Spring brings many more pollen sources. Birch is common in April and May. Oak, poplar, and pine may also release pollen then. Grass pollen starts to rise in late spring. Fields, lawns, and roadsides can all add more pollen to the air.

Summer is the main grass pollen season. June and July often have the most grass pollen. Meadow grasses, ryegrass, and other wild grasses are active. In warm, dry weather, pollen can travel farther and stay in the air longer.

Late summer and early autumn bring weed pollen. Mugwort is a main plant in August and September. Plantain and nettle can also release pollen. By October, cooler days usually slow pollen release, and the season starts to fade.
