You’ve heard the jokes. People call Montauk "The End." Geographically, they aren't wrong. When you stand at the edge of the Montauk Point Lighthouse, there is nothing but three thousand miles of churning Atlantic between you and Portugal.
But if you’re checking the weather forecast montauk new york before a weekend trip, you quickly realize the Atlantic doesn't just provide a view. It dictates the entire vibe.
Honestly, Montauk exists in a bubble. While the rest of Long Island might be sweating through a humid July afternoon, the "End" is often ten degrees cooler, wrapped in a blanket of sea fog that feels more like the Scottish Highlands than the Hamptons.
What’s Happening Right Now (January 17, 2026)
If you’re looking out the window today, Saturday, January 17, it’s looking pretty grey.
The current temperature is sitting at 39°F, but it doesn't feel like that. Thanks to a west wind blowing at 17 mph, the "feels like" temp is actually closer to 30°F. We’ve got some light rain falling right now, and the humidity is high—around 83%.
Basically, it’s raw.

Today’s high should hit 44°F before dipping to a low of 36°F tonight. The clouds aren't going anywhere. If you’re heading out, you’ll want more than a light jacket. That wind coming off the water has a way of cutting through denim like it’s paper.
The Week Ahead: A Mixed Bag of Slush
The weather forecast montauk new york for the next few days is a classic example of maritime winter confusion.
Sunday, January 18, looks like the trickiest day of the week. We’re expecting a mix of rain and snow with a high of 37°F and a low of 32°F. The chance of precipitation jumps to 65% by Sunday night, specifically for snow.
By Monday, the sun starts to peek out, but don't get too excited. The wind is going to kick up to a sustained 27 mph from the west.
Tuesday, January 20, is going to be the "stay inside and drink cocoa" day. The high is only 27°F, and the low drops to 24°F. When you combine those temps with the Montauk wind, it’s biting.

Why the Ocean Changes Everything
The ocean is a massive heat sink. It takes forever to warm up and forever to cool down.
This is why Montauk has such weird microclimates. In the spring, the "Ocean Effect" keeps the town chilly and foggy long after the cherry blossoms have popped in Manhattan. In the fall, the water stays warm, giving Montauk a "second summer" that locals swear is the best time of the year.
Usually, the coldest day of the year here is January 30, with averages ranging between 28°F and 38°F.
But "average" is a dangerous word in a place where a Nor’easter can turn a sunny morning into a horizontal sleet storm by lunchtime.
The Realities of Planning a Visit
If you're coming out here, you have to pack for three different seasons regardless of what the weather forecast montauk new york says.

- The Humidity Factor: Even in winter, the humidity is often above 70%. That "wet cold" gets into your bones much faster than a dry cold in the mountains.
- The Wind: It’s almost always windy. If it’s not a steady breeze, it’s a gust. The National Weather Service often has Small Craft Advisories active for the waters around Montauk Point for a reason.
- Visibility: Sea fog is real. It can roll in within ten minutes and cut visibility down to a few hundred feet.
Actionable Next Steps for Travelers
If you are heading to Montauk this week, here is the move.
First, ignore your phone’s generic weather app and check the marine forecast. Places like the Montauk Airport (KMTP) station provide much more accurate data for the actual coastline than a general "East Hampton" forecast.
Second, layer up. Waterproof shells are non-negotiable.
Finally, if you’re planning a boat trip or a hike at Camp Hero, keep a close eye on Sunday’s snow transition. With temperatures hovering right at the freezing mark, the difference between a rainy walk and a slushy mess is a matter of one or two degrees.
Montauk is beautiful when it's moody, but it's a lot more fun when you're actually dry.
