Low Pollen in Louisville, KY

About pollen in Louisville

Grass pollen is the main driver in Louisville today, sitting at a Low level on the index while overall pollen also registers Low. Tree pollen has dropped to Very Low, which is expected now that the spring peak for oak, maple, honeylocust, Cladrastis, and Picea has passed. The grass forecast holds steady in the Low range over the next five days, easing slightly midweek before edging back up. This fits the season, as grass typically leads pollen activity through late spring and early summer. Ragweed and other weed pollen are not yet reported and generally become a factor later in the summer and into fall.
