Seattle’s air quality index hit “Good” for 15 straight days this month—the longest clean air streak since regional monitoring began. Residents have been enjoying weather perfect for outdoor activities without the usual pollution concerns.
Why the Air’s Been So Clean
Meteorologists credit favorable wind patterns pushing clean coastal air inland, combined with lower traffic during the holiday season. The Puget Sound Clean Air Agency confirmed that industrial emissions also dropped 12% compared to the same period last year.
Making the Most of It
Wildfire season is still months away, but indoor air quality experts recommend using this clean air period for maintenance. Service your HVAC system now while technicians aren’t overwhelmed. Stock up on replacement filters before demand spikes. A little preparation goes a long way when smoke season eventually arrives.
And even during these good outdoor days, running air purifiers inside helps maintain consistent home air quality—no reason to stop just because the numbers look good outside.
