Frost Dates Updated for 2026

The Old Farmer's Almanac uses a formula that takes into account both climatological normals and historical weather data to make its frost predictions. These dates are predictions, not guarantees, and local microclimates can vary significantly. Gardeners should always monitor local weather conditions and adjust their planting schedules accordingly. Knowing the average last frost date helps gardeners avoid the disappointment of losing young plants to a late cold snap. It's a crucial piece of information for successful spring planting.
