Honolulu in October

The wet season creeps in but rain is still modest, making this a pleasant travel month. It remains warm. Autumn holiday weeks in East Asia, which follow the lunar calendar, can add to the crowds.

Highs averaged 31°C and lows stayed at 23°C, so the heat hung on long after sunset. Out of 31 days, about 5 brought rain; the rest stayed dry. A visitor in 2009 met 1 rain day; one in 2014 met 9. The average of 5 hid that gap.

22 days past 30°C made it a month for early starts and a long lunch indoors.
