Brunswick Maine climate
Brunswick has a substantial heating season and historical climate figures that need a current update
The reviewed historical normals show 45.23 inches of annual precipitation, 7,420 heating degree days, a July average maximum of 80.0°F, and a January average maximum of 31.0°F. These figures use 1961 to 1990, while NOAA identifies 1991 to 2020 as the current standard period. Use current station data when selected.
The practical climate choice still includes snow, freezing, rain, wind, storm tide, heating, insulation, roof, drainage, power, driveway, stairs, and winter transport. A home with good indoor cultural and social options can make the long season more manageable.
