Frost Dates in Massachusetts

Last and first frost at the 66 NOAA stations behind this site's Massachusetts pages.

At the middle station of the 66 in Massachusetts where a freeze comes every year, the last spring frost (50%) is April 27 and the first fall frost October 15, a freeze-free season of 169 days. The last frost is earliest at Malden (Boston Logan International Airport, MA, April 4) and latest at Huntington (Worthington, MA, May 13), 39 days apart. The season runs from 141 days at Rutland to 218 at Malden.

50 of these stations were also in NOAA's previous normals, for 1981–2010. Between the two, the median station's freeze-free season grew 7 days longer, with the last spring frost 3 days earlier and the first fall frost 4 days later; the season lengthened at 41 stations and shortened at 7. The two periods share twenty years, so the change reflects mostly 2011–2020 against 1981–1990.

50% dates from NOAA NCEI U.S. Climate Normals 1991–2020, one row per station; a state page is published when at least 5 stations stand behind its pages. Where a freeze comes in fewer than nine winters in ten, the dates describe the winters that have one.
