Drought in Ticino: summer 2026 at risk

Context

In brief

• April 2026 was extremely dry
• Risk of forest fires in Ticino
• Water reservoirs below seasonal levels

Key facts

• What: Drought situation
• When: April 2026
• Where: Switzerland, particularly Ticino and Graubünden
• Who: MeteoSwiss
• Amount: 10% of average precipitation

Despite the recent rains, the precipitation situation in the first months of 2026 remains well below average. April was historically dry, with very low soil moisture levels and an increasing risk of forest fires, particularly in eastern Switzerland and Ticino. In several regions near the Alps, including the Valposchiavo, there is a strict ban on lighting fires outdoors. According to MeteoSwiss data, the ground is dry to a depth of 40-50 centimeters, and water reservoirs are also below seasonal levels: in Graubünden, the fill level is around 10%, compared to an average of 20% for this period.

Immediate consequences

The drought situation has already led to immediate consequences, such as the ban on lighting fires outdoors in various regions. This ban has been imposed to prevent forest fires, which have already been reported in several areas of Ticino and eastern Switzerland. Furthermore, the lack of rain has led to a significant drop in water reservoir levels, with potential consequences for agriculture and water supply.

Future prospects

According to climatologist Thomas Schlegel, this April will likely rank among the driest since records began. The month was also about 2.5 degrees warmer than average and particularly sunny. The main cause is a persistent high-pressure situation over central Europe, which blocks Atlantic disturbances. A change is possible in May, with above-average precipitation expected between the 5th and 11th of the month. However, a prolonged phase of intense rain would be needed to compensate for the accumulated deficit.

Impact on Canton Ticino

Canton Ticino is particularly affected by this drought situation. The region, already subject to periods of drought, sees a further deterioration of water conditions. This could have a significant impact on agriculture and local water supply. Additionally, the risk of forest fires is high, requiring rigorous preventive measures.

Preventive measures

To address the situation, local authorities have implemented various preventive measures. These include the ban on lighting fires outdoors and awareness campaigns to reduce water consumption. It is essential that the population cooperates to mitigate the effects of the drought and prevent further damage.

Conclusion

The drought situation in Ticino and eastern Switzerland is concerning. It is essential to closely monitor weather conditions and adopt preventive measures to address the challenges posed by the lack of rain. Collaboration between authorities and the population is crucial to mitigate the effects of the drought and ensure adequate water supply.

Operational details

Analysis of the implications

The drought in Ticino and Eastern Switzerland has significant implications for various sectors, including agriculture, water supply, and land management. The lack of rain has already led to a drop in water basin levels, with potential consequences for agriculture and water supply. Additionally, the risk of forest fires is high, requiring rigorous preventive measures.

Impact on agriculture

Agriculture is one of the sectors most affected by the drought. The lack of rain can lead to a reduction in crops and a decline in agricultural production. This could have a significant impact on the local economy and the availability of agricultural products. It is crucial that farmers adopt measures to mitigate the effects of drought, such as using efficient irrigation systems and choosing crops more resistant to drought.

Impact on water supply

Drought can also have a significant impact on water supply. The lack of rain can lead to a drop in water basin levels, with potential consequences for the supply of drinking water. It is essential that local authorities closely monitor water conditions and take measures to ensure adequate water supply. This could include water rationing and awareness campaigns to reduce water consumption.

Risk of forest fires

The risk of forest fires is high in drought conditions. The lack of rain and high temperatures can create ideal conditions for forest fires. It is crucial that local authorities adopt rigorous preventive measures to prevent forest fires. This could include banning outdoor fires and awareness campaigns to reduce the risk of fires.

Preventive measures

To address the drought situation, local authorities have implemented various preventive measures. Among these, the ban on outdoor fires and awareness campaigns to reduce water consumption. It is crucial that the population collaborates to mitigate the effects of drought and prevent further damage. Local authorities must closely monitor weather conditions and take measures to ensure adequate water supply.

Conclusion

The drought situation in Ticino and Eastern Switzerland is concerning. It is essential to closely monitor weather conditions and adopt preventive measures to address the challenges posed by the lack of rain. Collaboration between authorities and the population is crucial to mitigate the effects of drought and ensure adequate water supply.

Key points

Concrete actions

To address the drought situation, it is essential to adopt concrete measures. Local authorities have already implemented various preventive measures, but it is crucial that the population collaborates to mitigate the effects of the drought. Here are some concrete actions that can be taken:

Reducing water consumption

Reducing water consumption is one of the most effective measures to address drought. Various practices can be adopted to reduce water consumption, such as using efficient appliances, repairing leaks, and reducing shower time. Additionally, rainwater can be used to irrigate gardens and plants.

Use of efficient irrigation systems

Farmers can adopt efficient irrigation systems to mitigate the effects of drought. The use of drip irrigation systems can reduce water consumption and improve irrigation efficiency. Additionally, cultivation techniques that require less water, such as precision agriculture and the use of drought-resistant crops, can be employed.

Monitoring water conditions

Local authorities must closely monitor water conditions and take measures to ensure adequate water supply. This could include water rationing and awareness campaigns to reduce water consumption. Additionally, advanced technologies can be used to monitor water conditions and predict precipitation.

Prevention of forest fires

To prevent forest fires, it is fundamental to adopt rigorous preventive measures. Local authorities can implement bans on outdoor fires and awareness campaigns to reduce the risk of fires. Additionally, advanced technologies can be used to monitor weather conditions and predict fire risk.

Collaboration between authorities and the population

Collaboration between authorities and the population is crucial to mitigate the effects of drought. Local authorities must clearly communicate preventive measures and concrete actions that can be taken. Additionally, awareness campaigns can be organized to educate the population about the importance of reducing water consumption and preventing forest fires.

Using the water consumption calculator

To help monitor and reduce water consumption, the water consumption calculator can be used. This tool can help calculate water consumption and identify areas where consumption can be reduced. Additionally, the calculator can be used to monitor progress and evaluate the effectiveness of the measures adopted.

Conclusion

The drought situation in Ticino and Eastern Switzerland is concerning. It is essential to adopt concrete measures to address the challenges posed by the lack of rain. Collaboration between authorities and the population is crucial to mitigate the effects of drought and ensure an adequate water supply. Using tools like the water consumption calculator can help monitor and reduce water consumption, contributing to mitigating the effects of drought.
