March in New Orleans is a total mood ring. One minute you are sitting on a wrought-iron balcony in the French Quarter, soaking up a perfect $74^{\circ}\text{F}$ breeze that feels like a literal hug from the universe. The next? A sudden "gully washer" turns the cobblestone streets into tiny rivers and sends you sprinting for the nearest awning.
Honestly, the weather is the city’s favorite punchline.
People often assume that because it's the South, March is basically summer-lite. It isn't. Not even close. While the rest of the country is still shaking off the last of the snow, New Orleans is waking up, sure, but she’s also a bit temperamental. You've got azaleas blooming in bright fuchsias and whites, but you also have high-pressure systems that can drop the temperature by twenty degrees in three hours.
If you’re planning a trip, you need to know that new orleans weather march isn't a single "season"—it’s a transition. It’s the sweet spot before the air becomes a thick, humid soup in July, but after the damp, bone-chilling cold of January.
The Reality of New Orleans Weather March Averages
Let’s talk numbers, but take them with a grain of sea salt. Historically, the average high hits right around $73^{\circ}\text{F}$ ($23^{\circ}\text{C}$), while the lows hover near $54^{\circ}\text{F}$ ($12^{\circ}\text{C}$).
That sounds pleasant. It is pleasant.
However, "average" is a sneaky word in Louisiana. You might get a week where every single day is a flawless $78^{\circ}\text{F}$. Or, you might run into a "Blue Norther" that pushes a cold front down from the plains, leaving you shivering in $45^{\circ}\text{F}$ rain during a St. Paddy's Day parade.
Humidity: The Silent Factor
Humidity in March usually sits around 73%. In July, that would be a death sentence for your hair and your spirit. In March? It actually feels kinda nice. It keeps the air from feeling brittle. The dew point hasn't reached that "I need a third shower today" level yet. It's just enough moisture to make the smells of blooming jasmine and fried beignets hang in the air a little longer.
Rainfall and "The Grey"
March isn't the wettest month—that honor usually goes to June or July—but it’s not dry either. You’re looking at about 4.8 inches of rain spread over 8 or 9 days.
Most of the time, these aren't all-day soakings. They are cinematic, heavy downpours that last 20 minutes and then vanish, leaving the pavement steaming. But when it rains in the Big Easy, it really rains. The city is essentially a bowl, so the drainage system works hard, but a heavy March thunderstorm can cause some localized street flooding.
Why Everyone Forgets to Pack for the Night
This is the biggest mistake travelers make. You see a forecast of $75^{\circ}\text{F}$ and you pack shorts and tanks.
Big error.
When the sun goes down over the Mississippi River, the temperature can plummet. That $75^{\circ}\text{F}$ afternoon quickly turns into a $55^{\circ}\text{F}$ evening. If you’re standing on a windy corner waiting for a streetcar, you’re going to be miserable in a T-shirt.
Layering is the only way to survive.
I’m talking about a light denim jacket, a pashmina, or a hoodie you can tie around your waist. You’ll look like a local who knows what’s up. Plus, the air conditioning in New Orleans restaurants is legendary. Even if it's warm outside, some of those old-school Creole dining rooms feel like meat lockers.
- Shoes: Bring two pairs. At least. One should be something you don't mind getting wet or dirty. The streets of the French Quarter aren't always... pristine.
- Umbrella vs. Poncho: An umbrella is great for a light drizzle, but if a real storm hits, the wind will turn it inside out. A high-quality, packable rain shell is a better bet.
- Sunscreen: Don't let the clouds fool you. The UV index in New Orleans starts climbing fast in March. You can get a nasty burn while sitting through a three-hour jazz brunch.
Festivals and the Weather Gamble
March 2026 is shaping up to be a busy one. Since Mardi Gras fell on February 17 this year, March is all about the "Spring Fiesta" and the massive St. Patrick’s Day celebrations.
If you’re heading to the Irish Channel St. Patrick’s Day Parade (usually around March 14), the weather is part of the sport. Watching people throw cabbages and carrots from floats while the sun beats down is a core New Orleans memory. But if the "March winds" are kicking up, those cabbages have some serious velocity.
Then you have the New Orleans Spring Fiesta starting mid-month. This is when the weather is usually at its peak "Goldilocks" state—not too hot, not too cold. It’s the best time to do a walking tour of the Garden District. The oak trees are draped in new, bright green leaves, and the air smells like sweet olive.
Practical Advice for Your March Trip
If you’re checking the 10-day forecast and see rain every day, don't panic.
Weather apps often show a "30% chance of rain" for every single day in New Orleans because of our subtropical climate. It usually just means a stray shower might pop up. It rarely means your whole day is ruined.
Watch the wind.
March is actually one of the windier months in the city, averaging about 14 mph. If you’re planning a swamp tour or a boat ride on the Steamboat Natchez, it’ll feel significantly cooler on the water. Bring a windbreaker.

Allergies are real.
If you suffer from hay fever, March is your boss fight. The oak pollen is no joke. It covers everything—cars, tables, your lungs—in a fine yellow dust. Pack your antihistamines.
The Snowball Factor.
One of the surest signs that the weather has officially turned is the reopening of the neighborhood snowball stands. When you see a line forming at Hansen’s Sno-Bliz or Pandora’s, you know winter is dead. Even if it's only $70^{\circ}\text{F}$, a snowball is a rite of passage.
Basically, New Orleans in March is a gamble that almost always pays off. Even a "bad" weather day here is better than a good day in a cubicle. Just be ready to pivot. If it rains, duck into a bar. If it's hot, find a courtyard. If it's cold, order an extra bowl of gumbo.
To make the most of your trip, start monitoring the local NOLA weather stations about three days before you fly out. The "extended" forecasts are mostly guesswork. Stick to the short-term updates for accuracy. Pack that extra layer, bring some comfortable walking shoes that can handle a puddle, and grab some allergy meds if you're sensitive to pollen. You'll be perfectly prepared to handle whatever the sky decides to do.
