Climate Insight: Caribou Muni, ME
The NOAA 1991–2020 climate normals describe Caribou Muni, Maine as a location with an annual average temperature of 41°F, ranging from a mean daily high of 50°F to a mean daily low of 31°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00014607, 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. Caribou Muni receives roughly 40.7 inches of precipitation each year, with 118.2 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 7 and the first fall freeze near October 1. For energy use, 9,048 heating degree days and 225 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Caribou Muni scores 47/100 (Moderate), 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 July-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.
