Each Spring, AccuWeather's team of expert meteorologists, lead by Senior Meteorologist Alan Reppert, analyzes forecast data, weather patterns, and climate research to project what allergy season will look like — including whether it will be extended or more intense than usual.

How long and how severe a pollen season will be depends on these forecasts, weather patterns, and climate research. Different pollens dominate at different times: tree pollen leads off in spring, followed by grass pollen in summer, and weed pollen in late summer and early fall. Warmer, windy, and dry days amplify allergy symptoms, while rainy and windless days reduce airborne pollen. Drought conditions can also limit grass and weed growth, lowering pollen counts overall.

The AccuWeather app can monitor and forecast specific allergens in a given area — including tree pollen, ragweed, grass pollen, and mold — helping people plan their days around allergy exposure.

For businesses specifically, AccuWeather offers a more advanced layer: AccuWeather and its subsidiary Plume Labs combine forecasting and air pollution expertise to deliver superior air pollution forecasts, warnings, and insights. AccuWeather monitors specific asset locations around the clock, sending site-specific, proactive notifications of unsafe air quality conditions through its SkyGuard® warning system within the AccuWeather For Business Portal and Mobile App.
