Willow oak
Quercus phellos
Moderate today, mostly weed pollen.
Last updated October 14, 2026
Weed pollen is the main source of irritation in Durham today, sitting at a moderate level that could be noticeable for those who are sensitive. Tree pollen is quiet, with no activity to speak of, so any symptoms this week are likely coming from weeds rather than trees. Looking ahead, weed pollen is expected to remain a steady presence over the next several days, dipping slightly tomorrow before settling back into the moderate range through the rest of the week. This fits the seasonal pattern for mid-October, when ragweed and other late-season weeds tend to linger even as tree pollen stays dormant. Local trees like elm, maple, and cercis won't become a factor again until closer to spring, so for now weeds remain the one to watch.
