Honestly, if you’ve lived on the island for more than a week, you know the drill. You check the 10 day weather forecast long island new york on a Monday, plan a beach day or a commute for the following Thursday, and by Wednesday night, the entire thing has flipped on its head. It's basically the price we pay for living on a giant sandbar stuck out in the Atlantic.
The current situation is no different. Right now, we’re staring down a stretch of January that looks like a classic tug-of-war between the ocean and the Arctic.
The Current State of the 10 day weather forecast long island new york
As of today, Thursday, January 15, things are actually looking pretty bright, even if they’re crisp. We’re sitting at a high of 44°F with plenty of sun. But don't get used to it. The wind is coming out of the west at about 13 mph, which is just enough to remind you that it’s definitely still winter.
If you're looking at the immediate window, Friday stays relatively dry with a high of 35°F, but the real shift happens over the weekend. Saturday, January 17, is looking messy. We're talking a rain-snow mix with a 65% chance of precipitation. With a high of 40°F, it’s that annoying kind of slushy weather that makes the LIE a nightmare.

Sunday brings a bit of light snow, though only a 20% chance, and then we hit a massive temperature cliff. By Tuesday, January 20, the high is projected to be just 21°F. That's a "stay inside and order a bagel" kind of day.
Why Long Island Weather is So Hard to Predict
Microclimates. That’s the short answer. You can have a full-blown blizzard in Stony Brook while people in Long Beach are just getting hit with a cold mist.
Because we’re surrounded by water, the ocean acts like a giant radiator. In the winter, the relatively warmer sea water often keeps the South Shore just a few degrees above freezing, turning what would be a foot of snow into a cold, depressing rain. This is why the 10 day weather forecast long island new york often feels like a guessing game for meteorologists. They’re trying to figure out exactly where that "rain-snow line" is going to park itself.

What to Expect Over the Next Week
Let's break down the vibe for the coming days based on the latest data.
- The Big Dip: Monday and Tuesday are going to be the coldest days of this stretch. We’re looking at lows around 15°F. If you haven't dripped your pipes or checked your antifreeze, now is the time.
- The Mid-Week Rebound: Wednesday, January 21, sees us creeping back up to 32°F. It’s still freezing, obviously, but compared to 21 degrees, it’ll feel like a heatwave.
- The Late Week Flurries: Towards the end of the 10-day window, specifically Saturday, January 24, we’re seeing another 45% chance of light snow. It’s not looking like a "bread and milk" emergency yet, but it’s worth keeping an eye on if you have travel plans.
The La Niña Factor
This year is a bit weird because we’re dealing with a weak La Niña. According to Jay Engle at the National Weather Service, weak La Niña years are notoriously unpredictable. Usually, it means we get near or slightly below-average snowfall, but the totals can swing wildly. One big Nor'easter can dump 15 inches and blow the whole average out of the water.
Local experts are split. Some, like the folks over at NY Metro Weather, are leaning toward a snowier-than-usual season, while others are betting on the warmer Atlantic water keeping us mostly wet and slushy.

Survival Tips for the Long Island Winter
Look, the 10 day weather forecast long island new york is a tool, not a promise.
If you’re commuting into the city, pay way more attention to the wind speeds than the temperature. A 30-degree day with a 5 mph wind is fine. A 30-degree day with 17 mph gusts out of the southwest (which we're expecting on the 21st) will cut right through your coat.
Also, salt your driveway before the Saturday mix hits. Once that rain-snow combo freezes over on Sunday night when the temp drops to 23°F, your driveway will turn into an ice rink.
Basically, keep the scraper in the car and the heavy boots by the door. We’ve got at least another two months of this "is it snowing or just raining?" drama to get through.
Check your tire pressure tonight. As the temperature drops from 44 degrees today to the low 20s next week, your "low pressure" light is almost guaranteed to pop on. Save yourself the stress and top them off now while it's still relatively mild outside.
