:. Louisiana Weather And Climate .:

Louisiana Weather is defined by long, hot, humid summers and short, mild winters. The Gulf of Mexico is most responsible for the tropical weather in Louisiana. Rain is frequent and sometimes severe, but snow is rare, with a couple of dustings hitting the north during a typical year. Few locations in the United States are warmer than Louisiana, especially when the effect of the high humidity is factored in. Temperatures in locations within a few miles of the Gulf are a little more moderate, in both summer and winter, than those inland, and temperatures in the North can exceed 105° in the summer and drop to 20° in the winter.


Hurricanes are a huge threat to Louisiana, as we tragically learned with Katrina. New Orleans is situated below sea level, and is more vulnerable to hurricanes than any city in the United States. The area is also prone to frequent thunderstorms, especially in the summer. Thunderstorms and tornadoes are also existing Louisiana weather threats.
