Here is our August monthly snapshot of the U.S. and Canadian Weather forecasts. 

Keep in mind that the forecasts presented below are based on “long range” weather predictions, which means that they were created many months ago to help gardeners, travelers, and weather watchers plan ahead. See how The Old Farmer’s Almanac predicts the weather.

So, we would advise treating long range predictions as you might trends, giving you a general sense of typical weather and how much the season might deviate from normal. Weather patterns can shift by a week and unexpected dynamics can occur. Ever year is different! That said, The Old Farmer’s Almanac is traditionally 80% accurate, having predicted weather since George Washington’s days as president.
