Meteorologist Thomas Bucheli reports that the current heatwave in Switzerland is an extraordinary event, contradicting claims that such heat is common. Analyzing Luzern’s temperature records since 1886, Bucheli noted a significant increase in years with over 15 heat days since 2003 compared to the period between 1886 and 2002.
Why is the current heatwave considered unusual?
Bucheli addressed claims that similar heat periods have occurred regularly in the past. Using continuous temperature data from Luzern, he argued that the current conditions aren’t typical. He stated that the frequency of extreme heat has shifted significantly in recent decades.
“There is no one who can say: I have experienced this before!”
The data shows a clear distinction between historical patterns and recent years. Between 1886 and 2002, only three years recorded more than 15 heat days. Since 2003, however, eight such years have already been registered.
What do the historical temperature records show?
Prior to the current period, the highest record for heat days was set in 1947. The current heatwave could potentially surpass previous benchmarks. If the high temperatures persist until the beginning of next week, Luzern is likely to set a new record for the month of June.
