The 2026 Frost-Freeze program for the Maine foothills, White Mountains of NH, Connecticut River Valley in NH, Monadnock region of NH, Lakes Region of NH, and the Merrimack River Valley in NH has ended. This means that Frost or Freeze headlines will no longer be issued for this region for the 2026 season. If you still have sensitive plants outdoors, it is recommended to follow local forecasts and take preventative actions from a frost or freeze when temperatures are forecasted to be in the mid to upper 30s or colder. The Frost-Freeze program of the National Weather Service is to warn local growers and gardeners of the potential of a damaging frost or freeze for a given area during the climatologically defined growing season. This allows people to take preventative measures for plants and crops against potential damaging temperatures. The climatologically defined growing season is the period between the median date of the last Spring freeze and the first Fall freeze. These are the dates in which NWS frost advisories or freeze warnings would no longer be issued for the 2026 growing season in NH and Western ME. September 21: COOS County NH and the Western Maine Mountains. October 1: Maine Foothills, Interior York, White Mountains of NH, Connecticut River Valley in NH, Monadnock Region of NH, Lakes Region of NH, and the Merrimack River Valley in NH. October 11: Seacoast of NH, Coastal York, Cumberland, Androscoggin & Kennebec counties in Maine, plus the Midcoast of Maine. Please visit www.weather.gov/gyx for the latest forecasts. $$
