March Weather and Packing Essentials
Weather in New Orleans during March is a transition from late winter to early spring. According to 30-year climate normals (1991–2020) from the National Oceanic and Atmospheric Administration (NOAA), the city sees an average daily high of 73.0°F and an average low of 54.1°F. Travelers should expect a mix of sunshine and spring showers, with March averaging 4.61 inches of precipitation. Humidity remains moderate, making it ideal for walking tours through historic districts.
Packing requires layers. A day starting at 55°F often climbs to 75°F by mid-afternoon. Prioritize breathable fabrics like cotton, but bring a light jacket for evening jazz shows. A compact travel umbrella is essential due to sudden showers. Most importantly, bring broken-in walking shoes; the city’s historic slate sidewalks are notoriously unforgiving to improper footwear.
Major March Festivals and Events
March marks the start of "festival season." The 2027 calendar includes the Tennessee Williams & New Orleans Literary Festival (March 17–21) and the New Orleans Book Festival (March 11–14). These events bring world-class writers to the French Quarter and Tulane University for workshops and performances. If you plan to attend, booking a hotel in the French Quarter or Warehouse District early is recommended to stay within walking distance of the primary venues.
St. Patrick’s Day celebrations are a multi-day highlight. The 2027 Irish Channel St. Patrick's Day Parade is scheduled for Saturday, March 13, at 1:00 p.m., famous for throwing cabbages and potatoes for Irish stew. Other key dates include the Metairie Road Parade (March 14) and the Downtown Irish Club Parade (March 17). Additionally, the Hogs for the Cause barbecue and music festival takes place March 19–20, 2027, at the UNO Lakefront Arena.
Mardi Gras Indian Super Sunday Guide
Super Sunday is a traditional gathering of Mardi Gras Indian tribes, who take to the streets in hand-sewn, feathered suits. The Uptown Super Sunday celebration is scheduled for Sunday, March 21, 2027, centering around A.L. Davis Park at noon. This is a community-focused event rooted in African American history. Unlike Mardi Gras parades, there are no barricades; the crowd moves with the Indians. Visitors should give suit-wearers space and ask permission before taking close-up photographs, as these garments are fragile works of art.
3-Day New Orleans March Itinerary
Day 1: French Quarter and Marigny. Start at Jackson Square and the St. Louis Cathedral, then browse Royal Street’s antique galleries. In the evening, visit Frenchmen Street in the Marigny for live jazz at clubs like Snug Harbor. The cooler March air makes hopping between venues pleasant.
Day 2: Garden District and Magazine Street. Take the St. Charles Avenue streetcar to the Garden District to see blooming azaleas. Visit the historic mansions and Commander’s Palace before heading to Magazine Street for boutique shopping. For dinner, request courtyard seating at restaurants like Sylvain to enjoy the spring weather.
Day 3: Mid-City and Bayou. Explore City Park’s Besthoff Sculpture Garden, which is free and shaded by live oaks. Alternatively, March is excellent for swamp tours as reptiles emerge from winter dormancy. Many swamp tours offer hotel pickups, but these should be booked at least 48 hours in advance during this busy season.
Crawfish Season and Seasonal Dining
March is the peak of crawfish season in Louisiana. Participating in a crawfish boil is a quintessential experience, with local favorites like Bevi Seafood Co. or Clesi’s offering traditional boils seasoned with cayenne, lemon, and garlic. Beyond crawfish, focus on outdoor dining. Many historic restaurants feature hidden courtyards that are only comfortable during these spring months. Secure reservations for popular spots like Peche several weeks in advance to avoid long wait times.
Navigating the Post-Mardi Gras Transition
In 2027, Fat Tuesday falls on February 9. By March, the city has transitioned into its "spring festival" identity. This period is distinct from Carnival; while there are still parades, the focus shifts toward neighborhood celebrations and specialized festivals. The "Lenten lull" is non-existent, as spring break travelers and convention-goers keep the city at high capacity. Lodging should be secured months in advance to avoid inflated seasonal rates and limited availability.
What to verify before you go:
- Parade Routes: Routes for St. Patrick's Day can change; check the St. Patrick's Day New Orleans official site for 2027 maps.
- Festival Tickets: Events like Hogs for the Cause require advance tickets; verify availability on official websites.
- Transit Alerts: The RTA may alter streetcar schedules during parades; use the Le Pass app for real-time updates.
- Reservations: Peak season demand is high; verify table availability via Resy or OpenTable 2-3 weeks in advance.
- Weather: Check the National Weather Service New Orleans station for 48-hour outlooks on sudden spring storms.

Book March weekends earlier than the weather suggests
March looks like shoulder season on a weather chart and behaves like high season on a booking calendar. The event stack — St. Patrick’s parades, Super Sunday, early festival season and spring break overlapping conference traffic — compresses hotel supply on specific weekends while leaving midweek comparatively open. The practical response: if your dates are fixed to a March weekend, price hotels as soon as the trip is real and favor refundable rates, which let you rebook if prices soften. If your dates are flexible, the same trip run Sunday to Thursday routinely costs meaningfully less and queues shorter at every restaurant you care about. Check the parade calendar against your hotel’s address before booking, too — a route one block away is a delight if you want it and a hard noise-and-access problem if you do not, and March is the month when that distinction matters most.
