Hi fella. First off, sorry about the site being so quiet. Social Media seems to have ruined everything. OK the guy to ask is Marc from Blast Kiteboarding. The expert on all things Portugal. He does regular trips with groups. Either PM him thro here or contact him thro his website. On here he uses the name BLAST but as a noob Id message him on FB. Sorry, I couldnt be any more helpful. Its a place Ive never been BUT Im guessing, from what Ive read, its light wind thro summer so depending on your weight, if around 70 or 80k, a 12 to 14 and a 9 I would have thought.
