Right now, if you're standing near the brink of the Horseshoe Falls, your phone is probably telling you it's 20°F. It’s cold. Bracingly cold. But honestly, the "real" temperature at the falls is a bit of a lie.
Because of the massive volume of water crashing down, there’s this constant, freezing mist hanging in the air. On a night like tonight, January 18, 2026, with the humidity sitting at a heavy 79%, that mist doesn't just feel damp—it feels like a physical weight.

Most people check the weather, see a number like 20°F, and think a standard winter coat will do. It won't. You've got light snow showers moving through right now, and while the wind is technically a gentle 2 mph from the southwest, the microclimate created by the river makes it feel significantly sharper.
The Current Temp Niagara Falls Reality Check
The gap between the "official" temperature and what you actually feel on your skin is huge here. Today’s high only reached 22°F, and we’re looking at a low of 18°F tonight.
It’s tempting to think that a few degrees don't matter much. But at the Falls, they do. When the air temperature is 20°F and the water temperature in the Upper Niagara River is hovering around 33°F, you’re dealing with a massive thermal exchange. The water is actually "warmer" than the air, but the spray it kicks up is what gets you.
That spray hits your jacket and turns to a glaze of ice in seconds. Basically, you aren't just battling the cold; you're battling a self-generating ice machine.

Why the "Frozen Falls" is a Bit of a Myth
You’ve probably seen those viral photos of the falls looking completely frozen.
I hate to break it to you, but they almost never actually freeze solid. The sheer force of the water—roughly 3,160 tons flowing over every second—is too much for it to stop. What you're seeing in those photos is an "ice bridge."
The mist freezes onto everything nearby. It builds up on the rocks, the railings, and even the surface of the river, creating a thick white crust that looks like a glacier. Underneath that, the water is still roaring. On a night like this, with the 19% chance of snow currently manifesting as light flurries, that ice bridge is slowly thickening.
What to Expect if You're Heading Out Right Now
If you’re brave enough to walk the Niagara Parkway tonight, here’s the ground truth:
- Visibility: It’s a bit hazy. The snow is light, but the "light showers snow" condition reported means the air is thick.
- Underfoot: Treacherous. Even though the wind is low (2 mph), the mist from earlier today has likely frozen into "black ice" on the sidewalks.
- The Mood: Surprisingly quiet. Winter is the only time you can actually hear the roar of the water without the chatter of ten thousand tourists.
Dressing for a 20°F Mist Zone
Most people dress for the cold. You need to dress for a cold shower.

Skip the wool overcoat. You'll look great in photos for five minutes, then you'll be soaked and miserable. You need a waterproof shell. Honestly, a high-quality ski jacket or even a heavy raincoat over a puffer vest is the pro move here.
Also, your phone battery is going to die. Fast. Lithium-ion batteries hate this 20°F weather. If you're out taking photos of the illumination—which looks incredible against the snow, by the way—keep your phone in an internal pocket against your body heat when you aren't using it.
Survival Gear for the Parkway
- Waterproof boots: Not just warm ones. They need to be waterproof.
- Cleats/Grips: Those $20 slip-on ice spikes for your shoes are worth their weight in gold at the Table Rock viewing area.
- Extra Socks: Carry a pair in your bag. Trust me.
Looking Ahead: The Rest of the Week
Tomorrow, Monday, January 19, things get a bit more intense. We're looking at a high of 23°F but with a much lower low of 10°F.
The real kicker is the wind. Today we've been lucky with a 2 mph breeze, but tomorrow the wind is expected to kick up to 20 mph from the southwest. That’s going to drop the wind chill into the negatives. If you think the current temp Niagara Falls feels biting now, tomorrow will be a whole different animal.
By Tuesday, we're expecting the high to stay around 21°F with a continued 35% chance of snow. It’s a classic Great Lakes winter pattern. The moisture from Lake Erie feeds these persistent snow showers, and the Niagara gorge just funnels that cold air right at you.
Actionable Advice for Visitors
If you're in town tonight or arriving tomorrow, don't just stay in your hotel room. The winter illumination of the falls is spectacular, and the crowds are non-existent.
Pro Tip: Head to the tunnels at Journey Behind the Falls. It’s one of the few places where you can see the power of the water while being shielded from the wind. Plus, the rock walls stay at a relatively "warm" constant temperature compared to the 20°F air outside.
Just remember: the mist is the boss. Respect the spray, wear your layers, and keep your camera dry. You’ll get shots that the summer crowds will never see.
Next Steps: Check the local transit alerts if you're using the WEGO bus system, as snow squalls can sometimes cause minor delays near the falls. If you're driving, ensure your windshield washer fluid is rated for sub-zero temperatures—the spray from the road and the falls will freeze on your glass almost instantly.
