Climate Insight: Molokai, HI

The NOAA 1991–2020 climate normals describe Molokai, Hawaii as a location with an annual average temperature of 76°F, ranging from a mean daily high of 83°F to a mean daily low of 69°F. August is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00022534, 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. Molokai receives roughly 21.7 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 3,981 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Molokai 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 August-driven heat, or deep winter for January-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.
