If you've ever spent a winter morning down by the State Pier, you know that the weather for New Bedford MA is basically a conversation between the Atlantic Ocean and the stubborn cold of New England. It’s a coastal city. That means the water is usually the boss.
Tonight, Saturday, January 17, 2026, the city is sitting under a thick blanket of clouds. It’s 40°F out there right now, but with the wind coming off the west at 14 mph, it actually feels more like 32°F.
Honestly, that’s New Bedford for you. The numbers on the thermometer rarely tell the whole story when the humidity is hanging at 71%.
What the Forecast Actually Means for Your Weekend
The current setup is kind of a classic January mix. We’ve had a high of 46°F today, which is technically "warmer" than the usual 38°F average for this time of year, but the dampness makes it feel raw.
If you are heading out tonight, keep an eye on the sky. There’s a 20% chance of snow as the temperature dips toward a low of 31°F. It’s not a blizzard, but enough to make the cobblestones in the Whaling District a little slick if that moisture freezes up.
Tomorrow is where things get interesting. The forecast for Sunday, January 18, is calling for a 100% chance of precipitation. It starts as a rain-snow mix in the morning and likely transitions to straight snow by the afternoon.
Total accumulation? We are looking at about 1 to 3 inches.
Why the "Buzzards Bay Buffer" Matters
People often get frustrated when the Boston stations predict a foot of snow and New Bedford barely gets a dusting. There is a real reason for that.
The city sits right on Buzzards Bay. Because the ocean stays relatively "warm" (around 40°F in mid-January), it often acts as a heat sink. This creates a microclimate where the immediate coast stays just above freezing while the towns further inland, like Freetown or even parts of North Dartmouth, are getting hammered with heavy snow.
That 15 mph wind from the southwest we are seeing today? That’s bringing in slightly milder maritime air. It’s the reason the current conditions are cloudy and damp rather than clear and frigid.

Long-Term Patterns and What to Expect
January is historically the coldest month here, with the average low hovering around 22°F. We are currently beating those averages, but don't get too comfortable.
- Cloud Cover: It's overcast about 51% of the time this month.
- Wind Loading: New Bedford is actually in a 110 mph wind load zone—the highest in the state—due to our exposure to coastal storms and Nor'easters.
- Flooding Risks: The Barrier Gate usually does its job, but with sea levels rising, the city is using dynamic models like the Massachusetts Coast Flood Risk Model (MC-FRM) to map out how the 1,000-year storms might look by 2030.
Sea surface temperatures are currently around 39°F to 40°F. When a cold front hits that "warm" water, you get the gray, misty, bone-chilling weather that New Bedford is famous for.
Actionable Steps for New Bedford Residents
Since we are looking at a 100% chance of snow/rain tomorrow, there are a few things you should actually do.
First, if you live in the South End, check your drainage. The 71% humidity means the air is already saturated; any significant rain before the snow will pool quickly.
Second, the wind is expected to be light and variable tomorrow, but the "feels like" temperature will stay in the 20s. Layer up with a windproof shell. Standard wool coats get heavy and useless in the New Bedford dampness.

Finally, keep an eye on the transition timing tomorrow afternoon. If the temperature drops faster than expected, that 1-3 inches of snow will bond to the wet pavement, making the evening commute on Route 18 a mess.
Check the local tide charts if you are near the Clark’s Point area. While no major coastal flooding is forecast for this specific system, the combination of a 100% precipitation chance and high tide can sometimes cause minor backup in street drains.
Stay dry, watch the ice on the side streets, and enjoy the rare sight of snow on the masts of the fishing fleet tomorrow evening.
