kachelmannwetter.com
Kachelmannwetter.com is a German-language weather platform built for people who want detailed radar, forecast models, storm tracking, and weather data instead of a simple daily forecast.
What is Kachelmannwetter.com?
Kachelmannwetter.com combines current observations, weather forecasts, radar images, satellite data, lightning detection, climate records, and numerical weather models in one website.
The service is operated by Kachelmann GmbH, which is part of the Kachelmann Group and is led by meteorologist and entrepreneur Jörg Kachelmann.
The wider Kachelmann Group develops weather technology for consumers, companies, energy businesses, and severe-weather monitoring.
Why does the website show so many weather models?
Kachelmannwetter.com lets users compare forecasts instead of presenting one computer model as the only possible outcome.
Its model comparison includes major systems such as ECMWF, ICON, GFS, UKMO, GEM, AROME, and several Kachelmann-developed models.
The company's Super HD model reaches a grid resolution of about 1 by 1 kilometer, which can show much more local detail than large global models.
The Kachelmann Group also says it has developed an UltraHD city model with a grid as small as 100 by 100 meters for specialized applications.
High resolution does not automatically make every prediction correct, because rainfall and thunderstorms can still develop differently from what a model calculates.
How does Kachelmannwetter.com handle forecast uncertainty?
The site's XL forecast compares several model predictions for the same location so users can see when forecasts agree or disagree.
Closely grouped model lines suggest a clearer trend, while widely separated lines show that the future weather pattern is less certain.
This approach gives users more information than an app that simply displays one rain icon or one temperature number.
What can its weather radar show?
The German radar service uses a 1 by 1 kilometer grid and provides updated radar imagery every five minutes.
Its German radar archive reaches back to 1993, although the company warns that some historical periods can contain missing images.
Users can also view storm movement, hail information, flash-flood tools, satellite imagery, and radar products designed for severe-weather analysis.
This makes the website especially useful when users need to know what is happening now rather than only what a forecast predicted hours earlier.
Can Kachelmannwetter.com track lightning?
The lightning analysis uses a network of receivers to locate electrical discharges and displays detected strikes on detailed maps.
Kachelmannwetter.com says lightning records for Germany and several nearby countries can be searched back to 1999.
The system also provides information such as strike polarity and estimated electrical current where the underlying data supports it.
How much historical weather data is available?
Kachelmannwetter.com says its observation tools draw on data from more than 14,000 weather stations worldwide, including official and supplementary station networks.
The site also provides ECMWF ERA5 reanalysis maps that allow users to study past storms, heat waves, temperature patterns, and other weather events back to 1950.
ERA5 maps on the platform use roughly a 30-kilometer grid and represent the atmosphere through 137 vertical levels, so they are designed for broad historical analysis rather than street-level conditions.
Is Kachelmannwetter.com free?
Much of Kachelmannwetter.com can be used without paying, while subscriptions remove advertising and unlock additional tools.
As of September 2026, the site's subscription page lists an ad-free plan at €4.99 per month or €49.90 per year.
The Plus subscription is listed at €6.99 per month or €69.90 per year and adds features such as extended model parameters, animation players, ensemble heatmaps, longer-range products, and weather API access for supported private uses.
A separate business subscription is offered for commercial use because normal consumer access does not automatically grant companies permission to reuse the site's services commercially.
Who will get the most value from Kachelmannwetter.com?
Kachelmannwetter.com is most useful for weather enthusiasts, photographers, outdoor workers, travelers, farmers, storm watchers, and anyone who wants to inspect the data behind a forecast.
Casual users may find its many maps and parameters more complex than a basic weather app, but that complexity is also the website's main advantage.
Instead of hiding uncertainty behind one forecast symbol, Kachelmannwetter.com gives users radar, observations, competing models, and historical evidence so they can see how the weather picture was built.
