Being from a coastal location, we used to recommend a beach landing rather than the surf. However, sadly, a C150 with reported engine failure killed 2 people on a beach in Portugal last year. Instructor and student on board. They nearly got lynched by an angry mob.
In the case of our local beach, there are often more people in the water than on the sand - it's very popular with a number of surfing schools.
Major re-think required.
Sometimes the forced landing area chooses you, rather than you choosing it...
