New Orleans, Louisiana Weather in September

September feels steamy

September is still hot in New Orleans, with afternoons near August's heat and sticky air that can make long walks tiring. Rain is common, often arriving in heavy showers, so a dry morning can turn wet quickly. It's also hurricane season, and storms can disrupt travel.

You can still explore the French Quarter, but take breaks inside places like the Cabildo or the National World War II Museum. Save longer outdoor walks for morning, and avoid planning a full afternoon in the sun. A family with young children may find the heat and sudden rain harder than a museum day.

Festivals and local plans

Southern Decadence, a large LGBTQ+ celebration, usually takes place over Labor Day weekend. It brings parties and crowds to the French Quarter, especially around Bourbon Street. If you're visiting then, expect a livelier scene and some busy sidewalks.

September is also football season for the New Orleans Saints. A game at the Caesars Superdome can add energy and visitors downtown, though the schedule changes each year. For a quieter evening, try a meal of red beans and rice in Tremé, then listen to live music on Frenchmen Street.

Crowds, costs and a local tip

Outside festival and game weekends, September is generally quieter than Mardi Gras or Jazz Fest season. Hotels can cost less than during those major busy periods, but prices and crowds rise around Southern Decadence and Saints home games. October is cooler and drier, so September's heat and rain are part of the trade-off.

For a practical break from the weather, ride the St. Charles streetcar beneath its oak canopy. It passes the Garden District, where you can hop off for a walk among historic homes, then return when the afternoon feels too hot. Check for service changes before you go, especially during heavy rain.
