What October feels like
October is the turn: the first proper rain bands come through and North Shore swells start stacking up for winter. Rates stay low right up until the holidays, and the marathon crowd begins showing up along the Ala Wai at dawn to train.
Real rain shows up about 3 days all month; the rest stay dry. It’s sticky — light fabrics and an afternoon break earn their keep.
Can you swim?
The ocean runs about 81° — bath-warm.
