This page is about asthma and allergy forecasts throughout the country. Allergens like pollen can infiltrate homes and affect indoor air quality.

Relevant variables for this topic include pollen count and allergy risk.


Asthma and Allergy Forecast
The Asthma and Allery Forecast’s Allergy index consists of weather factors and plant growth stages that increase the release and spread of pollen. High pollen count and/or spread is represented by a higher index value. The Allergy index offers customized present-day pollen for any area.

The Weather Channel’s Allergy Tracker 
The Weather Channel’s tracking tool follows the daily pollen count and the 15-day allergy forecast, which predicts the risk of allergy symptoms. The tracker also covers the breakdown of specific pollens, such as tree, grass, or ragweed pollen. It tracks the pollen level for each specific pollen and provides a 3-day outlook for the worst offenders. The Allergy Tracker informs the public of days of increased pollen count and what weather conditions that increases those levels. The increase of pollen can affect the number of allergens in a home. The Allergy Tracker allows residents to make informed decisions on minimizing indoor activities such as ensuring windows are closed and AC units or HEPA purifiers are used to filter out allergens.
