Pollen Atlas

Pollen Atlas publishes daily pollen counts and 5-day forecasts for US cities. A Total Pollen Index from 0 to 100 comes with tree, grass and weed breakdowns and the dominant allergen, and a worst-city ranking shows where levels are highest. There is also a US pollen map, an air quality section, a news section and a Find an Allergist section.

Pollen Atlas is a website only. Pricing is not stated on the site. Data is credited to WeatherAPI and the Google Pollen API.
