About pollen in Mountain View

Weed pollen is the only type registering in Mountain View today, and it remains at a low level. Most people should get through the day without much irritation, though those with a strong sensitivity to weed pollen may notice mild effects, particularly during outdoor activity in the afternoon. Looking ahead, weed pollen is expected to hold steady at this same low level through the next several days, with no significant swings in either direction. This is consistent with mid-August, when tree pollen from species like oak and birch has long since wound down and grass season has passed its peak, leaving weeds such as ragweed as the primary source of pollen as late summer moves toward fall. For now, conditions remain manageable across the region.
