Louisiana experiences very hot and humid summers, with temperatures frequently reaching the upper 80s to mid-90s Fahrenheit (around 30-35°C). The combination of high heat and humidity often results in a heat index that feels even hotter, sometimes exceeding 100°F (38°C). Coastal cities like New Orleans and Baton Rouge are especially known for their muggy summer conditions.
The state's subtropical climate means that summer humidity levels are consistently high, often ranging from 70% to 90%. This humidity is due to Louisiana’s proximity to the Gulf of Mexico, which provides a steady source of moisture. Afternoon thunderstorms are common during the summer months, offering temporary relief from the heat but maintaining the overall humid atmosphere. Residents and visitors should be prepared for intense heat and take precautions against heat-related illnesses.
