Alright surfers, Rusty here. Let's get into what's cookin' over the next couple of weeks.
We've got a classic southwest groundswell train lined up for The Island, but Mother Nature is gonna make us work for the clean ones. The early part of the run is looking messy with strong winds, but there are a couple of windows of true magic if you're patient. The water temp is sitting right around 61°, which is just about normal for this time of year, so no surprises there.
Kicking off Wednesday the 8th, there's solid 6ft SW groundswell with a very long 17-second period, pumping a massive 2199 combined energy. The wind is a cross-offshore from the ENE, so the reef at The Island will be clean. This is your best bet early on, despite the score being a bit marginal on the face of it – the quality is there if the tide lines up for you.
Thursday the 9th sees the swell drop to 4ft but still with a long 15-second period. The morning looks clean with a NNE cross-off, making for a fun, manageable session. The afternoon gets a bit tricky as the wind swings NW and goes cross-onshore.
Friday the 10th through to Monday the 14th is a write-off. Strong winds, mostly onshore or cross-onshore, chopping up even the solid 6-7ft swell. Friday, Saturday, Sunday, Monday – all poor. Don't bother, the wind will just wreck it. You'd be better off surfing the couch.
Things start to clean up again on Tuesday the 15th. We get a cross-offshore breeze from the SE and a clean 7ft SW groundswell (2114 energy). This is a solid, powerful groundswell with a 15-second period, which loves a reef like The Island. Wednesday the 15th morning is a standout – clear skies, clean surf, and a proper amount of juice.
Thursday the 16th is smaller, 4ft, but still clean in the morning. A nice recovery day.
There's a gap of poor conditions from Friday the 17th through Monday the 20th. Strong winds, lumpy and messy. The swell stays strong at times (8ft on the 20th) but the wind is brutal. This is more of a kite-surfing setup than a paddle session.
Now, looking into the second week, we get the real prize. Tuesday the 21st is a beauty. The morning starts with a cross-off SE wind and a solid 8ft SW groundswell (1839 energy). By the afternoon, the wind drops to a light SSE breeze, the conditions go clean, and the 8ft swell is perfect for experienced surfers. This is the highlight of the whole outlook.
Wednesday the 22nd follows up with another gem. A 6ft SSW groundswell in the morning with a clean cross-off wind, and then the afternoon goes absolutely flat calm – glassy conditions with a 5ft SW swell. That's the kind of session you tell your mates about. Expect some company – the Island can get crowded, especially when it's this good.
Thursday the 23rd is a chill wind-down, smaller 4-5ft swell with a clean cross-off in the morning before the cross-shore kicks in.
Take it easy out there, and don't sleep on that Tuesday the 21st window.
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.
