Houston woke up Saturday, June 13, 2026, to a classic Gulf Coast combo: mostly clear skies, thick humidity and temperatures already hovering near 79°F, with dewpoints stuck in the mid 70s. It will feel every bit like summer across the Bayou City today, with highs headed for the low to mid 90s and an afternoon that will be downright sticky.
Afternoon Heat And Storm Chances
Through the afternoon, expect plenty of sun with just a slight chance of showers or a brief thunderstorm developing after about 11 a.m. Forecasters are calling for highs near 94°F, with light southeast winds occasionally gusting up to 20 mph. Heat index values could push into the low triple digits later today, according to NWS Houston/Galveston.
Cooling Centers And Heat Safety
For anyone who needs a place to cool off, Houston libraries, community centers and some multi service centers can serve as cooling spots. Call 3-1-1 to find the nearest location or to request transportation. Stick with the basics: drink plenty of water, avoid heavy outdoor work during the midday peak, and check on neighbors, pets and anyone especially vulnerable to heat. The City of Houston Health Department shares guidance on cooling center availability and heat precautions.
Sunday Night Into Tuesday: Heavy Rain, Rip Currents And Coastal Flooding
A front sliding into Southeast Texas late Sunday is expected to crank up the rain chances, with heavier showers and thunderstorms likely from Sunday night into Monday and lingering into Tuesday. Widespread totals of 1 to 3 inches are possible, with isolated pockets near 5 inches that could trigger flash flooding in low lying urban spots. Along the coast, a high rip current risk runs through Monday morning, and a Coastal Flood Advisory is in place for parts of the Gulf shoreline from 1 a.m. to 1 p.m. Sunday, with minor overwash possible at high tide. Stay on top of watches and warnings and avoid driving through standing water, per NWS Houston/Galveston.
Quick Takeaways
Plan outdoor chores for early morning or evening and bring water if you will be outside for a while. Beach plans might need a rethink: swim only near a lifeguard while the rip current risk is high, or postpone your trip. If you do get caught in a rip current, float and signal for help. Keep an eye on local alerts and call 3-1-1 for city cooling resources if you need a safe, air-conditioned spot.
