Willow oak
Quercus phellos
Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main driver in Durham today, sitting at a Low level (2) and accounting for the overall Low reading. Tree pollen has dropped to None, which is typical now that the spring contributions from local species like Elm, Maple, Ginkgo, Lagerstroemia, and Cercis have wound down. The five-day outlook holds grass steady at Low across the board, so expect little change in the days ahead. This pattern fits the early-summer window, when grass tends to dominate after the spring tree season fades. Weed pollen data isn't available right now, though ragweed generally won't become a factor until later in the summer and fall.
