San Antonio, March 11, 2025 — Spring break may be in full swing, but San Antonio’s weather is taking an early summer turn. This week, residents can expect soaring temperatures, dry conditions, and an elevated wildfire threat, making it crucial to stay informed and prepared. While many will welcome the sunshine, these extreme conditions can be dangerous if precautions aren’t taken. Here’s what you need to know.
Unseasonable Heatwave: Breaking Records?
San Antonio is no stranger to warm weather, but this week’s forecast is setting the stage for some near-record-breaking highs. A strong high-pressure system is locking in heat, driving temperatures well above the historical March averages. Here’s what to expect:
- Tuesday, March 11: A warm and partly sunny day, with highs reaching 84°F (29°C) and a comfortable overnight low of 56°F (14°C).
- Wednesday, March 12: Sunny and even warmer, with highs near 88°F (31°C). A breezy afternoon could make it feel even hotter.
- Thursday, March 13: The hottest day of the week, with temperatures spiking to 92°F (33°C), approaching record highs.
- Friday, March 14: Another scorcher, reaching 93°F (34°C). Winds will increase in the afternoon, potentially worsening fire conditions.
- Saturday, March 15: A slight cooldown, but still hot, with highs near 85°F (30°C).
- Sunday, March 16: More sunshine, with highs hitting 89°F (32°C).
- Monday, March 17: Warm and partly cloudy, with highs around 87°F (31°C).
This level of heat in early March is unusual—San Antonio’s average high this time of year is mid-70s°F (around 24°C). With no significant rain in the forecast, the dry conditions will only worsen.
Fire Danger on the Rise
One of the biggest concerns this week is the increased wildfire risk. With strong winds, dry air, and rising temperatures, conditions are ripe for fast-spreading fires. Authorities have issued a wildfire alert for parts of South and Central Texas, including Bexar County, the Hill Country, and the Rio Grande Plains.
Key fire risks include:
- Low humidity and gusty winds that can spread flames rapidly.
- Dry vegetation that can ignite easily.
- Outdoor activities like grilling or using machinery that produces sparks.
Safety Tips to Beat the Heat and Stay Fire-Safe
- Hydrate, Hydrate, Hydrate – With high temperatures, dehydration can happen quickly. Drink plenty of water throughout the day.
- Avoid Peak Heat Hours – Try to limit strenuous outdoor activities between 12 p.m. and 5 p.m. when the sun is strongest.
- Fire Prevention – Avoid burning debris, use caution with grills, and dispose of cigarettes properly.
- Check on Vulnerable Individuals – The elderly, young children, and pets are especially at risk during extreme heat.
Looking Ahead
A Pacific cold front is expected to arrive late Friday, offering some relief with temperatures dropping by about 10 degrees into the weekend. However, the fire risk will remain high, so continued caution is necessary.
San Antonio, stay cool, stay safe, and be mindful of fire dangers this week!
