Red maple
Acer rubrum
Very high today, mostly weed pollen.
Last updated September 29, 2026
Weed pollen is dominating the air in Overland Park today, reaching levels that are likely to cause significant discomfort for anyone with sensitivities. This is the main driver of overall pollen activity right now, while grass remains low and trees are quiet for the season. Expect weed pollen to stay very high for another day before easing considerably, then climbing back into the moderate range as the week progresses. This pattern is typical for early fall, when ragweed and related weeds are at their most active. Grass pollen should continue to fade into the background over the coming days, and with trees like maple, pine, ash, oak, and pyrus well past their spring release, tree pollen is not a concern at this time of year.
