Mid October Climate Outlook
What’s Next for the Pacific Northwest?
Wetter than normal conditions most likely November through January.
The Climate Prediction Center’s monthly outlook for November 2025 brings continued uncertainty in temperatures, although most of the western and south central United States are likely to be above normal. Precipitation shows slightly higher changes of wetter than normal conditions statewide (33-40%). These elevated chances of wetter than normal conditions are due in part to the presence of weak La Niña conditions in the Pacific.
The seasonal forecast for November through January once again shows uncertainty in temperatures with equal chances of above, near, or below normal conditions. On the other hand, precipitation shows fairly high chances of wetter than normal conditions with a 40-50% chance of wet conditions as La Niña conditions continue through this period.
La Niña conditions have arrived
The CPC has announced a La Niña advisory indicating that La Niña conditions (cooler than normal sea surface temperatures in the Tropical Pacific) have arrived. As this pattern in the Pacific begins to influence the weather in our neck of the woods, we are expecting wetter than normal conditions through the first half of the wet season. This La Niña event is still likely to be weak and brief, likely ending in late winter or early spring.
