If you live in Eltingville, Annadale, or Huguenot, you already know the deal. You check the news, see a "New York City" forecast, and then walk outside only to realize the local weatherman clearly wasn't looking at the South Shore. Weather in Staten Island 10312 is its own animal. It’s not just "NYC weather" with a different zip code.
Being tucked down at the bottom of the map changes things. Honestly, the 10312 vibe is more like a coastal Jersey town than a concrete jungle. We get the ocean breeze. We get the weird humidity spikes. And yeah, we get the flooding that catches everyone by surprise.
The South Shore Microclimate Is Real
Most people think Staten Island is just one big block of weather. Wrong. There’s a massive difference between what's happening at St. George and what’s hitting us in the 10312.
Because we’re right there by the Raritan Bay, the water dictates our lives. In the spring, while people in the Bronx are wearing T-shirts, we’re often shivering in a 10-degree-colder "marine layer" because the Atlantic hasn't warmed up yet. It’s kinda frustrating. You drive over the Outerbridge and suddenly the temperature jumps.
Why the 10312 feels different
- The "Water Buffer": The bay keeps us slightly cooler in July but can keep us just above the snow line in January. You'll see rain in Annadale while it’s a blizzard in Todt Hill.
- Humidity: It’s thick. If the dew point hits 70 in the city, it feels like 80 on the South Shore. Basically, you’re breathing soup.
- The Wind: We don't have skyscrapers to break the gusts. When a storm comes off the water, it hits the 10312 first and hardest.
Surviving the Seasons in the 10312
January in the 10312 is... well, it's January. Right now, in early 2026, we’re seeing those classic "South Shore Swings." One day it’s 45 degrees and you think spring is coming early, and the next day the wind chill off the water makes it feel like 15.

Historically, January is our coldest month with average lows around 25°F. But the wind is the real killer. Those 13-15 mph average winds don't sound like much until you're standing at the Eltingville Transit Center waiting for the X1.
Spring and the "Mud Season"
By April, things get wet. It’s actually our wettest month on average. If you’ve got a basement in the 10312, you probably have a love-hate relationship with your sump pump.
The ground here is lower and closer to the water table. When we get those 4-inch rainfalls, the storm drains in neighborhoods like Greenridge can struggle. It’s not just about the rain; it’s about where the water has nowhere to go.
Summer: The Great Humidity Trap
July is the peak. Average highs sit around 85°F, but that’s a lie. With the humidity coming off the bay, the "feels like" temp is regularly in the 90s.

One weird thing about the 10312 is how thunderstorms behave. You’ll watch a massive cell on the radar coming across New Jersey, and then—poof—it hits the water and misses us completely, or it follows the Arthur Kill and hammers Rossville while leaving Eltingville bone dry.
The Elephant in the Room: Flooding
We have to talk about it. If you’re looking at property or living in the 10312, you know about the flood zones. FEMA isn't playing around here.
Zones like AE and VE are scattered all over the South Shore. If you’re near the creeks or the shoreline, you’re in a high-risk area. It’s not just about the big "once in a lifetime" hurricanes like Sandy. Even a heavy nor'easter at high tide can push water into the streets.
What to check before the next storm
- Check the Tide Clock: In the 10312, a heavy rain at low tide is a nuisance. A heavy rain at high tide is a disaster.
- Sump Pump Battery Backups: Power goes out in the South Shore more often than we'd like to admit. Don't let your basement flood just because the lights flickered.
- Leaf Debris: This is a big one. Our streets have lots of trees. If the catch basins are blocked by leaves, your street becomes a lake in 20 minutes.
Is the Weather in Staten Island 10312 Getting Crazier?
Long-time residents will tell you it feels that way. The data from the New York State Climate Hazards Profile suggests we're seeing more "extreme precipitation events." Translation: instead of a nice, steady rain, we get a month's worth of water in two hours.

The USDA recently updated its hardiness zones, and NYC is now sitting in Zone 7B. This means our winters aren't as consistently brutal as they were in the 70s or 80s, but the volatility is higher. You get these weird "false springs" in February that trick your plants into blooming, only for a frost in March to kill everything.
Practical Tips for Residents
Weather in Staten Island 10312 is manageable if you stop treating it like "Standard NYC Weather."
First off, get a hyper-local weather app. Something that uses crowdsourced data like Weather Underground or Windy. They often have stations right in 10312 backyards, which is way more accurate than a sensor at Newark Airport or Central Park.
Secondly, respect the ocean. If there’s a coastal flood advisory, move your car to higher ground. Even if it seems fine at 8 PM, the 2 AM high tide might have a different plan for your sedan.
Lastly, check your insulation. South Shore homes are often detached and exposed to those biting coastal winds. A little weatherstripping goes a long way when the wind is whipping off the bay at 30 mph.
Next Steps for You:
- Locate your specific flood zone using the FEMA Flood Map Service Center to see if your flood insurance is up to date for 2026.
- Install a water alarm in your basement near the sump pump; it's a $20 fix that saves thousands in flooring.
- Sign up for Notify NYC but filter it for Staten Island specifically so you aren't getting alerts for crane collapses in Manhattan.
