Overview
Donnerwetter.de GmbH is a German weather forecasting company that operates the consumer weather portal Donnerwetter.de. The site is a broad weather-information destination, combining daily forecasts for Germany with live severe-weather monitoring, weather radar, lightning detection, nowcasting, rain scanners, webcams and satellite imagery. Beyond the core forecast pages, the portal organizes its content into thematic sections such as a weather magazine, news, specials, long-range forecasts, climate, renewable energy, a weather calendar and a weather lexicon. A distinctive feature of Donnerwetter.de is its range of specialized, life-oriented weather services. These include health-related bioweather (flu weather, cardiovascular, pollen, UV/ozone and tick weather), leisure forecasts (fishing weather, bathing lakes, football weather, garden and agriculture, ski and snow, wind) and travel/traffic services (airport weather, road weather and a frost/scraping forecast). The site also provides service tools such as website weather widgets, sun/moon data, e-mail weather and an online shop, alongside a "Wetterpark" section. The brand has a long history in the German online weather market: the portal marked its 30th anniversary, and the company has published a retrospective series looking back at its beginnings and key milestones. Donnerwetter.de GmbH is a private German company; it is not a listed entity. Its positioning is that of an independent, feature-rich German-language weather service aimed at consumers and niche audiences who need weather information tailored to specific activities and health conditions.
History
Donnerwetter.de GmbH is a German weather forecasting company that operates the Donnerwetter.de weather portal. The portal has been active in the German online weather market for decades and marked its 30th anniversary, at which point the company published a retrospective series looking back at the beginnings of Donnerwetter.de and highlighting key milestones. Over that period the service evolved from a weather forecast offering into a comprehensive weather-information platform. The modern Donnerwetter.de site combines general Germany forecasts with a wide array of live and specialist services. Its navigation includes current weather, weather radar, severe weather, lightning, reports, nowcasting, rain scanner, cameras, a star camera, and satellite imagery. Editorial and knowledge sections include a weather magazine, news, specials, long-range forecasts, climate, renewable energy, a weather calendar and a weather lexicon. A defining characteristic of the brand is its segmentation of weather information by life context. Health-oriented bioweather covers flu weather, cardiovascular conditions, pollen, UV/ozone and tick weather. Leisure forecasts address fishing, bathing lakes, football, garden and agriculture, ski and snow, and wind. Travel and traffic services include airport weather, road weather and a frost/scraping forecast.
