New Orleans woke up sticky and steamy on Tuesday, June 30, 2026, with KNEW clocking in around 82°F (28°C) and humidity hovering near 79 percent at 5:35 a.m. CDT. It only gets hotter from here, with forecasters calling for afternoon highs near 95°F and heat index readings pushing into the 105 to 110°F range. A Heat Advisory is in place from 11 a.m. to 6 p.m. CDT, so anyone working or exercising outside is urged to slow down and take it seriously.
Afternoon Heat and Safety
The National Weather Service has issued a Heat Advisory for much of southeast Louisiana, warning that heat index values could reach 110°F this afternoon. The advisory runs from 11 a.m. to 6 p.m. CDT, according to NWS New Orleans. The guidance is simple but crucial: drink plenty of fluids, stay in air-conditioned spaces when you can, and avoid strenuous activity in the middle of the day. Employers and event organizers are urged to push heavy work to the early morning or evening hours and to make sure there is shade and water on hand.
Storms Return Tonight and Wednesday
Today is dominated by heat, but relief may start to sneak in later. A slight chance of showers and thunderstorms develops this evening, mainly after 7 p.m., with a better shot at rain on Wednesday. The midweek forecast shows the highest rain chances and the potential for scattered storms. Widespread severe weather is not expected, although a few storms could produce strong downbursts, gusty winds, or pockets of locally heavy rain. If you have outdoor plans, keep an eye on the radar, since storms could move in quickly and briefly knock down visibility.
Where To Find Cooling
Residents without reliable air conditioning are not completely on their own. The city maintains a Heat Relief map and operates cooling centers and hydration stations during heat events. Check NOLA Ready for up-to-date locations and hours. You can also call 3-1-1 to ask for assistance or to report someone who may need shelter. Public libraries and NORDC recreation centers often serve as daytime cooling spots when the heat cranks up.
What To Do Now
Keep water with you, wear light, breathable clothing, and take frequent breaks if you have to be outside this afternoon. Keep a close eye on children, older adults, and pets, and never leave anyone in a parked car, even for a short time. Seek medical help right away if you spot signs of heat exhaustion or heat stroke. The pattern does not break immediately, with temperatures staying uncomfortably hot through the week and rain and storm chances climbing by midweek.
