If you tell someone you’re moving to the Twin Cities, they usually react like you’ve just announced a permanent relocation to the dark side of the moon. "The frozen tundra," they’ll say, shivering vicariously. "Better stock up on thermal underwear."
And look, honestly? They aren't totally wrong. I’ve seen days in January where the air feels less like weather and more like a personal attack. But if you’re only looking at the scary headlines or the -20°F wind chills, you’re missing the bigger picture. The average temperatures in Minneapolis tell a story of extreme mood swings, sure, but also some of the most spectacular summer and fall days you’ll find anywhere in the country.
The Big Freeze: Surviving the Winter Averages
Let’s start with the elephant in the room. Winter here isn’t just a season; it’s a lifestyle. When we talk about January, the coldest month, the average high is around 24°F and the average low sits at 10°F.
That sounds manageable on paper.

But averages are liars. In reality, Minneapolis weather is a see-saw. One week you might have a "heat wave" where it hits 35°F and everyone is out in light hoodies, and the next, the polar vortex sweeps in and drops the mercury to -15°F before you can even find your scraper.
According to data from the Minnesota DNR, the Twin Cities hit the 0°F mark (or lower) about 23 days a year. It’s a dry cold, which locals will tell you is "better," but when the wind kicks up across the flat plains, the wind chill formula—which the National Weather Service calculates based on heat loss from exposed skin—can make 0°F feel like -20°F in a heartbeat.
Why January Isn't Always the Villain
Believe it or not, late December and February often feel tougher because the snow has had time to turn into that grey, frozen slush. January, at least, usually has high-pressure systems that bring blindingly bright blue skies. We call them "sun dogs"—ice crystals in the air that create halos around the sun. It’s beautiful, even if your nose hairs are freezing together.
The Great Thaw: Spring is a Myth
In Minneapolis, spring doesn't really exist. We have "Second Winter," "The Mud Week," and then suddenly, it's 80 degrees.
March is a chaotic month with an average high of 42°F. It’s the month where you’ll see someone in a parka walking next to a college kid in cargo shorts. We’re all just desperate. April starts to feel more human with an average high of 58°F, but don't get cocky. As recently as 2018, the city got smashed with a record-breaking 15-inch blizzard in the middle of April.
Basically, don't put your shovel away until May.
Summer: The Best Kept Secret in the Midwest
If you’ve never been to Minnesota in July, you’re missing out on something special. While the rest of the world thinks we’re shivering, we’re actually roasting. The average high in July is 83°F, but it’s the humidity that gets you.
Being the "Land of 10,000 Lakes" means there is a lot of moisture in the air. When the dew point climbs into the 70s, it feels "muggy" or "oppressive." We rely on the Heat Index—a measure of how hot it actually feels—which can easily push perceived temperatures into the 90s or even 100s.
The August Sweet Spot
Most people aim for July, but August is secretly better. The average temperatures stay warm—around 80°F—but the nights start to get a little crisper. It’s perfect for the Minnesota State Fair, which is basically the center of the universe for twelve days at the end of the month.
Fall: The Most Reliable Season
If you want the most predictable average temperatures in Minneapolis, come in September or October.
- September: Highs average 71°F. It’s the goldilocks zone.
- October: Highs drop to 58°F. This is peak "sweater weather."
The fall colors usually hit their stride in early October. The air is dry, the sky is deep blue, and the biting insects have finally died off. It’s easily the most comfortable time to be outside.
The Records That Broke the Averages
To really understand Minneapolis, you have to look at the extremes. The state record for the highest temperature is 115°F (set in 1917), while the lowest is -60°F (set in 1996 in Tower, though the Twin Cities hit -34°F the same year).
That’s a 175-degree swing.

That volatility is why we have the Skyway system—nearly 10 miles of enclosed, second-level footbridges connecting buildings downtown. It allows people to work, eat, and shop without ever touching a snowflake.
Planning Your Trip: What to Pack
| Season | What the Averages Say | What You Should Actually Pack |
|---|---|---|
| Winter | 10°F to 25°F | Heavy down parka, wool socks, and a sense of humor. |
| Spring | 35°F to 55°F | Layers. Literally all of them. A waterproof shell is key. |
| Summer | 65°F to 83°F | Shorts, but keep a light sweatshirt for the A/C. |
| Fall | 40°F to 70°F | Boots, flannels, and a camera for the leaves. |
Actionable Next Steps for Travelers or New Residents
If you’re trying to time a move or a visit based on these average temperatures in Minneapolis, here is what you actually need to do:
- Download the "MN DNR" or "MPR Weather" apps: Local meteorologists like Paul Huttner or Sven Sundgaard understand the local lake-effect and "urban heat island" nuances better than national apps.
- Invest in "The Gear": If you’re here for winter, don't buy a cheap coat. Look for something with a high "fill power" rating. If your feet are warm, the rest of you will be fine.
- Monitor the Dew Point, Not Just the Temp: In the summer, a 90°F day with a 50°F dew point is gorgeous. A 80°F day with a 75°F dew point is a swamp.
- Embrace the "Shoulder" Months: If you want to save money on hotels and avoid crowds, May and September offer the best weather-to-price ratio.
The weather here is a conversation starter. It’s how we bond with strangers at the bus stop. It might be unpredictable, but it’s never boring. Just remember: there’s no such thing as bad weather, only bad clothing.
