What Factors Influence Pollen Levels?

Pollen levels are primarily influenced by weather conditions such as temperature, rainfall, and wind patterns. Warmer temperatures can lead to earlier and more intense pollen releases, while rainfall can temporarily reduce pollen counts. However, dry, breezy days can cause pollen levels to spike.
