Coldest Warmest Areas

Here are the coldest to the warmest areas of the state, based on 49 reporting stations.

Data, collected by month for thirty years, are calculated by recording the difference between the mean temperature for a month, and 65 degrees as the base temperature. (See detailed definition below.) HDD = heating degree days; CDD = cooling degree days; NET = the difference between HDD minus CDD; AP = Airport. See the monthly data.

Data from http://www.erh.noaa.gov/er/gyx/climo/ME_STATS_NEW.htm; calculation notes from http://www.erh.noaa.gov/er/gyx/climate_f6.shtml (accessed 12/15/2010)

Degree day is an index reflecting demand for energy to heat or cool houses and businesses. The “heating year” during which heating degree days are accumulated extends from July 1st to June 30th; the “cooling year” extends from January 1st to December 31st. A mean daily temperature (average of the daily maximum and minimum temperatures) of 65°F is the base for both heating and cooling degree day computations. Heating degree days are the differences between the mean daily temperature and the 65°F base; cooling degree days are the differences from the same base. For example, cooling degree days for a station with daily mean temperatures during a seven-day period of 67,65,70,74,78,65 and 68, are 2,0,5,9,13,0,and 3, for a total for the week of 32 cooling degree days.

The data, available in December 2010, are derived from 1971 through 2000. The thirty-year period is updated every ten years.

    We are considering a move to the state of Maine to spend our final days. We have heard that there is an area near (or on) the Atlantic coast that is generally much warmer than the rest of the state. Will you please be so kind to let us know if there is such a area and exactly where it is in the state? Many thanks.

      Based on the information in this article, Portland International Airport seems to give the City of Portland the edge. (Augusta, Lewiston, Sanford and Ellsworth are not coastal communities.)

      If you want to avoid the city, Brunswick fits your criteria the best. Port Clyde is a bit further down the coast. Belfast and Bar Harbor (Acadia National Park) are even further away and not quite as warm. [Search findbrunswick, or findportclyde, etc.]
