Right now, if you step outside in Cleveland, you aren't just hitting a wall of cold—you're walking into a 17°F reality that feels much, much sharper. It's Sunday night, January 18, 2026, and the city is currently tucked under a heavy layer of clouds.
Honestly, that 17-degree reading on your phone is a bit of a lie.
Thanks to an 8 mph wind cutting in from the southwest, the Cleveland temperature right now actually feels more like 7°F. That’s the "feels like" factor that catches people off guard when they’re just running out to grab the mail or walking the dog around Public Square. It’s cold. It’s unmistakably Northeast Ohio in January. But what’s actually happening behind these numbers is a lot more interesting than just another winter night.
The 17-Degree Reality and the Coming Deep Freeze
We’ve had a weird month. Just a few weeks ago, the Great Lakes were seeing ice coverage drop significantly because of some bizarre temperature swings—we even had days touching the 50s and 60s earlier in January. But that "weather whiplash," as the local meteorologists at WKYC like to call it, has officially ended. The "polar plunge" has arrived.
The current 17°F is actually the start of a much more aggressive cooling trend. While today’s high managed to hit 21°F during a briefly sunny afternoon, we’re heading toward a low of 13°F tonight.

There’s a 10% chance of snow right now, but that’s going to ramp up. By late tonight and into tomorrow, those "snow showers" mentioned in the forecast are likely to become a more permanent fixture. We’re looking at a 25% chance of flakes by morning.
What Most People Get Wrong About Cleveland Winters
People think Cleveland is just a constant state of "frozen" from November to March. That's not really true. If you look at the historical data from sources like WeatherSpark, the average high for mid-January is usually around 33°F. Being at 17°F right now means we are nearly 15 degrees below the seasonal norm.
This isn't just a "chilly" night; it's a legitimate cold snap.
Why the Wind Direction Matters
You've probably noticed the wind is coming from the southwest at 8 mph. In Cleveland, that southwest flow is often a bit of a reprieve compared to the dreaded "North Wind" that drags moisture across Lake Erie. However, because the lake ice coverage plummeted to under 3% recently (as reported on January 13), there is a lot of open water out there.

Open water + freezing air = lake effect machine.
When the lake isn't frozen, it acts like a giant humidifier. The cold air picks up that moisture and dumps it as snow on the East Side. So, while it's just "cloudy" right now, that open water is the reason the humidity is sitting at 64% even in the dead of winter. It makes the air feel "heavy" and "wet," which is why 17°F in Cleveland often feels colder than 17°F in a dry climate like Denver.
Surviving the 7-Degree "Feels Like" Temperature
Since it feels like 7°F out there, you have to worry about more than just a heavy coat. Local experts at Signal Cleveland have been sounding the alarm today about frozen pipes. When the actual temperature stays below 20°F for extended periods—which is exactly what we’re seeing tonight—the risk of your plumbing giving out goes up exponentially.
Basically, if you haven't opened your cabinet doors under the sink to let the warm house air circulate, you might want to do that before you go to bed.

What to expect tomorrow
Monday is looking even more brutal. While tonight is 17°F, the wind is expected to pick up to 17 mph tomorrow. We’re moving into a stretch where wind chills could drop between -10°F and -20°F. If you’re commuting into downtown or heading toward University Circle tomorrow morning, "bundle up" doesn't quite cover it. You're looking at a high of only 21°F again, but with much more aggressive wind.
Actionable Steps for the Cleveland Chill
The Cleveland temperature right now is a warning shot. Here is what you should actually do tonight:
- Drip the Faucets: If your kitchen sink is on an outside wall, let a tiny trickle of water run. It keeps the water moving so it won't freeze.
- Check the Pets: At 17°F (and 7°F wind chill), paws can freeze quickly. Limit outdoor time to strictly "business" only.
- Warming Centers: If your heat is struggling, the city is activating warming centers. Places like the Summit Lake Community Center in nearby Akron are already opening up for overnight shelter starting tonight, January 18.
- Car Prep: If you haven't started your car in a few days, the battery might struggle tomorrow morning. Give it a quick crank tonight to make sure it’s still holding a charge.
Cleveland weather is basically a sport. We’re currently in the middle of a cold-weather winning streak that doesn't look like it's breaking until at least next Friday. Stay warm, keep the cabinets open, and maybe keep a shovel near the door—those 25% snow chances usually have a way of turning into a few inches of lake-effect surprise by sunrise.
