Alamo City Basks in Unseasonable February Warmth
A Spring-Like Tuesday for San Antonio
San Antonians can set aside their heavy winter coats today, Tuesday, February 17, 2026, as the region experiences a significant warming trend. While February often brings unpredictable cold snaps to Central Texas, today’s conditions feel more like a preview of late April. The Alamo City is expected to see plenty of sunshine throughout the day, with temperatures climbing well above seasonal averages.
Morning: A Crisp but Quick Warm-Up
The day began with clear skies and a refreshing start. Early morning temperatures hovered near 57°F, accompanied by high humidity levels around 94% to 97%. As the sun rose over the city, the initial dampness began to burn off, giving way to bright, golden conditions. Commuters enjoyed excellent visibility, though the high humidity may have caused some light, patchy fog in low-lying areas near the San Antonio River earlier this morning. By mid-morning, the mercury is already on a steady march upward.
Afternoon: Sunny Skies and Peak Temperatures
The highlight of the day will be the afternoon hours. San Antonio is on track to reach a high of approximately 82°F to 83°F. This peak heat is expected to hit between 3:00 PM and 5:00 PM. The National Weather Service reports that there are no active watches, warnings, or advisories in effect, making it an ideal day for outdoor activities or lunch on a patio. Winds will remain light and manageable, blowing from the south at roughly 8 to 10 mph. With a rain chance of nearly 0%, there is no need for umbrellas today.
Evening: Mild Conditions and Increasing Clouds
As we head into the evening, the clear skies will begin to shift. Forecasters predict that clouds will gradually increase overnight, leading to partly cloudy conditions by late Tuesday night. The evening will remain exceptionally mild for this time of year, with temperatures slowly dipping back into the 60s before settling at a low of approximately 56°F. Humidity will likely climb again after sunset, though no precipitation is expected to develop before Wednesday morning.
Looking Ahead
While today offers a warm reprieve, local meteorologists are keeping an eye on a cold front expected to arrive later this week. For now, residents should enjoy the unseasonable warmth. If you are planning to spend extended time outdoors this afternoon, remember that even in February, the Texas sun can be strong; light clothing and hydration are recommended.
