Monday, February 9, 2026 is serving up a little weather whiplash in San Antonio. The day kicked off clear and cool, with temperatures hovering around 51°F at local stations, but that early chill will not last. Southerly flow is set to crank afternoon highs into the low 80s, giving the city a springlike feel in the middle of February. Before you get too comfortable, though, the morning commute could feature pockets of fog, and small rain chances creep back in later this week.
Morning Fog And Week Ahead
Patchy to locally dense fog is possible across the Coastal Plains and areas east of I-35 through mid-morning, with visibility dropping to a quarter mile or less in spots. If you drive into one of those thicker patches, ease off the gas and flip on the low beams to keep things safe. Once the fog lifts, the rest of Monday looks sunny and warm, with a high near 83°F. Tuesday, February 10, 2026 should top out near 76°F, and Wednesday, February 11, 2026 is expected to reach around 78°F.
A weak system brings a 20 to 30 percent chance of showers Tuesday night into early Wednesday, just enough to put a few raindrops on the radar. Another round of showers and isolated storms may arrive late Friday into Saturday, with rain chances climbing to roughly 40 percent. According to the National Weather Service Austin/San Antonio, there are no watches or warnings in effect at this time.
Plan Ahead
Plan on a slower-than-usual morning drive today if you are in the fog-prone zones, and dress in layers so you are not roasting once the afternoon heat settles in. Outdoor plans may be more comfortable shifted toward mid-afternoon, when temperatures peak. Nights remain cool enough that pets and sensitive plants could use a bit of protection, but days are warm enough that you will want water and sunscreen on hand while this pattern hangs on.
