San Antonio weather today brings mostly cloudy skies with a high near 75°F and northeast winds gusting up to 25 mph—a pleasant spring day perfect for getting outside after a cool front moved through Wednesday evening.

The National Weather Service notes that Thursday will be noticeably cooler than recent days, with the northeast wind keeping temperatures moderate throughout the afternoon. Rain chances are minimal today at just 10%, so outdoor plans around the River Walk, Brackenridge Park, or your favorite Hill Country spot should stay dry.

Today’s Setup

A cold front has already pushed through, and today’s northeast winds at 10 to 15 mph with gusts as high as 25 mph will keep things breezy. Clouds will be stubborn—the National Weather Service forecast discussion indicates that mid-level southwesterly flow aloft combined with the frontal boundary will make it hard for clouds to break up. Don’t expect much sunshine, but that’s actually a blessing if you’re sensitive to spring allergens. If you’re dealing with allergies, Claritin non-drowsy allergy relief can help you enjoy the day comfortably.

Best Window To Be Outside

This afternoon between 11 AM and 4 PM CT is your sweet spot. Winds will be steady but manageable, and temperatures will hover in the low to mid-70s. If you’ve been itching to get out on the water or hit the links, today’s a solid fishing and golf window before the weekend’s rain chances increase. Check out our guide on the best golf balls for high handicappers if you’re planning a round at one of the local courses.

Tonight & Tomorrow’s Shift

Tonight stays mostly cloudy with a low around 67°F and calmer winds (5-10 mph from the ENE). Friday is when things get more interesting: a 40% chance of showers and thunderstorms develops as a mid-level shortwave moves east. The National Weather Service has placed a Slight Risk (Level 2 of 4) for excessive rainfall across the I-35 Corridor and Coastal Plains Friday morning through early Saturday morning, with potential for locally heavy rainfall. Stay weather-aware Friday if you’re planning outdoor activities.

What To Wear & Bring

Today calls for layers—a light jacket or long-sleeve shirt for the breeze, but nothing heavy. Sunglasses and a hat will help if you’re heading to the Frost Bank Center or catching outdoor activities. If you’re grilling tonight, the winds mean you’ll want to anchor any outdoor setup; a pop-up canopy tent with weights is ideal for keeping things stable on breezy days.

Grilling & Meal Ideas

Today’s mild, dry conditions are perfect for firing up the grill. Throw on burgers, steaks, or grilled chicken with corn on the cob—the steady northeast breeze will help keep smoke moving and temperatures comfortable. Grab an instant-read meat thermometer and a grill brush and scraper set to make sure everything cooks perfectly. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Spurs Playoff Watch

If you’re heading to the Spurs Round 2 Game 5 against the Timberwolves on May 12 at the Frost Bank Center, expect pleasant conditions by then—though Friday’s storms will have moved through. Tailgating weather next Tuesday will be much more favorable than the rainy weekend. Grab Official team gear on Fanatics to show your support.

Next Few Days

Friday brings that 40% chance of showers and thunderstorms with a high near 79°F. Friday night, chances increase to 60% as showers and thunderstorms become likely. The National Weather Service forecast discussion emphasizes that efficient warm rain processes could lead to localized heavy rainfall, particularly over the I-35 Corridor and Coastal Plains. Weekend clearing and drying is expected by Sunday, with a return to more typical spring weather. Stay tuned for updates as Friday approaches.
