The Lowdown
Alright, Rusty here again. Let's break down what's happening at Shark Island (Cronulla) in feet and knots.
Water temp is about 63°F, which is pretty normal for July.
Tuesday kicks off with nothing – a tiny 0.7ft south swell with weak energy. Don't bother. Wednesday the 15th is a big one but for experts only. A solid 10ft south swell rolls in with massive energy, but it's paired with a 19 mph cross-offshore wind. The period is 10 seconds. It'll be a wild, powerful ride, best left to the pros.
From Thursday the 16th through Tuesday the 22nd, it's mostly poor. Onshore winds, choppy surf, and swell sizes between 2ft and 6ft without any real quality. Thursday the 20th has a glassy morning with a 5ft east swell, but the quality is questionable.
Here's the one to get excited about. Thursday the 23rd of July, first light. We've got a 5ft east swell with an extra-long 14-second period (groundswell), pushing a ton of energy. That long period at Shark Island will produce clean, powerful lines. The wind is a light 9 mph cross-offshore from the west, keeping the surface smooth. This is flagged as "expect very good surf conditions," and it's your best bet by far. Afternoon winds kill it, so get out early.
The 24th has a similar 5ft east swell and clean morning wind, but it's only rated as marginal. The weekend of the 25th gets hammered by strong 25 mph southerly winds. Monday the 27th looks better with a light cross-offshore breeze and a 3ft east swell in the morning, but the real juice comes in the afternoon with a 6ft south swell and clean wind – could be a good sleeper session. The rest of the run into the 29th fades with smaller south swells.
Your best call: Thursday the 23rd of July, early morning. That east groundswell with clean offshore wind is the standout.
Rusty.
