Sits right at the São Martinho bay mouth/channel — more exposed than the inner bay, so it can produce fun beginner-to-intermediate peaks when the channel sandbar lines up.

Shared forecast The offshore forecast here is shared with São Martinho do Porto. Wave models resolve about 8 km, so neighbouring beaches read the same swell. What separates them is orientation, seabed and tide, not the forecast.
