Houston starts Sunday, March 15, 2026 on a mostly clear and mild note, with early morning temperatures hovering around 66°F. It will feel like a classic warm spring afternoon with highs near 83°F, but the calm vibe does not last long. By late morning, strengthening winds become the main thing to watch if you have outdoor plans.
Afternoon Winds Pick Up
South winds are expected to ramp up to 10–15 mph Sunday afternoon, with gusts potentially reaching 30 mph by mid to late afternoon. A Wind Advisory is in effect from 10 AM CDT on Sunday, March 15, 2026 through 6 PM CDT on Monday, March 16, 2026. Those kinds of gusts can make driving tricky for high-profile vehicles and can easily fling around unsecured items, so think ahead about patio furniture, lawn décor, and trash cans.

Evening Front Could Bring Brief Storms
A fast-moving cold front charges in late Sunday afternoon into the evening, with a roughly 7–10 p.m. window when showers and isolated thunderstorms are most likely. Some storms along the front could produce damaging wind gusts and small hail, although overall rainfall totals are expected to stay on the low side.
Once the front passes, temperatures drop quickly. Lows Sunday night slide into the mid-40s, and Monday turns sharply cooler, with afternoon highs only in the mid-50s.
Fire Weather Watch And Coastal Hazards
Forecasters have issued a Fire Weather Watch for Monday, March 16, 2026, as dry air and brisk northerly winds team up. Relative humidity may fall into the upper teens and low 20s while wind gusts run in the 25–35 mph range, which can support rapid fire spread if a blaze gets started.
On the water, conditions take a rough turn. Mariners should be ready for hazardous seas and gale-force gusts Sunday night into Monday, and rip currents may increase along Gulf beaches; avoid sending small craft out and check local beach flags and advisories before heading to the coast.
Plan Ahead
It is a good day to secure loose outdoor items, give extra room and attention when driving high-profile vehicles, and hold off on any open burning until winds and humidity improve. For more on the broader storm setup that led to this pattern, see our earlier coverage: Storms, Fog and Flood Fears.
