Last updated July 28, 2026
Pollen levels in Knoxville are quiet today, with tree pollen sitting at essentially none. Anyone who deals with seasonal allergies should get a bit of a break, as there is little in the air right now to cause irritation. Looking ahead, tree pollen is expected to stay low over the next stretch, which lines up with the time of year. The spring push from trees like elm, oak, maple, zelkova, and carpinus wrapped up months ago, and midsummer tends to bring a natural lull before ragweed and other late-season plants become more of a factor as fall approaches.
