Pollen in Louisville, KY

About pollen in Louisville

Pollen counts across Louisville are quiet today, with tree pollen registering essentially absent. Anyone who struggles with seasonal allergies should get a welcome break, as there is little in the air right now to trigger symptoms. Looking ahead, tree pollen is expected to stay low over the next several days, which lines up with the time of year — trees such as elm, dogwood, fringetree, and smoketree typically release their pollen in spring, not midsummer, so their contribution is naturally minimal now. Grass pollen can still be a factor into early summer for sensitive individuals, and ragweed season remains a couple of months off, so this looks to be a comparatively calm stretch overall.

What to do today

• Pollen is minimal today, so it's a great time to be outside.
• No special pollen precautions are needed right now.
