Real rain shows up maybe one day all month; the rest stay dry. It’s sticky — light fabrics and an afternoon break earn their keep. about 9 afternoons top 90°.
Can you swim?
The ocean runs about 80° — bath-warm.
