Honolulu — local weather overview
Honolulu is on the south shore of Oahu in Hawaii, facing the Pacific Ocean between the harbor, Waikiki and the volcanic Koolau Range. A 24 hour forecast is useful here because sea breezes, strong sun, brief tropical showers, surf conditions and weather differences between the coast, hills and valleys can change plans quickly.
Honolulu is often classified as having a tropical savanna climate in the Koppen system (As), while some sources describe it as hot semi arid (BSh) because of the rain shadow. Temperatures vary little through the year: summer daytime values are usually around 29-31°C (84-88°F), while winter is often about 26-28°C (79-82°F). The wetter season is mainly October to April, summer is drier, and UV levels stay high much of the year.
Before walking around Waikiki, hiking Leahi Diamond Head, visiting Pearl Harbor, Iolani Palace, Ala Moana, Hanauma Bay or the waterfront, check temperature, wind, showers, UV and cloud cover. The hourly forecast helps choose better times for beaches, surfing, viewpoints and evening routes.
