The information in the tables below represent the average dates on which the prescribed temperatures occured - the climatological average first or last frost and freeze dates. Many variables dictate the actual first frost or freeze, including cloud cover, wind speed, soil moisture and location of the temperature sensor. Some temperature reporting sites are located in town while some are more rural. Sites in town tend to experience frosts and freezes a little later in the year, while rural sites tend to see frosts and have freezing temperatures a bit earlier. Based on 1981 - 2010 data.

NOAA's 1981-2010 Climate Normals
NOAA's National Climatic Data Center (NCDC) released the 1981-2010 Normals on July 1, 2011. Climate Normals are the latest three-decade averages of climatological variables, including temperature and precipitation. This new product replaces the 1971-2000 Normals product.  Additional Normals products; such as frost/freeze dates, growing degree days, population-weighting heating and cooling degree days, and climate division and gridded normals; will be provided in a supplemental release at a later date.
