New Orleans, Louisiana Weather in August

August heat and rain

August in New Orleans feels hot and sticky, with warm nights and frequent rain. Showers can interrupt a walk through the French Quarter, and the high humidity makes long afternoons outdoors tiring. July is just as hot, while September is a little cooler and less rainy.

Plan shorter outdoor visits around the weather. The air-conditioned galleries at the National World War II Museum offer a welcome break, and you can explore the French Quarter between showers. Save long walks along the Mississippi riverfront for cooler parts of the day. A swamp tour can still run, but the heat and rain may make it less comfortable.

Events and quieter streets

Satchmo SummerFest celebrates Louis Armstrong, a New Orleans-born jazz great, with music and talks around the New Orleans Jazz Museum. COOLinary New Orleans also brings special menus to participating restaurants, so you can try local cooking without relying only on the usual menus.

August is summer low season, unlike the busy Mardi Gras period and popular spring months. You'll usually find fewer visitors and better hotel deals, though weekends and events can still draw crowds. For families, the quieter streets can be a relief, but afternoon heat may cut outdoor sightseeing short.

A local way to cope

Use the St. Charles streetcar to see the Garden District without walking the whole route in the heat. It's a scenic ride past historic homes and oak-lined streets, with air-conditioned stops and cafes nearby for a break. The streetcar itself isn't air-conditioned, so it can still feel warm.

For dinner, try a COOLinary menu or order a bowl of gumbo in an air-conditioned restaurant. Keep an umbrella handy for sudden showers, especially if you're crossing between the Quarter and the riverfront. Don't expect August to feel like a beach holiday: it's better suited to flexible city days, indoor sights and music breaks.
