The Climate of Louisiana

By | August 27, 2022

According to Abbreviation Finder, the US state of Louisiana (LA) is located in the southeastern United States. Louisiana is located on the Gulf of Mexico and borders the states of Arkansas, Mississippi, and Texas. The border with Mississippi is partly formed by the river of the same name. Louisiana is a fairly flat state, with no serious elevations. Louisiana’s highest point is just 163 feet above sea level. On the coast dominate swamp areas, which in total account for an area of ​​no less than fifty thousand square kilometers.

Warm maritime climate

Louisiana has a warm maritime climate, which falls within the Köppen classification in the Cfa category. Of all US states, Louisiana is perhaps the most classic example of this climate type. The subtropical character is mainly determined by its location on the Gulf of Mexico, which ensures that the winters are very mild and there are very warm and humid summers. From May to September, the maximum temperature is on average between 30 and 35 degrees Celsius. Precipitation is fairly evenly distributed throughout the year, with summers being slightly wetter than other seasons.


Louisiana is vulnerable to hurricanes and tropical storms, which can move north from the Gulf of Mexico to Louisiana from July through December. Because part of Louisiana’s coastal area is just above or even below sea level, the probability of flooding from hurricanes is quite high. The history of Louisiana therefore unfortunately has several lows in this area, such as Hurricane Katrina, which in August 2005 caused as much as 80% of the city of New Orleans to be flooded. The economic and social damage was enormous, especially as many residents became homeless in one fell swoop.
