Typical weather, averaged over 30 years (1995–2024), read 6 km east of Honolulu. Its own grid square is mostly sea and holds only a daily average, so the page reads the nearest square with a true high and low near the town's height. Temperatures are adjusted against 66 weather stations: daytime highs read about 3.1°F cold in the source data and are raised to match, and both highs and lows are adjusted for the town's height (0 m) against the climate model's (86 m).Temperatures are adjusted against 66 weather stations: daytime highs read about 1.7°C cold in the source data and are raised to match, and both highs and lows are adjusted for the town's height (0 m) against the climate model's (86 m).
