Extremely hot weather can result in heatstroke, heat exhaustion, heat cramps, sunburn, heat rash, and in some instances death. Please take safety measures to stay safe and lend a helping hand to family, friends and neighbors. If you know of a vulnerable person without air conditioning, such as an elderly or infirm neighbor or someone with a drug or alcohol disorder or severe mental illness, please help them get to an air conditioned space between the hours of 10:00 a.m. and 8:00 p.m. If you see someone on the street who may be having a life-threatening reaction to the heat, please call 911. Thank you for doing your part to keep people safe during a heat crisis.

Hot Weather Safety Information

Keep cool and safe with these hot weather tips from the County of Santa Clara Public Health Department:

Hot Weather Safety Tips

  • Drink plenty of water: Drink water even if you don’t feel thirsty. Avoid alcohol, caffeine or lots of sugar because they will speed up fluid loss.
  • Limit physical activity: Avoid physical activity during the hottest time of the day—10 a.m.-3 p.m.
  • Never leave people or pets in a closed, parked car.
  • Stay in air-conditioned areas, whenever possible.
  • Cool off by taking a bath or shower: Cool, plain water baths or moist towels work best. Do not cool children in alcohol baths.
  • Wear cool clothing: Lightweight, light-colored and loose-fitting clothing can help you keep cool. Cotton clothes are good because they let sweat evaporate.
  • Do not bundle babies: Babies do not handle heat well because their sweat glands are not fully developed. Do not put them in blankets or heavy clothing.
  • Cover your head: Wear a wide-brimmed, vented hat or use an umbrella when outdoors because your head absorbs heat easily.
  • Wear sunglasses and sunscreen: Use sunscreen with SPF 15 or higher when outdoors.
  • Rest often in shady areas: Find shady places to cool down when outdoors.
  • Check on frail or elderly family, friends, or neighbors often.

Older adults and individuals with chronic medical conditions:

  • During peak heat hours stay in an air-conditioned area, whenever possible.
  • Older adults and those on certain medications may not exhibit signs of dehydration until several hours after dehydration sets in. Stay hydrated by frequently drinking cool water. If you’re on a special diet that limits liquids, check with your doctor for information on the amount of water to consume.
  • Stay out of the sun if you do not need to be in it. When in the sun, wear a hat, preferably with a wide brim, and loose-fitting, light-colored clothing with long sleeves and pants to protect against sun damage. And remember to use sun screen and to wear sunglasses.

Infants and Children:

  • It is illegal to leave an infant or child unattended in a vehicle (California Vehicle Code Section 15620).
  • Infants and young children can get dehydrated very quickly. Make sure they are given plenty of cool water to drink.
  • Keep children indoors or shaded as much as possible.
  • Dress children in loose, lightweight, and light-colored clothing.
