According to Dr. Manan Shah of Wyndly, Pennsylvania has one of the highest concentrations of pollen in the country. Pennsylvania’s allergy season, according to Wyndly, can start as early as February and usually lasts until the first hard freeze of winter.
In spring, tree allergy season takes over, which can last from the late winter months and run all the way into late May. Common tree allergies for Pennsylvania include hickory, ash, maple, walnut, oak, willow, and mulberry.
Summer is when tree pollen dies down, but grass pollen becomes an issue. This season starts in mid-May and tapers off around mid-August. Common grass allergens include bent, fescue, orchard, brome, sweet vernal, and timothy grass.
Fall is prime time for weed allergy season, which lasts from mid-August until the first hard freeze of the winter. This can include allergens such as ragweed, wormwood, araanth, orache and sagebrush.
Winter marks the end of pollen allergy season. But, depending on your specific set of allergies, indoor allergies such as mold, dander, and dust can cause you to feel sneezy.
