Water Temperature in Louisiana: General Trends and Swimming Opportunities

In Louisiana, the water temperatures along the coastline are influenced by the Gulf of Mexico, which provides relatively warm waters throughout the year. During the summer months, water temperatures in the Gulf off Louisiana's coast can reach between 80°F and 88°F (27°C to 31°C), making it a popular destination for swimming, fishing, and other water sports. The warm waters attract tourists to areas like New Orleans and the Gulf Coast, where the high temperatures are ideal for beachgoers and boating enthusiasts. These warm waters also support a diverse range of marine life, from shrimp and fish to dolphins.

As the cooler months arrive, the water temperatures along Louisiana’s coast begin to decrease, typically dropping to around 60°F to 70°F (15°C to 21°C) during the fall and winter months. While the temperatures remain relatively mild compared to other regions of the U.S., the change is noticeable, especially for those used to the warmer summer conditions. Despite the cooler water, the Gulf remains a popular destination for winter fishing, with anglers targeting species such as redfish, trout, and flounder.

In Louisiana's rivers and lakes, temperatures tend to vary more depending on the location and season. During the summer, rivers like the Mississippi and Red River can see water temperatures reaching around 70°F to 85°F (21°C to 29°C), making them suitable for a variety of water activities like canoeing, kayaking, and fishing. Lakes such as Lake Pontchartrain and Lake Maurepas also experience warmer waters in the summer, with temperatures similar to those of the rivers. As fall and winter approach, the water temperatures in rivers and lakes gradually drop, with winter water temperatures ranging from 50°F to 65°F (10°C to 18°C). These cooler conditions make it less favorable for swimming, but the drop in temperature signals the start of prime fishing season for species that prefer cooler waters, like bass and catfish.
