About pollen in Berkeley

Pollen levels around Berkeley are quiet today, with both tree and grass pollen sitting at very low levels. Most people should be able to go about their day without much irritation, even those who are typically sensitive to seasonal allergens. Overall, it is a mild day for anyone who watches pollen counts closely. Looking ahead, conditions are expected to hold steady over the next couple of days, with tree and grass pollen staying in the low range. This lull fits the season well: the heavier tree pollen from species like oak, ash, and plane trees typically peaks earlier in spring, and grass pollen usually tapers off as summer settles in. With ragweed season still weeks away, this is generally a calmer stretch for allergy sufferers in the area.
