Three of us went out in the boat, skimming over the tops of waves, which put a permanent smile on my face.
As the day went on it became clear that being a lifeguard at Riversdale was more than just tending to first aid or getting a tan. It is about immersing yourself in the culture of the club and giving back to the community.
"I started Nippers at Riversdale when I was 5," Mr Hepburn said. "So pretty much since I can remember I've been coming out here. I did Nippers up until I was 14, and that's when I became a lifeguard.
"We're about 40 or 50 minutes away from the nearest ambulance, so we really have to have sharp first-aid skills as opposed to other beaches, which have ambulances 10 minutes away.
"So we're the first point of call, really, for anything close to Homewood area. If there's a crash on the road, the siren will go off and we'll boost out to that."
Mr Hepburn said the only downside was "not being able to surf when it's like this", gesturing at the picture-perfect waves.
The next big event for Riversdale is the Nipper carnival on January 24.
Until then, these dedicated lifeguards will be on patrol every day from 9am until 6pm.
