Living in Mound, Minnesota, means you basically live on a boat or a snowmobile depending on which month it is. It’s a town defined by Lake Minnetonka. Honestly, if you aren't checking the wind speed or the ice thickness, are you even living here? The weather in Mound MN is famously dramatic, swinging from bone-chilling arctic blasts in January to those humid, heavy-air July days where the only escape is jumping into Cook’s Bay.
It's not just "Minnesota cold." It's a specific kind of lake-adjacent atmosphere.
Why the weather in Mound MN feels different
Most people think all of the Twin Cities metro area shares the same forecast. That's kinda true, but Mound has a personality. Because the city is wrapped around the bays of Lake Minnetonka, the water acts like a massive thermal battery. In the late fall, the lake stays warmer than the air, sometimes creating weird local fog or even "lake-effect" flurries before the ice sets in.
By the time January 2026 rolled around, we saw just how weird things could get. On January 8-9, a bizarrely warm system moved through. Instead of the usual blizzard, Mound saw record-breaking rain. We're talking totals over 1.2 inches in some spots—an absolute anomaly for a month that usually averages only about 0.8 inches of total precipitation. The ground was just warm enough that the rain soaked in rather than causing a massive ice rink on the roads, which was a lucky break for anyone commuting on County Road 15.

The deep freeze and the "Ice Out" obsession
Winter here isn't a season; it's a lifestyle. January is traditionally the toughest stretch. The average high struggles to reach $24°F$, and the lows often dip to $9°F$ or colder.
- January: The coldest month. Expect about 8-9 inches of snow.
- December: Usually the snowiest month, averaging 13 inches.
- February: Windy, gray, and the cloudiest month of the year.
The big conversation every spring is the "Ice Out." In 2025, it happened on March 29. That was early. The median date is usually closer to April 14. When the Hennepin County Sheriff’s Office finally declares the lake clear, the energy in Mound shifts instantly. It's like the whole town wakes up from a long nap.
Summer storms and lake life
Once you hit June, the weather in Mound MN turns into a tropical-Midwest hybrid. June is actually the wettest month of the year, averaging about 5 inches of rain. These aren't just drizzles; they are those classic, house-shaking thunderstorms that roll across the lake.

You've got to watch out for the humidity. In July, the dew points can climb high enough to make the air feel thick. July is the hottest month, with average highs around $82°F$, but on the water, it always feels a bit better.
"Ice out is observed on Lake Minnetonka when a patrol boat can safely navigate each bay and channel throughout the 14,528 acre lake." — Freshwater Society.
Is Mound at risk for severe weather?
Statistically, Minnesota averages about 46 tornadoes a year. While Mound has a "very low" storm event risk score according to data from Augurisk, no one forgets the 1965 outbreak that hit the west metro. The real daily threat is usually hail or high winds that can whip up waves on the lake, making boating dangerous for the inexperienced.

Practical tips for surviving Mound’s climate
If you’re moving here or just visiting, forget the fashion. It’s all about utility.
- The Layer Rule: In October or April, it might be $30°F$ at sunrise and $60°F$ by 2:00 PM. If you aren't wearing layers, you're going to be miserable.
- The Wind Chill Factor: A 10 mph wind in Mound feels a lot sharper when it’s blowing across an open frozen bay. Invest in a wind-rated parka.
- Sump Pump Check: Because Mound has a high flood risk score (around 67), especially near lower-lying lake lots, make sure your pump is working before the March melt.
- Boating Safety: Check the "Small Craft Advisory" before heading out. Lake Minnetonka can go from glass-smooth to whitecaps in twenty minutes when a cold front moves in from the Dakotas.
What to expect for the rest of 2026
The long-range outlook suggests summer 2026 might be slightly cooler and drier than average. That sounds like a win for anyone who hates the "muggy" days. September and October are looking like the sweet spot—crisp air, clear skies, and the best time to see the leaves change along the shorelines of Harrison Bay and Lost Lake.
Basically, Mound is beautiful, but it demands respect. Whether you're dodging a January snowstorm or catching a July sunset, the weather is the main character here.
Your next steps for Mound weather prep:
- Check the current lake level if you own a dock; spring rains can fluctuate heights quickly.
- Sync your calendar with the official Hennepin County "Ice Out" tracker to prep your boat for the season.
- Inspect your roof and gutters now, before the heavy June thunderstorm cycle begins.
