There was a website that was my favourite one to check as I walked along the Camino. I could see what predicted temperatures were, what the likelihood of rainfall was etc.

There is also a page on the site that summarises weather, on a monthly basis, for several points along the Camino.

However, averages do not always apply: as one who is not overly fond of walking in too much heat, I was quite pleased to end up walking this June although the locals seemed to be complaining it was much colder than normal!
One other thing about walking in November that you may already be aware of... not all albergues are open all year... quite a few are seasonal, and will close by the beginning of November.
