Very Low Pollen in Sunnyvale, CA

About pollen in Sunnyvale

Pollen activity in Sunnyvale is quiet today. Grass is the only type registering any presence, and even that is at a very low level, unlikely to cause much trouble for most people. Tree pollen is essentially absent right now, so overall this is an easy day for anyone who typically deals with springtime reactions to trees like plane, pistacia, prunus, celtis, or honeylocust. Looking ahead, conditions should hold steady over the next several days, with grass pollen expected to remain at that same low level and tree pollen staying quiet. This fits the seasonal pattern, since the major tree pollen release in this area typically wraps up earlier in the year, and grass pollen tends to linger at modest levels through the early summer before tapering off. For now, there is little reason to expect any significant shift in symptoms in the near term.
