Houston woke up under a low lid of clouds and sticky air on Tuesday, March 3, 2026, with downtown temperatures hovering near 70°F and pockets of sea fog creeping in from the Gulf. Visibility has dropped sharply along the coast and near Galveston Bay, so morning commutes and ferry runs may move at a crawl.
Foggy Mornings, Sunny Afternoons
Dense fog built in overnight across the lower bays and nearshore waters, with Scholes Field near Galveston reporting roughly a half-mile visibility around midnight. A Dense Fog Advisory is in effect into mid-morning, according to the National Weather Service Houston-Galveston. Any fog that drifts inland should thin out by late morning, with skies turning partly sunny while humidity stays stubbornly high through the afternoon.
Afternoon Winds Pick Up
Southeast winds are expected to pick up this afternoon to about 5-15 mph, with gusts up to 25 mph, so it will feel breezier than the numbers alone suggest. Highs should climb into the low 80s away from the immediate coast, with mid 70s likely at Galveston, which is unseasonably warm for early March.
Weekend Rain Risk
A few spotty showers could pop up on Wednesday, but the better shot at wet weather arrives Saturday into Sunday. Forecasters say showers and thunderstorms could bring locally heavy rain where storms repeatedly pass over the same area, according to the National Weather Service Houston-Galveston. If you have outdoor plans this weekend, keep an eye on the forecast, since brief flooding is possible in low-lying or poorly drained spots.
Commute And Marine Tips
If you are driving near bayous or heading for ferry terminals this morning, leave extra time, use low-beam headlights and ease off the gas when visibility suddenly drops. Boaters should consider holding off on nonessential departures until mid-morning and keep up with local marine advisories.
