Low Pollen in El Cajon, CA

About pollen in El Cajon

Weed pollen is the only real presence in El Cajon today, and it's holding at a low level. Tree and grass pollen are both quiet, so most people should find the air fairly easy to breathe, with only those especially sensitive to weeds likely to notice any effect. Looking ahead, weed pollen is expected to remain steady at this low level through the next several days, without any sharp rises or drops. This fits the seasonal pattern for late September, as tree pollen from species like Ash, Liquidambar, Pine, Washingtonia, and Yucca stays dormant until spring, and grasses remain inactive until closer to early summer. Weeds, on the other hand, are typically the main source of pollen this time of year, so their presence—even at a low level—is consistent with what's expected locally in early fall.
