What to pack

What August feels like

August is the busiest stretch of the central Pacific hurricane season. Most storms fizzle or slide well south, but the ones that pass near shut the trade winds off and leave the air standing still and muggy for a few days; locals check the wind before they check anything else.

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 10 afternoons top 90°.

Can you swim?

The ocean runs about 81° — bath-warm.
