Hi shoupster, and welcome to MySwissAlps!
If you are appropriately dressed, Switzerland is not too cold to enjoy at any time of the year.
However, it will be getting decidedly chilly in higher-altitude towns and villages by the beginning of October, with the chance of light snowfalls (which will usually melt within a day or two at that time of year).
If you would prefer warmer weather, I would suggest you move your trip forward to begin in the first week of September. That is a particularly good time to be in the Jungfrau Region, where you are spending most of your time.
You can find out more about the weather here:
