Living in the southwest suburbs of Chicago, you get used to a certain level of chaos. Honestly, if you don’t like the weather in Orland Park IL, just wait fifteen minutes. It’s a cliché because it’s true. One minute you’re walking through the Orland Grassland and the sun is hitting your face, and the next, a wall of gray clouds rolls in from the west and you’re questioning every life choice that led you to leave your umbrella in the car.
It’s erratic. That’s the best word for it. We aren't just dealing with "Chicago weather" here; Orland Park sits in this specific pocket where the urban heat island of the city starts to fade, but the moisture from Lake Michigan still likes to play games with our snowfall totals.
The Reality of Our Four Seasons
Most people think of the Midwest as having two seasons: construction and winter. But it’s more nuanced than that. In Orland Park, we get the full spectrum.
Winter: The Long Slog
January is typically our coldest month. You’re looking at average highs of 32°F, but let’s be real—the wind chill is what actually kills your vibe. If you were around in mid-January 2024 or the recent cold snaps in early 2025, you remember those -30°F wind chills. That’s not just "cold"; that’s "my car won't start and my face hurts" cold.

Snow is another beast entirely. We average about 30 inches a year. However, the 2025-2026 season has already been a bit of a rollercoaster. We had that massive post-Thanksgiving storm in 2025 that dumped nearly a foot of snow on the region, followed by a surprisingly dry December. It’s the "Clipper" systems you have to watch out for. They move fast, drop three inches of fluffy stuff, and disappear before the salt trucks even hit La Grange Road.
Spring: The Great Tease
Spring in Orland Park is basically a series of lies. You’ll get a 65°F day in March where everyone goes to Centennial Park in shorts, and then it’ll snow three inches the next morning. It's muddy. It's grey. But then May hits, and suddenly everything is green. May is actually our wettest month, averaging about 4 to 5 inches of rain. If you’re planning a graduation party or a wedding at one of the local forest preserves, you basically need a Plan B, C, and D for the rain.
Why Orland Park Weather Feels Different
You might notice that it’s often a few degrees cooler here than it is at O'Hare or in the Loop. That’s because we aren't surrounded by quite as much concrete.

The open spaces like the Orland Loop and the various forest preserves allow for a bit more radiative cooling at night. This means our morning lows can be significantly crispier than what you see on the news for "Chicago."
The Lake Michigan Factor
We are far enough southwest that we don't get the "lake effect" snow as badly as, say, Indiana or even parts of the city. But the lake still influences us. In the spring, a "lake breeze" can stall out right over the southwest suburbs, keeping us ten degrees cooler than the towns just a few miles further west.
Extreme Events: It's Not Just Snow
We’ve had some weird stuff lately. Did you catch the "rare" January flash flooding earlier this month in 2026? Or the severe weather outbreak in late December 2025? It’s becoming more common to see these massive swings.

- Tornadoes: They aren't just a Kansas thing. The 2024 and 2025 seasons saw a record number of tornadoes in the NWS Chicago area.
- Heat Waves: July is usually the peak. Highs average 84-86°F, but with the humidity, the "real feel" often breaks 100°F.
- Microbursts: In June 2025, we saw 80 mph winds and massive hail in the region.
Surviving the Orland Park Climate
If you’ve lived here a while, you know the drill. But if you’re new to the area or just visiting the Orland Square Mall for a day of shopping, there are some local "rules" to live by.
First, layering isn't just a fashion choice; it’s a survival strategy. You need a base layer that wicks moisture, a middle layer for warmth, and a shell to block that biting wind coming off the open fields.
Second, watch the ice. We get a lot of "wintry mix" here. It’s that nasty combination of freezing rain and sleet that turns 159th Street into a skating rink. February 2025 was particularly brutal for this, leading to a string of accidents because of a thin "glaze" of ice that looked like just a wet road.
Practical Tips for Residents
- Check your sump pump in March. With the snow melt and the heavy April rains, if that pump fails, your basement is a swimming pool.
- Keep a "winter kit" in your car. Blanket, jumper cables, and a small shovel. If you get stuck on a side street during a heavy lake-effect burst, you’ll be glad you have it.
- Humidifiers are your friend. The indoor air in an Illinois winter is drier than the Sahara. Save your skin and your hardwood floors by keeping the humidity around 35%.
The weather in Orland Park IL is a lot of things—challenging, beautiful, and occasionally terrifying—but it’s never boring. Whether you’re bracing for the next arctic front or prepping for a humid July afternoon at the splash pad, being prepared for the shift is half the battle.
Actionable Next Steps:
Check your outdoor drainage tiles before the spring thaw begins in late February to prevent basement seepage. If you haven't swapped your wiper blades for winter-grade versions yet, do it now, as the heavy slush typical of January and February can easily snap standard blades.
