Willow oak
Quercus phellos
Very low today, mostly tree pollen.
Last updated July 20, 2026
Pollen levels in Durham are quiet today, with both tree and grass pollen registering very low. Most people should move through the day without any irritation, and even those who are usually sensitive to pollen are unlikely to notice much of an effect. Looking ahead, this calm stretch appears set to continue, with grass pollen holding steady at low levels over the next several days. This tracks with the season: the heavier tree pollen from species like oak, maple, birch, and ginkgo typically wraps up well before midsummer, and grass pollen, while still present into early summer, is now easing rather than building. With ragweed season still weeks away, this is a comparatively easy stretch for allergy sufferers in the area.
