With dry winds and the occasional blistering day, Wyoming has plenty of potential allergies in the summertime, more specifically during the months of June through August. This is also the most common time of year for tourists to flock to Yellowstone National Park, so don’t forget your antihistamines! Grass allergies are incredibly common in Wyoming. Some grasses that cause allergies include prairie, Bermuda, bent, rye, and bluegrass.

Fall

Beginning in late August and likely lasting until the end of October, weeds cause the most sneezes in Wyoming. Some grass allergies may also still persist, depending on weather conditions. However, one weed in particular causes some of the worst allergy symptoms in the US: ragweed. It grows in Wyoming too, alongside other weeds such as amaranth, sagebrush, mugwort, and smotherweed.

Winter

Thankfully, winter weather conditions typically bring the Wyoming allergy season to a screeching halt. This mountainous region gets plenty of snow, but the valleys in between all of these mountains make for some dry and windy winters. Many Wyoming residents may struggle with dry and itchy skin in the wintertime. Plus, dust and dander are often a problem during the months of November through February, as more people spend time indoors.
