Moderate today, mostly weed pollen.
Last updated August 15, 2026
Weed pollen is the main story in Overland Park today, sitting at a moderate level that sensitive individuals will likely notice. Tree pollen, by contrast, is very low and shouldn't cause much trouble. Overall, expect a moderate day, with any discomfort tied mainly to weeds rather than trees. Looking ahead, weed pollen is expected to hold steady over the next several days before ticking up slightly toward the end of the stretch, so those affected should brace for conditions to stay about the same or become a bit more noticeable. Tree pollen will remain very low throughout, with only a slight uptick by the fifth day. This pattern fits the season well: local trees like maple, pine, ash, oak, and pyrus are well past their spring peak and largely dormant now, while late summer is prime time for weeds such as ragweed to become the dominant allergen.
