September marks a transitional period for New Orleans as the summer heat begins to moderate.
Average high temperatures drop from August's 91°F (33°C) to 87°F (31°C), while lows hover around 72°F (22°C).

Impact & Risks

The ongoing hurricane season poses a risk to the region, with the potential for severe weather events through mid-October. Visitors should remain vigilant and monitor weather updates during this period. While the summer heat begins to ease, the high humidity levels can still make outdoor activities uncomfortable, particularly during the early part of the month. However, the arrival of late-September cold fronts can bring significant relief, making the weather more pleasant for outdoor activities and events. Travelers should also be prepared for occasional heavy rainfall, which is typical for this time of year.
