Honolulu, Hawaii Weather in March

March weather

March feels warm and humid, with highs around 25°C and nights near 22°C. Rain falls on 15 days, but showers often leave time for outdoor plans. You can explore ʻIolani Palace, stroll Waikiki, or spend a sunny spell at Ala Moana Beach.

The wet spells can make Manoa Falls Trail muddy, and cloud can soften the views from Diamond Head. Keep a flexible plan for hikes, and swap in the Bishop Museum if rain settles in. March is wetter than April, so don't expect every beach day to be clear.

Festivals and local days

The Honolulu Festival brings cultural performances and a grand parade through Waikiki, usually in March. Prince Kūhiō Day, on March 26, honours the Hawaiian royal who served as a territorial delegate. You may see local events around the holiday.

For families, the festival's dance performances offer an easy way to add local culture between beach time and Waikiki walks.

Crowds and practical tips

March sits between winter's busy holiday season and the summer rush. It can feel calmer than those peak periods, though school spring breaks bring more visitors and can lift hotel rates. It's not a reliably cheap month, especially around popular travel weeks.

If you're heading to Manoa Falls, check the trail after heavy rain; the path can turn slick. Around Waikiki Festival weekend, allow extra time for the parade and street closures. Honolulu's weather can shift quickly, so keep a museum or a meal of poke in reserve for a rainy afternoon.
