The Lowdown
G’day, Rusty here. Let’s look at what’s brewing for Shark Island (Cronulla) over the next couple of weeks.
Right now, we’re in a long, flat patch that stretches right through the first few days. From now until the morning of Friday the 7th, it’s barely a ripple – swell under 2ft, next to no energy. Water temp is 62°, pretty much what you’d expect for this time of year.
Friday the 7th morning finally coughs up a 2ft SSE swell with a clean offshore breeze, but the energy is still weak (107). It’s rideable, but don’t get your hopes up. Saturday the 8th morning is similar – 2ft from the S, glassy, but still nothing special.
The big moment – and I mean the only real standout – is Thursday the 13th. The morning delivers a solid 12ft swell from the S, with a massive 2443 combined energy. Winds are offshore from the SSW at 15 mph, so it’ll be clean. That’s expert territory – over 8ft means it’s for the experienced crew only. The period is 10 seconds, a proper groundswell, and this reef break can handle it. Just know that crowds can pop up here sometimes.
Friday the 14th morning still has some grunt – 8ft from the SSE with light offshore winds – but it’s fading. Still good for the skilled surfers.
After that, the swell drops off through the weekend and into the next week. Monday the 17th brings a 3ft ESE swell with a long 12-second period, but the wind is howling from the S at 22 mph, so it’ll be blown out. By Tuesday the 18th morning, there’s a clean 5ft SE swell with light offshore winds and moderate energy (362) – a decent option for a session.
Wednesday the 19th morning gives one last clean window – 4ft from the ESE with light winds – before it all fades again.
Bottom line: the first week is flat and frustrating. The big day to circle is Thursday the 13th – that’s for the charger. After that, a few clean, smaller windows pop up, but nothing to rearrange your life for.
Stay frothy.
Rusty.
