New Orleans is waking up to a bright, muggy start Friday, June 26, 2026, with clear skies and temperatures already near 81°F as of 5:35 a.m. CDT. Humidity is sitting around 84%, so the air feels thick, and a south-southwest breeze is showing up at local stations. The rest of the day will be mostly sunny with a high near 93°F and heat index values climbing into the low to mid 100s during the hottest hours. Keep water handy and try to avoid strenuous outdoor activity in the midafternoon.
Afternoon Heat
Sunny skies will rule the day Friday with generally light south winds and only a small chance of a stray shower. The worst of the heat is expected between roughly 1 p.m. and 4 p.m., when conditions will feel most oppressive.
Weekend And Early Workweek
Heat will keep building through the weekend and into Monday, with heat index readings possibly topping 108°F starting Sunday, June 28, 2026. The National Weather Service warns that heat advisories are increasingly likely for parts of southeast Louisiana and southern Mississippi as the weekend wears on, so residents should be ready for extended stretches of uncomfortable conditions and plan to limit outdoor exertion.
Midweek Storm Risk
By Tuesday and Wednesday (June 30 to July 1) deeper Gulf moisture and an easterly flow will raise the odds of showers and thunderstorms. Forecasters caution that any stronger storms could bring heavy downpours, gusty winds and localized flash flooding, especially where storms train over the same area or stall out.
Where To Cool Off
For people without reliable air conditioning, the city’s NOLA Ready Heat Relief map lists cooling centers, libraries and recreation centers that open during heat events. Call 311 or check the NOLA Ready site for current hours and locations.
Quick Safety Tips
Drink plenty of water, pace outdoor chores and check on older neighbors, young children and pets. If someone shows signs of heat exhaustion such as fainting, heavy sweating, dizziness or confusion, move them to a cool place and seek medical help right away.
