Old Farmer's Almanac Frost Map

The Old Farmer's Almanac's map provides dates for the final spring frost, which helps gardeners know when to plant without risking damage from freezing temperatures. These dates are predictions based on historical weather data and are not guarantees. The Almanac divides the US into zones, each with its own estimated last frost date. For example, the southern regions might have a last frost date in February, while northern areas could be as late as June. Knowing your local frost date allows you to start seeds indoors ahead of time, giving plants a head start. You can also use the information to decide when it's safe to transplant seedlings outdoors.
