Willow oak
Quercus phellos
Very low today, mostly tree pollen.
Last updated August 15, 2026
Pollen activity around Durham remains quiet today. Both tree and weed pollen are at very low levels, so most people should not notice much in the way of symptoms. Trees such as elm, ginkgo, maple, crape myrtle, and redbud are essentially dormant in terms of pollen release this time of year, and weeds are contributing very little as well. Looking ahead, tree pollen is expected to stay minimal through the next several days, which is typical for mid-August since the main tree pollen season runs in spring. Weed pollen, on the other hand, is likely to inch up slightly toward the end of the forecast period as we move closer to the start of ragweed season, which tends to build through late summer and into fall. Overall, conditions should remain comfortable for now, with only a gradual shift toward more noticeable weed pollen in the coming days.
