The Lowdown

G’day, Rusty here. Let’s break down what’s cookin’ for Shark Island (Cronulla). This is a reef break that loves a SSE swell, and over the next 16 days, we’ve got a couple of real gems if you’re willing to wait out the flat spells.

Overall Pattern

It’s a slow start with a few days of nothing much, then a solid pulse of energy mid-week, and a real interesting one in the second week. The water temp is about 63°F, which is roughly 1°F cooler than the long-term average for this time of year – nothing wild, just a typical winter chill.

The Forecast

We kick off on Saturday, August 1st with a morning that’s looking sweet. There’s a 5ft SSE swell rolling with a 9-second period, and the combined energy is moderate at 402. The wind is glassy from the W at 3 mph, so it’ll be clean and well-shaped. This is a solid option for the advanced crew, but keep in mind this spot can get a few heads out there sometimes. The afternoon gets messy with onshore wind.

Sunday, August 2nd is a bit of a letdown. The morning has a 5ft SSE swell, but the period jumps to 12 seconds, and the energy is strong at 743. The wind is cross-shore from the NNW at 9 mph, so it’s a bit choppy. The afternoon is a write-off with onshore NE 16 mph winds.

Monday, August 3rd through to Wednesday, August 5th are all flat or poor. The swell drops to under 3ft, and the energy is weak. Not worth paddling out.

Thursday, August 6th morning shows some life. A 5ft S swell with a 9-second period, combined energy of 337 (moderate), and a clean cross-offshore breeze from the WNW at 6 mph. This is a solid, clean session. The afternoon gets a bit bigger at 6ft but the wind goes cross-onshore, making it messy.

Friday, August 7th morning is another good one. A 5ft S swell, 9-second period, 407 combined energy, and a light cross-offshore breeze from the W at 3 mph. Glassy clean conditions. This is a real highlight for the early part of the week.

The Real Standout – Thursday, August 13th

Now, if you can wait, Thursday, August 13th morning is the pick of the whole forecast. The swell pushes up to 8ft from the S with a 9-second period, and the combined energy is a massive 1569 – that’s strong wave energy, no doubt. The wind is offshore from the SSW at 12 mph, and the conditions are described as excellent for experienced surfers. This is a big, powerful groundswell that will be firing down the reef. That said, at 8ft it’s for experts only – beginners stay well clear. The afternoon drops a bit but still has a 6ft S swell and clean conditions.

Late Forecast – Saturday, August 15th & Sunday, August 16th

Saturday, August 15th morning is a weird one. The swell is a tiny 3ft from the SSE, but the period is a very long 21 seconds, giving a combined energy of 1195 – that’s a lot of energy for such a small height. The wind is a light cross-shore, but that long period at a reef like Shark Island will likely result in a few clean, long lines, but it might be inconsistent. Promising but a bit uncertain.

Sunday, August 16th morning is the other big standout. A 4ft S swell with a 13-second period and a combined energy of 1088 – very strong. The wind is glassy from the SSE at 3 mph, making it super clean. The afternoon jumps to an 8ft SSE swell with a 13-second period and a massive 2152 combined energy, but the wind goes cross-onshore, so the morning is the clear winner here. That afternoon swell is too big for most, and onshore wind will make it a battle.

The Verdict

If you’re an expert, the clear winner is Thursday, August 13th morning – that 8ft S swell with offshore wind is a dream scenario. For a more manageable, clean session, Saturday, August 1st morning and Friday, August 7th morning are your best bets. The Sunday, August 16th morning is also a fantastic option with that long period groundswell and glassy conditions, but it’s a bit further out so keep an eye on it.

Stay safe out there.
