Switzerland’s Drought Deepens: A Looming Crisis as Heat Persists
As the summer of 2026 progresses, Switzerland is facing a rapidly worsening drought situation. The spring season has been significantly drier than usual across much of the country, and the recent weeks of hot, dry weather have exacerbated the problem. According to the latest reports, the drought is now taking on historic proportions, with severe implications for the environment, agriculture, and water resources.
The signs are unmistakable. In Graubünden and Ticino, the risk of forest fires is already moderate to high in many areas. Snow cover in the mountains is well below the long-term average, and reservoir levels are critically low. Lake levels and river discharge are also significantly below normal, putting pressure on ecosystems and water supplies. With no significant precipitation expected in the next two weeks, the situation is set to deteriorate further.
Meanwhile, the heat shows no sign of relenting. The south of Switzerland remains hot, and although National Day (August 1st) may bring slightly cooler temperatures and increased humidity, the overall trend is one of persistent heat. This summer is already being compared to the infamous heatwave of 2003, with higher average temperatures, more days of extreme heat (35°C and above), and a greater number of tropical nights (minimum temperatures above 20°C) recorded across many regions.
The combination of drought and heat is a stark reminder of the challenges posed by climate change. As the country grapples with these extreme conditions, authorities are urging caution and preparedness. The coming weeks will be critical in determining the full impact of this crisis, and it is clear that Switzerland must adapt to a future where such events may become more frequent and severe.
