Hi Joni
We've had a couple of month-long trips to Portugal, inspired by the recent selected climbs guide, and visited almost every crag in the book.
We really enjoyed the whole Portuguese experience - cragging, culture, people, coastline. You'll find photos and crag beta, plus some trip-planning info for all the areas on the blog https://rockaroundtheworld.co.uk/category/portugal/
The Portugal select guide is really good but a bit quirky (not great on crag approaches but there are some directions on the blog for places we struggled to find)
Depending what time of year you are planning to visit there's a good choice of high or low altitude and orientation of crag. We've had a couple of months there, but jan/Feb so Autumn would be a different kettle of fish. A few highlights below:
The Serra da Estrela is the obvious spot (we were really lucky to get anything done in winter - it's high up and faces all directions so should be comfortable.) https://rockaroundtheworld.co.uk/2020/02/14/serra-da-estrela/
Sea cliff wise then I'd suggest Sagres (as mentioned above) as the best base. Lots of options for trad and sport and different orientations so you can chase the shade.

There's another good concentration of spots around Lisbon and Sesimbra - there are certainly west-facing options at both and you could chase shade there. https://rockaroundtheworld.co.uk/2020/02/05/sesimbra-velha/ Sintra is a good bouldering and granite trad venue too.
Fab country, friendly people, great food - enjoy!
Get in touch via pm if there's anything else I can help with. Have a great time!
