Understanding the Impact of Precipitation on Pollen Accumulation During Allergy Season

Pollen seasons are becoming longer and more intense due to climate change, leading to increased pollen concentrations and earlier starts to pollen seasons. (hhs.gov) Understanding how precipitation influences pollen accumulation is crucial for effective allergy management.

How Does Precipitation Affect Pollen Levels?

Rain can temporarily reduce airborne pollen by washing it from the air. However, this relief is often short-lived. Post-rain conditions can lead to increased plant growth, resulting in higher pollen production. Additionally, heavy rain can break larger pollen clumps into smaller particles, which are more easily dispersed by wind, potentially increasing pollen levels. (weather.com)

What Are the Phases of Pollen Season?

Pollen seasons typically progress through three phases:

  1. Tree Pollen (Spring): From February to April, trees like oak, birch, and cedar release pollen. (isitallergyseasonyet.com)

  2. Grass Pollen (Late Spring to Summer): Grass pollen peaks from May to June, with species such as Bermuda and Timothy grass being common culprits. (loyolamedicine.org)

  3. Weed and Ragweed Pollen (Late Summer to Fall): From mid-August to the first freeze, weeds like ragweed release pollen. (loyolamedicine.org)
