The Lowdown
G'day, I'm Rusty. Let's have a look at what's on offer for Shipwrecks over the next couple of weeks.
The outlook kicks off with a solid run of swell from the 26th of August. We've got a consistent SSW groundswell building through the period, with a long period of 14 seconds bringing plenty of energy. The water temperature is about average for the time of year, so no surprises there.
Wednesday, 26th August starts us off with a clean 4ft to 5ft SSW swell. The wind is a moderate offshore from the SE, making for some tidy, lined-up waves. Combined energy is sitting at 670, which is moderate, and the sets will have a bit of push. A good day to get the arms working.
Thursday, 27th August the swell dips a little to 3ft in the morning, but the afternoon is where it's at. The period jumps to a very long 20 seconds, and the combined energy rockets up to 1365. The wind goes light cross-offshore, so the waves will be clean and glassy. This is a standout session for the more experienced crew – the long period will make it a bit fat and tricky on the reef, but the potential is there for some real gems.
Friday, 28th August is the pick of the first week. Swell bumps up to 7ft in the morning from the SSW, with a 16-second period. The combined energy is a strong 2663, and we've got a gentle offshore breeze. This is big, powerful, and clean – excellent surf for experienced surfers only. If you're an advanced paddler, this is your window.
Saturday, 29th August eases back to a still-juicy 6ft in the morning, dropping to 5ft in the afternoon. Winds are light and cross-offshore, keeping it clean. It's a very good day, but not as punchy as Friday.
Sunday, 30th August through Monday, 31st August sees a slight drop in size to 4ft to 5ft, but the period stretches back out to 18 seconds on Monday. The wind stays offshore, and the combined energy sits around 1100 to 1395. The longer period will make the waves a bit more drawn out, but again, that's a good thing for the reef if you know where to sit.
Tuesday, 1st September brings another pulse of 6ft SSW swell with a solid 17-second period, and a strong offshore breeze from the SE. The combined energy is 1588. This is another cracker for the experienced surfer.
Wednesday, 2nd September holds similar size at 5ft, but the wind becomes cross-offshore in the afternoon, making it a bit more variable. Still a very good day, just not as perfect as the morning.
From Thursday, 3rd September through Friday, 4th September, the size drops back to 4ft to 4ft, and the wind turns cross-offshore. The energy drops with it. It's still rideable, but more of a cruiser's day.
Saturday, 5th September is a nice return to form. The swell jumps back to 6ft with a 16-second period, combined energy of 1429, and a light breeze. It's a very good, clean day.
Sunday, 6th September stays similar at 6ft, but there's a chance of rain showers. The wind is still cross-offshore, so it's still surfable, just not as pretty.
Monday, 7th September fades a little to 5ft, and the wind stays cross-offshore. It's a good day, but nothing special.
Tuesday, 8th September has a morning of 4ft with a moderate offshore, but the afternoon is a real standout. The period jumps to a very long 19 seconds, combined energy of 1141, and a moderate offshore wind. The swell is a bit smaller at 3ft, but with that period and wind, it will be clean and lined up.
Wednesday, 9th September is a big call for the second week. Morning swell is 5ft with a 16-second period, and the combined energy is a strong 2013. The wind is offshore. This is excellent surf for experienced surfers. The afternoon gets bigger to 6ft, but the wind goes cross-offshore, making it a bit mushier.
Thursday, 10th September finishes the run with a solid 6ft SSW swell, a 17-second period, and a moderate offshore wind. The combined energy is a strong 2208. This is another one for the advanced crew.
The standout sessions are clearly Friday, 28th August and Wednesday, 9th September – both offering big, powerful, clean waves with offshore wind. The crowds are listed as "sometimes" at Shipwrecks, so you might score a few waves to yourself, but don't bet on it being empty.
Signing off, Rusty.
