About pollen in Oakland

Pollen levels around Oakland are quiet today. Tree pollen is absent entirely, while grass and weed pollen are both present only in trace amounts. Most people, even those with sensitivities, should find little to notice outdoors right now. Looking ahead, this calm pattern is expected to hold steady over the next several days, with grass and weed pollen staying at low, barely noticeable levels. Tree pollen should remain a non-issue as well, which fits the season—local trees such as plane, ash, and prunus typically release their pollen in spring rather than fall. Weed pollen often lingers longer into autumn, but current readings suggest nothing significant is building for now.
