BAFU Warns of Forest Fire Risk Due to Drought
Several Cantons Implement Precautionary Measures
The Federal Office for the Environment (BAFU) warns of persistent drought and an increased risk of forest fires. The forest fire danger is currently elevated in large parts of Switzerland. Several cantons are particularly affected, where authorities have issued precautionary measures. The situation is reminiscent of previous hot summers but remains dynamic. The responsible bodies will closely monitor the situation in the coming days.
Drought conditions have increased in recent weeks. According to BAFU, the forest fire risk varies regionally. The second-highest warning level is already in effect in some regions. The forest fire danger is indicated on a five-level scale; Level 3 signifies a considerable danger. The responsible cantonal offices are closely monitoring developments. Fire departments and forestry services are on heightened alert. The danger is assessed based on weather data, soil moisture, and wind conditions.
According to authorities, areas with prolonged drought and high sun exposure are particularly affected. Wind also plays a role. Authorities recommend checking the local situation before lighting any outdoor fire. Cantons publish their warnings on their websites and in apps. Current rules can also be found there. At Level 4 or 5, additional prohibitions apply in many cantons.
Cantonal Measures
Several cantons have prohibited lighting fires in forests and near forest edges. Grilling at open fire pits is also only allowed with a permit in many places. Some municipalities have additionally forbidden smoking in forests. The police monitor compliance with these prohibitions. Violations can result in fines. The amount of the fines varies by canton. The prohibitions generally remain in effect until further notice.
BAFU calls on the public to adapt to the conditions. It recommends refraining from open fires and properly disposing of flammable waste. Cigarette butts do not belong in nature. Even a single spark can trigger a forest fire. Parking on dry grass is also considered a danger, as hot catalytic converters can ignite fires. Lighting fires near buildings is also restricted.
Authorities also recommend refraining from using fireworks outdoors. Disposing of glowing ash in nature is also prohibited. Temporary fire pits are not permitted in many regions. The cantons point out that Christmas tree and garden waste must not be burned either. Those who are unsure can inquire with their local municipality.
Conduct in Forests
Those planning outdoor activities should check the current forest fire danger level beforehand. Cantonal authorities publish current warnings on their websites. Weather services also provide information. For planning excursions, checking official channels is recommended. In case of suspected fire: immediately dial emergency number 118 and leave the area. The emergency number is available around the clock. Further tips can be found in our Forest Fire Guide.
Forest protection is in the public interest. Forests fulfil important functions for humans and biodiversity. A fire can destroy large areas and affect regeneration and water balance. Reforestation after a fire takes decades. Therefore, authorities appeal to everyone's personal responsibility. Anyone who notices smoke should not hesitate to alert emergency services.
Outlook
The situation can change rapidly. Rainfall would reduce the danger, but weather forecasts are uncertain. BAFU and the cantons remain in contact and continuously adjust warnings. The public should follow these announcements. Information on current forest fire danger levels can also be found on the Environment Topic Page. Also read our report Summer 2026. The coming days will show whether the situation eases.
