If you’ve lived in the Chicago suburbs for more than five minutes, you know the drill. One day you’re wearing a parka, the next you’re thinking about a light windbreaker, and by 3:00 PM you’re sweating in your car. It’s wild. The weather in Glenview Illinois is basically a masterclass in variety. Situated just far enough from Lake Michigan to miss some of the direct "lake effect" cooling but close enough to still feel the dampness, Glenview has its own little rhythm.
It's unpredictable. Honestly.
You have these gorgeous, leafy summers where the Glenview Park District pools are packed. Then you have January, where the wind coming off the open fields near the old Naval Air Station land (The Glen) feels like it’s trying to personally insult you. Understanding the local climate isn't just about checking an app; it’s about knowing when the "Lake Breeze" is going to kill your afternoon BBQ.
The Seasonal Rollercoaster in 60025 and 60026
Glenview hits all four seasons, and it hits them hard. There is no such thing as a "mild" transition here. We don't do subtle.
Winter: The Long Haul
January is the undisputed heavyweight champion of misery. The average high struggles to reach 32°F, while lows hover around 20°F—and that’s a "warm" night. In 2025, we saw a string of arctic fronts in late December that dropped temperatures into the single digits.
Snow is a weird beast here. You’ll get years where it feels like you're shoveling every other day, and then you’ll get a "dry" winter where it’s just gray and crunchy. On average, Glenview gets about 38 inches of snow a year. The "Lake Effect" snow usually hits cities further east like Wilmette or Evanston harder, but when the wind shifts just right, Glenview gets dumped on.
Spring: The Great Tease
Spring is barely a season. It’s more like a three-month-long argument between winter and summer. You’ll have a 70-degree Tuesday in April, then wake up to a dusting of snow on your tulips on Wednesday.
Rain picks up significantly in May. We’re talking about 3.4 inches of rainfall on average. This is when the ground gets that specific "Glenview mush" feel. If you’re a gardener at Wagner Farm, you know you don't put anything in the ground until Memorial Day unless you want to lose your investment to a random frost.
Summer Heat and the "Lake Effect" Myth
July is the hottest month, with highs averaging 83°F or 84°F. But averages are liars. You’ll frequently see stretches of 90-degree days with humidity that makes the air feel like a warm wet blanket.
- Hottest day: Usually hits in late July.
- The Breeze: Sometimes, you get a "Lake Breeze" that cools the eastern side of town by 10 degrees while the western side near I-294 is still baking.
- Humidity: It’s real. Blame the cornfields further west and the proximity to the Great Lakes.
Is Glenview Actually in a Tornado Alley?
Short answer: No. Long answer: Sorta.
Illinois as a whole averages about 54 tornadoes per year. While Glenview isn’t in the heart of the "classic" tornado alley, the Chicago suburbs are seeing more frequent severe weather events. Just last July (2024), a massive outbreak spawned 32 tornadoes in the Chicago area—a record-breaking day.
Most of our "scary" weather is actually straight-line winds and severe thunderstorms. According to climate risk data, nearly 100% of homes in Glenview have at least some risk of wind damage from these systems. When those sirens go off, people actually listen. We've had historical wind gusts hitting 100 mph in the past (looking at you, June 1990).

Severe Weather Survival
If you’re new to town, here’s the reality:
- Sirens: They test them on the first Tuesday of every month at 10:00 AM. If you hear them then, it's a test. If you hear them any other time, get to the basement.
- The Glen Effect: Because the redevelopment of the old Naval Air Station created a lot of open space and large paved areas, some locals swear the wind kicks up more intensely in that part of town.
- Flash Flooding: With over 37 inches of annual rain, some of the older parts of Glenview with aging sewer systems can see street flooding during those heavy June downpours.
When is the Best Time to Actually Enjoy Glenview?
If you’re planning a visit or a wedding at the Heller Nature Center or a big outdoor event at Gallery Park, aim for September.
September is basically perfect. The humidity dies down, the average high is a comfortable 74°F, and the bugs finally take a hike. It’s the sweet spot before the "Grey Period" of November hits. Early June is also great, but you run the risk of those massive Midwestern thunderstorms that can ruin a party in twenty minutes.
Practical Tips for Living with Glenview Weather
Weather in Glenview Illinois requires a specific kind of preparedness. You can't just have a coat; you need a "coat system."
- The Car Kit: Always keep a scraper, a small shovel, and a blanket in the trunk. Even if it’s March. Especially if it’s March.
- Drainage: Check your gutters in October and again in April. The heavy spring rains will find every leak in your house.
- Summertime Electricity: Be ready for the occasional power outage during those big July storms. ComEd is usually fast, but those old-growth trees in the East Glenview neighborhoods love to fall on power lines.
Basically, the weather here is a test of character. It’s why we’re so obsessed with talking about it at the grocery store. It changes so fast that if you don't like it, you really can just wait an hour.
