Pollen and Hay Fever in Meridian, ID
In Meridian, Idaho, pollen allergies, often referred to as hay fever, are a common issue that many residents face. Pollen, the primary cause of these seasonal allergies, is released by plants during specific times of the year, not throughout all seasons. The primary producers of pollen in Idaho are grasses, trees, and weeds.
In the spring, tree pollen is the main culprit. Levels can be very high, especially for certain types of trees that are common in the area, such as juniper, cottonwood, maple, walnut, and willow trees. Pollen allergies typically start flaring up in late February or early March, following the mild and wet winters of Idaho. April is a month to be particularly cautious as pollen counts can peak during this time.
As we move into the summer months, grass pollen takes center stage. Grasses such as ryegrass, Bermuda grass, orchard grass, and bluegrass are common in Idaho and can contribute to high pollen counts during this season. June is another month when the pollen count can be particularly high.
In the fall, weeds like sagebrush, pigweed, and tumbleweed produce pollen, leading to a spike in allergy symptoms. This phase of pollen allergies can persist until late summer and up until the end of the allergy season, which is typically around late October when the first frost occurs.
Remember, the overall allergy risk could still be high even when the overall pollen count is low because a specific type of pollen could be prevalent in the environment. Therefore, understanding the different types of pollen and the seasons when they are most prevalent can help you anticipate and manage pollen allergies more effectively.
