Geneva and Vaud launch heatwave plans as temperatures soar

Geneva and Vaud cantons are initiating their heatwave plans starting Thursday as Switzerland braces for a significant temperature increase, with forecasts predicting highs of up to 37 degrees Celsius by Monday.

The cantons are activating measures to protect public health during the anticipated period of intense heat, which is expected to last until at least Tuesday. Authorities are advising residents to take necessary precautions, stay well-hydrated, and show solidarity with neighbors and loved ones, particularly those most at risk.

Individuals particularly vulnerable to heat include young children under six, the elderly, outdoor workers, and those with pre-existing medical conditions. The cantons are providing advice through various online resources, reminding the public that heatstroke is a life-threatening emergency. Warning signs include high body temperature, confusion, general weakness, nausea, and cramps.

The activation of the heatwave plans follows specific meteorological criteria: average daily temperatures must be at or above 25 degrees Celsius for five consecutive days, or at or above 27 degrees Celsius for three consecutive days. MétéoSuisse, the national weather service, forecasts a gradual climb in temperatures, potentially reaching 37 degrees Celsius by Monday at the end of Lake Geneva.
