Crowds were riding the crest of a perfect summer day at Bate Bay beaches and Gunnamatta today.
Temperatures hovered around 28 degrees and the clouds stayed away.
The beaches are expected to get a lot busier with a scorcher of a weekend on the way.
Saturday is expected to reach temperatures of 29 degrees while Sunday is predicted to hover around 38 degrees.
Weatherzone meteorologist Graeme Brittain said a high of 43 degrees was forecast for both Liverpool and Blacktown on Sunday, and there was potential for the inner city to also hit 40 degrees.
After a hot Monday, predicted to be around 33 degrees, temperatures will drop to the low to mid twenties for the rest of the week with rain expected on most days.
Sutherland Shire Council will also host its popular annual Science of the Surf workshop this month with Dr Rob Brander from the University of New South Wales on Wednesday, January 17.
The session is at North Cronulla Surf Club at 2.30pm and it includes a multimedia presentation on how our beaches work and behave – from the massive swell that rolls in during big storms to how to spot a deadly rip current.
If conditions permit on the day, the session will be followed by a dye release demonstration into the surf at approximately 3.15pm at North Cronulla Beach which illustrate how a rip actually works.
Topics covered include beach safety and hazards, coastal evolution, wave formation, what safe and unsafe waves look like, how to spot rip currents and what to do if you’re caught in one, rock platforms and rock fishing and beach types and behavior.
