When is waterfront lifeguard training offered?
No, not usually. what you can do though is take your regular lifeguard class and try to get a job at a pool (this is a better job in the off season trust me) then once you have some experience go talk to whoever runs the beach or lake. My friend was able to get her waterfront training cut rate because the head guard at the beach she wanted to work at was willing to train her on the cheap, she got a job there the same day as she started training.
