In spring, more trees and plants bloom. Oak and pine can add pollen too. Grasses begin later in the season. Their pollen often becomes stronger from late April into June. This is one of the busiest pollen times of the year.

In summer, grass pollen stays important. Meadow grasses, ryegrass, and other common grasses send out pollen through June and July. Warm, dry weather can make it spread farther. On some days, weeds also start to bloom and add more pollen.

In late summer and early fall, weed pollen becomes more common. Mugwort is a main example in this region. It usually peaks from August to September. By October, pollen levels often drop as the weather turns cooler and many plants finish flowering.
