Summers are always brutal in Arizona, but the fall and winter are the best time for travelers and residents in the Grand Canyon State. However, the Old Farmer's Almanac is expecting it to be a warm fall across the United States, with occasional rain throughout the country.
While Arizonans continue to brave the summer months, here's what to look forward to in the coming season:

Most of the state is expected to be drier than usual, with rainfall remaining below average. However, the northern central area of the state from Sedona heading north is expected to have a warm and wet fall, with precipitation levels higher than the rest of the state.
How does The Old Farmer's Almanac make its predictions?
The Old Farmer's Almanac is America's oldest forecaster, according to the publication. However, its current weather forecasting method is a modern adaptation of a formula developed by the almanac's founder, Robert B. Thomas, in 1792.
The Old Farmer's Almanac specializes in extended weather predictions to help farmers plan their crops for the season using a method influenced by sunspots, which are magnetic storms on the surface of the sun, and this factored heavily into its forecasts.
How accurate are The Old Farmer's Almanac predictions?
The Old Farmer's Almanac, distinct from the Farmers' Almanac, claims an 80% accuracy rate for its weather predictions.
However, in a report evaluating last winter's forecasts, the almanac reported an overall accuracy rate of 64% for the season. The publication attributed the lower accuracy to "abnormal recent weather patterns."
