Very Low Pollen in Sunnyvale, CA

About pollen in Sunnyvale

Pollen activity in Sunnyvale is quiet today. Tree pollen is absent altogether, while grass and weed pollen are both present only at very low levels. Most people should notice little to nothing in the way of symptoms, though those who are especially sensitive might catch a faint trace of grass or weed pollen in the air. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass and weed pollen staying low and tree pollen remaining absent. This lull fits the season: local trees such as Plane, Pistacia, Prunus, Celtis, and Honeylocust are well past their spring release and are dormant now, and while late-summer weeds like ragweed can occasionally linger into fall, current levels suggest no notable uptick is on the horizon.
