The Lowdown
Alright folks, Rusty here. Looks like we’ve got a solid 16-day window of surf ahead, but it’s not all blue skies and barrels. The Island’s the only spot on the cards, a reef break that’s strictly for the advanced crew. No messing around here.
The Island kicks off on Wednesday morning, July 15th, with a solid 6ft SW groundswell. The period is a chunky 15 seconds, and that’s pushing a ton of energy – we’re talking a combined energy reading of 1345. There’s a bit of a cross-off breeze, but it’s manageable. Honestly, the real standout start is Wednesday afternoon. The wind goes glassy, dead calm, and the swell is still a clean 5ft from the SW. That is the best it’s going to get for the first few days. Get out there if you can.
Thursday keeps the size around 5ft, but the wind starts to get messy. Mornings are cross-off, but afternoons turn into a cross-shore mess. The period is still long, but the energy is dropping. Friday and Saturday are a real letdown. The swell fades quickly to under 3ft by Saturday, and the wind is all over the place. Saturday afternoon is a write-off with poor conditions and weak energy. By Sunday, it’s a full-on slump with a fresh cross-shore breeze and a tiny 2ft swell. The next few days are a write-off for any decent surf.
Now, here’s where it gets interesting again. The forecast shows a pulse of new swell arriving on Thursday, July 23rd. It’s a 7ft SW groundswell, and the combined energy is a massive 1635. The wind is a clean cross-off, so it’s going to be lined up. This is a big wave, remember, over 8ft is for experts only. The swell direction is a perfect match for the optimum SW direction. This is the standout for the advanced crew.
The following morning, Friday, July 24th, is an absolute gem. The swell is still a solid 7ft from the SW, with a light NE breeze making for clean conditions. The energy is still pumping at 1945. This is the best session of the whole outlook. Don’t miss it.
The weekend of July 25th-26th sees the swell dropping back down to a more manageable 5ft or so, with glassy conditions on Saturday morning. It’s good, but not the standout. The following week is much smaller, with waist-high leftovers and clean offshore winds in the mornings. It’s a slow fade, but there’s always a chance of a sneaky clean morning session.
So, to sum it up: the first couple of days are fun, but the real deal is that Thursday-Friday window on the 23rd and 24th of July. That’s the big one. The long period SW groundswell loves this reef, so get ready for some proper, powerful waves.
Rusty, signing off.

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.
