The Lowdown
Alright, let’s talk about what’s coming. The first few days look like a total write-off with onshore winds and sloppy surf. But if you’re patient, the second week opens up with some real clean groundswell that’ll be worth the wait.
The only spot worth watching is The Island, a reef break that’s consistent and exposed to SW swell. It’s an advanced wave, so leave the longboard at home. Water temp is 61°, which is pretty normal for this time of year.
Wednesday 2nd and Thursday 3rd – forget it. Onshore winds, poor surf, total waste of a session. Friday 4th and Saturday 5th see swell at 7ft to 8ft from the SW, but the wind is howling onshore or cross-shore at 19 to 19 mph, making it lumpy and ugly. Some of those days are more suited for a kite than a paddle board.
Sunday 6th – finally a little relief. Morning is cleaner with a cross-off breeze, 6ft SW swell at 14 seconds. The combined energy is moderate (1307), but it’s still marginal. Afternoon drops to 5ft and gets choppy again.
Monday 7th – the swell bottoms out to 3ft, fresh offshore wind, but it’s just too small to get excited about.
Now, Tuesday 8th September – this is the first real standout. Morning brings 7ft of SW groundswell at a very long 17 seconds, with a gentle offshore breeze. The combined energy is strong (2381). Clean, powerful, and lined up for experienced surfers. Afternoon backs off a little but stays clean.
Wednesday 9th – morning is a write-off with strong winds, but the afternoon is a beast: 7ft SW swell at an extremely long 19 seconds under a strong offshore wind. The combined energy is massive (3683). The catch is that long period will make it hard to paddle into, and on a reef, it’ll be critical. Experts only.
Thursday 10th – another solid day with 7ft SW at 16 seconds, fresh offshore wind, clean. Good energy (2344). Still for the crew who can handle it.
Friday 11th through Saturday 12th – a drop in size and messy winds. Surf is poor, not worth paddling out.
Sunday 13th – size picks back up to 6ft SW at 16 seconds, clean in the morning with a cross-off breeze. Moderate energy (1461). Decent.
Monday 14th September – the best of the entire outlook. Glassy conditions, 8ft SW groundswell at 17 seconds, combined energy of 3010. This is a true standout. The reef will handle the long period swell beautifully, with clean, powerful lines. For experienced surfers only, but it’s going to be epic.
Tuesday 15th – still good, with glassy morning conditions and 5ft SW at 15 seconds. Energy (1174) is moderate. Clean, fun, and less intense.
Wednesday 16th and Thursday 17th – the swell fades to 5ft and 4ft, winds turn onshore or cross-shore, and the quality drops off. The run ends quietly.
So here’s the deal: the first week is mostly a bust. The real action is Tuesday 8th, with a standout on Monday 14th September – that’s the day to circle on the calendar. Glassy, solid, and clean.

Information about the The Island Surf forecast
The above surf forecast table for The Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Island can be found by selecting the local surf guide option on the grey menu. Our The Island surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (The Island) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for The Island may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
