Alamo City Sizzles: San Antonio Braces for Record-Breaking February Heat

Historic Heat Wave Grips San Antonio

San Antonio residents are waking up to a weather pattern that feels more like the peak of spring than the tail end of February. Today, Thursday, February 26, 2026, the Alamo City is positioned to challenge or even shatter a temperature record that has stood for 72 years. Meteorologists have labeled today an 'Impact Day' due to unseasonably high temperatures and critical fire conditions across the region.

Morning: A Rapid Climb

The day began comfortably with temperatures in the mid-to-upper 50s and low 60s under mostly clear skies. However, this morning chill is fleeting. Thanks to exceptionally dry air and intense sunshine, the mercury is expected to rise with unusual speed. By 11:00 a.m., temperatures are forecasted to hit the 80-degree mark, and by noon, San Antonio will likely see readings in the mid-80s. Residents are encouraged to complete outdoor chores early before the afternoon heat peaks.

Afternoon: Chasing the 1954 Record

The core of the heat will arrive between 2:00 p.m. and 5:00 p.m. Forecasts indicate that afternoon highs will reach between 91 and 94 degrees. This puts the city directly in competition with the all-time record for February 26, which was 91 degrees set back in 1954. Some localized weather models suggest that certain areas of the metro could even briefly touch 98 degrees if the dry southwesterly winds from northern Mexico intensify. Humidity levels will drop significantly as the afternoon progresses, falling as low as 13% to 33%.

Evening: Clear Skies and Cooling Down

As the sun sets, the lack of cloud cover will allow for a gradual cooldown. Temperatures will descend through the 80s and 70s during the early evening hours, eventually settling into the low 60s overnight. While the evening will be pleasant, the atmosphere remains very dry, providing little relief from the day's parching conditions.

Wind and Fire Safety Warnings

While the heat is the primary story, wind and fire safety are the primary concerns for local officials. The following conditions and warnings are in effect for today:

• Fire Danger: A high fire danger alert is active for Bexar County. A Red Flag Warning has been issued for the Hill Country and communities immediately north and west of San Antonio from 11:00 a.m. to 7:00 p.m.
• Wind Conditions: Expect northerly winds between 10 to 15 mph, with gusts reaching up to 25 mph. These breezy conditions, combined with the extreme heat and low humidity, create a high risk for fast-spreading wildfires.
• Precipitation: There is a 0% chance of rain for the entire day.

Residents are advised to avoid any outdoor burning, ensure cigarette butts are disposed of properly, and avoid parking vehicles on dry grass to prevent accidental ignitions.
