Here we display the weather development for the next 7 days. Click on a tab to view a detailed day forecast. You can also use the keyboard arrow keys to navigate through the days, or if you use a touch screen, you can use the swipe function. Each tab includes a pictogram with the weather condition, maximal and minimal temperature, dominant wind speed and wind direction, the precipitation amount for 24h in mm and the sunshine hours. If you move your mouse over the logo for sunrise and sunset, also the current UV index is displayed. Normally, the maximum temperature is expected at late afternoon and the minimum at night.

The 3-hour overview shows a more detailed forecast for the selected day:

• The top-left shows sun and moon rise and set times. The moon-phase is also displayed as a small image.
• The 3 hour values are calculated as follows: temperature and wind show the condition at the displayed time. They are not mean, max or min values.
• Precipitation is accumulated and shows the amount accumulated during the previous 3h in mm. It behaves like a rain gauge."5 mm at 12:00" shows the precipitation amount from 9:00 to 12:00.

Click on additional parameters to extend the forecast by the following parameters:

• The 3-hour values are extended by felt temperature, wind gust and relative humidity. The temperature felt is calculated with wind speed, solar radiation and humidity, and therefore includes both windchill and heat index.
• If available, we also include an hourly weather forecast below. The first row displays the hour, the second temperature; the following rows are wind direction, wind speed and gusts.
• For coastal areas, we show sea temperature, wave height and period. Note: Wave information for Mediterranean, Baltic and Red Sea will be added soon.

In addition to these parameters, our forecast system includes much more data. We calculate various forecast models with 55 atmospheric layers and a spatial resolution from 25km down to 700m. Each day, we generate terabytes of data and have built one of the largest weather databases on Europe. This enables users and customers to find pertinent weather information for every place on Earth. The available data and images can be obtained as "Products" through our Business Services.
