Bay Area folks, it’s going to be hot this week.

The National Weather Service has issued an Excessive Heat Warning for the Bay Area that started Monday. In response, the Santa Clara County Office of Emergency Management is calling on residents to take critical precautions as the region braces for an intense heat wave.

The anticipated extreme heat significantly raises the likelihood of heat-related illnesses, including heat exhaustion and heat stroke. Children, older adults and people with underlying health conditions are at a greater risk.

“It’s essential for everyone to stay aware and take action to protect their own health and the well-being of their families,” said Dana Reed, Director of Emergency Management for Santa Clara County. “Simple steps like staying hydrated, avoiding outdoor activities during peak heat, and checking in on others can prevent heat-related illnesses and death.”

It is important that you are vigilant and take proactive measures to protect your and your family’s health.

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.
  • Check on frail or elderly family, friends, or neighbors often.
  • 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 shaded areas: Find shady places to cool down when outdoors.

County libraries are operating as Cooling Centers to provide a safe, air-conditioned space for community members seeking relief from the heat.
