Default GFS Reliability

I was wondering how far ahead the GFS pressure, temperature & rainfall
charts can be relied upon. The reason for the question is that we're off
on our Holidays to Switzerland in August and the Gfs charts seem to be
suggesting a much improved outlook which quite frankly i'm desperately
hoping is correct. I had read somewhere that the charts up to +240 can be
considered fairly accurate but become rather fanciful after that.

If someone could advise me please that would be great.

Many thanks



Well in my humble experience over a decade now, I find the various models
are far better in accuracy with bland boring weather that they are with
exceptional scenarios ; especially in the winter.
