March is a month known for its unpredictability, from the weather to your odds of filling out a perfect March Madness bracket.

The Final Four has taken over San Antonio with plenty of activities to enjoy. You’ll want to be aware of the weather because a cool front dribbled in early Saturday, bringing a game-changing change in temperatures for South Texas. Here’s what you need to know:

FAN FEST

Of course, the games and Fan Fest are held indoors, where temperatures and wind are not a factor. However, the walk from the parking lot to the Alamodome or the Henry B. González Convention Center may be most inconvenient.

MARCH MADNESS MUSIC FESTIVAL

If you’re planning on attending the free March Madness Music Festival at Hemisfair, bring a jacket! Temperatures are only going to get into the 60s. With a slight wind, temperatures can even feel slightly cooler. Other than breezy winds, there shouldn’t be any weather issues for tonight’s concerts.
