Extreme Heat!

By Aaron Vazquez and Audrey Santora

How do heat waves happen?

A heat wave is an extended period of extreme heat, and there is often high humidity. There is usually little to no precipitation during a heat wave, making the climate very dry. These conditions can be dangerous to people who don't take care of themselves properly.

What should someone do before and during a heat wave?

  • Build an emergency kit.
  • Make a family communication plan.
  • Keep shades closed on windows that get morning or afternoon sun.


  • Never sit in a parked car.
  • Stay inside as much as possible.
  • Play indoor games and sports.
  • Drink lots of water.
  • Wear loose-fitting and light colored clothes.
  • Wear a hat with a wide brim.
  • Spend time in places with air conditioning.
