The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Shark Island (Cronulla) over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. We’ve got a few days of nothing much happening, with poor conditions and cross-off or onshore winds messing things up. The first real glimmer of hope comes Thursday the 27th of August, with a 6ft swell from the south (moderate wave energy of 600), but it’s crossed up with a light SE breeze, so it’s only marginal. The water temp is sitting at 63°, which is pretty much normal for this time of year.
Now, the standout session is going to be Friday morning, the 28th of August. We’ve got clean conditions with a light offshore wind from the SW, a 5ft SSE swell running at 11 seconds, and a solid 662 combined energy – that’s got some push. This is a reef break and it’s fairly exposed to the swell, so that long period groundswell will wrap in nicely. Keep in mind it’s an advanced wave, so this isn’t for the grommets. It’s a fairly consistent spot, but crowds are possible, so get in early.
Saturday morning, the 29th of August, is also worth a mention. Another clean morning with a glassy SSW offshore breeze, 4ft SSE swell, and 639 combined energy. The swell is a touch smaller than Friday, but the conditions will be just as good. It’s a solid second option.
After that, things get a bit ordinary again. We get a few more marginal sessions, but nothing really firing until the tail end of the run. Around the 9th of September, we see a 5ft S swell with a light cross-off wind, but it’s a short period at 7 seconds, and the energy is only moderate at 259. It’s surfable, but nothing special.
Overall, your best bet is Friday morning the 28th of August. The swell direction is a bit south of the optimum (which is SE), but the offshore wind and decent size make it the pick of the bunch. The long period at 11 seconds means better shaped waves, but it could be a bit straight at times, so pick your line.
Rusty.
