San Antonio, TX – March 13, 2025 – Get ready, San Antonio—spring is coming in hot! Today, temperatures are expected to soar past 90°F (32°C), making it the first official 90-degree day of the year. But with this heat comes serious concerns—a Red Flag Warning is in effect, meaning wildfire risks are dangerously high due to gusty winds and extremely dry conditions.
What’s Going On?
San Antonio’s weather is turning up the heat, quite literally. Normally in March, we’d be enjoying highs around 74°F (23°C), but this week’s temperatures are anything but normal. If we hit 93°F (34°C) today, we could match a record set back in 1971!
Your San Antonio Forecast
- Thursday, March 13: Blazing sunshine and gusty winds up to 30 mph. High of 90-93°F (32-34°C) and a mild evening at 63°F (17°C). Fire danger is at its highest today—avoid any outdoor burning!
- Friday, March 14: A weak cold front moves in, cooling things slightly to 87°F (31°C), but still warmer than average. Winds will pick up, making fire risks even more critical.
- Saturday, March 15: Highs drop to 80°F (27°C), but extreme drought conditions continue. Rain remains unlikely, and dry vegetation keeps wildfire concerns alive.
Why the Red Flag Warning Matters
San Antonio has been bone-dry for weeks, and with low humidity and strong winds, any spark could ignite a fast-moving wildfire. This isn’t just a precaution—wildfires have already been reported in parts of Central Texas, and conditions will only get worse if people aren’t careful.
How You Can Stay Safe
- Avoid outdoor burning! That means no campfires, fire pits, or grilling in open areas.
- Be mindful of cigarette disposal. One flicked cigarette can spark a major fire.
- Secure loose outdoor objects. Strong winds can send lightweight debris flying.
- Hydrate, hydrate, hydrate! It may only be March, but these temps feel like peak summer—heat exhaustion is a real risk.
A Special Celestial Treat: Lunar Eclipse Tonight!
Here’s a little bonus: a total lunar eclipse will light up the sky tonight! The eclipse begins at 10:57 PM and reaches peak coverage at 1:26 AM. The only downside? Cloud cover may block the view, so keep your fingers crossed for a clear patch!
Final Thoughts
San Antonio, today is all about fire danger and staying cool in this early blast of summer heat. Keep an eye on local fire warnings, drink plenty of water, and enjoy the lunar eclipse if the skies cooperate! Relief from the heat is coming soon, but for now, stay safe, stay smart, and stay cool!
