The horizontal resolution is 7 kilometers. The Superforecast is updated 4 times per day. Predictions are available in time steps of 1 hour for up to 3 days into the future.

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.
