This is a collection of photos that I have taken over the years in different conditions to give you an idea of what to expect during each month (or at least to show how variable it can be). I don’t take many photos in bad or dull weather, so this is a bit biased to showing sunny conditions. The height is given for where the photo was taken from..
If you want more of an idea how it might look at a certain location then many of the webcams at Roundshot have an archive letting you see how the conditions were on any day over the last few years.
Firstly just to show how pointless this can all be: below are two webcam screen grabs of Männlichen around the 21st of May, but in very different years.
The height of ski season in the mountains, whilst things are just a bit grim/boring down below.
The snow will start to recede and flowers will start to pop up low down (but it will still mostly be grim).
Ski season comes to and end in the higher resorts and by the end of the month all the lower lying areas will be green with flowers everywhere, as for the places in between they will be a bit sad sitting between the seasons. What happens weather wise is anyone’s guess; it might be a glorious heatwave, or it might be freezing rain.
There will still be patches of snow higher up, but mostly it is giving way to green meadows.
Temperatures start to drop and the days are getting shorter. The high meadows will clearly be turning brown and fresh snow will appear on the mountains.
Many lower lying areas will often be sat in the fog from the start of October until early into the new year.
This is a very hit and miss month. The last of the autumn colours will fade out at the start and after that it might be snowy in the mountains with some early openings for ski resorts, or it might just be grim everywhere.
Ski season starts early in December, but in recent years there might not actually be any real snow to meet it.
