i'm fairly sure i'm not a *real* SURFER... I like recreational bodyboarding and kayaking 
What's a *real* SURFER when one is at home? 
To be fair its the occassional water user that is at most risk. If you are not a member of SAS or other water user organisation then you do not have access to information about safe bathing waters.
In your own best interests to join something like SAS.
