Levi's Stadium Weather: 49ers Game-Day Guide for 2026

Levi's Stadium in Santa Clara is the Bay Area's NFL stadium, and its South Bay location makes it much warmer than San Francisco. September games average highs near 81°F, while December and January games average highs near 60°F and lows near 40°F. The open-air stadium sits about 40 miles southeast of San Francisco, in the sunny South Bay rather than the foggy city. Early-season games are about heat and sun, and late-season games are about cold evenings and rain.

What Weather Should You Expect at 49ers Home Games in 2026?

The 49ers have six regular-season home games left at Levi's Stadium in 2026, and the October games are usually warm and dry, with highs in the mid-70s. The November 29 and December 13 games carry about a one-in-three chance of measurable rain. The January 3 night game kicks off after sunset, with average lows near 40°F.

The table shows long-term averages, not forecasts, so check the Santa Clara forecast about a week before a specific game. The Week 11 game against the Minnesota Vikings on November 22 is a 49ers home game played in Mexico City, not Santa Clara.

What Is the Temperature at San Francisco Bay Area Stadium?

San Francisco Bay Area Stadium, the name FIFA used for Levi's Stadium during the 2026 World Cup, is usually much warmer than San Francisco. Afternoon events in summer and early fall run in the high 70s to low 80s, and heat waves push past 90°F. Winter night events fall through the 50s into the 40s. For any event at the stadium, check Santa Clara weather, not downtown San Francisco weather.

Why Is Levi's Stadium So Hot in Early Season?

Levi's Stadium is hot early in the season because Santa Clara sits at the south end of San Francisco Bay, far from the ocean. The Santa Cruz Mountains also shield it from the marine layer, the cool ocean air that brings fog. San Francisco can be 65°F and foggy on a September afternoon while Santa Clara is in the 80s, or the 90s on hot days, under clear skies. This is the coastal-inland temperature divide that defines Bay Area microclimates.

The stadium's suite tower shades the west side, home of the 49ers sideline, while the east side faces the afternoon sun during 1:05 PM and 1:25 PM kickoffs. For September and early October games, seats on the west side are noticeably more comfortable. Sun-exposed metal and concrete also feel hotter than the air temperature.

What Is Game-Day Weather Like by Month?

September is the hottest month for 49ers games, with highs near 81°F and almost no rain. October cools to highs near 76°F and stays mostly dry. November highs average 66°F as the wet season begins. The chance of rain on a given day climbs from about 1 in 4 early in the month to 1 in 3 by late November. December and January highs average about 60°F, with lows near 42°F.

Kickoff time matters as much as the month. A 5:15 PM kickoff in mid-October starts in the 70s, and sunset comes around 6:25 PM. A 5:20 PM kickoff in early January starts after sunset, so the whole game is played as temperatures drop toward the 40s. Wind is usually light in the South Bay, so wind chill matters less here than at exposed stadiums.

What Should You Wear to a 49ers Game?

For September and early October games, wear sunscreen, a hat and light clothing, and drink plenty of water, because heat is the main weather risk. For November games, bring a light jacket, because temperatures fall quickly once the sun sets during the second half. For December and January games, dress in layers with a warm outer layer and a rain jacket. Gloves and a beanie are reasonable for a January night game.

How Often Does It Rain During 49ers Games?

Rain is uncommon at 49ers games: across a full home schedule, about one game per season has measurable rain on game day. San Jose International Airport, about 4 miles from the stadium, averages 13.48 inches of rain a year, nearly all between November and March. Santa Clara stays drier than much of the Bay Area because it sits in the rain shadow of the Santa Cruz Mountains.

The rainiest games fall in late November and December, when about one day in three is wet. Heat is still the bigger weather story at Levi's Stadium. Pack for sun early in the season and for cold and rain late in the season, and check the forecast before every game.
