Early August Climate Outlook

ENSO-neutral conditions are likely to continue through October according to the Climate Prediction Center (CPC). Neutral conditions make it more difficult to predict upcoming fall conditions. There are roughly equal chances of either La Niña or neutral ENSO conditions for the upcoming winter, with much lower chances of El Niño conditions.  

The 1-Month August outlook indicates low predictability for precipitation with equal chances of above, below, or near-normal precipitation, shown by the lack of shading. Above normal temperatures are expected to continue through August with a 40-50% chance of above normal temperatures statewide.

Similarly, the 3-Month outlook (August-September-October) also shows equal chances of above, below, or near-normal precipitation. As for temperatures, above normal temperatures are favored to continue from August through October with a 40-50% chance of warmer than normal temperatures across much of the state and a 33-40% chance of warmer than normal conditions across the Olympic Peninsula, the far northern Cascades, and the central and northern Puget Sound.
