Lake Charles, Louisiana – Life across Louisiana will slow to a crawl early next week as a dangerous wave of summer heat brings heat index values near 110 degrees from Sunday, July 13 through Tuesday, July 15. Public safety officials are urging residents to limit outdoor activity and protect vulnerable groups as temperatures surge to the highest levels of the season.
According to the National Weather Service in Lake Charles, an upper-level ridge building over the region will push heat risk to “major” and even “extreme” levels for parts of western and central Louisiana—including Lake Charles, Alexandria, Lafayette, Beaumont, and surrounding communities. Daily maximum heat index values are forecast to climb from 104°F on Sunday to as high as 109–110°F by Tuesday.
The most severe conditions are expected Monday and Tuesday, with impacts likely for health systems, utilities, and anyone working outdoors. High heat will especially endanger those without effective cooling or adequate hydration. Emergency managers warn of potential disruptions in heat-sensitive industries and infrastructure. Preparedness tips include staying indoors during peak afternoon hours, drinking plenty of fluids, checking on elderly neighbors, and never leaving children or pets in vehicles.
Residents in parishes along I-10 and I-49—including Calcasieu, Rapides, and Lafayette—should remain alert for additional heat advisories. Similar major heat events last occurred in 2023 and 2021, and each led to increases in heat-related illnesses and power outages.
Excessive heat warnings may be extended if conditions worsen. Further updates are expected as the event approaches.
