Living in Irvington means you're basically at the mercy of the Hudson River. It's beautiful, sure. But if you’ve ever walked down Main Street toward the train station in February, you know that the "river breeze" is actually a bone-chilling wind tunnel that doesn't care about your expensive parka.
Weather Irvington New York is weirdly specific. You can be in White Plains and it’s a calm 45 degrees, but the moment you drop down the hill into the village, the humidity spikes and the wind picks up. It’s a microclimate. Honestly, it's the kind of place where you need a rain shell in your car at all times because the clouds just sort of "hang" over the Tappan Zee (or the Mario Cuomo Bridge, depending on how long you've lived here) before dumping on the village.
The Reality of the Seasons (Beyond the Postcards)
Summer in Irvington is gorgeous, but it's thick. July is the hottest month, with average highs hitting around 85°F. That sounds manageable until you add the 65% humidity coming off the water. It feels like walking through a warm, wet blanket. If you’re at Matthiessen Park, you’ll get that slight relief from the water, but by the time you hike back up toward Broadway, you’re sweating.

Winter is a different beast entirely.
January is officially the coldest month. We're talking average highs of 38°F and lows that dip to 25°F or lower. But those are just numbers. The real factor is the wind speed, which averages about 13 mph in the winter. Because Irvington is on a slope facing the river, that northern wind has plenty of room to pick up speed.
- Snowfall is unpredictable. One year we get a dusting; the next, a Nor'easter dumps 14 inches and shuts down the Metro-North.
- The "Hill" Factor. If you live in East Irvington, you might have four inches of snow while the waterfront just has slush.
- Ice. Because of the elevation changes, black ice on the steep side streets is a genuine hazard every February morning.
Why the Hudson River Dictates Your Weekend
The river acts as a massive thermal regulator. In the spring, the water is still freezing, which keeps the village a few degrees cooler than inland Westchester. You’ll see the daffodils blooming in Ardsley while Irvington is still looking a bit grey.

In the fall, the opposite happens. The water holds onto the summer heat. This actually extends the growing season for local gardens and keeps the foliage vibrant a little longer. If you’re planning a visit for the leaves, late October is usually the sweet spot.
When It Actually Rains (and Floods)
Irvington gets a lot of rain—about 50 inches a year. That’s more than the national average. July is actually the wettest month on paper, mostly due to those massive afternoon thunderstorms that roll across the river from Rockland County.

You’ve got to watch the drainage. Places like Sunnyside Brook and Barney Brook can swell fast. If the National Weather Service issues a flash flood warning for Westchester, Irvington residents—especially those near the bottom of the hills—start checking their sump pumps.
Practical Tips for Weathering Irvington
If you're moving here or just visiting for a day at Washington Irving’s Sunnyside, don't trust a generic "New York City" weather report. It won't be right.
- Layer like a pro. The temperature can swing 20 degrees between the waterfront and the top of the village.
- Check the tides. High tides on the Hudson combined with heavy rain can lead to localized flooding near the tracks.
- Windproof everything. Umbrellas are basically useless on Main Street when a storm is coming off the river; they'll just flip inside out. Get a good raincoat with a hood.
The best time to be here? Late September. The humidity breaks, the wind is a calm 7 mph, and the sky is clear about 63% of the time. It’s perfect.
Next Steps for Your Trip or Home Prep:
Check the specific "Point Forecast" for zip code 10533 rather than the general county outlook. If you are near the riverfront, keep an eye on the Piermont tide gauge, as it's the most accurate indicator for potential water rise in Irvington.
