The Lowdown
Alright folks, Rusty here. Let’s get straight into it. Our only beacon in the water for this whole stretch is The Island, a solid advanced reef setup that’s exposed to the SW. This is a ride for the experienced crew, not for the learner.
The window kicks off on Wednesday the 29th of July with a serious pulse of energy. We’re looking at a 8ft SW groundswell with a very long 16-second period, pushing a massive 2854 of combined energy. It’s a proper beast. The wind is cross-off from the SSE though, so it’s not perfect, but it's clean enough for the crew who know what they’re doing. The water temp is sitting about average for the time of year, nothing weird there.
Thursday the 30th still has some size, 5ft from the SW and a 13-second period, and the energy is still stout at 802. Morning looks alright with a NE cross-off breeze keeping it clean. The afternoon gets a bit messy with a light cross-shore, not ideal.
Friday the 31st is dropping off fast. By the afternoon you’re looking at a small 3ft swell with a poor cross-onshore wind. Not worth paddling out for.
Saturday the 1st of August sees a new long-period 17-second swell, 4ft, but a fresh 22 mph N cross-breeze is going to turn it into a lumpy mess. The energy is moderate at 977, but the wind kills it. Sunday the 2nd is a bit bigger at 6ft to 7ft, but it’s still cross-shore and choppy. Monday the 3rd is the same story – clean enough but not special.
Now, here’s where it gets interesting. Wednesday the 5th of August is a standout. The morning is clean with a 3ft SW swell and a very long 18-second period, 924 energy. The afternoon is where the magic happens: a 4ft SW swell, 17-second period, combined energy of 1080, and the wind goes glassy from the SW. That’s the call for the experienced crew – clean, lined-up, powerful waves. This is the best on offer.
Thursday the 6th and Friday the 7th are a write-off, with onshore winds and chop. Saturday the 8th of August morning is a hidden gem – clean offshore wind from the ESE, 4ft SW swell, 16-second period, and 1243 energy. It’s a top-tier session for the experts.
After that, the wheels fall off. From Sunday the 9th through to Thursday the 13th, we get hammered by gale-force winds and big, blown-out swell. The 9th has an 8ft to 10ft SW swell with near gale onshore winds. The 10th is even worse with 10ft and a 37 mph cross-onshore. The rest of the week is all poor conditions with strong onshore winds. The Island is a reef, and with that much power and wind, it’s not a paddle-out spot; that’s more for the kite crew.
So, long story short: the first week has a few decent windows, especially Wednesday the 5th of August and Saturday the 8th of August for the experts. The second week is a total no-go. Stay patient.
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.
