The Island Surf Forecast and Surf Report

Right, let’s have a look at what we’ve got for The Island. This is a reef break, and it’s the only game in town for the next couple of weeks. We’re in for a bit of a mixed bag, with a standout day on the 6th and another promising window around the 16th and 18th.

The forecast starts on Friday, 4th September, but honestly, it’s not worth getting excited about. We’ve got a solid 7 ft SW groundswell with a period of 16 seconds, so there’s plenty of energy (2293), but the wind is a messy cross-shore at 19 mph. The water is sitting at 60°, which is pretty much what you’d expect for this time of year. Friday afternoon and Saturday are a write-off with strong cross-onshore winds and similar messy conditions. Saturday has 8 ft swell, but the wind is just too ugly.

Now, Sunday the 6th is our first real standout. The morning is looking magic. We have a clean 7 ft SW groundswell, a period of 14 seconds, and the wind is a glassy offshore easterly at just 3 mph. The combined energy is strong at 2144. This is a proper reef-breaking wave, and with that light offshore, the conditions will be damn near perfect for experienced surfers. This is the one to circle. The afternoon drops to a cleaner 6 ft, but the wind goes cross-off, still a good session, but the morning is the call.

Monday the 7th is smaller, around 3 ft to 4 ft, with some clean windows on offer, but it won’t have the punch of Sunday. Tuesday the 8th sees a new pulse of long-period SW groundswell, 6 ft at 17 seconds, with a gentle offshore breeze. The energy is solid (1801). This will be a nice, clean reef wave, but that long period can make it a bit straight at times – it’ll be peeling nicely at The Island.

Wednesday the 9th is a bit of a tease. We have a big, long-period swell (8 ft to 8 ft at 18-20 seconds, with a massive energy of 4189-4353), but the wind is a strong cross-off at 25 mph. It’s clean, but that strong wind will make it a challenging paddle and the wave might get a bit bumpy. Not the best for a casual session.

The following week thins out a bit. The 10th and 11th offer some clean, smaller waves (4 ft to 6 ft), but nothing that screams “must-go.” From the 12th through the 14th, the swell drops right off, and the wind turns onshore or cross-shore, leaving us with poor, lumpy conditions. It's a real flat spell in the middle.

We do get one more big pulse on the 15th of September. The afternoon brings a 10 ft SW swell at 14 seconds, with a strong energy of 3336, and a cross-off wind. That’s big. For anyone not on a gun or a step-up, it’ll be a handful.

The next true standout is the 16th. The afternoon is a gem: 8 ft SW groundswell, 14 seconds, and the wind is glassy, completely calm. That’s a rare treat. It’ll be a clean, heavy reef wave, definitely one for the experienced crew only.

Then, on the 18th of September, we have another banger. The afternoon session is top-tier: 8 ft SW groundswell, a very long 18-second period, a moderate offshore wind, and a combined energy of 3176. This is a potent, clean groundswell. The morning is also big at 8 ft, but with a strong offshore wind that’ll be hard to get into. The afternoon is the real sweet spot.

To sum it up: you have two must-surf days: the morning of Sunday the 6th, and the afternoons of the 16th and the 18th. The 16th and 18th are the long-range calls, so keep an eye on them, but the 6th is locked in. There's a flat spell from the 12th to the 14th, so don't bother then. For the rest, it’s patchy. The Island is a consistent, exposed break, so it’ll always have something, but the wind is the key. Good luck out there.
