First Frost Dates for 2026: Regional Overview and Gardening Tips
The Farmers' Almanac has released its 2026 guide to first frost dates across the United States, providing a regional breakdown of when gardeners and farmers can expect the first frost of the season. Frost dates vary significantly depending on location, with northern and high-elevation areas like Alaska and the Rockies seeing frost as early as late August, while southern regions such as the Gulf Coast may not experience frost until late November or December. Frost occurs when ice crystals form on surfaces, often under clear, calm conditions, even when air temperatures are slightly above freezing. The guide also explains the difference between frost and freeze, with freezes defined as air temperatures dropping to 32°F (0°C) or lower. These dates are based on historical climate data from NOAA and the Farmers' Almanac, offering a valuable resource for planning gardening and agricultural activities.
