Severe Weather Warnings

When a severe weather warning or advisory is provided by the local meteorological institute, we display it as a banner above the wind forecast.
The weather warning, for example a high wind warning, can help you prepare for dangerous weather conditions and avoid weather-related risks. The color scale indicates the intensity of the predicted weather event. For more details click or tap on the warning. General information about severe weather warnings can be found in our help section.
Please be aware that severe weather may occur without a prior severe weather warning being reported.

Units

We use knots and degrees Celsius as our default units. These units are often used by sailors, kiters, surfers, windsurfers and paragliders. Use website settings to switch between units and 7 different languages at any time. For converting between wind speed units such as knots, km/h (kilometers per hour), m/s (meters per second), and mph (miles per hour) use our wind speed calculator.
