Beat the Extreme Heat

Stay Cool and Beat the Heat

Extreme heat is a period of high heat and humidity with temperatures above 90° F (32° C) for at least two to three days. In extreme heat your body works extra hard to maintain a normal temperature. Extreme heat is responsible for the highest number of annual deaths among all weather-related hazards. It’s important to know the signs of heat illness and make sure you’re prepared for the next heat wave.

STAY COOL

Stay hydrated: Drink a lot of water, more than you normally would. Don’t wait until you are thirsty to drink water.

Plan cool activities: See a movie, visit a public library, take a cold shower…all of these activities are encouraged by local authorities during extreme heat.

Plan outdoor time carefully: Limit outdoor activity and exercise if possible to keep cool. If you must go outside, avoid going out in midday when the sun is hottest. Wear lightweight, loose-fitting clothing, plus a hat and sunscreen, and rest often in shady areas.

Visit a cooling center: If your home is too warm, move to a cooling center near you. A listing of cooling centers throughout California can be found here.

STAY AWARE

Watch for signs of heat illness, such as heat exhaustion or heat stroke. The National Weather Service offers this quick reference guide to help you understand the symptoms and act fast.

DO YOUR PART

Extreme heat puts the vulnerable at increased risk and strains critical infrastructure like electrical grids. Please consider taking these steps to help your local community.

Conserve energy: Check your ‘stat and your consumption during a heat wave:

  • Thermostats should be set to 78° (25° C) or higher, if health permits
  • Don’t run large appliances during peak energy use time (approx. 3-9 p.m.) – the laundry and dishwasher can wait
  • Turn off unnecessary lights
  • Unplug or turn off electrical devices that are not in use
  • Hold off on charging your electric vehicle until an off-peak hour

Check in on others: Check in on your neighbors. Extreme heat can be especially dangerous to the elderly, kids, and pets. Offer water and information on cooling centers if needed. Never, ever leave children or pets in cars. Always keep pet water bowls filled, and out of direct sunlight.
