At Logan Airport, where official records are kept, the average high temperature for 2012 was 61.5 [+2.7] and the average low was 46.9 [+2.9]. That resulted in an average temperature of 54.2, which is 2.8 degrees above the long-term average and is enough to beat out 2010 for the title of warmest year on record.
A total of 8 record highs were set during the year, most of which came in March and April as part of the warmest spring on record in Boston.
In addition to the warmth, the year was very dry. Precipitation only measured 36.73″, more than 7″ below average. Annual snowfall tallied only 12.1″, more than 31″ below average.
Records in Boston date back to 1872.
Elsewhere in Southern New England, early numbers show 2012 as the warmest on record in Worcester and Hartford as well. Providence will likely notch its second warmest year on record.
National weather data will be released over the next few weeks, but nation-wide 2012 is also likely to rank as the warmest year on record.
