Understanding the 2026 Pollen Season: A Step-by-Step Outlook

The 2026 pollen season is expected to be notably intense and prolonged across the United States. Climate change has led to longer growing seasons, resulting in earlier and more intense pollen releases. Between 1970 and 2024, nearly 90% of 198 U.S. cities experienced longer growing seasons, with an average extension of 21 days. (climatecentral.org)

Step 1: Early Tree Pollen Release

In early spring, tree pollen levels begin to rise, particularly in southern regions. Species such as birch, cedar, and oak are primary contributors. Warmer temperatures and extended freeze-free periods have led to earlier pollen releases. (neefusa.org)

Step 2: Grass Pollen Surge

As spring progresses into late spring and early summer, grass pollen levels increase. This surge is influenced by factors like temperature, rainfall, and wind patterns. Warmer temperatures and early spring conditions have driven the early start of grass pollen season. (patch.com)

Step 3: Weed Pollen Peak

In late summer and fall, weed pollen, especially ragweed, becomes prevalent. Climate change has contributed to longer and more intense allergy seasons, with ragweed pollen seasons starting earlier and lasting longer in many regions. (weence.com)

Factors Influencing Pollen Intensity

• Climate Change: Warmer temperatures and increased CO₂ levels have led to longer and more intense pollen seasons. (climatecentral.org)

• Weather Patterns: Temperature, rainfall, and wind significantly affect pollen levels. For instance, heavy rain can temporarily clear the air, but dry, breezy days can cause pollen counts to surge. (accuweather.com)
