Pollen in Pasadena, TX

About pollen in Pasadena

Pasadena's air is clear of pollen today, with tree sources such as oak, elm, liquidambar, celtis, and salix all quiet. Anyone who deals with seasonal allergies should get a break, as there is little in the way of airborne irritants to contend with right now. Looking ahead, tree pollen is expected to stay low through the next several days, which lines up with the season, since these trees typically release their pollen in spring rather than in the heat of midsummer. As late July continues, grass and weed pollen tend to be the more likely sources of irritation for sensitive individuals, so it is worth keeping an eye on those categories even as tree pollen remains a non-issue for now.
