WetterOnline

What WetterOnline does

WetterOnline, founded in 1996 and headquartered in Bonn, Germany, operates one of the largest digital weather information platforms in German-speaking Europe, serving approximately 35 million regular users. The company delivers forecasts, real-time radar visualizations, severe weather warnings, and 14-day outlooks through its wetteronline.de website, native iOS and Android applications, an Amazon Alexa skill, and an embeddable weather widget. Its technology stack combines proprietary radar products (RegenRadar, WetterRadar, TemperaturRadar, WindRadar, BlitzRadar) with predictive forecasting algorithms, anchored by a 90-minute nowcast and an extended two-week outlook, drawing on an extensive Central European weather station and observation network.

Beyond the free consumer platform, WetterOnline operates a Profi-Wetter section serving professional users with model forecasts, satellite imagery, and specialized content modules spanning pollen forecasts, UV index, snow depth, sailing weather, river water levels, water temperatures, and live webcams. The company has also extended into hardware through the WetterDisplay physical weather display device sold via shop.wetteronline.de. Revenue is generated through three streams: display advertising on the free consumer properties, hardware sales of the WetterDisplay, and quote- or subscription-based professional B2B weather services. The company employs approximately 160 people across offices in Bonn and Bornheim, and its platform extends geographically across Germany, Austria, Switzerland, and most of Europe, with additional portals reaching North and South America, Asia, Africa, and Oceania.
