Trees run from March into May, later near the big lakes. This month sits outside the usual tree pollen window for the Midwest & Great Lakes pattern, so today’s tree pollen reading is the modelled value outranking the calendar — this page reports the modelled reading first. The Wisconsin allergy season guide singles out oak in the south and birch in the north, and a September ragweed peak over the farmland.
