Alamo City Sizzle: Unseasonably Warm Skies Set for San Antonio Monday

A Spring-Like Surprise to Start the Week

San Antonio residents are waking up to a Monday that feels more like late April than mid-February. As we kick off today, February 16, 2026, the weather across the Alamo City is projected to be exceptionally pleasant, offering a significant reprieve from the typical winter chill. While the month of February usually sees average highs hovering around 68°F, today’s forecast suggests we will soar well past those historical norms, pushing into territory that might have you reaching for your sunglasses and lighter attire.

Morning: A Crisp and Clear Commute

The early morning hours in San Antonio will begin with clear skies and a few periodic clouds. Early risers can expect a cool start, with temperatures beginning in the upper 40s to low 50s. Humidity levels are currently high, sitting at approximately 86%, which may lead to some light, patchy morning mist in low-lying areas near the San Antonio River. However, as the sun rises, this moisture will quickly dissipate. By the time the morning rush hour concludes, the mercury will already be on a steady climb, making for a crisp but brightening start to the work week.

Afternoon: Peak Sunshine and Above-Average Highs

The highlight of today’s forecast is the afternoon period, where San Antonio is expected to hit a high of 78°F to 79°F. This unseasonably warm peak is nearly 10 degrees above the seasonal average. Skies will remain largely sunny throughout the midday hours, and the chance of precipitation is practically non-existent, staying at a mere 1%. Humidity is expected to drop to a more comfortable 54% by the afternoon, creating ideal conditions for outdoor lunches at the Pearl or a stroll along the River Walk. Winds will remain light to moderate, keeping the air moving without the threat of significant gusts.

Evening and Night: Increasing Clouds and Mild Conditions

As the sun sets, the city will see a shift in atmospheric conditions. While the daytime was dominated by sunshine, the evening will bring an increase in cloud cover, transitioning to a mostly cloudy night. Temperatures will remain relatively mild compared to previous weeks, only dipping to a low of approximately 57°F. There is a slight 10% chance of isolated showers late tonight, though most areas within the Loop 1604 corridor will remain dry. Humidity will begin to climb again overnight, signaling a more humid start for Tuesday.

Warnings and Travel Outlook

Currently, there are no active wind or rain warnings for the San Antonio metropolitan area. Fire weather risks remain low despite the warmth, thanks to the residual humidity from the morning. Commuters can expect dry roads and excellent visibility throughout the day. With such favorable conditions, today is designated as a 'comfortable weather day,' making it the perfect opportunity for outdoor activities before the potential for more active weather later in the week.
