If you’re checking the weather in Fallsburg NY because you’re planning a weekend getaway or thinking about moving to Sullivan County, you’ve probably seen the standard charts. They tell you it gets cold in January and warm in July. Groundbreaking, right? Honestly, those generic forecasts miss the nuances of living in the Catskills. This isn’t just "upstate weather"—it’s a specific atmospheric mix dictated by the Neversink River and the rolling hills that make this part of New York feel like a different world compared to the city.
The Reality of a Fallsburg Winter
Let's get real about winter. From December through March, Fallsburg essentially turns into a giant snow globe. But it’s not always the "pretty" kind. The cold season here lasts about 3.3 months, and the temperature typically hangs between 16°F and 31°F. If you're coming from New York City, you'll notice it's consistently 5 to 10 degrees colder here.
Why? Elevation and geography. Fallsburg sits at an average elevation that catches the moisture coming off the Great Lakes, resulting in what locals call "nuisance snow"—those constant 1- to 2-inch dustings that happen almost every other day. According to the NYS Mesonet station data at Sullivan County International Airport (KMSV), January is the absolute coldest month. You haven't truly experienced the weather in Fallsburg NY until you've felt a 15°F morning with a northwest wind whipping across an icy Neversink.
Spring: The "Mud Season"
Spring in Fallsburg is less of a blooming garden and more of a muddy marathon. It's short. Basically, April is a month of indecision. You might have a 60°F day on Monday where you're tempted to put away the parka, only to wake up to a freezing rain event on Wednesday.

The ground stays frozen deep into March, so when the April showers hit—averaging nearly 4 inches of rain—the water has nowhere to go. This is the peak time for the Neversink River to rise. If you’re hiking the Neversink Unique Area during this time, waterproof boots aren't optional; they're a survival tool.
Summers are the Reason People Come Here
There’s a reason the "Borscht Belt" hotels thrived in this area for decades. The summer weather in Fallsburg NY is nearly perfect. While the city is sweltering in 95°F humidity, Fallsburg stays in the sweet spot.
- July Highs: Usually top out at 79°F.
- Evening Lows: Drop to a crisp 59°F.
- Humidity: It’s "wet" (we get about 10 days of rain in June), but rarely that suffocating, stagnant heat.
The clearest skies of the year happen in August. If you're into stargazing, this is your window. The cloud cover drops to about 38%, making it one of the few places in the Northeast where you can actually see the Milky Way on a consistent basis.

Fall: The Sullivan County Showstopper
September and October are arguably the best months for anyone who isn't a fan of the heat or the snow. The humidity vanishes. The air gets that sharp, apple-crisp bite to it. Leaf-peeping peaks usually around the second or third week of October.
One thing most tourists miss about the weather in Fallsburg NY during autumn is the "valley fog." Because of the proximity to the river and the various lakes like Morningside or Pleasure Lake, the mornings are often thick with mist that burns off by 10:00 AM. It’s hauntingly beautiful, but it makes for some tricky driving on Route 42.
Extreme Weather and Microclimates
Fallsburg isn't immune to the big stuff. We've seen the impact of Hurricane Irene and Superstorm Sandy, which sent the Neversink over its banks and cut off local roads. Because we are nestled in the Catskills, we also deal with "micro-bursts"—isolated, intense wind events that can knock down power lines on one street while the next block is perfectly calm.

Actionable Tips for Navigating Fallsburg Weather
If you're visiting or staying, don't rely on the "New York" forecast you see on the national news. That's for Central Park. Here is how you actually prepare for the weather in Fallsburg NY:
- The 10-Degree Rule: Always assume it is 10 degrees colder in Fallsburg than it is in NYC or North Jersey. If you’re packing, bring one more layer than you think you need.
- Tire Check: From November to April, all-season tires are the bare minimum. If you live on a hill, you need dedicated snow tires. The salt trucks in Sullivan County are great, but the hills don't care.
- Summer Evenings: Even in the dead of July, you’ll want a light hoodie. Once the sun drops behind the mountains, the temperature plummets quickly.
- Flood Awareness: If you’re booking a rental near the river, check the historical flood maps on the FEMA website. The Neversink is beautiful but can be temperamental after a heavy spring melt.
- Download the Right App: Use an app that pulls specifically from the KMSV (Sullivan County International Airport) station for the most accurate local data.
Understanding the weather in Fallsburg NY means embracing the variability. It’s a place where you can go from a morning heater to an afternoon air conditioner in the span of six hours. But for those who love the distinct feel of four true seasons, there isn't a better spot in the Hudson Valley/Catskill region.
Check the local radar, pack your boots, and enjoy the mountain air. It’s better up here.
