Climate

The climate of the Greater New Orleans region can best be described as humid and subtropical. Though rainfall can occur throughout the year, the area is largely shielded from extreme weather conditions by surrounding waterways.

January through March of each year is characterized by mild winter conditions that gradually warm into comfortable spring temperatures. Snowfall is extremely rare (last occurring in December 2008), though nighttime freezing can be normal in the beginning of each year.

It’s no coincidence that springtime in Greater New Orleans tends to be filled with the most outdoor activities and events each year. The pleasant temperatures each day, followed by very comfortable evenings, provide an ideal atmosphere for long hours enjoying the cultural riches of the region.

The summer months bring the most rainfall each year, averaging over 6 inches each month (bringing precipitation on more than 10 days per month), and highs in the low- to mid-90s. Most notably, hurricane season begins June 1, ending November 30.

Historically, October is the driest month, yielding an average of only 4 inches annually. Through the remainder of each year, average temperatures begin to drop to cool, sometimes cold, levels. Due to these comfortable temperatures, residents enjoy many annual festivals, sporting events, and other outdoor activities in the late months of the year.
