After the coldest January for 30 years, temperatures across Switzerland rose dramatically on Thursday, reaching 16 degrees in some parts of the country.
A strong foehn wind was responsible for bringing temperatures up to 16.4C in Evionnaz in the Valais, said MeteoNews
in a statement.
Buchs in the canton of St Gallen and Schattdorf in Uri also surpassed 16C, while temperatures were generally in double figures across the country's lowlands.
The strong foehn reached a maximum of 101km/hr at Les Diablerets in the canton of Vaud, it added.
However the warm spell is not a record-breaker for the month of February. That was set in February 1998 when the mercury rose to a summery 21.7C.
The foehn wind is a special feature of the Swiss climate and occurs mainly between autumn and spring, according to MeteoSuisse.
It generally produces mild and dry conditions and high wind speeds.
The foehn is a stark contrast to the cold bise wind that is another characteristic of the Swiss weather and was responsible for a particularly icy spell in January.
