Honolulu, Hawaii Weather in December

December weather

Honolulu stays warm in December, with daytime highs around 25°C and nights near 23°C. The air feels humid, and rain falls on about half the days, often in passing showers. Waikiki Beach and the shops along Kalākaua Avenue still work well between showers, but keep flexible plans for outdoor stops.

Rain can leave the Manoa Falls Trail slick and muddy, so skip it when the path is wet. For a drier day, visit ʻIolani Palace or the Bishop Museum instead.

Holidays and events

Honolulu City Lights brings holiday displays to Honolulu Hale, the city hall downtown. The Honolulu Marathon also draws runners and spectators, while Pearl Harbor remembrance events mark December 7. Christmas and New Year bring a festive feel, especially around Waikiki.

Families who enjoy holiday lights may like an evening at Honolulu City Lights, but expect more people around the displays.

Crowds and local tips

December is one of Honolulu's busiest and pricier months, especially around Christmas and New Year. It's a sharper contrast with quieter periods, and January is also among the best months overall for a visit. If you prefer calmer beaches and lower prices, December may not suit you.

For a practical rainy-day swap, take TheBus to Chinatown for lunch and explore its shops and historic streets. If you're heading to Manoa Falls, check the trail after rain; muddy footing can turn a short hike into a slippery one.
