If you’ve spent any time in the south suburbs of Chicago, you know the drill. One minute you’re enjoying a crisp autumn walk through 175th Street, and the next, a "Clipper" system is dumping three inches of slush on your driveway. Honestly, the weather in Hazel Crest isn't just a topic for small talk at the local Jewel-Osco; it’s a survival skill.
People usually lump us in with the city. They assume if O'Hare is seeing a blizzard, we are too. But Hazel Crest has its own weird micro-climatic quirks. Being tucked into that specific pocket of Cook County means we deal with lake effect leftovers, humidity that feels like a wet blanket, and spring winds that could knock a toddler over.
The Reality of the Hazel Crest Seasons
Most outsiders think it's just "cold" or "hot." It is way more nuanced than that. We basically live through four distinct acts of a very chaotic play.
Winter: The Long Haul
January is, without a doubt, the toughest month here. According to data from the Illinois State Climatologist, temperatures in our area often bottom out with an average low of 19°F. But that’s just the "official" number. You’ve felt that wind chill coming off the open spaces near the bypass. It’s biting.
Snow isn't the only problem. We average about 31 inches of the white stuff annually. However, the real killer in Hazel Crest is the gray. In January, the sky is overcast or mostly cloudy about 58% of the time. It’s the kind of gloom that makes you forget what the sun looks like until March.
The "Fool’s Spring"
March and April are liars. You’ll get a 65-degree day where everyone is out in shorts at the park, and then forty-eight hours later, it’s 28 degrees and sleeting. This is when the "Windy City" reputation really hits home for us. Average wind speeds in the spring hover around 18 mph, but gusts frequently top 40 mph during those messy transition storms.
Summer: The Humidity Factor
July is our peak. The average high hits 85°F, but the humidity is what actually defines the weather in Hazel Crest during the summer. We have a "comfort index" that often drops because of the moisture in the air. June is actually our wettest month, averaging over 4 inches of rain. It’s not just rain, though—it’s those sudden, heavy thunderstorms that pop up around 4:00 PM and flood the low-lying intersections before vanishing.
Why the "Wind Factor" is Actually Rising
You might have noticed that the storms feel different lately. They do.
Recent climate risk reports, including those from First Street, indicate that maximum wind speeds in the Hazel Crest area are higher now than they were three decades ago. It’s not your imagination. We are seeing more frequent severe thunderstorm warnings. In fact, over the last year, the area has been under severe weather warnings dozens of times.
I remember the 1990 storm—though many younger residents won't. That was a massive event with 100 mph gusts nearby. While that’s rare, the "minor wind factor" risk is a real thing for 100% of homes here now. Trees are older, the infrastructure is settled, and a 60 mph gust can do way more damage today than it did in the 80s.

Surprising Facts About Our Sky
Did you know August is actually our clearest month? While July is hotter, August gives us clear or partly cloudy skies about 67% of the time. It’s the best time to be outside.
- Sunshine Hours: We get about 2,516 hours of sun a year.
- The Big Freeze: Our coldest day historically lands around January 29th.
- The Heat Peak: July 19th is statistically the hottest day of the year for us.
Flooding: The Moderate Risk Nobody Likes
Hazel Crest has a moderate flood risk score. Specifically, a score of 41 out of 100 according to Augurisk. We aren't in a "100-year" flood zone for the most part, but the "500-year" risk is there. This basically means that during those massive June downpours, the drainage systems in certain neighborhoods can get overwhelmed. If you're looking at property near the creek areas, it’s something you actually have to keep an eye on.
How to Actually Prepare for Hazel Crest Weather
Kinda seems obvious, right? Buy a coat. But it’s more than that.
If you live here, you need to understand the "Crest Cycle."
- The November Audit: Check your sump pump. Since we get a lot of late-winter melt and spring rain, a failed pump in March is a nightmare.
- The Tire Trap: When the temperature drops from 50°F to 10°F in one night (which happens every November), your tire pressure will tank. Don’t wait for the light to come on.
- Humidity Management: Invest in a good dehumidifier for the basement. Between the June rains and the July humidity, mold loves Hazel Crest basements.
The weather in Hazel Crest is a beast, but it’s a predictable one if you pay attention to the patterns instead of just the daily forecast. We live in a place where you can experience three seasons in a single commute. It’s exhausting, sure, but it also makes those perfect 72-degree September days feel like a genuine gift.
Your Next Steps for Local Readiness
To stay ahead of the curve, you should transition your home maintenance based on the specific month-by-month risks.
- Immediately: Check the seal on your windows. With January wind speeds averaging 18 mph, a small draft will spike your heating bill by 15% this month.
- By March: Clear your gutters. Hazel Crest's heaviest rain comes in the spring and early summer; blocked gutters are the primary cause of the "moderate" flood damage seen in local ranch homes.
- By June: Trim any overhanging tree limbs. Given the rising "Wind Factor" and the history of 60 mph gusts in the village, weak branches are a liability to your roof and power lines.
The weather here doesn't have to be a surprise if you respect the data. Keep an eye on the barometer, keep a shovel in the trunk until at least tax day, and you'll be just fine.
