San Antonio residents are in for a wild ride this week as the weather swings from damp, drizzly mornings to near-summer warmth before a sudden blast of cold air moves in. Whether you’re dressing for morning rain, soaking up the sun, or bracing for cooler nights, this week will have you checking the forecast more often than usual.
Day-by-Day Breakdown of San Antonio’s Weather
Tuesday:
A little relief from the gloom as the clouds break apart and the sun peeks through. Temperatures will rise to 65°F (18°C), making it a pleasant day to spend time outdoors. At night, temperatures will settle around 56°F (14°C). It’s a comfortable day, but changes are brewing.
Wednesday:
Here comes the heat! Temperatures will soar to a balmy 84°F (29°C)—a tie with the record high set back in 2017. Don’t be surprised if it feels like a mini-summer day. But by night, everything changes. A cold front will sweep in, dropping the temperature to 43°F (6°C). Enjoy the warmth while it lasts, because Thursday will be a different story.
Thursday:
The cold front takes full control. Daytime highs will only reach 50°F (10°C), and the night will be chilly with lows around 42°F (5°C). Gusty winds and overcast skies will make it feel even colder. It’s a dramatic shift from Wednesday’s heat, so make sure you’ve got a jacket ready.
Friday:
A mix of clouds and sunshine will bring slightly warmer conditions, with the high reaching 56°F (13°C). The low will be around 52°F (11°C). It’s not exactly toasty, but it’s a good middle ground before things warm back up again.
Saturday:
Spring-like warmth returns with a high of 77°F (25°C). As the day progresses, clouds will clear out, leaving sunny skies for much of the afternoon. But don’t get too comfortable—the low will drop sharply to 40°F (5°C) overnight. Make the most of the sunshine during the day before cooler air moves back in.
Sunday:
A cooler, breezy end to the week. Highs will hover around 59°F (15°C), and strong winds will make it feel even cooler. The low will dip to 31°F (0°C) at night, so you’ll definitely want a jacket if you’re heading out.
What’s Causing These Temperature Swings?
San Antonio’s rapid weather changes this week are being driven by shifting air masses and an active cold front. Early in the week, moisture from the Gulf of Mexico is keeping things cool and cloudy. But by midweek, warm air surging from the south will bring temperatures soaring into the 80s. That warmth won’t last long, though. A cold front moving in Wednesday night will cause a sharp drop in temperatures, leaving San Antonio feeling chilly through the weekend.
Why You Should Be Prepared:
This week’s changing weather could catch you off guard if you’re not paying attention. Here’s why you need to stay ready:
- Drizzle Can Create Slippery Roads: The light rain on Monday might not seem like much, but it can make roads slick, especially during morning commutes. Drive carefully.
- Rapid Temperature Drops: Going from 84°F one day to 50°F the next is no joke. Dress in layers so you can adjust to the changing temperatures.
- Gusty Winds on Thursday: Winds could make Thursday feel even colder, especially in the morning.
- Weekend Plans Could Be Affected: Saturday will be warm and sunny, but by Sunday night, temperatures will dip to near freezing. If you’re planning outdoor activities, be sure to check the forecast.
- Cold Nights Mean Heating Up: With nighttime lows dropping as low as 31°F on Sunday, make sure your home heating is ready.
Tips to Get Through the Week Comfortably:
- Layer Up: The temperature changes will be noticeable, so wearing layers will help you stay comfortable as the weather shifts throughout the day.
- Keep an Eye on the Sky: Drizzle on Monday, sunshine on Tuesday, and gusty winds on Thursday mean you’ll want to check the forecast before stepping out.
- Stay Hydrated: With temperatures nearing 80°F on Wednesday, make sure you’re drinking enough water, especially if you’re outside.
- Be Prepared for Sunday Night’s Cold: Bring in any outdoor plants or pets that may be sensitive to freezing temperatures.
