Checking the 10 day weather monticello ny is basically a rite of passage if you’re planning a trip to the Sullivan Catskills this January. Honestly, the weather here is a bit of a moody teenager. One minute you’re looking at a manageable 34°F day with some light cloud cover, and the next, a west wind is kicking up at 16 mph, making the "RealFeel" drop into the single digits. If you’re heading to Resorts World or planning to hit the tubing runs at Holiday Mountain, you’ve gotta look past the basic high/low numbers.
People often assume "cold is cold," but in Monticello, the humidity and wind direction change the game. We are currently looking at a stretch where the mercury is struggling to stay above freezing. For today, Thursday, January 15, we're seeing a high of 34°F, but don’t let that fool you. By tonight, it's plummeting to 11°F. That’s a 23-degree drop in just a few hours.
The Reality of the 10 Day Weather Monticello NY Forecast
When you dig into the data for the next week and a half, there’s a clear pattern of "clipper" systems moving through. Friday, January 16, looks even colder with a high of only 25°F. You’ll want the heavy parka for that one. Saturday is the day to watch; we're expecting about a 40% chance of snow with a high of 33°F. It’s that wet, heavy snow that’s great for sledding but a total pain to shovel.
The middle of next week is where it gets interesting. Tuesday, January 20, is forecasted to be a "high" of 14°F. Yes, 14 degrees. That is the kind of cold that hurts your face.

The wind is the real culprit here. Coming off the mountains, a 13-15 mph wind turns a 20-degree day into something much more biting. If you're driving up Route 17 (the Quickway), remember that the bridges and overpasses around Monticello freeze way faster than the road. The black ice on the bridge over the Neversink River is notorious.
What This Means for Your Plans
If you're coming for the outdoor stuff, it's actually not bad news. Holiday Mountain has been running their snowmaking systems, and these consistent sub-freezing night temperatures are exactly what they need. They recently upgraded their lighting, so night skiing is a big thing now.

But if you’re not a fan of the frost, the Kartrite Indoor Waterpark is sitting pretty at a constant 84°F. It’s a weird feeling to look through the glass at a blizzard while you’re in a swimsuit, but it works.
- Layering is a non-negotiable. We're talking wool socks and thermal bases.
- Watch the Saturday snow. A 40% chance might sound low, but in the Catskills, that often turns into a localized "snow squall" that can drop two inches in an hour.
- Vehicle Prep. Check your tire pressure. These 10-degree nights will make your "low tire" light pop on immediately.
Understanding the Microclimate
Monticello sits at an elevation of about 1,500 feet. That's significantly higher than New York City or even Middletown. Because of this, it’s usually 5 to 10 degrees colder here than it is just 40 minutes south.
- Cloud Cover: January in Monticello is overcast about 57% of the time. Don't expect a lot of Vitamin D this week.
- Visibility: With the humidity hovering around 90%, morning fog is a real thing, especially near the local lakes.
- Wind Chill: Monday night, January 19, the low is 6°F. With the southwest wind, it’s going to feel like -10°F.
Driving conditions for the 10 day weather monticello ny window are generally "clear and dry" right now, according to the NYS Thruway Authority, but that Saturday snow could change things for the weekend travelers. Sullivan County DPW is usually pretty fast with the salt trucks, but Route 17 can get greasy fast when the wind starts blowing snow across the lanes.
Actionable Tips for the Next 10 Days
Don't just look at the sun icon on your phone app. Actually look at the wind speed. Anything over 10 mph in 20-degree weather means you need a windbreaker layer.
If you’re staying at a local Airbnb, ask if they have a backup generator. Sullivan County is beautiful, but a heavy ice-snow mix can occasionally knock out power lines in the more wooded areas.

Finally, keep an eye on the Saturday, January 24th forecast. Long-range models are showing a 75% chance of snow with a high of 38°F. That’s "slush weather." It’s messy, it’s slippery, and it’s the kind of day where you’re better off staying inside the casino or the waterpark.
Next Steps:
Before you head out, check the 511NY app for real-time traffic cameras on Route 17 and I-87. If the Saturday snow hits 40% or higher, aim to arrive in Monticello before 2:00 PM to avoid the worst of the visibility issues.
