The Lowdown
Alright mate, Rusty here. Let's have a look at what's cooking for Shark Island (Cronulla) over the next couple of weeks.
We're in for a bit of a slow start, but patience is going to pay off big time. There's a solid run of decent surf on the horizon, with a couple of absolute standouts that will have the crew frothing. The water temp is about average for this time of year, nothing out of the ordinary.
First up, Thursday the 23rd is a write-off. Small, weak swell (104) coming out of the ENE, which is all wrong for this spot. That's a flat day, plain and simple. Friday the 24th is where we start to see a pulse. The morning looks promising with a clean 5ft south swell. The wind is light offshore from the southwest, so conditions should be pretty good, but the energy is moderate (430). Friday afternoon the wind swings onshore, turning it messy. Saturday the 25th has a similar story – a nice 5ft south swell in the morning with clean, cross-off winds, but the period is a bit longer at 11 seconds, giving it a bit more grunt (529). It's a good, solid day for the advanced crew, but the afternoon gets choppy.
Sunday the 26th morning is another strong contender with a clean 5ft south swell, good period, and that same light offshore flow. The energy is strong (552). This is shaping up to be a nice little run from Friday to Sunday morning, but it’s not the standout of the forecast.
Now, for the real action. The beginning of the following week is quiet again, but clear your calendar for Thursday the 30th of July. We’ve got a serious pulse of energy. The morning session will be massive – a 13ft south swell with a very long 12-second period. The energy reading is an enormous 7843, so this is a powerful, serious groundswell. The wind is fresh offshore from the SSW, so it will be clean. However, at this size, this is strictly for the expert crew only. It’s going to be heavy, and at a reef like Shark Island, it'll be a wild, challenging ride. The Friday the 31st morning is still pumping with a 10ft south swell and clean offshore winds, still very much an expert-only day.
If you want the best all-rounder for the more competent but not world-class surfer, jump on Saturday the 1st of August. The morning is looking prime: a 7ft swell from the southeast with a long 12-second period, light cross-off winds, and strong but manageable energy (1395). The swell direction is close to the optimum for the spot and the conditions will be clean. For the intermediate advanced surfer, this is your standout window.
After that, it drops back down but stays fun. Sunday the 2nd of August has a nice 5ft SE swell, clean and glassy early, with the wind going light offshore in the morning. A great session for competent surfers.
The following week is quieter with smaller surf and periods of onshore winds. The gem is Wednesday the 6th, which has a clean 6ft SE swell with cross-off winds. Into the second week, Friday the 7th of August morning looks clean again with a 5ft SE swell and glassy conditions, a nice way to round out the window.
So, to sum it up: the first few days are flat. Then we get a nice run from the 24th to the 27th. The big winner is Thursday the 30th for the experts, and Saturday the 1st of August for the best all-round, clean, powerful session.
Rusty.
