Pollen exposure is lasting longer and intensifying nationwide, though some areas are seeing sharper changes than others.
Pollen exposure is lasting longer and intensifying nationwide, data shows, as warmer temperatures take over more of the year. But for some areas, the changes are more dramatic.
Pollen seasons are not the same across the United States. Now, a report released by the nonprofit Asthma and Allergy Foundation of America shows where allergy sufferers had it the worst last year.

Most people check their local allergy forecast the same way every day. High, low, take an antihistamine, move on.
We’ve been spending a lot of time reviewing feedback, reading survey responses, and looking closely at how people are using Pollen Wise. One common thread amongst the feedback and survey responses stuck out: people want the app to feel easier to understand at a glance, and more helpful in answering the question, “What should I care about right now?” That thinking shaped this latest update. This is a major refresh to the Pollen Wise home screen, and while we know there is still more to improve, this update is an important step. We’re continuing to build, refine, and learn, and your feedback is a big part of what helps us decide where to go next.
Update: The data cutoff for legacy metrics data was changed from March 11 to March 23, 2026 6PM UTC. Data before that date will continue to be available for the forseeable future, however data after March 23, 2026 6PM UTC will no longer be present either in the legacy portal data viewer or via v1 APIs. Please use the V2 APIs and the Branch/Revision-powered data viewer in the portal for live incoming data
