San Antonio woke up soggy on Sunday, April 19, 2026, with wet skies and gusty east-northeast winds turning the morning drive into a slow crawl. Early readings showed light to moderate rain and temperatures in the low 50s, with conditions expected to trend drier across the city by late morning and a high near 70°F. Umbrellas are getting a workout and bridges and other exposed routes will feel especially blustery.
Rough Morning Ride: Wind And Rain Timing
Showers and a few thunderstorms are expected to hang around through about 10 a.m., then give way to mostly cloudy skies with east-northeast winds of 10 to 15 mph and gusts up to 30 mph. Light, lingering showers are most likely south of Highway 90, while the rest of the city sees only spotty rain through the afternoon. The National Weather Service advises drivers to watch for reduced visibility and slick roads during the morning commute, and to plan for extra travel time, especially near bridges and underpasses.
Monday And Tuesday Turn Wetter And Cooler
Rain and thunderstorms are expected to redevelop Sunday evening and become more widespread Monday, keeping daytime highs cooler, in the mid-60s Monday and back into the low 70s Tuesday. Some neighborhoods could see a quarter to a half inch of rain, with isolated heavier downpours that may top an inch in a few locations. That kind of soaking raises the risk of localized street flooding and thoroughly saturated yards. Anyone with outdoor plans on Monday or Tuesday should consider moving activities indoors or at least keep a close eye on updates and local advisories.
Fiesta Events Face Rain Clouds
Fiesta San Antonio runs April 16 to 26, and this week’s outdoor celebrations may have to dodge pockets of heavy rain and bursts of wind. Organizers and attendees can track changes using the official Fiesta San Antonio event calendar, and parade and picnic plans may need a little weatherproofing. Downtown and River Walk routes can turn slick quickly in downpours, so expect slower foot traffic and possible delays near major venues as crowds adjust to the showers.
Travel And Safety Basics In The Wet Weather
Drivers are urged to slow down on wet roads, avoid driving through standing water, and secure loose yard items before the wind kicks up. Residents in low-lying parts of the city should park on higher ground when heavier rain is in the forecast and keep phone alerts turned on for advisories. For those who must commute during the Monday morning rush, building in extra time or shifting schedules where possible could help avoid headaches from localized flooding or stalled traffic.
Later In The Week: From Soaked To Summerlike
By midweek the atmosphere is expected to dry out and warm up, with highs climbing into the mid-80s by Thursday and Friday as humidity returns. Before heading out, check updated forecasts and keep an eye on local warnings in case storms decide to make a return visit later in the week.
