Farmers' Almanac Predicts Fall Weather Across All US States

The Farmers' Almanac has released its Fall 2026 weather outlook across all U.S. states. The publication predicts a warm start to autumn in September, followed by a cooling trend that spreads southward. By November, cooler temperatures will blanket most regions, with increased rain and storm systems appearing as Thanksgiving approaches.

September is expected to feel more like late summer in many areas, with warm temperatures lingering. The Northeast could experience pleasant periods, while the Southwest and much of the West remain relatively dry. Northern states may see early signs of a seasonal shift during September, with colder, winterlike conditions arriving earlier in the North Central states and Great Lakes region, potentially bringing snow by mid-October.

The Southwest will start the season with typical heat, followed by more significant cooling in October, while the Southeast will stay warmer for a longer period, with temperatures dropping noticeably later in the fall. Colder air is expected to spread across the country by November, including parts of the South. The Almanac forecast also anticipates a wetter late fall, with frequent rain and storm systems before Thanksgiving.

Northern regions can expect fall to arrive more abruptly, transitioning from a milder start to colder and wetter conditions. The Almanac does not provide long-range forecasts for Alaska and Hawaii due to their stable climate patterns and varied terrain. The forecast map summarizes the region-specific predictions, with higher elevations in northern states expected to see snow by mid-October.

The Almanac's long-range weather predictions are based on a formula developed in 1818 by founder David Young, which includes sunspot cycles, solar activity, lunar influence, planetary positions, and comparisons between past weather patterns and current conditions. The forecast is calculated two years in advance and remains unchanged after publication.
