If you’re planning a trip to the "City by the Sea," you’ve probably noticed that long beach ny weather isn’t exactly what you’d find in Manhattan or even further inland on Long Island. It’s got a personality of its own. Honestly, the ocean dictates everything here. One minute you’re enjoying a crisp breeze on the boardwalk, and the next, a wall of fog rolls in off the Atlantic, making you feel like you’ve been dropped into a movie set.
Living here or visiting means understanding that the forecast is basically a suggestion. The water acts as a giant thermostat. In the heat of July, when the rest of New York is melting on the subway, Long Beach is usually about 5 to 10 degrees cooler. But that same water keeps things just a bit warmer when the first frost hits the mainland.
Why the Ocean Changes Everything
It’s all about the maritime influence. Because Long Beach is a barrier island, it’s surrounded by water—the Atlantic to the south and Reynolds Channel to the north. This creates a microclimate that can be baffling if you aren't ready for it.
You’ll see it most in the spring. While flowers are blooming in Queens, Long Beach might still be shivering in a damp, salty mist. The ocean stays cold way longer than the land does. So, even if it’s 70 degrees in the city, that "sea breeze" coming off 45-degree water will make you reach for a hoodie.
On the flip side, the fall is glorious. September is arguably the best month on the island. The ocean has spent all summer soaking up the sun, and it holds onto that heat. While the rest of the state is thinking about pumpkins and coats, we’re often still in shorts, enjoying 70-degree days and water that's actually warm enough to swim in.

A Real Look at the Seasons
Don't expect the generic Northeast weather patterns you see on the news. Here is what actually happens on the ground throughout the year.
The Summer Rush (June to August)
This is peak time. Everyone wants to be here. Average highs hover around 80°F, but it's the humidity that gets you. However, unlike the stifling heat of a city block, the wind is almost constant. If the wind is coming from the South, it’s refreshing. If it stalls or shifts from the West, it can feel like a sauna. Watch out for those late-afternoon thunderstorms; they roll in fast and can turn a beach day into a scramble for cover in minutes.
The Long Fall (September to November)
This is when the locals finally get the beach back. The humidity drops, the air gets crisp, and the sky turns a deep, clear blue. October temperatures stay pretty mild, usually in the 60s. It's perfect for biking the boardwalk. Just know that this is also the tail end of hurricane season. While big hits are rare, the "Nor'easters" start to pick up, bringing heavy rain and impressive (and sometimes scary) surf.
The Winter Bite (December to March)
Winter in Long Beach is... intense. It’s not just the cold; it’s the wind. A 35-degree day feels like 15 when the wind is whipping off the water at 25 mph. We don't always get as much snow as the "mainland" because the salt air and slightly warmer ocean temps often turn snow into a slushy rain. But when it does snow, the dunes look incredible. It’s quiet. Desolate. If you like moody, coastal vibes, this is your time.

The Unpredictable Spring (April to May)
Basically, don't trust May. You might get a 75-degree "teaser" day followed by three days of 48-degree drizzle. This is the season of the "sea fret" or heavy coastal fog. You’ll be standing on the sand and literally won't be able to see the water. It’s weirdly beautiful but damp.
What Most People Get Wrong About Long Beach Weather
A common mistake is checking the "New York City" forecast and assuming it applies here. It doesn't.
Many visitors arrive in June wearing tank tops only to find out that the sea breeze has kept the beach at a shivering 62 degrees while Penn Station was a sweltering 85. Always check a specific Long Beach or Atlantic Beach station. Also, the UV index on the island is no joke. Because of the reflection off the sand and the water, you will burn much faster here than you would in a backyard in the suburbs. Even on a cloudy day, the "Long Beach burn" is a real thing.
Safety and the "F" Word: Flooding
We have to talk about it. Living on a sandbar means water is part of life, sometimes in places you don't want it. Minor "sunny day flooding" happens during high tides, especially during full moons.

If there’s a storm surge combined with a high tide, the streets near the bay (the North side) can fill up fast. Locals know the spots to avoid. If you see a puddle that looks like a small pond on West Park Ave or near the channel, don't drive through it. Saltwater is brutal on cars.
Actionable Tips for Your Visit
To make the most of long beach ny weather, you need a bit of a strategy.
- The Layer Rule: Even in July, bring a light sweatshirt if you plan to stay past sunset. The temp drop when the sun goes down over the water is sharp.
- Wind Apps are Key: Download a wind-tracking app like Windy or Surfline. If the wind is over 15 mph from the South, it’s going to be a "sand-blasting" kind of day on the beach.
- The September Sweet Spot: If you want the best weather with the least amount of tourists, book your trip for the second or third week of September.
- Check the Tides: If you're coming for a beach walk, go at low tide. The "hard sand" revealed by the receding tide is much easier to walk on than the soft stuff near the dunes.
Next time you're looking at the clouds over the Atlantic, just remember: if you don't like the weather in Long Beach, wait twenty minutes. It’ll probably change. Check the local tide charts before you head out, and always, always keep a windbreaker in your trunk.
