Anyone know where you can hire a surfboard in Lagos, Port.

Me and my girlfriend had a deal - I'd teach her how to snowboard, and she'd teach me how to surf. I've held up my part of the bargain, and we are planning to stay in my parents villa in lagos, Portugal in autumn so she can repay the favour. Only problem is that neither of us own boards, and money's a bit tight, so we wanted to see if we could hire some. This will be my first visit, so I don't really know the area that well - could anymone recommend some decent beaches, and a place where we can get hold of some boards? Help!!!!
