You’ve heard the jokes. If you don’t like the weather in Iowa, just wait five minutes. It’s the ultimate Midwestern cliché, but honestly? It’s kinda true. When you’re looking at the weather Des Moines Iowa offers, you aren’t just looking at a forecast. You’re looking at a chaotic, beautiful, and sometimes terrifying drama that plays out over 365 days.
People think they know what "cold" means until they're standing on Court Avenue in mid-January with a wind chill of -25. Or they think they understand "humidity" until a July afternoon turns the air into a warm, wet blanket that you can’t escape, even in the shade.
The Frigid Reality of January in Des Moines
Right now, as we move through January 2026, the city is caught in a classic Iowa tug-of-war. Today, January 18, we’re dealing with a massive cold front. The National Weather Service in Des Moines actually issued a Winter Weather Advisory because light snow and gusty winds are turning visibility into a mess.

If you're driving up I-235 or heading toward Ankeny tonight, it’s going to be brutal. We’re talking wind chills dropping to the teens or even twenties below zero. That’s not just "chilly." That’s the kind of cold that makes your nose hairs freeze the second you step out of the car.
Why the Wind is the Real Villain
In the 515, the temperature is a lie. The wind is the truth. Des Moines sits in this open stretch of the Heartland where the wind has nothing to stop it.
- Average January Highs: Usually around 31°F.
- The Wind Factor: 17 mph is the average wind speed this month.
- The Result: That 31°F feels like 12°F on a good day.
I remember a few years back—2024 to be exact—when we hit a blizzard in mid-January that basically shut the state down. People were trapped in their homes for days. We're seeing similar patterns this year. The "Almanac" folks predicted a snowstorm for late January 2026, and looking at the current radar streaks coming down from Minnesota, they might be right on the money.
Spring: The Season of "Maybe"
Spring in Des Moines is a myth. Or rather, it’s a series of two-day windows where the world is perfect, sandwiched between a random snowstorm in April and a 90-degree day in May.
Actually, the most dangerous part of weather Des Moines Iowa gets isn't the snow. It’s the severe weather season. Last year, in May 2025, a massive derecho ripped across the state. These aren't just "storms." They’re inland hurricanes. Straight-line winds over 70 mph can flatten a cornfield—or a suburban fence—in seconds.
If you're visiting in the spring, keep a weather app pinned to your home screen. When those sirens go off, Iowans don't always run for the basement (we usually go to the porch to look for the funnel), but you probably should. The Des Moines metro has a history with tornadoes, including the nasty ones that hit the eastern edge of the city back in July 2024.
Summer is a Steam Room
By the time the Des Moines Arts Festival rolls around in June, the "freezing" part of the year is a distant memory. Now, you’re dealing with the corn sweat.
That’s a real thing.
Millions of acres of corn surrounding Des Moines transpire moisture into the air. It’s why our dew points hit the 70s and stay there. It’s a thick, heavy heat. July is statistically our hottest month, with average highs of 86°F. But with that humidity? It feels like 100°F.
Basically, you go from one extreme to the other.
The Best Time to Actually Be Outside
If you want the "Golden Retriever" of weather—friendly, reliable, and perfect—you come to Des Moines in September or October.
The humidity breaks. The sky turns this piercing, high-altitude blue. The highs sit in the 60s and 70s. It’s the only time of year where you don’t need a parka or a gallon of industrial-strength deodorant just to walk to your mailbox.
But even then, Iowa likes to keep you on your toes. I’ve seen it snow on Halloween more than once.
Practical Tips for Surviving the 515
If you’re moving here or just passing through, here is how you handle the weather Des Moines Iowa throws at you:

- The Layering Rule: If you wear one big coat over a t-shirt, you’ve lost. You need a base layer, a mid-layer (fleece is king), and a windproof shell.
- Tires Matter: Iowans act like they’re experts at driving in snow, but half of them are sliding into the ditch on I-80. If you don't have all-wheel drive, at least get good tires.
- The "Salt" Factor: Your car will turn white in the winter. It’s not snow; it’s salt. Wash it off immediately or your wheel wells will disappear into rust by 2028.
- Hydrate in Summer: The heat index here is no joke. People collapse at the Iowa State Fair every single year because they underestimate the "moist" heat.
The truth is, Des Moines is a city of extremes. We deal with the "Polar Vortex" and the "Heat Dome" in the same year. It builds character, or at least gives us something to talk about while we’re standing in line at Hy-Vee.
What to Do Next
Keep a close eye on the local NWS Des Moines office updates. For the rest of this week, we’re looking at a brief warmup on Tuesday into the 30s before another "cold plume" drops down for the weekend. Check your furnace filters now. If you're traveling, make sure you have an emergency kit in your trunk—blankets, a shovel, and some extra gloves. Iowa weather doesn't forgive a lack of preparation.
