The Lowdown

Alright folks, Rusty here. Let's have a look at what The Island has in store for us over the next couple of weeks.

Straight up, this is a consistent spot that’s exposed to a solid SW groundswell, so there’s always something to keep an eye on. The water temp is sitting at 59°, which is bang on average for this time of year, so nothing freaky there.

The outlook gets going from Saturday the 22nd of August. It’s not a perfect start though. We’ve got a decent 6ft SW swell pushing in, with a very long 15 second period packing a heap of energy (1502), but the wind is a light cross-onshore. It’s surfable, but not the cleanest. Sunday morning the 23rd cleans right up with a crisp cross-offshore breeze from the NNE at 16 mph, and the swell holds at 6ft on a 17 second period. The energy is even stronger (1673), and with that offshore flow, it’ll be well-shaped. That’s your best early call.

Monday the 24th is a write-off. The swell drops to 3ft and the wind goes wild. Tuesday the 25th sees a jump in size – 7ft to 8ft – but the onshore wind turns it into a lumpy mess. Not worth it.

The next true standout window arrives on Thursday the 27th of August. The afternoon session is the one to aim for. You’ve got a solid 7ft SW swell pulsing with a very long 19 second period, and the energy is absolutely cooking (3505). The wind is a gentle cross-shore, so it’ll be a little lined up but still clean. This is proper, powerful, long-period groundswell, and it’s going to be lining up nicely on the reef. For the experienced crew, this is a serious session.

Friday the 28th keeps the size around 6ft to 6ft, but the wind is all over the shop. Saturday the 29th brings a beautiful change: morning glass-off conditions with a light 9 mph offshore breeze from the E. The swell is a more manageable 5ft, and it’s going to be clean as a whistle. Perfect for a long, fun session.

Sunday the 30th is a tale of two sessions. The morning is smaller at 3ft but glassy with an offshore wind, and that swell period stretches out to a massive 19 seconds. That’s very clean, but you’ll be waiting for the sets. The afternoon jumps to 7ft with the same long period – a big, clean swell for the experienced. That’s another standout.

The first week of September is a bit messy with onshore winds and lumpy conditions. A quick mention for Wednesday the 2nd of September morning: a little clean-up with an offshore wind on a 4ft SW swell. A small, clean option. Then, look ahead to Friday the 4th of September morning. This is the best call of the whole forecast. You get a 6ft SW swell, a 15 second period, and light cross-offshore winds from the SE. The energy is solid (1548) and the conditions are described as excellent for experienced surfers. Mark that one in the calendar.

After that, the weekend of the 5th and 6th of September fades out with onshore winds and dropping swell.

The standout windows are Thursday the 27th of August afternoon for a big, powerful session, and Friday the 4th of September morning for the best combination of size, period, and clean conditions. Lock them in.

Rusty.

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.
