ALEXANDRIA, La. (KALB) - Louisiana, along with the rest of the southeastern states in the United States, are situated close to the Gulf of Mexico. With that being said, the state’s climate is influenced by its close location to the Gulf of Mexico and having a subtropical latitude, lying roughly between latitudes of 29 and 33 degrees north.

The Gulf of Mexico water temperatures are warm throughout the year and they range from roughly 64 degrees Fahrenheit in the wintertime to 84 degrees in the summertime. When we get the south winds coming from the Gulf into the state of Louisiana, that’s what leads to warm and muggy air. In the summertime, this pattern leads to popcorn afternoon thunderstorms.

In general, whenever you get a south wind that brings in warmer air; meanwhile, whenever you get a north wind that brings in cooler air. These southerly winds that occur throughout the year in the state of Louisiana lead to increased levels of overall humidity. In the summertime across Louisiana, the summers are hot and humid. The humidity is thanks to the southerly flow from the Gulf of Mexico.

The warm and muggy air out of the Gulf of Mexico in the summertime results in daily doses of showers, especially in coastal Louisiana. The farther north you go across Louisiana, the less frequent showers occur. In the summer, these showers and thunderstorms typically occur during the peak of daytime heating hours. Also, the Gulf of Mexico pulls in tons of moisture into Louisiana when the southerly flow is in full force.
