Green Lake has to be one of our favorite places to enjoy the fall colors.

We know the question on your mind, Seattleites — when’s it going to get cool?

Thanks to the National Oceanic and Atmospheric Administration’s Climate Prediction Center , we know what temperatures and precipitation trends to expect in our city for September, October, and November. While exact weather conditions typically can’t be predicted more than a week in advance, here’s a seasonal outlook to help you prepare for what fall will bring.

Reminder: The first day of fall is on September 23.

Charts are showing that a majority of the United States will see higher than average temperatures this fall.

Temperature

Think warm. This fall, Seattle has a 33-40% chance of temperatures being higher than normal.

Precipitation

Expect slightly less precipitation. Seattle has a 40-50% chance of seeing below average rainfall amounts this fall.

By the month: September

Typically, the cooling off begins with daily high temperatures averaging around 67°. However, NOAA has forecasted a 95% chance of an El Niño weather pattern continuing through the winter, which typically brings warm, dry conditions to the PNW during the colder months. Summer may last a little longer this year.

Also, while our daylight hours will become outweighed by the ones we spend in the dark after the Fall Equinox, we’ll still be getting a solid 12 hours in the sun for awhile. Soak it up while you can.

By the month: October

October plunges us down into a daily high temperature average of 59°. Definitely sweater weather by this point.

By the month: November

It’s certainly turkey carving season with a daily high temperature average of 51°. But this month also brings us the dreaded end of Daylight Saving Time on Sun., Nov. 6. On this day, we’ll see a 7 a.m. sunrise and the return of the infamous 4 p.m. sunsets. Yikes.
