If you’re driving down Route 408 toward the village, you might think you’ve got the weather for Nunda NY figured out based on what’s happening in Rochester or Geneseo.
You’d be wrong.

Nunda is a weird little pocket. It’s tucked away in Livingston County, sitting right on the edge of the Genesee Valley and basically serving as the unofficial gateway to Letchworth State Park. Because of that topography—the way the land dips and rises near the "Grand Canyon of the East"—the weather here behaves with a mind of its own. One minute you’re looking at a crisp autumn afternoon, and the next, a wall of lake-effect snow has drifted over from Lake Erie, decided it likes the look of the valley, and parked itself right over the Nunda Family Pharmacy.
Honestly, it's the kind of place where you keep an ice scraper in your car until June. Just in case.
Understanding the "Nunda Gap" in Weather for Nunda NY
Most folks check their phones and see a generic forecast for "Western New York." But Nunda sits at an elevation of roughly 1,300 feet, which is significantly higher than the lake plains to the north. This elevation jump is critical. It means that while Rochester might be getting a chilly rain, Nunda is often seeing heavy, wet slush or straight-up snow.
The data doesn't lie about how cold it gets here.
In the dead of winter—usually late January—the average low drops to about 17°F or 18°F. That sounds manageable until you factor in the wind. The valley acts like a funnel. You’ll get these biting western winds that make 20 degrees feel like 5. January is officially the coldest month, but February actually tends to bring the most snow, averaging over 6 inches for the month. But those are just "averages." In reality, a single lake-effect event can dump 10 inches on North Street while the sun is shining ten miles away in Mount Morris.
The Summer Sweet Spot
If you're planning a trip to Triple Creek Golf Club or heading into the park, you’re looking for that July window. It’s the hottest month, sure, but "hot" in Nunda is different than "hot" in NYC. You’re looking at average highs of 79°F. It’s rarely oppressive. You might hit 88°F on a particularly nasty day, but the humidity usually breaks at night, dropping things back down to a comfortable 61°F.
It's perfect sleeping weather. No AC required, just a box fan in the window and the sound of the crickets.
Seasonal Breakdowns: What to Actually Expect
Let’s be real: spring in Nunda isn't really spring. It's "Mud Season."
- March and April: This is the transition zone. You’ll see a mix of rain and snow on about 7 to 8 days each month. The ground is thawing, the creek is rising, and the hiking trails in Letchworth are basically soup. If you’re visiting now, bring waterproof boots.
- May to June: This is when the village actually wakes up. The chance of a "wet day" (at least 0.04 inches of rain) peaks in June at about 39%. It's green, it's lush, and the lilacs are everywhere.
- September to October: This is the "Golden Hour" for the region. The weather for Nunda NY in September is arguably the best in the state. Highs stay around 70°F, the air gets dry, and the foliage starts to turn that deep burnt orange.
- November: The sky turns gray. Statistically, cloud cover jumps to over 70% as we head into December. It’s the "Big Dark" before the snow starts to stick.
The humidity here is a constant factor you won't see on every weather app. Because of the proximity to the Finger Lakes and the Genesee River, the air often feels "heavy." Even in the winter, the humidity can hover near 80%, which is why the cold feels like it’s "seeping into your bones" rather than just hitting your skin.
Historical Weirdness and Flooding
Nunda has had its share of drama. Because the Keshequa Creek runs through the area, flash flooding is the primary concern when the weather for Nunda NY takes a turn. We saw this historically across the region in 2006 and 2011. When you get a rapid snowmelt in March combined with a heavy spring rain, that water has nowhere to go but down into the valley.
The record highs and lows for the area are also pretty wild. While the average high is 79°F, we've seen spikes into the mid-90s. Conversely, in the winter of 1994, temperatures in the surrounding southern tier dropped well below -20°F.
Survival Tips for the Nunda Climate
If you're moving here or just passing through, don't trust a 24-hour forecast blindly.
First off, dress in layers. It's a cliché for a reason. You can start a July morning at 55°F and be sweating in 80°F heat by 2 PM. Second, if you're driving in the winter, keep a bag of sand or cat litter in the trunk. The hills around Nunda—especially if you're heading south toward Dalton—can get incredibly slick, and the local plow crews are good, but they can't be everywhere at once.
Lastly, watch the wind. If the forecast says 15 mph winds, expect 25 mph gusts in the open fields outside the village.
To stay ahead of the weather for Nunda NY, you should check the local radar specifically for "lake-effect streamers" coming off Lake Erie. These narrow bands of snow can miss the neighboring towns entirely but bury Nunda in a matter of hours. If you see a band forming on the radar that stretches from Buffalo straight toward Livingston County, it’s time to head home and get the shovel ready.
Before you head out to Letchworth or start your commute, take a quick look at the Dansville Municipal Airport (KDSV) station data, as it’s the closest reliable sensor for our specific microclimate.
