West Lafayette isn't exactly a tropical paradise in the middle of January. If you’re living here, you probably already know that. But honestly, the way people talk about the "Bermuda Triangle of Indiana" weather usually misses the nuance of what’s actually hitting the pavement at Purdue. Right now, it’s 22°F outside. It feels like 12°F. That ten-degree gap is the difference between a brisk walk to class and your face feeling like it’s being exfoliated by a frozen sandpaper sponge.
The west lafayette in weather forecast today shows a "high" of 22°F and a low of 11°F. It sounds manageable on paper. But with a 10 mph wind coming off the southwest, that "feels like" temperature is the only number that actually matters when you're standing at the corner of State Street and Grant.
The Reality of the "RealFeel" Gap
Most people look at a forecast and see 22 degrees and think, "Okay, heavy coat." But they ignore the southwest wind. In West Lafayette, the wind is a permanent resident. Because we’re surrounded by flat cornfields that act like a giant runway for Arctic air, a 10 mph wind has a way of cutting through even the most expensive parkas.
Tonight, the situation shifts. We’re looking at a 20% chance of snow showers. It’s not much—barely enough to cover the ground—but it’s coming on the heels of a 67% humidity level. That’s the "wet cold." It’s the kind of chill that sinks into your bones and stays there until you’ve had at least two cups of Greyhouse coffee.
- Current Temp: 22°F
- Wind: 10 mph from the Southwest
- Visibility: 10 miles (clear enough to see the Boilermaker Special coming, at least)
- UV Index: 0 (Don't worry about the sunscreen today)
Tomorrow is a Different Beast
If you think today is biting, Monday, January 19, is bringing a reality check. We’re looking at a high of only 12°F and a low of 7°F. The wind speed is jumping up to 19 mph from the west. When you combine 12 degrees with 19 mph winds, the wind chill is going to be brutal. There’s a Cold Weather Advisory in effect starting at 4:00 AM tomorrow. We’re talking wind chill values that could hit 19 below zero.
That's not "it's cold" weather. That's "exposed skin freezes in 30 minutes" weather.
Why the West Lafayette Microclimate is Weird
Purdue University’s airport (KLAF) usually records temperatures a few degrees different than what you might see in downtown Lafayette across the river. Why? Because the elevation at the airport is around 604 feet, and the open space allows for higher wind gusts.
Wednesday, January 21, is the outlier in the current west lafayette in weather forecast. We might actually hit 37°F. For a split second, it’ll feel like spring—relatively speaking. But don't get your hopes up. That "warmth" is coming with a 25% chance of rain and snow. It’s going to be slushy, messy, and generally unpleasant for anyone trying to navigate the hills of Chauncey.
What the 10-Day Outlook Tells Us
Looking further out, the pattern is basically a rollercoaster of "cold" and "colder."
- Tuesday: A slight recovery to 31°F. Mostly sunny.
- Friday: Back down to 14°F.
- The Weekend: Saturday and Sunday (Jan 24-25) are looking like a repeat of the deep freeze, with highs near 12°F and 19°F respectively.
If you’re planning on traveling or even just commuting across the Wabash, pay attention to the humidity and dew point. Right now, the humidity is 62%, which is high enough to keep the air feeling heavy. When that drops on Monday to 53%, the air is going to feel sharp and dry.
Navigating the Boilermaker Winter
Honestly, the biggest mistake people make with the west lafayette in weather forecast is assuming that "Sunny" means "Warm." Monday will be sunny, but it’ll be the coldest day of the week. The sun in an Indiana winter is often a liar. It reflects off the snow and makes everything look beautiful while the mercury stays firmly stuck in the basement.
If you're out and about, the southwest wind direction is your biggest enemy today. It's pushing that 10 mph breeze directly against anyone walking west toward the dorms or the Discovery Park District.

Actionable Advice for the Next 48 Hours
Stop looking at the high temperature. Start looking at the wind speed and the "night_time_condition." With a Cold Weather Advisory hitting tomorrow morning, tonight is the time to make sure your car's battery is in good shape and your tires aren't low on pressure. Cold air causes tire pressure to drop, and there's nothing worse than a "Low Tire" light when it's 7 degrees outside.
Layer up with a base that wicks moisture. The 67% humidity means if you sweat while walking, you’re going to freeze the moment you stop.
Keep an eye on Wednesday’s 25% chance of precipitation. It’s the highest chance of the week, and with temperatures hovering near 37°F, it’s the perfect recipe for black ice as the sun goes down and everything refreezes. Stay safe, stay warm, and remember that even in West Lafayette, spring is eventually coming—just not this week.
