Hey Torben,
I stayed in Peniche last year at october, it's a fishing town at a peninsula. It's about 100 km far from Lisboa. There are always surfers around, so I think you'll have enough companions to socialize with. It's a very well-known surfer-place. They have great conditions there - nearly all year long, as far as I know. Advanced surfers like the spot for the tube-waves, but beginners like you will feel comfortable there as well. They have a great range of waves around the place - so also easy and fun ones for beginners. There are a lot of surfer schools around, if you want to make a course. I stayed there about two weeks, and every day some of the surf spots offered good conditions. A guy from the school there told me, that they have just a very few days in a year, where really no surf spot has the right conditions to surf.
I stayed with some friends at a holiday home from Casamundo, but they have camping sites, too, check out
cm-peniche.pt to find out more.
And about the place and its sights you can find some more information
here. Maybe it's something for you

Wow, I am jealous that you can stay there for three months
