Honestly, if you've lived in Brooklyn for more than a week, you know the weather here has a mind of its own. One minute you're grabbing a latte in DUMBO under a clear sky, and the next, a "quick mover" system is dumping slush on your sneakers. Right now, everyone is obsessing over the Brooklyn weather 30 day forecast, trying to figure out if we’re in for a real "White Winter" or just thirty days of grey dampness.
The short answer? It’s complicated. As of January 17, 2026, we are staring down a classic January roller coaster. Today alone, we’re looking at a 100% chance of rain and snow with a high of 39°F. It’s that messy, heavy stuff that makes the G train platform feel even more like a subterranean grotto. But looking further out, the patterns are shifting in ways that might catch you off guard.
The Cold Truth About the Next Few Weeks
Basically, we’re dealing with a weak La Niña that's slowly transitioning to "neutral" territory. What that means for your morning commute is a lot of variability. While the National Weather Service has issued a Winter Weather Advisory for this weekend, the long-range outlook suggests that February might actually trend warmer than usual.
Look at the numbers for the immediate window:
- January 18 (Sunday): Snow showers are the main event. We're expecting 1 to 3 inches citywide, but don't be surprised if Brooklyn and Queens see slightly higher totals. Highs will hover around 36°F, dropping to a crisp 26°F at night.
- January 20 (Tuesday): This is where the "bitter" part of January kicks in. We’re talking a high of only 24°F and a low of 16°F. If you’re planning to be out, this is the day for the heavy wool coat.
- The "Deep Freeze" Stretch: From January 25 through the 27th, temperatures are projected to stay consistently low, with daytime highs struggling to break 23°F or 25°F.
It’s not just about the cold, though. The wind is a factor people always underestimate. By Monday, January 19, we’ll see southwest winds hitting 12 mph, which makes that 32°F high feel a lot more like 18°F.
What Most People Get Wrong About Brooklyn Snow
Everyone expects the "Big One" every time the local news mentions a flake. But looking at the Brooklyn weather 30 day forecast and historical trends for 2026, the reality is often "rain and snow" mixes. Because we’re tucked right against the Atlantic, that salt air keeps us just a few degrees warmer than upstate, often turning a potential blizzard into a slushy mess.

Take the current system: Sunday night has an 80% chance of snow, but the accumulation is only pegged at 2 to 4 inches. It’s enough to make Prospect Park look like a postcard for exactly three hours before the salt trucks and foot traffic turn it into grey goop.
Why the End of January Looks Different
If you’re a fan of the cold, enjoy it while it lasts. The Almanac and Climate Prediction Center are both hinting at a shift as we move into February. While late January stays sunny and colder, the start of February (Feb 1-4) is looking rainy and milder.

It’s a weird cycle. We go from "frozen tundra" to "springtime drizzle" in the span of 48 hours. This transition is typical for an ENSO-neutral year. You'll want to keep both your heavy-duty parka and your waterproof Chelsea boots by the door because you’ll likely need both in the same week.
Survival Guide for the 30-Day Outlook
If you're trying to plan your life around this forecast, here’s the breakdown of what's actually happening on the ground.
- The Monday Reveal: After the snow on Sunday, Monday (Martin Luther King Jr. Day) will be sunny but deceptive. With a high of 32°F and wind gusts up to 30 mph, it’s a "stay inside and order Thai food" kind of day.
- The Mid-Week Tease: Thursday, January 22, brings another round of rain and snow. Highs will hit 37°F, which means whatever falls will likely be wet and heavy.
- The February Pivot: Expect the first half of February to be significantly wetter. We’re talking about 10 days of rainfall on average for the month, with temperatures potentially jumping 5 degrees above the historical average.
Actionable Steps for Brooklynites
Stop checking the app every five minutes; it's going to change. Instead, prep for the specific volatility of the next 30 days.
- Seal the Drafts: Since we're hitting 14°F lows around January 25th, check your window seals now. Brooklyn brownstones are notorious for letting the heat escape.
- Salt the Sidewalk Early: If you're a homeowner or a super, Sunday’s snow (Jan 18) is expected to be 80% likely. Get the salt down before the Sunday night freeze hits.
- Plan Travel for the "Sunny Gaps": January 19, 20, and 23 look mostly sunny or partly sunny. These are your best windows for moving furniture or doing anything that requires being outdoors for more than twenty minutes.
- Watch the Bridge Closures: Be aware that infrastructure work, like the Shore Road Bridge closure scheduled for January 20th, often relies on these weather windows. If it snows, expect city-wide delays on maintenance and transit.
The Brooklyn weather 30 day forecast is basically a lesson in patience. We have a solid week of genuine winter ahead, followed by a slow, messy thaw into a milder February. Layer up, keep the umbrella handy, and remember—at least it’s not as cold as Buffalo.
