The temperatures are extremely dependent on altitude.
Sun vs. clouds can add to that effect, or subtract.
In the Jungfrau region you could search for annual average temperatures at Interlaken, Lauterbrunnen, and Jungfraujoch. If you add Kleine Scheidegg, you get an altitude that is high but not up at the Jungfraujoch.
Indoors is different, obviously, which as noted is relevant to the Jungfrau.
and other sites available on the internet will help you out.
