New Orleans rolled out of bed Wednesday, March 3, 2026, to a wall of fog that chopped visibility down to roughly a quarter mile near the Lakefront, with temperatures hovering around 61°F. A warm, sticky flow off the Gulf is to blame, serving up muggy, hazy mornings before the sun muscles through by late morning and sends highs into the upper 70s. Early commuters should be ready for slower-going on bridges, low-lying roads and along the lakefront, where pockets of dense fog can drop visibility in a hurry.
Dense Fog Advisory and Morning Travel
The National Weather Service has a Dense Fog Advisory in effect until 9:00 AM CST Wednesday, March 3, 2026, after visibility dropped to about one quarter mile in spots. Forecasters are calling for highs near 79°F with light southeast winds and warm, humid nights that will favor more fog redeveloping through at least Thursday night. Drivers are urged to use low-beam headlights, ease off the gas and leave extra room to stop, since the advisory notes that low visibility could make travel hazardous, according to NWS New Orleans.
Afternoons Warm, Nights Foggy
The sun is expected to break through later this morning, setting up afternoons in the upper 70s to near 80°F, while nights stay mild and sticky. Isolated afternoon showers could pop up later in the week, but the main repeat act will be nightly fog and pockets of sea fog near lakes and riverbanks through the weekend.

Boaters, Bridges and What To Do
Sea fog forming over cooler nearshore waters can drift inland and cause navigation headaches for small craft and anyone heading to marinas at first light. Boaters should hold off on nonessential trips and check the latest marine forecasts, while drivers should skip cruise control, stick with low beams and budget extra time for early-morning travel. The Dense Fog Advisory is scheduled to expire at 9:00 AM CST, but stubborn fog patches may hang on into mid-morning near the lake and along the river.
