Allergies: questions people ask
Which pollen does Feelcaster track?
Tree, grass and weed pollen, from Open-Meteo and Google’s pollen data. Windy days carry it further, so Feelcaster counts wind in.
Why do thunderstorms matter for allergies?
Storm winds and rain can stir up pollen and break it into smaller particles, which some people feel more. Feelcaster counts storms for more when pollen is high.
