Seasonal Precipitation Patterns

New Orleans experiences a subtropical climate characterized by abundant precipitation throughout the year. The city’s wettest months are typically June through October, coinciding with the hurricane season. During this period, warm, humid air from the Gulf of Mexico rises and condenses, leading to frequent thunderstorms and heavy rainfall. In the summer months, average monthly rainfall can exceed 150 millimeters (6 inches).

Annual Precipitation and Extreme Events

New Orleans receives an average annual precipitation of approximately 1,520 millimeters (60 inches). However, rainfall can vary significantly from year to year. Occasionally, the city experiences severe droughts or extreme rainfall events. For example, in 2005, Hurricane Katrina brought record-breaking rainfall to New Orleans, causing catastrophic flooding and widespread damage. The city also faces challenges from sea-level rise, which exacerbates the effects of storm surges and flooding during intense rainfall events.

Rainfall Patterns

New Orleans experiences a subtropical climate characterized by abundant rainfall throughout the year. The city receives an average of 60 inches of precipitation annually, with the wettest months being May through August.

However, during exceptional weather events, such as the December 2008 cold front, temperatures in New Orleans can drop significantly, leading to snowfall. In 2008, a combination of a polar vortex and a low-pressure system brought icy conditions to the Gulf Coast, resulting in snowfall across southern Louisiana, including New Orleans. While the snow melted quickly due to the warmer ground temperatures, the event was a memorable one for residents unaccustomed to winter weather.
