Average Temperatures in New Orleans in August
New Orleans in August is typically hot and humid, with daytime high temperatures averaging in the lower 90s Fahrenheit (32-33°C).
Evenings remain warm, with average overnight temperatures generally in the mid-to-upper 70s Fahrenheit (around 24-26°C). Because of the high humidity, it can feel considerably hotter than the actual temperature, particularly during the afternoon.
If you plan to spend time walking around the French Quarter or exploring other neighborhoods, you may want to schedule your outdoor activities for the morning or later in the afternoon and evening.
How Hot Does It Get in New Orleans in August?
You can expect many days in August to reach at least 90°F (about 32°C), and some afternoons can climb into the mid-90s°F (35-37°C).
The combination of high temperatures and humidity can make August feel especially hot. Take breaks in air-conditioned spaces, drink plenty of water, and avoid spending extended periods in direct sunlight during the hottest part of the day.
Historically, temperatures in New Orleans have reached much higher levels during August, while cooler temperatures have also been recorded. These extremes are unusual, however, and typical August weather is characterized by consistently hot and humid conditions.
How Much Rain Does New Orleans Get in August?
August is one of the wetter months of the year in New Orleans, although rain does not necessarily mean that an entire day will be a washout.
Rainfall often comes in the form of brief but heavy showers and thunderstorms, particularly during the afternoon. It is possible to have bright sunshine in the morning followed by a heavy downpour later in the day.
On average, New Orleans experiences measurable rainfall on numerous days during August. However, many days also include periods of sunshine, so don't assume that a rainy forecast means you won't be able to enjoy your trip.
Thunderstorms can produce heavy rain, lightning, and gusty winds. If you're exploring outdoors when a storm develops, it's a good idea to take shelter and wait for it to pass.
How Much Sunshine Does New Orleans Get in August?
Despite the frequent summer showers, August still offers plenty of daylight for sightseeing.
Daylight hours gradually decrease throughout the month, but you will still have roughly 13 hours of daylight in early August and more than 12 hours by the end of the month.
This gives you plenty of time to explore New Orleans, especially if you plan your outdoor activities for the cooler parts of the day.
Does It Rain Every Day in New Orleans in August?
No. While August can be rainy, New Orleans does not typically experience all-day rain every day.
Summer thunderstorms often develop quickly and can produce heavy rain for a relatively short period. You may find that a shower interrupts your plans for an hour or two before the weather improves.
Because of this, it is a good idea to have a flexible itinerary. If rain is in the forecast, consider visiting an indoor attraction, enjoying a long lunch, or exploring one of New Orleans' many museums before heading back outside.
Hurricane Season in New Orleans
August falls within the Atlantic hurricane season, which runs from June through November.
New Orleans is located along the Gulf Coast, so tropical storms and hurricanes can affect the region during this time of year. However, the existence of hurricane season does not mean that a hurricane will affect your trip.
If you are visiting New Orleans in August, keep an eye on the weather forecast as your trip approaches. If a tropical system is developing in the Gulf of Mexico, monitor official forecasts and follow any guidance from local authorities.
Travelers with plans during hurricane season may also want to consider travel insurance that provides appropriate coverage for weather-related disruptions.
Is August a Good Time to Visit New Orleans?
August can be a good time to visit New Orleans if you are prepared for hot, humid, and sometimes rainy weather.
One advantage of visiting during this time of year is that you can often find a less crowded atmosphere than during some of the city's busiest travel periods. You may also find seasonal deals on accommodations and attractions.
The biggest drawback is the heat. Walking around New Orleans in August can be tiring, particularly during the middle of the day. If you don't enjoy hot and humid weather, you may prefer visiting during one of the city's cooler months.
If you do visit in August, plan your schedule around the weather. Start your day early, take advantage of indoor attractions during the afternoon, and save outdoor sightseeing for the morning or evening whenever possible.
What to Wear in New Orleans in August
The key to dressing for New Orleans in August is to stay cool, comfortable, and prepared for rain.
Lightweight, breathable clothing is your best choice. Loose-fitting shirts, shorts, lightweight pants, and breathable dresses can help you stay comfortable in the heat and humidity.
You should also bring:
- Comfortable walking shoes
- Lightweight, breathable clothing
- A hat or other sun protection
- Sunscreen
- Sunglasses
- A compact umbrella or lightweight rain jacket
- A refillable water bottle
- An extra shirt if you expect to be outside for several hours
If you're planning to walk around the city, comfortable shoes are particularly important. New Orleans is a great city to explore on foot, but the combination of heat, humidity, and long periods of walking can be challenging.
Don't forget that many restaurants, museums, shops, and other indoor attractions have strong air conditioning. You may appreciate having a lightweight layer with you when moving between the heat outside and heavily air-conditioned indoor spaces.
Tips for Exploring New Orleans in August
The heat and humidity don't have to keep you from enjoying the city. A little planning can make a big difference.
Start Outdoor Activities Early

Take an Afternoon Break

Stay Hydrated
Bring water with you when you're sightseeing. You may not realize how much you're sweating in the humidity, so make a point of drinking water regularly.
Be Prepared for Sudden Showers
Summer thunderstorms can develop quickly. Check the forecast before heading out and keep a small umbrella or rain jacket handy.
Plan for Flexibility
If you're visiting during a particularly rainy period, have a few indoor alternatives in mind. New Orleans has plenty of museums, historic buildings, restaurants, music venues, and other activities that can keep you busy when the weather doesn't cooperate.
