If San Diego has a dry subtropical climate, New Orleans definitely has a humid subtropical climate! The sweltering heat and frequent heavy rains make summer the most challenging and least recommended season to visit New Orleans. 

Temperatures and Rainfall in New Orleans

New Orleans' climate effectively creates two macro-seasons; forget the traditional four seasons. To simplify, we consider just the summer and winter seasons. Temperatures remain mild during the winter season, making outdoor activities, including walking tours of the city, enjoyable. 
In contrast, during the summer season, humidity makes the air heavy and increases the sensation of heat, and the heavy rains make it difficult to explore the various neighborhoods. Additionally, this period marks the start of the hurricane season.

Rainfall is abundant all year round but intensifies during the summer season, from May to late September, and starts to decrease in October. 
Let's take a look at a summary table of temperatures and rainfall.

Winter in New Orleans

January and February are the months with the lowest minimum temperatures, almost never below 45°F (7°C), while the averages are around 54°F (12°C) reaching highs of 60-64°F (16-18°C). So, we’re talking about a mild winter with never too heavy rainfall. The climate is therefore favorable for outdoor activities and exploring historic neighborhoods.

With such favorable weather, there is no shortage of events and festivals, from jazz music festivals to the magical Mardi Gras of New Orleans.

Summer in New Orleans

In summer, starting from June, the heat is felt, the rains become more abundant, and the hurricane season begins. Maximum temperatures exceed 86-95°F (30-35°C) and the humidity makes everything heavier. It is difficult to explore the city, and if you have a choice, these are the least recommended months for travel.

Spring (March/April/May) is the most variable season with pleasant nighttime minimum temperatures ranging from 55-60°F (13-16°C) while daytime temperatures can reach up to 77-86°F (25-30°C). Particularly sunny days will be the hottest, with refreshing sea breezes providing relief.

October marks the start of the dry season, with scarce rainfall and temperatures gradually dropping to 61-66°F (16-19°C) in November. Undoubtedly, the best season for a trip to this area of the United States and to visit the Jazz capital: New Orleans.

The Best Time to Visit

If you have the option to choose, avoid the summer and visit New Orleans and its surroundings from October to April, remembering that you will find more events during the winter months.
