San Antonio will trade rain for heat this week

Soaked soils will keep humidity, heat index high

Even though high temperatures will be in the low to mid-90s, high humidity will put the heat index near 100° each afternoon (Copyright 2021 by KSAT - All rights reserved.)

SAN ANTONIO – Since the end of April, the weather has been pretty active with showers and storms every week. This has been great for the Alamo City, as drought has been eliminated and the Edwards Aquifer continues to rise.

However, as we have settled into a quiet weather pattern this week, soaked soils have increased the humidity. This means that the heat index values have been high in the afternoons, and it will feel hotter than 100 degrees just about every day.

Stay Cool, Y’all

Even though we’re Texans and are used to the heat, it’s important to remember these safety tips to avoid heat-related illnesses:

  • Drink plenty of water and stay hydrated
  • Reduce strenuous outdoor activities
  • Find shade or air-conditioned places
  • Wear lightweight, light-colored clothing
  • Check on the elderly, who are more susceptible to heat-related illness
  • Walk your dogs in the morning or in the evening to avoid injuring their paws. If you have to take your puppers for a walk in the afternoon, keep on the grass or use heat-safe walking shoes

Never Leave Children In A Parked Vehicle

According to Kids and Cars, 53 children became victims of hot car deaths in 2019. 25 children died in hot-car related deaths in 2020. Officials are reminding people to never leave children or pets in vehicles.

In the summer, our cars can act like ovens. This can be very dangerous if children or pets are left unattended in a vehicle. KSAT Meteorologist Sarah Spivey explains just how toasty it can get in a car in a matter of minutes.

Heat Index 101

Why does humidity make it feel hotter than it actually is outside? Meteorologist Kaiti Blake explains in the video below, and even shows how you can calculate the heat index at home.

Meteorologist Kaiti Blake takes some time to discuss the science behind the heat index and how high humidity can make a hot day dangerous.
