Willow oak
Quercus phellos
No notable pollen right now.
Last updated July 28, 2026
Pollen activity in Durham is essentially quiet today. Tree pollen is registering as absent, and there are no other readings of note, so anyone sensitive to airborne allergens should find the air comfortable to be in without much fuss. Looking ahead, this calm stretch is expected to hold, with tree pollen staying flat over the next few days. This tracks with the season, since trees like elm, ginkgo, maple, crape myrtle (Lagerstroemia), and redbud (Cercis) typically release their pollen in late winter and spring, well before midsummer. With that window behind us and grass pollen not showing any activity either, conditions should remain settled for now, ahead of the usual late-summer uptick in ragweed.
