Lake Sarnen: Weather Today

📅 Tuesday, August 4, 2026
Today is definitely not a day for the beach, so it is best to make alternative plans indoors. The weather is unsettled and potentially hazardous, with strong thunderstorms likely to roll through the area throughout the day. You should expect heavy rain and intense wind conditions that will make sitting by the water uncomfortable and unsafe. While the air temperature will feel warm at 31.8 °C, the risk of storms and rough conditions overrides any benefit from the heat. Additionally, the UV index is high at 6.9, meaning sun protection is necessary if you are outside, though the heavy cloud cover will provide shade. Please stay away from the shore until the weather stabilizes and the risk of lightning and strong winds has passed.
