Pollen in San Mateo, CA

About pollen in San Mateo

Mid-November tends to be a quiet stretch for pollen in San Mateo, and today looks consistent with that pattern. Trees, grasses, and weeds are all largely dormant or winding down at this point in the year, so most people should find the air fairly calm, with little in the way of airborne pollen to cause irritation. Looking ahead, conditions should remain settled through the next few days, as the region sits in the seasonal lull between fall weed pollen fading out and the earliest tree pollen of late winter and spring. When trees do become active again, oak, birch, and alder are typically among the first to release pollen in the Bay Area, with grass pollen following in late spring and ragweed returning toward late summer. For now, there is little seasonal activity to anticipate in the near term.
