Understanding Tree Pollen: A Comprehensive Guide for Allergy Sufferers in the United States

Tree pollen is a significant allergen affecting millions across the United States, especially during the spring and early summer months. Understanding its patterns and managing exposure is crucial for those sensitive to these allergens.

What Is Tree Pollen?

Tree pollen consists of microscopic grains released by trees during their reproductive cycle. These grains are carried by the wind, leading to widespread distribution. Common trees that produce allergenic pollen include oak, birch, cedar, alder, and maple. In the U.S., tree pollen season typically spans from February to May, with peak levels in March and April.

How Does Tree Pollen Affect Allergies?

Exposure to tree pollen can trigger allergic reactions such as sneezing, runny nose, itchy eyes, and sinus congestion. For individuals with asthma, tree pollen can exacerbate symptoms, leading to increased wheezing and difficulty breathing. The severity of these reactions varies based on individual sensitivity and pollen concentration.

Current Tree Pollen Levels Across the U.S.

As of June 18, 2026, tree pollen levels have generally decreased across most regions, transitioning into the grass pollen season. However, localized variations may still occur. For instance, in Danbury, Connecticut, the pollen level is currently moderate, with grasses being the primary allergen. (allergyava.com)
