New Orleans is waking up under clear skies and a muggy 73°F at the KNEW station this morning (Tuesday, April 28, 2026), with a dew point near 72°F and relative humidity in the mid-90s. The air is already sticky, so that early dog walk, jog or trash run is going to feel warmer than the thermometer suggests.
Afternoon Heat And Humidity
Mostly sunny skies will nudge highs to about 86°F today (Tuesday, April 28, 2026), then to around 87°F on Wednesday, April 29, 2026, with southeast winds of 5 to 15 mph. Thanks to stubborn humidity, heat index values are expected to climb into the mid to upper 90s during the hottest part of the afternoon, which will crank up heat stress for outdoor workers, delivery drivers and anyone squeezing in a workout outside. Forecasters at the National Weather Service recommend staying hydrated and dialing back strenuous activity during mid-afternoon hours.
