Living in Lindenhurst means you're basically in a constant relationship with the Great South Bay. Honestly, if you grew up south of Montauk Highway, your internal compass isn't set to North or South; it’s set to "How high is the tide?"
Right now, looking at the data for Saturday, January 17, 2026, it's typical January messiness. We’re sitting at 39°F, but with a southwest wind kicking at 13 mph, it actually feels like 31°F. There’s a 90% chance of light rain today. It’s that raw, damp Long Island cold that just sort of sinks into your bones.

The Reality of Weather in Lindenhurst NY
Lindenhurst isn't just "New York weather." It’s coastal weather. That means while someone in Albany is dealing with dry snow, we’re often dealing with "wintery mixes"—that slushy, annoying middle ground. Today, the high is hitting 42°F, which is actually slightly above the historical January average of 40°F.
But don't let the "warm" high fool you. Tonight, it drops to 34°F.
People think Lindenhurst is just about the beach in the summer. Kinda true, but the winter is where the real local knowledge comes in. You’ve gotta know which streets turn into ponds. For instance, Venetian Blvd and Bay Place are famous for taking on water when the wind shifts the wrong way.
What the Next Few Days Look Like
If you're planning your week, keep the shovel and the umbrella close.
- Sunday, January 18: It’s looking like a rain and snow combo. High of 35°F, low of 25°F. There’s a 45% chance of snow both day and night.
- Monday, January 19: Mostly sunny but much colder. High of 34°F and a low of 20°F. Watch out for the wind; it’s going to be blowing at 22 mph from the west.
- Tuesday, January 20: This is the deep freeze. High of only 24°F and a low of 15°F.
Why the Great South Bay Changes Everything
The Bay is a giant heat sink. In the fall, it stays warm longer, keeping the "Lindy" air a bit milder than deeper parts of the island. But in January? It’s just a source of moisture and wind.
Historically, January is our windiest month, averaging around 18.1 mph. When you combine that with the 81% average humidity we see this time of year, you get that "wet cold." It’s why a 35-degree day in Lindenhurst feels way worse than a 20-degree day in Colorado.

The Flooding Factor
You can't talk about weather in Lindenhurst NY without talking about water.
About 45% of properties here have some level of flood risk over the next few decades. We aren't just talking about another Hurricane Sandy—which, by the way, impacted over 400 properties here. Even "minor" events can be a headache. On October 30, 2017, we saw a foot of water on South 8th Street just from a bad combination of rain and tides.
Today’s high tide in nearby Babylon is at 8:49 am, so if you’re near the canals, you’ve likely already seen the water creeping up the bulkheads.
Seasonal Survival Tips
Lindenhurst is beautiful, but it requires a specific kind of prep.
- Check the Tides: If you live south of Hoffman Ave, the tide chart is more important than the temperature.
- Layer for Wind: A heavy wool coat looks nice, but a windbreaker over a fleece is what actually works when you're walking near the marina.
- Bulkhead Maintenance: January is a great time to inspect your bulkheads for winter damage before the spring thaws and rains hit.
The rest of the month looks fairly consistent with this "cold and breezy" pattern. We're looking at highs in the 20s and 30s through the end of January, with various chances of snow on the 22nd and 26th.
Keep your salt buckets ready.
Actionable Insight: Since we’re expecting a drop to 15°F by Tuesday, now is the time to ensure your outdoor spigots are drained and your car’s antifreeze levels are checked. That kind of drop can catch your plumbing off guard if you're not ready.
