However, if you’re looking to save a bit more cash, the best time to visit is during the off season between the months of June to September. Temperature wise, the best time to visit is between February to May as the weather is mild and easy to manage. Mardi Gras season lasts from January to March, while those who want to enjoy the festivals in Louisiana should come by during the last week of April and the first week of May.
