Honestly, if you're looking at a weather app for Freeport, you're only getting half the story. Living on the South Shore of Long Island means the Atlantic Ocean is basically your unpredictable roommate. It’s not just about "sunny" or "cloudy." It’s about the salt air, the "Nautical Mile" breeze, and how a 35-degree day feels like 15 when the wind kicks up off the water.
Right now, Freeport is tucked firmly into the winter grind. Today, Sunday, January 18, 2026, it’s a heavy 34°F with a "feels like" temp of 28°F. Humidity is sitting at a thick 95%, which is why that cold feels so damp and biting—the kind that gets into your bones. Northeast winds are coming in at 7 mph, and we’re looking at a 100% chance of snow during the day, switching to snow showers at night.
The Seasonal Reality Check
You’ve probably seen those charts showing "average" temperatures, but averages are boring. Let's talk about how the year actually feels on the ground.
January is the coldest month here, period. We usually see highs around 40°F and lows near 28°F, but today’s forecast is actually a bit chillier with a high of 35°F. Tomorrow, Monday, January 19, things dry out with some sun, but the temperature drops further to a high of 33°F and a low of 20°F. If you’re planning to be outside, the wind is going to jump to 18 mph from the west. That’s the Long Island winter specialty: bright sun that does absolutely nothing to keep you warm.
By Tuesday, we hit a real deep freeze. We're talking a high of only 23°F and a low of 17°F. You’ll want the heavy puffer coat, not the fashionable wool one.
Weather Freeport New York: Why the Water Changes Everything
Freeport isn't just another suburb; it's a canal village. This proximity to the water creates a microclimate that can be wildly different from even five miles north in Garden City or Hempstead.

The Summer Humidity Trap
July is the hottest month, with highs averaging 82°F, but the humidity can make it feel like you’re walking through warm soup. The "muggy" factor hits its peak in late summer. While tourists flock to the Nautical Mile for seafood and live music, locals know that August is when the chance of rain hits its highest point, around 10 days of precipitation.
Nor'easters and the Flood Factor
We have to talk about the elephant in the room: flooding.
Freeport has a high flood risk score of 52. Because of the sea-level rise and the way the canals are built, even a "mild" storm can push water over the bulkheads.
- Hurricane Sandy (2012) remains the benchmark for disaster here, with a storm surge that literally reshaped the coastline.
- December 2022 saw record flooding along the Western Great South Bay, with water reaching up to Sunrise Highway in some spots.
- Today's Reality: With 2026 seeing intensified climate hazards, the village is constantly working on mitigation. If you live south of Merrick Road, you don't just check the temperature; you check the tide charts.
What to Pack (The Non-Boring Version)
If you're visiting or just moved here, forget what the fashion blogs say about "New York style."
- Winter (Dec–Feb): You need waterproof, skid-proof boots. When the snow melts and then freezes over at night, the sidewalks become skating rinks. Layers are your best friend because the shops on Main Street will be blasting the heat, but the wind on the pier will be brutal.
- Spring (March–May): This is the most "temperamental" time. You could have a 60-degree afternoon followed by a surprise dusting of snow. Keep a raincoat in the car. Seriously.
- Summer (June–Aug): Lightweight fabrics only. July sees the most sunshine—about 10.1 hours a day—so sunscreen isn't optional if you're out on a boat.
- Fall (Sept–Nov): This is actually the best time to be in Freeport. September is clear and crisp, with the sky being clear about 62% of the time. It’s the sweet spot before the winter clouds move in for their 7-month stay.
The 2026 Forecast Trend
Looking at the 10-day outlook for late January, we’re seeing a lot of "partly sunny" days mixed with some serious cold. Wednesday, Jan 21, brings a slight warmup to 37°F, but it’s followed by a heavy snow storm on Monday, Jan 26, where the chance of precipitation jumps to 75%.
Actionable Next Steps:
If you're in the Freeport area this week, prioritize clearing your storm drains before the snow hits today, as the 95% humidity means any melting will be slow and slushy. For those living in the southern flood zones, keep an eye on the wind direction for Monday; that 18 mph western wind can sometimes push extra water into the back bays during high tide. If you're commuting, Tuesday's 23°F high means you should check your tire pressure now—cold snaps like this are notorious for triggering those dashboard sensors.
