Now

Weather in the valley

Schwyz (480 m). Past hours are measured at the MeteoSwiss station; the forecast takes the finest weather model available for each hour (ICON-CH1, ICON-CH2, ICON-D2, then ECMWF IFS).

Rivers and lakes

Measured values (BAFU) next to our forecast. The band holds 80 % of the expected outcomes.

Smaller streams

These have no gauge in the model. They are rough estimates: a fixed share of the Muota flow.

Valley fog

Chance of fog or low stratus over the valley floor between Schwyz and Brunnen.

How good are the models?
