Very Low Pollen in Pasadena, TX

About pollen in Pasadena

Pollen levels around Pasadena remain quiet today, with grass and weed pollen both at very low levels and tree pollen essentially absent. Most people should notice little to no irritation, though those especially sensitive to grass or weeds may feel a slight effect on days spent outdoors. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass and weed pollen staying in the very low range and tree pollen remaining quiet. This lull fits the season, as trees like oak, elm, and liquidambar have long since finished their spring release, and the more noticeable ragweed and other weed pollens typical of late summer have not yet picked up in earnest. For now, conditions favor easy breathing across the area.
