Allergy Tracker Tool & App

Get Your Local Allergy Forecast Now

Some days your allergies might feel worse than others. Even if you take ZYRTEC® as recommended, you might want to avoid triggers or prolonged periods outdoors if the pollen count is high in your area.

Wondering how today’s pollen forecast will affect your seasonal allergies? Use our Allergy Forecast tool to check today’s pollen counts, predominant pollens in the air and weather near you. Enter your ZIP code to get started.


This pollen tracker helps you determine how the pollen count could affect your allergies. Unlike static maps and figures, ALLERGY IMPACT analyzes weather information from 41,000 ZIP codes, as well as search-engine and social-media trends, to tell you how the pollen count might make you feel.

How to Use This Tool

If the ALLERGY IMPACT number is higher than the pollen count number, you might feel more prone to sneezing than you'd expect. If it's lower, you might not feel as bad compared to what you’d expect.
