On Tuesday (16 October), the mountains facing our flat had snow-covered peaks. For instance, this is how the place I had been to on Saturday looked like under the snow:
However, Friday (19 October) saw a sharp reversal, which was attributable to a warm and dry wind descending from the mountains, called foehn (more here). So that the 29C mark was hit in Vaduz (in neighouring Liechtenstein) and almost reached in Altdorf (canton of Uri, 28.6C according to SwissMeteo – see map) and in Buchs (canton of Sankt Gallen- according to MeteoNews.)
What is more, the temperature at the summit of Moléson, the iconic mountain of the Fribourg Alps in Gruyères (altitude 2,002m), even reached a record for October: 19.8 degrees Celsius. Which means that on top of the mountain, it would have been as warm as when we went to visit the Château de Gruyères below in the valley early June of this year!

With this spell of warmer weather predicted to last until tomorrow, this certainly bodes well for any mountain trips we might take.
It also makes me wonder whether we shall be enjoying this year too warmer weather in November — early that month last year there were places where the temperature did not drop below 19.7 degrees at night (at Glaris, canton of Glarus) …
Conclusion: the weather is really becoming more and more erratic these days!
