Low today, mostly grass pollen.
Last updated July 1, 2026
Pollen levels across Seattle sit in the Low range today, with both tree and grass each registering a 2 on the Universal Pollen Index. Grass is the more persistent factor right now, holding steady at 2 throughout the five-day forecast, while tree pollen is on the way down and starts the window at just 1. The local tree species that drive allergenic counts here — Oak, Maple, Liquidambar, Ash, and Plane — are well past their springtime peak, which fits the easing tree trend. Grass pollen, typical of late spring and early summer, is the type to watch as it lingers at a steady low level. No weed data is available at this time.
