The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next few days are a write-off. We’ve got a real slow start, with nothing worth paddling out for until Thursday, July 30th. That’s a solid three-day gap of flat, weak, or just plain messy conditions. But once we hit that Thursday, there’s a quick window of proper surf before it fades again.
The standout session is Thursday morning, July 30th. Shark Island (Cronulla) will be firing with a solid 6ft swell from the S. The wind is light offshore from the WSW, a light breeze, so the face will be clean as a whistle. The combined energy is strong (827) – you’ll feel that push. It’s a reef break, and with that size, it’s for advanced surfers only; the waves will have some punch. Water temp is sitting at 63°, which is about average for this time of year, nothing to complain about.
Friday morning, July 31st, is also a cracker. Another 7ft S swell, with a cross-offshore breeze from the SSW. The energy ramps up to very strong (1232). Again, this is a big setup – only for the experienced crew. Crowds are sometimes a thing here, so expect a few locals out, but the quality should be worth sharing the lineup.
Saturday, August 1st, eases off a touch. The morning sees 4ft from the SSE with a light offshore. The afternoon turns glassy – a dead calm E breeze at 3 mph, which is a major positive. Energy is moderate (370). It’s a good, clean option if you want something a bit more mellow.
From Sunday, August 2nd onward, it’s a slow fade. The swell hangs around 3ft to 4ft for a few days, but the wind gets messy – cross-shore and cross-onshore, spoiling the shape. By Wednesday, August 5th, there’s a brief spike of 6ft from the SSE, but it’s a short-period (6 seconds) windswell, which won’t hold much power. The energy is still moderate (282), but the afternoon wind turns onshore and ruins it.
After that, the second week is a bit of a blur. The swell sticks around 4ft to 7ft, but the wind is consistently onshore or cross-shore, especially from the NE and ENE. It’s messy, choppy, and mostly poor. The only flicker of hope is Saturday, August 8th morning – 6ft from the SE, with a cross-shore breeze and strong energy (762). The score is okay, but it’s a long way out and the wind is just cross-shore, not clean offshore. Keep an eye on it, but don’t hold your breath.
So, bottom line: Thursday morning is your best bet. Get out there early.
Rusty.
