Extreme Heat

Extreme heat is the deadliest weather related hazard. In the United States, extreme heat is defined as a long period (2 or more days) of high heat and humidity with temperatures above 90 degrees. In extreme heat, evaporation slows and our bodies have to work harder to maintain normal temperatures, which can lead to illness or even death from overworking the body.

Extreme heat can impact anyone, but older adults, young children, and people who are sick are more at risk.

See current Kirkland weather conditions.

​Before Extreme Heat

  • Keep buildings cool by covering windows with drapes or shade, using air conditioning, and weather stripping windows and doors.
  • Identify places in the community to cool down. Shopping centers, movie theaters, libraries, and community centers are good places to go.
  • Kirkland has lots of aquatic options to beat the heat, but be sure to enjoy them safely. Wear personal flotation devices and swim at locations with life guards.
  • Know the signs of heat related illness and how to treat them. 

During Extreme Heat

  • Find areas with air conditioning.
  • Avoid strenuous activities.
  • Wear light clothing. Wear a wide-brimmed hat if you must be outside. Wear sunscreen on any exposed skin.
  • Check for signs of heat related illness. Seek medical care if symptoms include nausea or throwing up, dizziness or confusion, of if they last for longer than 1 hour.
  • Check on neighbors, especially those that may be more susceptible to heat-related illness.
  • Drink lots of water.
  • Never leave people or pets in a car, even with the windows open.
  • Know that fans do not reduce body temperature. Fans create airflow and a false sense of comfort, but they do not help prevent heat-related illness.

Heat-Related Illness

Heat-related illnesses are preventable and occur when the body can't cool itself down fast enough.
