New England weather is basically a mood ring. You wake up in Foxborough thinking it’s a light jacket kind of day, and by noon, you’re reconsidering your entire life’s wardrobe choices. Honestly, if you've ever stood in the middle of a parking lot at Gillette Stadium, you know exactly what I’m talking about. The temperature in Foxboro MA isn't just a number on a screen; it’s a tactical challenge for anyone living here or just passing through for a game.
Right now, as we sit in mid-January 2026, the mercury is doing its usual winter dance. Today, January 17, we're looking at a current temperature of 40°F, though it feels more like 35°F thanks to a 7 mph breeze coming off the south. It’s cloudy, kind of damp, and there’s a 72% chance of light snow later.

The Gillette Effect: Why 40 Degrees Feels Like 20
There’s a specific phenomenon I like to call "Stadium Chill." You can look at the forecast and see 42°F for a high—which is exactly what we have today—but once you get inside that massive concrete bowl of Gillette Stadium, the rules change. The wind tunnels created by the architecture can make a manageable afternoon feel absolutely biting.
Sunday, January 18, is a perfect example of why you can't trust a single number. The forecast high is 35°F, but with snow expected and humidity hitting 91%, that cold is going to seep right into your bones. If you're heading to the Patriots-Texans game, don't be fooled by the "high." By the 3:00 PM kickoff, we're expecting temperatures to hover right around freezing. For those dome-dwelling teams from Houston, this is a nightmare. Historically, dome teams playing in sub-freezing outdoor playoff games are a dismal 2-15 since the turn of the century.
Seasonal Reality Check
Most people assume Foxboro is just "cold" because of the football highlights they see on TV. That's a mistake.
In the summer, specifically July, the temperature in Foxboro MA can actually be quite pleasant, averaging a high of 82°F. It rarely breaks past 91°F, though the humidity can make it feel like a tropical greenhouse. July 21 is statistically the hottest day of the year here. You go from needing a heavy parka in January—where the average low is a shivering 19°F—to wearing a sleeveless shirt and hunting for shade in less than six months.
The transition seasons are where things get weird.
- Spring (March–May): You’ll see a jump from 45°F in March to 66°F in May. It’s "mud season," and the temperature swings can be 30 degrees in a single day.
- Fall (September–October): This is the sweet spot. Highs in the 60s and 70s. It's the best time to visit, but by late October, you better have a sweater handy.
The Microclimates of Norfolk County
Foxboro sits at an elevation of about 295 feet. It’s not the Himalayas, but it’s high enough to catch different weather than coastal Boston or the flatter lands of Rhode Island. Sometimes we get "ocean air" that moderates the temperature, but more often, we’re just far enough inland to miss the warming effect of the Atlantic while still catching all the moisture.
If you look at the next few days, you can see the volatility:
Monday, Jan 19: High 30°F, Low 17°F (Sunny but crisp).
Tuesday, Jan 20: High 25°F, Low 11°F (Actually freezing).
Thursday, Jan 22: High 42°F, Low 19°F (A 23-degree swing).
This isn't just "weather"; it's a test of endurance for the town's infrastructure. Local reports from the Foxborough Conservation Commission have noted that these intense swings—going from a deep freeze to a rapid thaw—strain the aging culverts and dams like Crackrock Pond. When it hits 42°F after a week of snow, all that runoff has to go somewhere, and usually, that somewhere is the Cocasset Street underpass.
How to Actually Dress for Foxboro
Forget fashion. If you’re here in the winter, it’s about air pockets. Layers aren't just a suggestion; they are a survival strategy.
- The Base: Wicking material. If you sweat while walking from the parking lot and then sit still in the stands, you will freeze.
- The Mid: Fleece or wool.
- The Shell: Something that breaks the wind. In Foxboro, the wind is the real enemy, especially those 13-14 mph gusts we’re expecting from the northwest early next week.
Honestly, the biggest mistake people make is looking at the "High" and thinking that’s what they’ll experience. In the winter, the sun sets early—around 4:30 PM in January—and the temperature drops like a stone the second the light fades. By Tuesday night, we’re looking at 11°F. That is "stay inside and order a pizza" weather.
Navigating the Forecast
If you are planning a trip or just trying to get through the work week, keep an eye on the "Feels Like" or "RealFeel" index. For Sunday's game, while the air temp is 35°F, the RealFeel is pegged at 28°F. That seven-degree difference is the difference between "I'm okay" and "I can't feel my toes."
Always check the wind direction too. A south wind (like we have today) usually brings moisture and "warmer" air, while a northwest wind (coming Monday/Tuesday) is the "Arctic Express" that brings the dry, biting cold.
Actionable Insights for Your Visit:
- Check the Dew Point: If it’s high in the summer, expect heavy humidity at Patriot Place.
- Game Day Prep: If the forecast says snow (like it does for tomorrow), arrive early. The temperature drop during the game will turn slush into ice quickly.
- Infrastructure Watch: Avoid the East Street and Cocasset Street areas during rapid thaws or heavy rain; they are notorious for localized flooding and freezing.
Stay warm, keep a scraper in your car, and never trust a clear sky in Norfolk County without checking the barometer first.

Next Steps:
To prepare for the upcoming cold snap, you should check your car's antifreeze levels and ensure your outdoor pipes are insulated before Tuesday's drop to 11°F. If you are heading to Gillette Stadium this weekend, prioritize wind-resistant outer layers to combat the 11 mph southern gusts and expected snow.
