The Lowdown

G’day, Rusty here. Look, I’ll be straight with ya – the next week and a half is a bit of a mixed bag for Shark Island, but we’ve got a proper gem hiding in there if you’re patient.

Right now, the swell is tiny and the winds are messy. We’re looking at a few days of small, ordinary surf from Wednesday 2nd September through to the start of the following week. Wednesday morning’s got a 2ft south swell, but with a cross-shore breeze and a weak 124 energy reading, it’s just not doing anything. The water is sitting at 63°, which is pretty much bang on average for this time of year. The afternoon cleans up a touch with a light cross-offshore wind, but it’s still only 2ft – barely a ripple.

Thursday and Friday are similar, with 2ft to 3ft south swells. Thursday morning’s got a light offshore wind, making it clean, but the energy is low (85). Friday’s morning session looks the best of this early stretch – 3ft south swell, light cross-offshore breeze, and the energy bumps up to 186. It’s surfable, but nothing to get excited about. The weekend is a write-off – Saturday’s hit with a fresh cross-shore breeze and a 2ft south swell, and Sunday’s got a lumpy cross-chop on a 4ft south swell.

Now, here’s where it gets interesting. Monday 7th September is still poor, but look ahead to Thursday 10th September. This is the standout. Thursday morning delivers a solid 13ft south swell, with a clean offshore breeze and a massive energy reading of 2565. That’s serious grunt. This is a reef break, so it’ll handle that size, but it’s definitely for experienced surfers only – well over the 8ft mark, so leave the beginners on the beach. The period is 9 seconds, which is a decent short-period groundswell, and it’s coming from the south, which is the optimum direction for this spot. The morning window is the pick, with that offshore wind keeping it clean. Thursday afternoon sees the swell drop to 12ft and a light cross-onshore wind creeps in, making it a bit lumpy, but still a solid day.

Friday 11th September is still a strong 6ft south swell in the morning, but the wind is cross-onshore, so it’s a bit bumpy. Energy is still high at 1037, but it’s not as clean. The afternoon gets wrecked by a 18 mph onshore breeze.

After that, the surf fades into the second week. Saturday 12th September has a 4ft south swell with a cross-shore breeze, and Sunday 13th is a messy 4ft east swell with poor wind. Monday 14th September morning is interesting – a 6ft east-northeast swell with glassy conditions, energy of 521, and the forecast says “expect good surf conditions.” That’s a real dark horse, especially if you like it clean and glassy. But after that, it’s back to small, poor surf right through to the end of the 16-day window.

Bottom line: if you want the best, be at Shark Island on Thursday 10th September morning. That 13ft south swell with offshore wind is the real deal. Monday 14th morning is a solid backup if you miss the main event. The rest is mostly a waiting game.

Rusty.
