If you thought this weekend was going to be calm and sunny, think again. San Antonio is about to experience dangerously strong winds, critically dry conditions, and an increased risk of wildfires. The National Weather Service has issued a Red Flag Warning as gusts up to 45 mph could quickly turn any small spark into a fast-moving wildfire.
With warm temperatures, low humidity, and relentless winds, this weekend’s forecast is a recipe for disaster if precautions aren’t taken. Officials are urging residents to avoid any open flames, secure outdoor objects, and stay prepared for potential power outages or emergency situations. Here’s everything you need to know to stay safe during this high-risk weather event.
Saturday: Strong Winds, High Fire Danger, and Poor Air Quality
Saturday’s weather will be anything but ordinary. While temperatures will be pleasant at 81°F (27°C), the biggest concern is the powerful wind gusts and extremely dry air that will blanket the region.
- High: 81°F (27°C) | Low: 52°F (11°C)
- Wind Gusts: Up to 45 mph, creating dangerous conditions
- Humidity Levels: Critically low, increasing fire risk
- Air Quality: Unhealthy due to blowing dust and debris
What This Means for You:
Wildfires Can Start Instantly – With dry vegetation and high winds, even a small spark can turn into a massive blaze. Avoid outdoor burning, grilling, or using tools that generate sparks.
Wind Could Cause Damage – Strong gusts could knock over trees, power lines, and unsecured outdoor furniture. Bring in loose objects to prevent damage or injury.
Poor Air Quality – Blowing dust and debris will create hazy conditions that can cause breathing problems, especially for those with asthma or respiratory issues.
BOTTOM LINE: Avoid activities that involve fire, limit outdoor exposure to dust, and prepare for strong, gusty winds.
Sunday: Calmer, Warmer, and Safer
After Saturday’s extreme conditions, Sunday will bring relief with calmer winds and beautiful sunshine. The fire danger will drop significantly as wind speeds slow down and humidity slightly increases.
- High: 86°F (30°C) | Low: 48°F (9°C)
- Skies: Mostly sunny, warm, and pleasant
- Winds: Light and manageable compared to Saturday
What This Means for You:
Enjoy the Outdoors Again – With lower wind speeds, parks, hiking trails, and patios will be much more comfortable.
Fire Risk Still Exists, But Less Severe – While Sunday isn’t as extreme as Saturday, it’s still best to be cautious with fire-related activities.
Better Air Quality – With less wind, airborne dust and debris will settle, making it easier to breathe.

How to Stay Safe During This Extreme Weather Event
Avoid Open Flames – No outdoor burning, campfires, or grilling. Even discarded cigarettes can start a blaze.
Secure Outdoor Items – Patio furniture, garbage bins, and decorations should be anchored down to prevent them from blowing away.
Be Prepared for Power Outages – Strong winds could knock down power lines, so charge devices and have flashlights ready.
Stay Indoors If You Have Breathing Issues – Dust and debris in the air can cause breathing problems. If you must go out, wear a mask or limit exposure.
Report Fires Immediately – If you see smoke or flames, don’t wait—call 911 so emergency crews can respond quickly.
Final Thoughts: Stay Vigilant, San Antonio!
This weekend is not your typical sunny and breezy forecast. Saturday’s powerful winds and extreme fire risk could make for a dangerous day if precautions aren’t taken.
If you have outdoor plans, be mindful of wind hazards, avoid fire-related activities, and stay weather-aware. Sunday will bring relief, but staying cautious is key to preventing disasters.
