So, you're looking at a map of Western New York and figuring out if you need a parka or a polo shirt for a trip to Lewiston. Honestly, if you just glance at the "Buffalo area" forecast, you’re probably going to get it wrong. Most people lump Lewiston in with the blizzard-prone chaos of South Buffalo, but the reality is way more nuanced.
Lewiston is a bit of a geographic rebel. Nestled right up against the Niagara River and sitting below the towering Niagara Escarpment, this village has its own rules. Right now, on this Sunday, January 18, 2026, it’s a classic winter scene: 21°F and mostly cloudy. It feels more like 12°F thanks to a 7 mph breeze coming off the west. There’s a tiny 11% chance of snow today, but if you look at the next few days, the "lake effect" machine is starting to hum.
The Escarpment Magic: Why Lewiston Isn't a Snow Globe (Usually)
Here is the thing nobody talks about: the "Lewiston Banana Belt." Locals call it that because, believe it or not, it’s often several degrees warmer here than in the surrounding highlands.
The Niagara Escarpment acts like a massive stone wall. When those brutal lake-effect snow bands roll off Lake Erie—the ones that bury Buffalo under six feet of powder—they often skip right over Lewiston. The escarpment creates a weird air current where warm air from Lake Ontario gets trapped or forced down, keeping the frost at bay for a few extra weeks in the fall.

Actually, the science is kinda cool. The Niagara Escarpment AVA (American Viticultural Area) exists because this microclimate is so reliable. You’ve got a growing season that stretches over 205 days. That’s why you see so many world-class wineries in a place that people think is a frozen tundra.
What to Expect Right Now
If you’re stepping outside today, it’s crisp. We’re looking at a high of 22°F and a low of 18°F tonight. There’s a 40% chance of snow showers during the day, so don't be shocked if you see some flurries while walking down Center Street.
Tomorrow, Monday, January 19, things get a bit more "New York." The temperature stays around 23°F, but the wind picks up to 22 mph from the southwest. That’s going to make that 35% chance of snow feel a lot more aggressive.

The Seasonal Reality Check
Let's talk about the rest of the year, because Lewiston weather is a total chameleon.
- Spring: It’s a slow burn. March is usually a muddy mess around 32°F to 42°F, but by May, the Artpark trails are gorgeous, and you’re hitting the high 60s.
- Summer: This is the sweet spot. July averages a high of 80°F. It’s warm, sure, but the river breeze keeps it from feeling like a swamp. Most days are clear and perfect for the Outdoor Music Series.
- Fall: October is arguably the best time. The escarpment turns into a wall of fire with the changing leaves, and the temps hover in the high 50s. It's sweater weather, but without the biting wind of November.
- Winter: It's freezing. Let's be real. January and February rarely see highs above 32°F.
What Most People Miss About the Wind
Basically, the wind is the real boss in Lewiston. Because the village sits on the river, the air can tunnel through the gorge. Even on a sunny day, that wind off the water can make a 50-degree afternoon feel like 40. You’ve always got to have a layer ready.
Looking ahead at the 10-day forecast, we’re seeing a dip. By next Sunday, January 25, the high is only going to be 10°F. Yeah, you read that right. Ten. If you’re planning to head to the Niagara Falls area then, bring the heavy-duty gear.

Actionable Tips for Navigating Lewiston Weather
If you’re living here or just visiting, stop trusting the generic "Buffalo" weather app. Here is how you actually prep:
- The Two-Layer Rule: Even in July, the temperature drops fast once the sun goes down over the river. Always have a light jacket in the car.
- Watch the Southwest Wind: In the winter, a southwest wind (like we’re seeing tomorrow at 22 mph) is the one that brings the chill. If the wind is from the North or East, it's usually much calmer in the village.
- Traction Matters: Because of the moisture from the river and the Falls nearby, "black ice" is a real thing on the hills leading up the escarpment.
- Summer Planning: If you're hitting Artpark, check the humidity. July can get "muggy" about 36% of the time, which makes those outdoor concerts feel a lot hotter than the thermometer says.
Lewiston weather is basically a constant tug-of-war between the Great Lakes and the Escarpment. It’s unpredictable, occasionally brutal, but mostly way more pleasant than its neighbors to the south. Just keep an eye on those wind speeds and enjoy the fact that you aren't currently shoveling seven feet of snow.
