About pollen in Hayward
Pollen levels in Hayward are quite low today, with weeds accounting for the only measurable activity in the air. Even so, the presence is minimal enough that most people, including those with sensitivities, should notice little to no effect. It is a calm day overall for allergy sufferers in the area. Looking ahead, weed pollen is expected to stay low through the next few days, with a slight uptick possible toward the end of the five-day stretch. This gradual rise fits the seasonal pattern, as late summer typically brings increasing weed pollen, including ragweed, as it moves toward its more active fall stretch. Tree pollen, which peaked back in spring for local varieties like oak and birch, remains a non-factor this time of year, and grass pollen has also largely wound down after its late spring push.
