Late spring and early summer bring more pollen in May and June. Grasses are very active then. Meadow grasses, ryegrass, and other wild grasses spread pollen across fields and roadsides. Many plants in gardens also bloom during this time.

Mid to late summer lasts from July into August. Weed pollen becomes more common. Ragweed can appear in some places, along with mugwort and plantain. Dry weather helps their pollen travel farther, especially in open areas and near roads.

Early autumn can still have pollen in September and sometimes October. Weeds may keep releasing pollen for a while. As nights get cooler, pollen levels slowly drop. By late autumn, most trees, grasses, and weeds have finished blooming.
