Week 15 of the 2022-23 NFL season will begin on Thursday, December 15 with a crucial NFC West matchup between the San Francisco 49ers and Seattle Seahawks at Lumen Field in Seattle. This week's edition of Thursday Night Football will be streaming live from Amazon Prime.
Weather needs to be extreme to truly impact games, but when deciding between two players who you like equally, it might be a helpful tie breaker. What we really don't want to see is 20 mph or higher wind speeds. Rain can cause problems, but unless it is a combination of high winds and rain, we usually don't want to downgrade our fantasy football players too much.
Helpful weather resources include National Weather Service and Dark Sky, among others.
Weather for 49ers vs. Seahawks on Week 15 TNF
It should be a clear, cool afternoon/evening in Seattle with a high of 44 and a low of 30. There is a less than a 10 percent chance of rain and the winds are going to be light. The weather is going to be very nice for the middle of December.
Fantasy football impact
There shouldn't be much weather impact on fantasy players for TNF. With the Niners missing Deebo Samuel and question marks around QB Brock Purdy, we should see plenty of Christian McCaffrey in the run game again. He should see a ton of touches with the temps down and the Seahawks' run defense being porous.
