Although most changes are measured in days rather than weeks, the publication says even small timing differences can affect early planting decisions. The map is intended to help growers avoid frost damage while taking advantage of favorable conditions where the season may begin slightly sooner.
The color-coded guide divides the country into three categories: areas where the final frost may arrive earlier than usual, places where it is expected to occur near the historical average, and regions where the season may end a little later. According to The Old Farmer’s Almanac, these variations typically range between one and two weeks.
Earlier Frost Endings Expected Across Several Eastern and Central Regions
Large portions of the eastern United States are predicted to see the final frost arrive earlier than average in 2026. According to The Old Farmer’s Almanac, green shading on the map, indicating an earlier frost end, covers Boston and much of New England, suggesting that gardeners there may be able to begin planting slightly sooner than usual.
Similar patterns appear along the Atlantic corridor. Parts of New Jersey, New York City, and Philadelphia are also shaded green, reflecting a projected shift toward an earlier end to frost conditions in those urban and surrounding areas.
The trend extends further south. According to the Almanac’s regional breakdown, the Carolinas and eastern Georgia show the same early-season signal, potentially lengthening the window for spring planting in parts of the southeastern United States.
In the central states, Kentucky and much of Indiana are likewise marked in green. Portions of Missouri and Kansas also fall into the earlier-than-average category, while northern Oklahoma near Oklahoma City is included in the same band.
These projections remain relatively modest in scale. The Old Farmer’s Almanac explains that most of the differences are limited to about one or two weeks, though even a few days can influence when frost-tolerant vegetables and flowers are planted.
Later Forecast in Parts of the West and Florida
While several regions may see an earlier start to spring planting, the map indicates that other areas could experience a later end to frost conditions. According to The Old Farmer’s Almanac, blue shading marks locations where the final frost may arrive roughly one to two weeks later than the long-term average.
Central Florida, particularly around Orlando, falls into this category. Northern and southern parts of the state are expected to remain close to normal timing, shown in yellow on the map.
In the western United States, later frost dates appear across a broad swathe of the Intermountain region. Idaho, eastern Oregon and Washington, as well as northern Utah and Nevada, are marked in blue, suggesting a delayed transition to frost-free conditions.
Northern Montana is also highlighted for later frost potential, while much of the surrounding Mountain West remains near the seasonal average. Meanwhile, areas across the Upper Midwest show mostly normal timing, with some northern edges trending slightly later.
According to Sarah Perreault, managing editor of The Old Farmer’s Almanac, the broader seasonal outlook also points to warmer-than-normal conditions across much of the United States during spring 2026. She previously told Newsweek that parts of Washington, Oregon, Idaho, Montana, and Colorado may experience temperatures closer to or below seasonal averages.
The Almanac notes that its frost map is designed to guide the earliest plantings of the year, particularly crops that tolerate cooler conditions before consistent warmth sets in. By highlighting small but meaningful timing differences across regions, the forecast aims to help gardeners plan the start of the growing season while reducing the risk of frost damage.
