Honolulu in March

Both our data and airport records put this among the rainiest months. A winter low known as a Kona storm can bring several gray, wet days in a row. US spring breaks begin toward the end of the month, bringing more families.

Highs averaged 28°C and lows fell only to 20°C, so evenings brought some relief. 7 rain days in a typical March: noticeable, but most days stayed dry. A visitor in 2015 met 1 rain day; one in 2006 met 21. The average of 7 hid that gap.

Highs passed 30°C on 1 day on average.

Hurricanes i No tropical storm passed within 300 km in this month over the last 20 years. Hurricanes: July to October
