G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for The Island is a bit of a mixed bag, and you’re gonna have to be patient. The first week is mostly a write-off thanks to strong onshore winds and messy conditions, but there’s a couple of proper windows where this reef setup comes alive. The water temperature is sitting at 60°, which is a bit colder than normal for this time of year, so don’t forget a thick wetsuit.
The first real chance you’ve got is on Wednesday, July 15. The morning starts with an offshore breeze from the ENE at 9 mph, and the swell is a solid 6 ft from the SW, with a long period of 15 seconds. That’s classic groundswell – good energy, long sets, and the reef will handle it beautifully. The combined energy is strong (1699). The afternoon gets even better – glassy conditions from the ESE at 3 mph, with the swell dropping slightly to 6 ft but still packing a punch from the SW at 15 seconds (1224 combined energy). This is the standout session. The Island is an advanced reef break, consistent, and exposed to the SW. It can get crowded sometimes, but with clean conditions this good, you’ll be sharing the peak with a few others who know what’s up.
After that, the surf stays small and the wind turns messy again until the end of the week. There’s a gap of several days with no real recommendations – Thursday, July 16 and Friday, July 17 have clean conditions but only marginal, weak swell around 4 ft to 4 ft, not worth paddling out for.
Then, on Tuesday, July 21, we get another standout. The morning is glassy again with an ESE breeze at 3 mph, and the swell is a solid 8 ft from the SW at 13 seconds (2217 combined energy). That’s a powerful groundswell, and the offshore glass will make it smooth as silk. This is expert territory – 8 ft is pushing into big-wave range, and the reef will be throwing out some serious barrels. If you’re not on your game, sit this one out. The afternoon stays clean but drops to 7 ft, with a light onshore, still a good option.
The rest of the forecast is a mix of onshore winds and lumpy conditions, with the swell hanging around 5 ft to 7 ft but never lining up with good wind. The long-range stuff from July 23-24 has some energy but the wind is just too cross-on to make it work. All in all, circle the 15th and 21st – those are your days.
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.
