Air quality expected to stay unhealthy through the week

Smoke from wildfires will continue to plague King County with unhealthy air quality. While the forecast has smoke staying through the week, air quality may change frequently throughout the day, and may be different from location to location. Check for updates. Residents are encouraged to take precautions as levels will stay around “unhealthy for sensitive groups” to “unhealthy” for everyone. Please check back for more updates.

Protect your health when air is smoky

Check the air quality forecast. Air quality conditions may change quickly. Go to Puget Sound Clean Air Agency’s website at or follow them on Twitter (@pscleanair) for the current smoke level report for King County. Stay indoors when possible. Limit your physical activity outdoors (including running, biking, physical labor, and sports) when:

  • the smoke level is “moderate” or worse if you have a health condition (like asthma, heart disease, diabetes, or a cold)
  • the smoke level is “unhealthy for sensitive groups” or worse if you are pregnant, over age 65, a child or an infant
  • the smoke level is “unhealthy for everyone.”

Keep indoor air clean. Close windows and doors. Don’t smoke, use candles, or vacuum. Use an air cleaner with a HEPA filter if possible. Use fans or an air conditioner (AC) when it’s hot, if possible. Set your AC to recirculate, rather than bringing in fresh air. If you aren’t able to leave and it’s too hot, it’s better to open the windows for a short time to cool the indoor space than to overheat. If you do use AC, be sure to check and clean or change the filter regularly. If your health conditions get worse around smoke, contact your health care provider. Call 9-1-1 if you or someone else has serious symptoms, like trouble breathing.

Check on others. Check on elderly or at-risk neighbors. Make sure they have what they need. Offer them a place with cleaner indoor air if available. Public Health – Seattle & King County has additional information and tips about dealing with wildfire smoke.

Tips for pets

Animals also face challenges during the wildfire smoke season. Regional Animal Services of King County (RASKC) provides information for people to help their pets in emergencies, including summer heat and wildfires. As with humans, try to limit your pet’s outdoor activity when weather conditions are at their worst. Always make sure pets have plenty of cool water and shade available, and never leave a pet in a hot car. Check heat safety tips for pets for information. If you need to evacuate due to smoke or wildfire, have a plan to take your pet with you.

Keep your cool this summer

Summer is here! Forecasts call for a gradual warming, with temperatures on Sunday, Aug. 16 reaching 90 in the Seattle area and even the mid- to upper 90s inland. This is likely to bring high risk for much of the population, especially those who are heat sensitive and those without effective cooling and/or adequate hydration.

Things are different this year with COVID-19. Going to a movie theater, a mall, or the library to cool off after work isn’t possible for most of us in King County in this phase of the state’s Safe Start reopening plan. Remember to let safety be your guide. Due to the extremely dry conditions, King County Fire Marshal has issued a burn ban for unincorporated areas in King County.

Tips from Public Health – Seattle & King County specific to COVID and heat:

  • COVID risk adds an additional concern during hot weather. Unlike the flu, hot weather does not decrease the transmission of COVID-19.
  • Cities will not be able to set up cooling centers this summer with the increase in COVID-19 spread.
  • Many swimming beaches may be closed or lifeguards may not be present. Never swim alone, use lifejackets in or near rivers and lakes, and heed Public Health warnings about crowded parks. Get more information about safe swimming in COVID times.
  • Wearing a mask is a key measure to prevent the spread of COVID; in hot weather, wearing a mask can also contribute to overheating. Avoid spending time in hot indoor and outdoor locations where you would have to wear a mask. Take a safely distanced “mask break” if you are getting too hot and uncomfortable:
    • Go outside and make sure you are distanced from others by at least six feet.
    • Remove your mask to breathe and cool down.
    • Put the mask back on before returning to the venue or activity where the mask is required.

For everyone when days are hot:

  • Keep window blinds or curtains closed when outdoor temperatures skyrocket. This reduces indoor temps and reduces the strain on cooling equipment, if in use.
  • Keep windows and doors closed in locations with air conditioning.
  • Drink plenty of fluids (but avoid alcohol, caffeine, or lots of sugar that can make you lose body fluid).
  • Dress in layers to manage varying temperatures.
  • Minimize extended time outside.
  • Turn off unnecessary lights and unplug unused electrical equipment.
  • Take a tepid shower or bath to cool down.
  • Avoid hot and heavy meals that can raise your body temperature.
  • Check on vulnerable family or neighbors by phone or text to make sure they are safe and cool.
  • NEVER leave pets or children in a hot car. Call 9-1-1 if you see a child or pet in a hot car.
  • Learn the warning signs of heat illness that happens when the body can’t cool down. If someone has heat stroke, they need to call 9-1-1 or go to the emergency room immediately.

If you must be outside:

  • The most important thing to do is to drink lots of water. When it’s really hot, drink up to a quart of water every hour with moderate to heavy physical activity.
  • Carry a water bottle.
  • Consider sports drinks for electrolyte replacement when sweating a lot.
  • Wear loose, light clothing with materials designed to wick sweat.
  • Wear a hat with a brim.
  • Check with your supervisor about adjusting your work hours to start earlier, when it’s cooler.
  • Stop all activity if you become lightheaded, confused, weak, faint or have a pounding heart or trouble breathing.
  • Hot, sunny weather invariably brings more people to King County’s parks and trails, which are open consistent with the state’s Phase Two guidelines. More information about what is open can be found on Parks’ COVID-19 response page.
  • Park and trail visitors can report crowding, areas that need attention, or other issues using Parks’ reporting tool, SeeClickFix.
