Very low today, mostly weed pollen.
Last updated September 29, 2026
Pollen activity in Milwaukee remains quiet today. Weed pollen is present but only at a very low level, meaning most people should not notice any effect. Tree pollen is absent entirely, so there is little to be concerned about on that front for anyone sensitive to airborne allergens right now. Looking ahead, this pattern is expected to hold steady over the next several days, with weed pollen staying low and tree pollen remaining absent. This lines up with the seasonal calendar: local trees such as maple, pine, honeylocust, linden, and ash release their pollen mainly in spring, so their dormancy this time of year is expected. Weed pollen, including ragweed, is more typical for late summer into fall, but its presence here is minimal, making for an easy stretch for allergy sufferers in the days ahead.
