Most of the Nation Will See a Toasty End to the Summer Season

The summer of 2025 has gotten off to a volatile start. Several deadly flash flooding events have paired with searing temperatures to create miserable conditions throughout much of the nation at various times. What does the late summer and early fall have in store for the U.S.? Read on for the long-range outlook.

Overall Long-Range Temperature Outlook

A new three-month outlook released last week by NOAA is providing more insight into what to expect as summer comes to an end and the fall season kicks off. While the country is nearing the dog days of summer and the peak of the heat, fall will be here before you know it.

The latest long-range outlook predicts that the bulk of the U.S. will see warmer-than-average temperatures between August and October. The northern Rockies will be no exception to this outlook with unusually warm temperatures expected for this part of the U.S. In general, the northern tier of the country will see readings that hover over historical averages through October.

Temperatures will also be slightly warmer than the norm across much of the West Coast and a zone from the southern U.S. and up into the mid-Atlantic. Although you can expect readings to hit a bit over average in these areas, the departure from normal will not be quite as significant as in the northern reaches of the country.

It will be a different situation across the Gulf Coast and into parts of the Southeast. The forecast in these regions is calling for the mercury to dip to levels cooler than average for the three-month period of August, September, and October.

Overall Long-Range Precipitation Forecast

The parts of the nation that will enjoy cooler than usual temperatures will also see precipitation levels that come in above the norm. The cooler readings will come at the hands of more cloud cover and frequent bouts of rain that naturally bring down the temperatures. This is not surprising as this is the time of the year that ushers in the peak of tropical weather activity.

Conversely, the rest of the nation is going to be dealing with conditions that trend drier than normal for the end of the summer and the start of fall. The exception to this general outlook will be across the Pacific Northwest. This corner of the country should expect precipitation levels to be slightly higher than what is typically recorded during these months. While the surge of moisture may not be good news for those with outdoor pursuits, it is a welcome sign as the peak of wildfire season also inches closer.
