Honestly, if you've spent any time in Long Beach, you know the "City by the Sea" is a whole different beast in January compared to those July boardwalk days. Right now, it’s not exactly beach weather. Today, Sunday, January 18, 2026, we’re looking at a high of 36°F and a low dipping to 27°F. It’s basically that damp, salt-air cold that gets into your bones.
The big story for today is the light snow. We have a 54% chance during the day and it hangs around at 45% tonight. If you're out near the West End or grabbing coffee on West Park Ave, expect things to look a little dusty and grey. The wind is coming from the east at about 10 mph, which doesn't sound like much, but on a barrier island, that breeze carries a bite.
Long Beach NY Weather 10 Day Forecast: The Deep Freeze is Moving In
Kinda feels like winter just decided to show up all at once. Tomorrow, Monday, January 19, the snow clears out for a sunny day, but don't let the blue skies fool you. The high is only hitting 34°F, and the wind is going to be howling from the west at 20 mph. By Tuesday, we are looking at a bone-chilling high of just 24°F. That's a 10-degree drop in 24 hours.
If you're planning your week, here is the basic vibe for the Long Beach NY weather 10 day forecast:
The midweek stretch brings a bit of a "warm" up—if you can call 35°F on Wednesday warm. But it comes with a price: 24 mph winds coming from the southwest. It’s going to be one of those days where the ocean looks angry and the dunes are doing a lot of heavy lifting. Thursday and Friday settle back into the low 30s with partly sunny to mostly cloudy skies.
Then comes next Saturday, January 24. We’re looking at a messy rain and snow mix with a high of 33°F. It’s that classic Long Island slush that makes driving on the Loop Parkway a total nightmare.

Why the Ocean Temperature Matters Right Now
Most people think the ocean just stays "cold" in the winter, but the specifics actually dictate our local microclimate. Right now, the sea temperature is hovering around 42°F. That’s actually warmer than the air, which is why we often see "sea smoke" or extra-thick fog when those Arctic blasts hit the shore.
If you’re a local surfer—and yeah, the Long Beach crew is out there year-round—you’re basically living in a 5/4mm wetsuit with boots, gloves, and a hood. The wind chill today makes that 33°F air feel a lot more like 20°F.
Managing the Barrier Island Elements
Living on a strip of sand between the Atlantic and the Reynolds Channel means we have to deal with stuff the rest of Nassau County doesn't.
- Corrosion is real: This heavy humidity (92% right now) mixed with salt spray is a killer for cars parked outside. If you can, hit the car wash after the snow clears to get that salt off the undercarriage.
- Flooding risks: While there's no major storm surge in the immediate long beach ny weather 10 day forecast, the National Weather Service has been keeping an eye on minor tidal inundation. High tide today is the time to watch the bayside streets if you're in a low-lying area.
- The "Wind Tunnel" effect: Long Beach is a grid. Those north-south streets act like wind tunnels. With 20+ mph gusts expected Tuesday and Wednesday, make sure your trash cans are weighted down or tucked away.
What the End of January Looks Like
As we move toward the final days of the month, it doesn't get much better. Sunday, January 25 through Tuesday, January 27, the temperatures stay firmly in the 20s. Monday night is looking particularly brutal with a low of 15°F.
Basically, the island is entering a true deep freeze. If you're walking the boardwalk, stick to the daytime hours when the UV index hits 2—it's not much, but it's enough to make the sun feel slightly helpful.
Actionable Next Steps:
Keep an eye on the 24 mph gusts forecast for Wednesday, January 21, as this may impact bridge travel or loose outdoor furniture. Given the low of 15°F forecasted for next Monday, now is the time to ensure any outdoor pipes are properly insulated before the ground hardens.
