About pollen in Santa Clara

Pollen activity in Santa Clara is quiet today, with tree pollen sitting at essentially none. There is little reason to expect any outdoor discomfort from airborne pollen at this point, making it a comfortable day for those who are usually sensitive to tree allergens like pistacia, liquidambar, ginkgo, syagrus, or maple. Looking ahead, conditions are expected to remain calm over the next few days, with tree pollen staying low. This fits the season well, since early October falls outside the typical spring window when local trees release their heaviest pollen loads. With grass season behind us and ragweed not a major factor in this area, allergy sufferers should find this a relatively easy stretch for breathing easy outdoors.
