We know the question on your mind, Seattleites — when’s it going to get cooler?
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 Sunday, Sept. 22.
Temperature
It’s a toss-up. This fall, Seattle has equal chances of temperatures being higher or lower than normal.
Precipitation
Expect slightly more precipitation. Seattle has a 40-50% chance of seeing above 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 66% chance of a La Niña weather pattern beginning sometime between September and November, which typically brings wetter + chillier temps to the Pacific Northwest.
Also, while our daylight hours will become outweighed by the ones we spend in the dark following the Fall Equinox, we’ll still be getting a solid 12 hours in the sun for a while. Soak it up while you can.
By the month: October
October plunges us down into a daily high temperature average of 59°. It will definitely be sweater weather by this point.
By the month: November
We’ll lead into turkey carving season with a daily high temperature average of 51°. This month also brings us the dreaded end of Daylight Savings Time on Sunday, Nov. 3. On this day, we’ll see a 7 a.m. sunrise and the return of the infamous 4 p.m. sunsets. Sorry, we hate to be the bearers of bad news.
