Weather & Climate

Southwest Louisiana’s climate is humid and sub-tropical with a strong maritime character. It is influenced to a large degree by the water conditions of the Gulf of Mexico. Rainfall, which is substantial in all seasons, averages more than 50 inches per year. In spite of the high rainfall amounts, dry spells of two to three weeks are not uncommon.


Spring and fall are very mild and pleasant seasons, with the summer consistently hot and humid. The winter months are relatively mild with cold spells usually of short duration. Snow is a rare form of precipitation. Outdoor activities are typically enjoyed year-round.
