New Orleans isn't exactly where you go to find a winter wonderland. Usually, "winter" here means a slightly less humid Tuesday where you might actually need a light cardigan. But if you’ve lived in the Crescent City long enough, you know that when it actually decides to snow, the entire city loses its collective mind—and for good reason.
Honestly, the New Orleans snow totals for most of the last century have been a joke. We're talking "dusting on a windshield" territory. But that changed on January 21, 2025. That day didn't just break records; it basically rewrote the atmospheric rulebook for South Louisiana. Before that, the conversation always went back to 1895, a year so far in the past it felt more like a tall tale than actual weather data.
The Day the Big Easy Froze: The 2025 Blizzard
Most of us weren't prepared for what happened in early 2025. National Weather Service (NWS) forecasts originally called for maybe two inches. Instead, a moisture-heavy Gulf low collided with an Arctic blast that had plummeted all the way down from the Yukon.
The result? New Orleans officially clocked in 10 inches of snow at Louis Armstrong New Orleans International Airport (MSY).
Some parts of the metro area, specifically over in Chalmette and lower St. Bernard Parish, reported totals as high as 11.5 inches. If you were standing in the French Quarter that morning, you saw the statue of Andrew Jackson buried under more white powder than a plate of beignets at Cafe Du Monde. It tied the legendary 1895 "Great Snow" for the city's official record, though many locals argue it felt much heavier because the humidity made the snow exceptionally dense and wet.
A History of New Orleans Snow Totals (Or Lack Thereof)
Before 2025 came along and ruined the curve, New Orleans had a very sparse relationship with the white stuff. If you check the NOAA archives, you’ll see long stretches of absolutely nothing.
Take the 2004 "Christmas Miracle." People still talk about that one because it happened on Christmas Eve. It was magical, sure, but the actual accumulation was barely an inch in the city itself. It looked great on camera, but it wasn't exactly a "total."
Then there was December 11, 2008. That was a weird one. It was the earliest "significant" snow on record at the time. The airport officially recorded 1.0 inch, which actually stood as the modern-day high-water mark for a long time. It was enough to shut down the Causeway and make everyone buy out the bread and milk at Rouses, but compared to 2025, it was a rounding error.
Comparing the Heavy Hitters
If we look at the historical data, the list of measurable snow in New Orleans is surprisingly short.
- February 14–15, 1895: The gold standard for over a century. The city saw 8.2 inches officially, though some historical accounts claim 10 to 12 inches fell in the outlying areas.
- January 21, 2025: The new king. 10 inches officially at MSY. This event was a true "Gulf Coast Blizzard," featuring whiteout conditions that haven't been seen here in living memory.
- February 12–13, 1960: A solid 4.4 inches. This was the snow that your grandparents probably still brag about surviving.
- January 11, 1973: 3 inches. This one was notable because it stayed on the ground for a bit due to sub-freezing temperatures that lingered after the front passed.
- December 8, 2017: 2.1 inches. Most people remember this because it happened so early in the morning that by lunchtime, half of it had already turned into a slushy mess.
Why Does It Happen So Rarely?
You've gotta understand the physics here. New Orleans is basically a bowl surrounded by water. Between Lake Pontchartrain and the Gulf of Mexico, there is a massive amount of "warm" water nearby. Water holds heat way better than land does.
For it to snow here, you need a "perfect storm" of three specific things:
- Arctic Air: A cold front has to be strong enough to push all the way to the coast without being moderated by the Gulf.
- Moisture: Usually, when it gets that cold, the air is bone-dry. You need a low-pressure system to swing over the Gulf and pump moisture back into that cold air.
- Timing: If that moisture arrives two hours too late, the sun is up, the ground is 40 degrees, and you just get a cold, miserable rain.
In 2025, those three things hit at the exact same time. It was a statistical anomaly that meteorologists are still studying.
The Infrastructure Nightmare
Let’s be real: New Orleans isn't built for this. We don’t have salt trucks. We don't have snowplows. We have bridges that are essentially giant ice skates the second the temperature hits 31 degrees.

During the 2025 event, the Twin Span and the Hale Boggs bridge were closed for nearly three days. The "totals" mattered less than the ice. In South Louisiana, snow is almost always preceded or followed by sleet and freezing rain.
When you see a report of 8 or 10 inches, remember that underneath that is likely a layer of solid ice. Our power grid, already stressed by summer humidity, tends to struggle when ice builds up on the lines. During the 2021 winter storm (which only gave the city about 0.5 inches of "wintry mix"), thousands lost power because of ice, not snow.
How to Track Future Totals
If you're looking for the most accurate data, skip the random apps. You want the NWS New Orleans/Baton Rouge office (KLIX). They operate out of Slidell and are the ones who actually go out and measure the snowfall at the airport.
You should also keep an eye on CoCoRaHS (Community Collaborative Rain, Hail & Snow Network). It’s a group of volunteers who use manual gauges. During the 2025 storm, CoCoRaHS reports were actually more helpful for seeing the variation between, say, Uptown New Orleans and Kenner, because the airport's official reading doesn't always reflect what's happening in the heart of the city.
Preparing for the Next Flurry
Given the weirdness of the 2025 totals, it's clear that "it never snows in New Orleans" is no longer a safe bet. You don't need a snowblower, but you do need a plan.
- Drip your pipes: This is the big one. Our houses are often raised and have exposed plumbing. A hard freeze is more dangerous than the snow itself.
- Check your plants: Citrus trees and tropicals (like those banana trees everyone has) will die at 28 degrees. If snow is in the forecast, wrap them.
- Stay off the overpasses: If there is even a trace of snow, stay home. New Orleans drivers have zero experience with traction on ice. It’s not a lack of skill; it’s a lack of equipment.
The 2025 records might stand for another 130 years, or we might see a shift in weather patterns that brings more of this. Either way, the "snow totals" for NOLA are finally a serious data point instead of a weather footnote.
If you’re tracking a current storm, check the local radar for "bright banding"—that’s often a sign that the rain is starting to turn into wet snow or sleet before it hits the ground. Keep your car gassed up and your pantry stocked, because when it snows in the Big Easy, the city effectively hits the pause button.
