October Weather Outlook: Warmer Than Average Temps for Most of US

Temperatures are expected to spike toward August-like heat in some northern areas, while most of the US will see above-average conditions during October, with the exception of the extreme West, Arizona, and Florida.

The factor driving the above-average temperatures is the development of La Niña, which forecasters say will emerge this fall and continue into winter. La Niña is when equatorial Pacific Ocean waters cool, and depending on its strength, can influence global weather patterns, particularly in the US. When a La Niña has developed in October, the typical result is above-average temperatures across much of the lower 48.

However, at the same time, areas along the West Coast and Gulf coasts will typically experience cooler than average conditions. Forecasters say such a scenario closely matches the current outlook for October.

With the exception of the extreme West, Arizona, and Florida, it may not feel like fall in the lower 48. Most of the nation should expect temperatures above normal during the month of October, according to the latest forecast by the Weather Company.
