Honestly, if you’re looking at the forecast for Port Byron, you’re probably seeing a lot of "cloudy" and "snow" and thinking it’s just another frozen wasteland in Central New York. You've seen the national news where Buffalo gets buried under six feet of snow while people are literally trapped in their cars. But here’s the thing: Port Byron isn't Buffalo. It’s got this weird, specific weather identity that’s part Finger Lakes chill and part Erie Canal dampness.
Right now, as of early Saturday morning, January 17, 2026, it’s 28°F outside. It feels more like 19°F because of a 12 mph wind coming from the south. It’s nighttime, it’s cloudy, and there’s a tiny bit of snow in the air—about a 16% chance. Basically, it’s a typical January night where you don’t want to be out longer than it takes to start the car.
The Reality of Weather for Port Byron NY
Most people think "Upstate NY" is just one big snow globe. It’s not. Port Byron sits in this interesting pocket. It’s about 25 miles west of Syracuse, which is famously one of the snowiest cities in America. But Port Byron often avoids the absolute worst of the lake-effect bands that hammer Syracuse or the Tug Hill Plateau.
Today, Saturday, we’re looking at a high of 38°F. That’s actually a bit of a "warm" spike for January. We’ve got snow showers during the day—a 45% chance—so the roads might get a little greasy. But by tonight, it’s supposed to clear up, dropping down to 24°F. That’s the classic New York trap. The snow melts a bit during the day, then freezes into a sheet of black ice the second the sun goes down.
What to Expect This Week
If you’re planning your week, keep the shovel handy but don't panic. Sunday is looking colder with a high of 24°F and some light snow. By Monday and Tuesday, the temperatures really start to slide. We’re talking highs of 25°F on Monday and a brutal 15°F on Tuesday.

Tuesday night is going to be the "stay inside and order pizza" kind of night, with a low of 10°F and 16 mph winds coming off the west. When the wind hits double digits in Port Byron, it cuts right through a cheap fleece. You need the heavy stuff.
Why the Finger Lakes Matter
The weather here is heavily dictated by the Finger Lakes microclimate. While places like Cayuga Lake and Owasco Lake aren't big enough to create the massive "Lake Effect" storms you see off Lake Ontario, they do moderate the temperature. In the summer, they keep things cooler. In the winter, they can actually keep the immediate area a couple of degrees warmer than the high-elevation spots like Moravia or Tully.
However, that humidity—currently sitting at 77%—is what makes the cold feel "wet." It’s a bone-chilling cold that lingers. It’s not like a dry cold in Colorado where 20°F feels refreshing. In Port Byron, 20°F feels like it’s trying to move into your house.
Driving and Survival Tips for the 13140
If you're new to the area or just passing through on the Thruway, there are a few things that'll save your life—or at least your bumper.
- The Half-Tank Rule: Never let your gas tank get below half. If you get stuck on Route 31 or the Thruway because of a sudden whiteout, you need that engine running for heat.
- Black Ice is Real: When the temp is 28°F like it is right now, and the road looks "wet," assume it’s ice. Especially on the bridges over the canal.
- Layers, Not Bulky Coats: Everyone buys one giant puffer jacket. Experts (and grandmas) will tell you that three thinner layers are better. A base layer to wick sweat, a middle layer for insulation, and a shell to block the wind.
- The "Clipper" Factor: Watch out for "clippers." These are fast-moving storms from Canada. They don't drop feet of snow, but they drop two inches of super-slick powder in twenty minutes.
The Long-Term Forecast: Is Winter Ending Early?
Historically, January is the coldest month here, with average lows around 19°F. Looking at the next ten days, we’re staying pretty much in that zone. We have a couple of "thaw" days where it hits the 30s, but then it plunges back into the teens.

Next weekend, January 24th and 25th, is looking particularly cold. We’re seeing highs of 20°F and 17°F respectively. Sunday night, the 25th, might even hit 1°F. That’s the kind of weather where you make sure your outdoor faucets are covered and your pets are nowhere near the door.
Actionable Next Steps for Port Byron Residents
- Check your Carbon Monoxide detectors. With the 10°F lows coming Tuesday, furnaces are going to be working overtime.
- Top off your windshield washer fluid. The salt spray on the roads this week will turn your windshield into an opaque mess in five miles. Make sure you have the "-20°F" rated stuff.
- Clear your tailpipe. If you do have to pull over in the snow, make sure the snow isn't blocking your exhaust. That’s how CO poisoning happens in cars.
- Watch the wind. Monday and Tuesday have winds up to 16 mph. If you have loose patio furniture or holiday decorations still out, they’re going to end up in your neighbor's yard.
Port Byron weather isn't just about the numbers; it's about the timing. A high of 38°F sounds great until you realize it’s followed by a 24°F freeze-up. Stay smart, keep the scraper in the car, and maybe treat yourself to some heavy-duty wool socks. You’re gonna need ‘em this Tuesday.
