These thirty-year averages, computed from station USW00022519, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Kaneohe Bay Mcas receives roughly 27.8 inches of precipitation each year, with seasonal snowfall possible. Growing-season length varies with elevation and microclimate, with the last spring freeze near N/A and the first fall freeze near N/A. For energy use, 0 heating degree days and 4,245 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Kaneohe Bay Mcas scores 82/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for September-driven heat, or deep winter for February-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
