If you’ve lived around the 60526 zip code for more than a week, you know the drill. You wake up to a crisp 40-degree morning, and by noon, you're peeling off layers because the humidity decided to show up uninvited. La Grange Park weather is a fickle beast. It’s the kind of climate that keeps local HVAC companies in business year-round and makes "garage fridge" season a legitimate calendar event.
Honestly, people often lump us in with Chicago's general forecast, but there’s a nuance to being just inland enough to miss the lake breeze but close enough to feel the "lake effect" snow. We aren't just "Chicago-lite."
The Reality of the "Four" Seasons
We don’t really have four seasons. We have two long ones, a "don't blink or you'll miss it" spring, and a fall that feels like a glorious apology for the previous six months.
January is the heavyweight champion of misery here. It’s gray. The sky in La Grange Park during January is overcast about 57% of the time. You’ll go days without seeing the sun, and the temperature typically bottoms out around 19°F, though we’ve all seen those polar vortexes that make 19 degrees feel like a tropical vacation. January 29 is historically the coldest day of the year. If you’re planning a move, maybe don’t pick that week.
Then comes the "Spring." I use quotes because spring in La Grange Park is basically a series of mud puddles and "false starts." One day it’s 65 and you’re at Memorial Park thinking about the grill, and the next day there’s a literal inch of slush on your windshield. May 24 is statistically the wettest day of the year, with a 37% chance of precipitation. It’s rainy. It’s unpredictable. It’s Illinois.

The Summer Steam
By the time July rolls around, the humidity is the real story. The hottest day usually hits around July 19, with highs averaging 84°F. That doesn’t sound too bad on paper, right? Wrong.
The dew point is what kills you. Because we’re tucked away in the suburbs, away from the immediate cooling effect of Lake Michigan, we can get that stagnant, "thick" air. It’s the kind of heat where you walk outside and immediately feel like you need a second shower.
- Warmest month: July (Highs of 83-84°F)
- Humid days: Expect "muggy" conditions from June through September.
- Clear skies: August is actually our sunniest month, with clear or partly cloudy skies 68% of the time.
Why La Grange Park Weather Still Matters for Homeowners
If you own a home here, the weather isn't just about what jacket to wear. It’s about your basement.
The Village of La Grange Park takes flooding seriously because we’ve seen what happens when those spring storms dump three inches of rain in two hours. The "South Basin" and "Maple Avenue Relief Sewer" projects weren't built for fun; they were built because the local geography makes us prone to drainage headaches.

Basically, if you have a finished basement, you need a battery backup for your sump pump. No exceptions. When the power flickers during a June thunderstorm, that $150 battery is the only thing standing between you and a very expensive carpet replacement. The village even offers a Sewer Backup Prevention Grant—which most people don't even realize exists—to help residents install things like overhead sewers or backwater valves.
The Winds and the Sirens
We live in a part of the country where the wind is a constant companion. In January, you’re looking at average wind speeds of around 11 knots, with gusts that can easily top 30. It makes the "real feel" temperature significantly lower than what your phone tells you.
And then there are the sirens.
Every first Tuesday of the month at 10:00 AM, the Village tests the sirens. It’s a localized tradition that scares the life out of newcomers but barely registers for the rest of us. But when those sirens go off at 3:00 PM on a humid Wednesday? That’s when you head to the basement. Tornado season is a real thing here, peaking between April and June, and while we haven't had a "big one" in the immediate village lately, the risk is always there.

- Basement protocol: Get under something sturdy like a heavy workbench.
- The "Third Floor" Rule: If you're in one of those beautiful old Victorians, get to the lowest level. Windows are the enemy.
- Hydrant Clearing: In the winter, if you have a fire hydrant on your parkway, clear a 3-foot path around it. It's not just a nice gesture; it’s a safety requirement for the Fire Department.
Snow: The Love-Hate Relationship
Snowfall in La Grange Park usually totals around 30 to 40 inches a year, but it never comes in neat, manageable increments. It comes in a 10-inch "Clipper" that shuts down the Metra or a "Wintry Mix" that turns La Grange Road into a skating rink.
The village is actually pretty efficient at plowing, but they have a specific order of operations. Main roads first, then side streets. If you park on the street during a 2-inch snowfall, expect a ticket or a very frustrated plow driver.
What to Actually Expect
If you're visiting or moving here, don't trust a forecast more than three days out. Seriously.
The proximity to the city creates a "heat island" effect, but our lush tree canopy—which is one of the best things about La Grange Park—actually helps keep the neighborhood a few degrees cooler than the concrete jungle of downtown Chicago.
Actionable Prep for 60526 Residents
- Check your sump pump today. Don't wait for the May rains. Dump a bucket of water in the pit and make sure it kicks on.
- Download the "Rave Smart 911" app. The village uses this for emergency weather alerts that are more specific than the national ones.
- Audit your trees. With our high winds, dead branches over your roof are a disaster waiting to happen. Get an arborist out before the spring storms hit.
- Winterize by November. If your outside spigots aren't drained by Thanksgiving, you're playing Russian Roulette with your pipes.
La Grange Park weather is a test of endurance and preparation. It’s frustrating, beautiful, and wildly inconsistent. But hey, at least we don't have to deal with hurricanes.
To stay ahead of the next big shift, keep a "go-bag" in your basement and a snow shovel in your trunk. The transitions here happen fast—sometimes within a single afternoon—and being the person with the scraper already in their hand makes all the difference when the sleet starts falling.
