Low today, mostly grass pollen.
Last updated July 1, 2026
Grass pollen is the main player in Knoxville today, sitting at a Low level (index 2) and driving the overall reading, which also lands at Low. Tree pollen is registering none right now, which fits the late-June calendar: the spring surge from local species like Oak, Maple, Zelkova, Elm, and Carpinus has wound down, leaving grasses as the dominant source typical of early summer. The forecast keeps grass steady at Low for the next couple of days before easing slightly toward the end of the period. No weed pollen data is available at the moment, though that category tends to climb later in the season with ragweed. Overall, expect generally manageable conditions through the coming days.
