About pollen in Vacaville
Pollen activity in Vacaville is quiet as mid-November settles in. Trees, grasses, and weeds are all in their dormant or winding-down phase, so most people should find today comfortable with little to no irritation from airborne pollen. Looking ahead, expect this lull to continue over the next few days, which is typical for this point in the year. Local trees such as oak, ash, and olive won't become active again until spring, grasses stay quiet until late spring or early summer, and any lingering weed pollen from the fall season should continue to fade as cooler, damper weather sets in.
