So, you’re looking at the sky in Suffern and wondering if you should grab the heavy boots or if those sneakers will survive the walk to the train station. Honestly, Suffern weather is a bit of a local legend for being unpredictable.

The Real Deal on Weather Suffern NY Hourly Today
If you're checking the weather Suffern NY hourly for Sunday, January 18, 2026, here is the breakdown of what's actually happening on the ground.
Most people see "snow" on a forecast and assume a blizzard. Kinda dramatic, right? Today isn't a blizzard. It’s more of a persistent, annoying snow. The current conditions show a 74% chance of precipitation, specifically light snow. The wind is barely moving—just 1 mph from the southeast. It's quiet. Almost too quiet.
What to Expect Through the Afternoon
As we move through the day, that high is only hitting 32°F. Basically, we're hovering right at the freezing mark. That's the danger zone for commuters and anyone walking near Lafayette Ave. When the temp sits exactly at 32°F, the snow starts to get heavy and wet.
- The daytime snow chance jumps up to 85%.
- Expect the wind to pick up slightly to 5 mph from the northeast.
- The UV index is a flat 0, so don't worry about the sun; you won't see it.
The northeast wind is the one to watch. In our part of the Hudson Valley, a northeast wind usually means that cold air is being wedged against the Ramapo Mountains. This often keeps us a few degrees cooler than the city, which is why you might see snow here while your friends in Manhattan are just dealing with a cold rain.
Tonight’s Shift
Once the sun goes down (not that we’ll see it), things "warm up" to a low of 20°F. Wait, that’s not warming up. That's a 12-degree drop from the daytime high. The precipitation chance drops to 40%, and the condition shifts from active snow to just "cloudy."
Why Suffern Weather is Different from the Rest of Rockland
If you've lived here long enough, you know that Suffern is in a weird spot. We're right at the foot of the Ramapo Mountains. Geographically, this creates a microclimate.
According to data from the NYS Mesonet and local climate studies, the "Ramapo Pass" acts like a funnel for cold air. While places like Nyack might stay a bit more tempered by the Hudson River, Suffern gets that raw mountain air. This is why the weather Suffern NY hourly reports can sometimes look completely different from a general "New York" forecast.
Honestly, the mountain effect means we often get "trapped" clouds. That’s why our humidity stays so high (96% today!). The moisture gets stuck in the valley, creating that misty, snowy grayness that defines a Suffern winter.
Common Misconceptions About Suffern Winters
A lot of people think that because we're close to Jersey, we get Jersey weather. Not really.

- The "Jersey Shore" Myth: People think if it's raining in Mahwah, it's raining in Suffern. Often, the elevation change just over the border is enough to turn that rain into sleet or snow.
- The Humidity Factor: Most think high humidity is a summer problem. In Suffern, winter humidity is a beast. It makes 29°F feel like 15°F because the moisture in the air pulls heat away from your body faster.
- The Wind Direction: A southeast wind (which we have right now at 1 mph) usually brings in moisture. If that wind swings to the north, expect the temperature to tank fast.
Actionable Tips for Navigating Today
Since you're looking at a weather Suffern NY hourly update, you probably have somewhere to be. Here is the move:
Treat the roads like they're iced. Even if it’s just "light snow," that 32°F high means melting and re-freezing is happening constantly. Black ice on the bridge over the Thruway is a classic Suffern trap.
Dress for the damp, not just the cold. Layers are fine, but you need a waterproof outer shell today. With 96% humidity and snow, a wool coat will just soak up the water and get heavy. Go with something that sheds the wetness.

Watch the 4:00 PM transition. That’s usually when the daytime "slush" starts to turn into nighttime "ice" as the temp begins its slide toward 20°F. If you can be off the roads by then, do it.
Basically, today is a day for staying inside at a local coffee shop or making sure your shovel is by the door. It's not a "snow day" in the sense of a total shutdown, but it's a "be careful out there" kind of day. The light snow will likely linger, and that northeast wind will keep things feeling crisp and raw. Stay warm, Suffern.
