Pollen in Pittsburgh, PA

About pollen in Pittsburgh

Pollen levels across Pittsburgh are quiet today, with tree pollen sitting at essentially none. Anyone who typically reacts to airborne pollen should find little to contend with outdoors right now. Looking ahead, that calm is expected to hold over the next several days, with tree pollen staying flat and inactive. This lines up with the season: by mid-November, trees like honeylocust, elm, pyrus, maple, and zelkova have long since finished releasing pollen for the year, and the next uptick for these species won't arrive until growth resumes in spring.

What to do today

• Pollen is minimal today, so it's a great time to be outside.
