Seattle residents woke up this week to AQI readings above 150—unhealthy territory. Health officials quickly issued an air quality advisory for the greater Puget Sound region.
The spike comes from industrial emissions combining with weather patterns that trap pollutants close to ground level. When high pressure settles over the area, pollution has nowhere to go. Officials are recommending limited outdoor activity, especially for people with respiratory conditions, older adults, and children.
What to Do Right Now
Keep windows closed during peak pollution hours—typically 6-10 AM and 4-8 PM when traffic compounds the problem. Run HEPA air purifiers if you have them. Before heading out for a run or bike ride, check AirNow.gov for current readings at your location.
A cold front is expected Thursday, which should push the stagnant air out and bring relief. Until then, take the precautions seriously—your lungs will thank you.
