You think you know Minnesota weather? Sure, everyone talks about the "Bold North" and the bone-chilling winters that turn your eyelashes into tiny icicles. But honestly, weather in Ham Lake is its own specific beast. Living here, just north of the Twin Cities, means dealing with a microclimate that feels a little wilder than what you'll find down in Minneapolis.
It’s the open spaces. The sod farms. The lakes.
Without the urban heat island effect of the big city, the temperature here can drop five degrees the second you cross the city line. It’s a real thing. Ask any local who has ever left a 40-degree rainstorm in St. Paul only to pull into their driveway in Ham Lake and find two inches of slushy snow.
The Winter Reality Check
January is basically a test of will. If you're looking for the average, it's usually around 24°F for a high, but let’s be real: that’s a "warm" day. Most of the time, you’re looking at lows around 9°F. But then there are the years like 2024 and early 2026 where "Clipper" systems just won't quit.
We just saw it this January. On the 5th and 6th, we had a mess of freezing fog and ice that turned Highway 65 into a skating rink. It wasn't even a major storm, just a persistent, nasty drizzle that froze on contact. That’s the thing about weather in Ham Lake—it’s the stuff that doesn’t make the national news that actually messes up your Tuesday.
Snow is more than just a number
The official stats say we get about 48 inches of snow a year. Sounds manageable, right?
Well, it is until the wind kicks up. Because Ham Lake has so much open land and sod fields, the wind has nothing to stop it. You get "ground blizzards" where it hasn't even snowed in three days, but you can't see the hood of your truck because the wind is whipping old snow across the road.
If you're moving here, buy a snowblower. Not a little electric one. A real, gas-powered, two-stage beast. You’ll thank me in February.
Why Summer Isn’t Always a Breeze
People move here for the lakes and the outdoor space, and July is usually the payoff. It’s gorgeous. Highs average around 82°F, which is perfect for being out on the water.
But there is a trade-off.
Humidity.
In July and August, the dew point can climb into the 70s. It feels like you're walking through a warm, wet blanket. This is also when the "Ham Lake weather" shows its teeth with severe storms. Since we’re on the edge of the metro, we often sit right in the path of those bow echoes that roar across the state from the west.
Rain patterns you should know:
- June is the wettest month: Expect about 4.1 to 4.5 inches of rain.
- Storm timing: Most of our heavy hitters come in late afternoon or early evening.
- The "Sod Farm" Effect: All that flat land means you can see a wall of rain coming from miles away. It’s actually pretty cool to watch, as long as you aren’t standing in it.
The Weird "In-Between" Seasons
Spring in Ham Lake is a myth. We have "Winter," "Second Winter," and then suddenly it’s 80 degrees and the mosquitoes are the size of small birds.
Actually, April is the windiest month here. Average speeds hit around 17 mph, but gusts across the open areas are much higher. It’s that raw, damp cold that gets into your bones. You think it's over, you see a robin, and then—boom—six inches of heavy, wet slush on April 15th.

Fall, though? Fall is the secret winner.
September is arguably the best month to experience the weather in Ham Lake. The highs are around 71°F, the humidity drops off a cliff, and the bugs finally go back to whatever hole they crawled out of. It’s crisp. It’s clear. It’s why people stay here despite the -20°F wind chills in January.
What to Actually Pack (or Wear)
If you're visiting or just moved in, stop trying to look cool. Nobody cares.
In the winter, it's all about the "Ham Lake Uniform": a heavy parka (think Patagonia or Columbia), waterproof boots with actual tread, and gloves that actually work. Don't forget the ice scraper. A cheap one will snap in half the first time we get a real ice storm. Get the one with the brass blade or the heavy-duty brush.
In the summer, keep a light shell in your car. The temperature drops fast once the sun goes down, especially near the water.
Actionable Tips for Living with Ham Lake Weather
- Check the Anoka County Airport (KANE) feed: This is the closest reliable weather station. It’s only about 7 miles south of the city center and gives you a much better idea of the wind and ceiling than the general "Twin Cities" forecast.
- Seal your windows by October: Seriously. The wind here finds every crack in your siding. If you have an older home near Ham Lake or Coon Lake, those plastic window seal kits are a lifesaver.
- Watch the "Freeze-Thaw" cycle: March and April are brutal on driveways here. Because of the high water table in parts of Anoka County, frost heaves are a real pain. Keep your culverts clear of debris so the melting snow actually has somewhere to go.
- Download a high-res radar app: Since we get hit by quick-moving cells in the summer, you want something with "Future Radar" capabilities. Relying on the 6 o'clock news is a great way to get caught in a downpour at the park.
- Respect the ice: If you’re heading out on Ham Lake for ice fishing, wait until the local bait shops give the all-clear. Our weather is erratic; a few warm days in January can thin out the ice faster than you’d think.
The weather in Ham Lake is a bit of a rollercoaster, but that’s part of the charm. You just have to be prepared for the fact that "partly cloudy" might actually mean "prepare for a random blizzard." Stay weather-aware, keep your tank at least half full in the winter, and enjoy those rare, perfect 75-degree June days when they actually happen.
