Allergy season is when the pollens reach their peak. This typically occurs, in most regions, during the early spring and fall months. During the spring, the trees and grasses begin to grow. This produces high levels of tree and grass pollens. The summer months have lower levels of tree pollen, but the grass pollens remain at peak levels. Summer also is a peak time for molds, since the heat of the season combined with the moisture produced by summer rain establish the perfect breeding ground for mold growth. Fall marks the peak of ragweed season, as well as, high levels of mold from the leaves that have fallen onto the ground mixing with the fall rains. Winter is the best time for ‘most’ allergy sufferers, since most pollens have declined significantly. Unfortunately, if you suffer from dust or pet allergies, allergy season can be considered all year round.
