NFL Week 21 Weather & Betting Lines

Week 21 · 2 games · January 25, 2026 · Updated Jul 8, 11:59 PM ET

The Almanac's Take

Two outdoor games this week, both with weather worth flagging. Denver is the sharper story: 26 degrees and a 43.5 total at Mile High, where New England visits as a 3.5-point underdog. That's a cold-weather number that already feels cautious — hand-numbing temps historically compress passing efficiency, and neither offense gives you much reason to expect fireworks anyway. Seattle sits milder at 41 degrees with virtually no wind (2 mph), and the Rams are 2.5-point favorites at Lumen Field under a 45.5 total — the conditions there are close to neutral, so that line lives and dies on the matchup itself.

Methodology

Conditions and venue come from the nflverse schedules feed. Temperature and wind are shown only when forecast — they are blank (never zero) for dome/closed-roof games and for outdoor games whose forecast hasn't posted yet. The spread is shown in favorite form; a positive home line in the source feed means the home team is favored. Lines are the market's, for context — not a betting recommendation.
