What you need to know about the weather in New Orleans

the weather in New Orleans

New Orleans is a city with a unique and often unpredictable climate. Situated on the Gulf Coast, the weather in the Big Easy can be a mix of sultry summer heat, sudden thunderstorms, and even the occasional winter chill. Whether you’re a local or planning a visit, it’s important to understand the ins and outs of the weather in this vibrant southern city.

The Humid Subtropical Climate

New Orleans has a humid subtropical climate, which means hot, humid summers and mild, damp winters. The average high temperature in the summer months of June through August is around 90°F (32°C), with lows around 75°F (24°C). It’s not uncommon for the mercury to reach the mid to high 90s Fahrenheit (mid 30s Celsius), especially during heat waves.

The humidity is what really makes the summer heat stand out, though. The Gulf of Mexico is the source of this persistent moisture, which can make the air feel thick and heavy. Combine that with New Orleans’ low elevation and you have a recipe for some seriously sweltering summer days.

Thunderstorms are also a common occurrence during the summer months. Afternoon and evening thunderstorms often roll in, bringing heavy downpours, strong winds, and even the occasional tornado. These storms can develop quickly, so it’s a good idea to keep an eye on the forecast and have a plan to seek shelter if necessary.

Mild, Damp Winters

In contrast to the hot, humid summers, winters in New Orleans are relatively mild. Average high temperatures from December through February range from the 60s to low 70s Fahrenheit (15-22°C), with lows in the 40s and 50s Fahrenheit (7-13°C). Frost and freezing temperatures are rare, though they do happen occasionally.

While winter may be the most comfortable time of year weather-wise, it also brings increased rainfall. December and January are the wettest months, with average rainfall around 5 inches (12 cm) per month. The winter storms can be intense, with heavy downpours, strong winds, and even the possibility of tornadoes.

Hurricane Season

One of the biggest weather concerns in New Orleans is the threat of hurricanes during the Atlantic hurricane season, which runs from June 1st to November 30th. The city’s low elevation and proximity to the Gulf of Mexico make it particularly vulnerable to the impacts of these powerful storms.

Notable examples include Hurricane Katrina in 2005, which devastated the city and surrounding region, and Hurricane Ida in 2021, which caused widespread damage. When a hurricane is approaching, it’s crucial for residents and visitors to closely monitor the forecast, heed any evacuation orders, and be prepared with an emergency plan and supplies.

Adapting to the Weather

Given the extreme heat, humidity, and hurricane risk, it’s important for both residents and visitors to New Orleans to be prepared for the unpredictable weather. Some tips include:

  • Staying hydrated and seeking shade or air conditioning during the hottest parts of the day
  • Packing light, breathable clothing for the summer months
  • Having a plan in place for severe weather, including knowing the location of the nearest storm shelters
  • Purchasing travel insurance that covers trip cancellations or interruptions due to hurricanes

Overall, the weather in New Orleans is a unique and often challenging aspect of experiencing this vibrant city.
