About pollen in Hayward
Grass pollen is the main story in Hayward today, and it's sitting at a low level overall. Most people should be able to go about their outdoor plans without much irritation, though those who are especially sensitive to grass pollen may notice mild symptoms during peak afternoon hours. Looking ahead, grass pollen is expected to ease slightly over the next several days, settling into an even quieter pattern through the workweek. This lines up with the seasonal shift in the Bay Area, as the region moves past the peak grass season that typically runs through late spring and early summer. Tree pollen from local species like oak and olive has largely wound down by this point in the year, so grass remains the primary factor to keep in mind for anyone who tends to react to outdoor pollen this time of season.
