So my parents came to visit and they were very excited about Switzerland. They wanted to see Mürren quite badly. Each day (they got here Sunday night) the weather forecast for Interlaken was partly cloudy. Each day we got up, it was cloudy and rainy. Even today as I look at Interlakens forecast showing "sunny", it is clouded over. Three different forecasts showing the same thing, all far from reality. Is this the standard deal, or can you ever count on the forecast in the Berner Oberland?

In short, probably not. The weather seems to change quite rapidly in Switzerland, with the mountains and all surrounding it. I guess that's why it is more difficult to predict. (any meteorologists out there, who can explain it better?)
Another thing I noticed is that on the meteosuisse website, the forecast tends to change if you change language. As if the different parts of the country have different forecasters.
Most of the time you are better off doing what you and your parents already did, look out the window in the morning!

No. Forecasting is like getting a winner in Lotto. A rule of thumb is -when the forecast says friendly it means a little less rain!

Go to the information created for people who really need to know what the weather is doing - pilots and sailors (although the former is obviously more applicable than the latter for Switzerland).



Low pressure over the Atlantic and lots of fronts coming across Europe from the sea with wind from the west is going to give us rain for the next few days.

A big area of high pressure over Europe will give you dry, stable weather.

Of course there's also the micrometeorology of the Alps to consider which will also affect local weather.

Why are you reopening an 8 year old thread?

It depends which weather model and data source was used to produce the forecast. A readily available and and cost free source used by manz apps is the US Global Forecast System https://www.ncdc.noaa.gov/data-acces...ast-system-gfs
. It has a grid resolution of 28 kilometers. This might be o.k. in open plains but not in alpine valleys where micro climate effects play a big role.

There are more detailed models such as the European ECMWF https://www.ecmwf.int/en/forecasts/d...on-and-support which has a resolution of 9 km. The German COSMO-DE from the Deutsche Wetterdienst has a grid resolution of 2.8 km https://www.dwd.de/DE/forschung/wett..._cosmo_de.html

More detailed is the COSMO-1 model by MetoSwiss https://www.meteoswiss.admin.ch/home...ng-system.html, it has a grid resolution of 1.1 km in the alpine region and provides forecasts for 33 up to 45 hours. A second independent source for a high resolution forecast for the Switzerland and surrounding region comes from Mr. Kachelmann which has its own Super HD Modell https://kachelmannwetter.com/ch/mode...126-1100z.html with 1km grid resolution.

In conclusion if you wan't precise forecast do not use the standard pre-installed free apps but something better.
MeteoSwiss is free of charge https://www.meteoswiss.admin.ch/home...swiss-app.html
The Kachelman Apps need a superscription https://kachelmannwetter.com/li/info...app-kachelmann but the website is free

8 year necro - well done.

Just a bump to prove my point about pressure charts and weather forecasting.

(and yes, I know it's an old thread)

Wow. That looks mean!!

Oh lol, you say that I have to much free time. (Does one ever have to much free time...? )

And here you are again digging up a many years old topic..

And oldie but a goodie!

Seems like these weather forecasters change their minds every hour. At least here it seems the case.

If you really want a good forecast, go to the source. If you go to google, Bluewin or Migros it's on you ?
