Extensive work is in progress to transfer over 130 years of primary daily data observations including maximum and minimum temperature, precipitation, snowfall, snow cover, wind speed, sunshine and other parameters. This process will fill gaps and remove inconsistencies in the existing data base and begin the process of digitizing data that has never been tabulated […]
These figures summarize the daily temperature extremes, monthly precipitation, annual totals and other important weather events for the last few years. Annual Summary Graphs 2016 2015 2014 2013 2012
Weather observations on Blue Hill began on February 1, 1885, but the annual mean temperature plot below includes data for 1831 to 1884 from nearby locations that have been carefully adjusted to the Great Blue Hill summit, to extend the Observatory mean temperature record back to 1831. Long-Term Climate Graphs Annual Mean Temperature (since 1831) Annual […]
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 1891-2010 120-year, long-term average since 2012 and from the 1891-2000 110-year average for prior years. These long-term averages […]
