Charts of Monthly Blue Hill Observatory Climate Data

The charts below show annual and monthly average temperature and total precipitation and snowfall as well as their departures from average since 1995. Note that departures from the mean depicted in these plots are differences from the 1891-2020 130-year, long-term average since 2021, from the 1891-2010 120-year average for 2012-2020, and from the 1891-2000 110-year average for prior years.  These long-term averages are much less variable than recent 30-year “normals”.
