Pollen Season is Here: What You Can Expect Heading Into the Spring

You are not imagining it if you have noticed more allergy symptoms in recent days. Tree pollen season is underway across some areas of the southern and western U.S. Meanwhile, grass pollen levels are forecast to reach their peak later in the spring and early summer. Weed pollen will be another issue to deal with for some allergy sufferers in the months ahead.

How does weather impact pollen season, and when and where will the allergens be the worst this year? Read on for a look at what the experts are saying about the upcoming allergy season in the U.S.

How the Weather Impacts Pollen Season

A number of weather factors affect how the pollen season will unfold. Temperatures, wind speeds, rainfall, and the presence of late-season frost events all impact the timing and severity of the pollen season. For example, warmer temperatures close to the surface of the ground encourage plants and trees to generate more pollen.

Likewise, a big rain event works to wash away pollen temporarily. However, drier days immediately after the rain send pollen levels soaring once again.
