A dark, ominous shadow moved across the water at North Cronulla on Wednesday, as a fast-moving blob showed just how quickly a tide can turn.
Sutherland Shire Council hosted a beach safety seminar during the busiest beach week of 2019.
It could not have come at a better time, as Sydney sizzles through days of sweltering heat, attracting thousands to beaches.
‘Science of the Surf’ at North Cronulla Surf Lifesaving Club was an educational talk that aimed to teach people during the school holidays about what do to if suddenly caught in a rip.
It was led by coastal geomorphologist, Rob Brander, a professor of biology, earth and environmental sciences at the University of NSW.
Dr Brander, nicknamed ‘Dr Rip’ by lifeguards, demonstrated the lively example of just how powerful ocean currents can be, by dumping purple dye into the water to show the rapid and often unpredictable movement of a rip.
Sutherland mayor Carmelo Pesce said the session was particularly important for children.
“Our lifeguards are extremely passionate about teaching young people about water and beach safety and have played an important role in the Science of the Surf sessions this year, as they do each year,” he said.
“Teaching kids about how to identify rips and what to do if they get caught in one is an incredibly important skill for life….no flags, no swim.
“Where there are dangerous conditions it’s really important to read the safety warning signs and ask a lifeguard or lifesaver if you have any questions.”
This week’s heatwave peaks Friday afternoon at a top of 33 degrees, made worse by high humidity. But the coast will benefit from a sea breeze.
