Frost Dates in New Jersey

Last and first frost at the 40 NOAA stations behind this site's New Jersey pages.

At the middle station of the 40 in New Jersey where a freeze comes every year, the last spring frost (50%) is April 16 and the first fall frost October 27, a freeze-free season of 193 days. The last frost is earliest at Atlantic City (Atlantic City, NJ, March 26) and latest at Bridgewater (Somerville 4 NW, NJ, April 30), 35 days apart. The season runs from 169 days at Medford to 243 at Pleasantville.

34 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 2 days earlier and the first fall frost 5 days later; the season lengthened at 30 stations and shortened at 3. 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.
