The Lowdown
Alright folks, Rusty here, and I’ve been staring at the charts for our corner of the coast, focusing on Shark Island (Cronulla). Let’s break it down.
The week kicks off with a bit of a mixed bag, but there are a couple of windows that’ll get the blood pumping. The real standout is shaping up for Thursday, July 30th, with a solid pulse of south swell hitting the reef. We’re looking at a meaty 8 ft swell from the south, with a 10-second period, and the combined energy is pumping at a strong 1957. That’s serious power. Add in a clean, moderate offshore breeze from the southwest, and you’ve got a classic Shark Island day – hollow, racetrack walls for the advanced crew. It’s a reef break, so it handles that long-period groundswell beautifully. The water temp is about average for this time of year, so no surprises there. Keep an eye on the crowds though, it’s a spot that can get busy.
Sunday the 26th is actually a nice warm-up, with a 6 ft south swell and a gentle offshore early. The energy is moderate at 753, and the morning session is clean and inviting for those who know the lineup.
Things go a bit quiet mid-week from Monday the 27th through Wednesday the 29th, with tiny, weak swell and poor conditions – a real lull. But then Thursday morning hits, and it’s game on for experienced surfers only.
Friday, July 31st sees the swell jump even bigger to 10 ft from the south, with a massive 2546 energy reading, but conditions are marginal due to some questionable tide. Still, for the die-hard crew, that’s a morning of heavy freight trains.
After that, the swell backs off gradually. Saturday, August 1st is still fun with a 7 ft south-southeast swell and clean offshore winds in the morning. Sunday, August 2nd offers another highlight with a 6 ft southeast swell, a long 11-second period, and glassy cross-offshore winds – that’s a beauty for a relaxed Sunday paddle, though the afternoon gets blown out.
The second week drops off hard. From Monday, August 3rd onward, we’re into small, messy, and mostly unrideable conditions, with a few brief windows of clean but tiny surf around the 2 ft mark. There’s a hint of a pulse on Thursday, August 6th – a 7 ft south swell – but with rain and strong winds, it’s just not worth the drive.
So, mark your calendar: Sunday morning the 26th for a clean warm-up, and absolutely Thursday, July 30th for the main event. It’s an advanced-wave zone on that day.
Rusty.
