Unseasonable Heat Hits the Alamo City: San Antonio Braces for Record-Breaking Warmth Today
A Spring Preview in February
San Antonio residents can trade their heavy coats for short sleeves this Monday, February 9, 2026, as the region experiences a dramatic and unseasonable warm-up. While February typically brings a mix of crisp mornings and mild afternoons, today's forecast suggests a heatwave more characteristic of late April or early May. Temperatures are expected to soar nearly 20 degrees above the historical average, making it one of the warmest February days in recent memory.
Morning Conditions: A Crisp Start to a Rapid Climb
The day began with relatively mild conditions for early February. Early risers saw thermometer readings in the mid-50s, specifically around 54°F to 56°F. However, don't let the morning coolness fool you. With clear skies and light southerly winds already in place, the mercury is set to rise rapidly. By 10:00 AM, temperatures will likely already be in the upper 60s, transitioning quickly into a very warm midday period.
Afternoon Outlook: Approaching the Mid-80s
The peak of today's heat will occur between 3:00 PM and 5:00 PM. Forecasters are predicting a high of 82°F to 84°F across the San Antonio metro area. Under partly sunny skies, the "feels like" temperature may reach 80°F or higher due to a slight increase in humidity, which is expected to hover around 50% during the heat of the day. South winds will remain steady but gentle, averaging about 8 mph, providing only minimal relief from the afternoon sun.
Evening and Overnight Forecast
As the sun sets, the clear skies will begin to give way to increasing cloud cover. Evening temperatures will remain quite comfortable, slowly dipping into the low 70s and eventually settling at an overnight low of 61°F. While the daytime remains dry, the National Weather Service indicates a slight shift in the pattern as we head into Tuesday. The cloud cover tonight will act as a thermal blanket, keeping the city significantly warmer than the usual 44°F lows seen this time of year.
Rain Chances and Weather Alerts
For those concerned about precipitation, the day looks mostly clear with only a nominal 5% chance of a stray shower during the afternoon. However, moisture levels will rise overnight, bringing a 10% chance of light rain by early Tuesday morning. Currently, there are no active wind or rain warnings for the Bexar County area, and no severe weather is anticipated. Residents are encouraged to stay hydrated and enjoy the sunshine before a more unsettled weather pattern arrives later in the week.
