New Orleans woke up muggy on Monday, June 22, 2026, with clear skies, mid-morning temperatures already around 81°F and humidity turning the air into a wet blanket. Heat will keep cranking up through the afternoon, with a high near 92°F and heat index values expected to spike into the 105–109°F range. A Heat Advisory is in effect from 10 AM to 8 PM CDT, so anyone planning to be outside during peak hours should expect it to feel downright punishing.
Afternoon Heat And Short-Range Outlook
The Heat Advisory running from 10 AM to 8 PM CDT on Monday warns that the combination of hot temperatures and high humidity will push “feels like” readings into the dangerous zone this afternoon. Forecasters are calling for mostly sunny skies, light southwest winds around 5–10 mph, and only a small chance of rain today. Scattered afternoon thunderstorms are more likely to pop back up by Wednesday, June 24, with the potential for brief heavy downpours and gusty winds, according to the National Weather Service New Orleans.
Where To Cool Off And What To Do
If you need air conditioning, the city’s NOLA Ready Heat Relief Map lists daytime cooling sites and library hours. Common daytime options include the Andrew P. Sanchez & Copelin-Byrd Multi-Service Center at 1616 Fats Domino Ave, along with public pools and rec centers that are operating with extended hours. Keep water with you, limit strenuous activity between about 10 AM and 6 PM, and never leave children or pets in parked cars. It is also a good day to check on older neighbors and anyone managing health conditions.
Quick Safety Tips
If you have outdoor plans this week, try to move heavy work to early morning or evening and take frequent breaks in the shade. Watch for signs of heat illness such as dizziness, headache, nausea or confusion, and get to a cool, shaded or air-conditioned space if any of those symptoms show up.
