Sun-Drenched and Breezy: Wildfire Risks Rise as San Antonio Warms Up

A Shift Toward Spring-Like Warmth

San Antonio residents can expect a significant shift in the atmosphere this Tuesday, February 24, 2026, as a ridge of high pressure settles over South Texas. While the early morning hours may still carry a lingering chill from the weekend, the afternoon is set to deliver a surge of warmth that pushes temperatures well above the seasonal average. However, with this beautiful sunshine comes a critical warning regarding dry conditions and elevated fire risks across the region.

Morning: A Crisp and Clear Start

The day begins with clear, star-studded skies and crisp air. Morning commuters will want to keep a light jacket or sweater handy, as temperatures at sunrise are expected to hover in the mid-40s. While some low-lying areas in the surrounding Hill Country may flirt with near-freezing temperatures, San Antonio proper will remain safely above the frost line. As the sun rises, the atmosphere will stabilize quickly, leading to a rapid warm-up through the mid-morning hours.

Afternoon: Peak Warmth and Breezy Conditions

By the afternoon, the Alamo City will feel more like late March than late February. High temperatures are forecasted to reach a pleasant 75°F, driven by abundant sunshine and a shift in wind direction. South to southwest winds will pick up speed, sustained between 8 and 15 mph. Localized gusts could reach as high as 25 mph, making for a breezy afternoon. These winds are pulling in warmer air, but they are also contributing to a significant drop in relative humidity.

Evening: Pleasant Skies and Nighttime Cooling

As the sun sets, the winds will begin to taper off, though a light breeze will persist. The evening will be exceptionally clear, making it a perfect night for outdoor dining or stargazing. Temperatures will gradually descend into the 50s by late evening, eventually settling at a comfortable overnight low of approximately 54°F. No cloud cover is expected to move in, ensuring a bright moonlit night.

Critical Safety Notice: Wildfire Risk

While the weather is ideal for outdoor activities, the National Weather Service and local officials are urging extreme caution. Due to the combination of dry vegetation, low humidity—dropping as low as 10% in some pockets—and breezy afternoon gusts, there is an elevated risk for wildfires. Residents should take note of the following:

• Burn bans remain in full effect for San Antonio and surrounding Bexar County.
• Avoid any outdoor activities that could produce sparks, such as welding or using grinding tools in grassy areas.
• Ensure that all cigarette butts are disposed of in proper containers, never thrown from vehicle windows.
• Keep vehicles off dry grass, as hot exhaust pipes can easily ignite parched brush.

With no rain in the immediate forecast, the region remains in a dry spell that is expected to last through the end of the month. Stay hydrated and stay fire-aware as you enjoy this taste of early spring.
