Pollen in Sunnyvale, CA

About pollen in Sunnyvale

Pollen counts in Sunnyvale are quiet today, with tree pollen sitting at essentially none. This is a welcome stretch for anyone sensitive to airborne allergens, as there is little to nothing circulating that would trigger symptoms right now. Looking ahead, conditions are expected to remain calm over the next few days, with no meaningful tree pollen activity in the forecast. This fits the season well, since local trees such as plane, pistacia, prunus, celtis, and honeylocust typically release their pollen in spring rather than in late autumn. For now, those prone to allergies can expect a restful period before activity picks up again when the weather warms.
