The Lowdown
Alright, Rusty here. Let’s have a look at this stretch. We’re starting with a bit of a flat spell, but there’s a promising pulse of swell on the horizon that’s worth getting excited about.
The first few days are a bit of a write-off. Tuesday the 28th and Wednesday the 29th of July are offering nothing but tiny, weak waves – we’re talking under 2 feet with next to no energy. It’s a bit of a frustrating start, but hang tight, because things are about to change.
The real action kicks off on Thursday morning, the 30th of July. That’s when we see a solid jump in size. Shark Island (Cronulla) will be waking up to a clean 5 feet S swell at 9 seconds. The combined energy is moderate (303), and with a light WSW cross-offshore breeze, the conditions are looking clean. It’s not the biggest, but it’s a proper start.
Then, Friday the 31st of July is where it gets interesting. Friday morning delivers a punchy 6 feet S swell at 11 seconds, with a combined energy of 654. The wind is a clean cross-off from the SSW. This is a great window for the more experienced crew – the size is enough to get the heart pumping, but it’s still manageable.
But the standout of this whole forecast is Saturday morning, the 1st of August. We’ve got a 5 feet SSE swell, with a period of 10 seconds and a combined energy of 466. The wind is a light offshore from the SW, dropping to nearly glassy conditions by the afternoon. The water temp is about average for this time of year, so no surprises there. This is the pick of the lot – clean, punchy, and with a bit of size. The crowds can be a factor here sometimes, so get in early.
After that, Sunday the 2nd of August still holds some waist-to-chest high swell (4 to 5 feet), but the wind starts to turn a bit messy in the afternoon. We then hit a long flat spell from the 3rd of August right through to the end of the 16-day window. There’s a few tiny pulses, but nothing worth paddling out for. The energy just drops off a cliff.
So, to sum it up: the first couple of days are dead, but Thursday the 30th through Sunday the 2nd of August have some real fun waves on offer. Saturday morning the 1st of August is the absolute best bet – clean, offshore, and a solid 5 feet of SSE groundswell. Get out there.
Rusty.
