Context & protective measures
Background: dry spells are becoming more frequent and longer in Switzerland. Prolonged drought lowers groundwater and spring levels, strains the drinking-water supply of smaller municipalities and agriculture, and markedly increases the risk of forest and field fires. The FOEN rates the situation by region across several warning levels.
Recommendation
The likelihood is low, but the impact is high. Use the linked guide to prepare in a targeted way.
What to do now
Use drinking water sparingly, observe municipal water-use restrictions and fire bans, avoid open fires and barbecuing in the forest, and keep a drinking-water reserve.
