The best time to visit New Orleans depends on your personal preferences and what you want to experience in the city. Here are a few things to consider:
Spring (March-May): This is the best time to visit New Orleans if you want to experience the city's festivals and outdoor events. The weather is mild and comfortable, and there are many events such as the French Quarter Festival, the New Orleans Jazz and Heritage Festival, and the Tennessee Williams/New Orleans Literary Festival.
Summer (June-August): This is the peak tourist season in New Orleans, with the weather being hot and humid. If you're planning to visit during this time, be prepared for crowded streets, long waits at restaurants, and higher hotel rates. But, it's still a good time to enjoy the city's nightlife, music, and festivals.
Fall (September-November): The fall is a great time to visit New Orleans, as the weather is cooler and less humid, and there are fewer tourists. The city's famous Halloween and Day of the Dead parades take place during this time, and it's also a great time to enjoy the city's food and music.
Winter (December-February): This is the low tourist season in New Orleans, with cooler weather and fewer crowds. If you're looking for a budget-friendly option, and don't mind the cooler weather, this might be the best time to visit.
Keep in mind that Mardi Gras season is the peak of the high season, so if you're planning to visit during that time, you should book your accommodations well in advance, as hotels and Airbnbs fill up quickly.
