G’day, Rusty here. Let’s talk about The Island. It’s a reef that loves a good SW groundswell, and we’ve got plenty of that coming, but the wind is going to be a real pain to start. Water temp is about 60°, just a little below average for this time of year – nothing too unusual.

Monday the 13th and Tuesday the 14th are a solid pulse of SW groundswell – 8ft at a long 16-second period, with moderate to strong energy (4795). Sounds unreal, but the wind is onshore and cross-onshore at 15 to 18 mph, turning it into a choppy, messy mess. No good.

Wednesday the 15th is the day. The swell drops slightly to 6ft, still that long 15-second SW groundswell, but the wind goes offshore from the ENE at a gentle 9 mph. Clean, lined-up surf. By the afternoon it goes glassy with a 5ft swell. This is the standout. The break is consistent and loves a SW direction. The combined energy is moderate (1382, then 1125). Crowds can pop up here, but on Wednesday it’s worth it.

Thursday the 16th is still okay. Morning has a clean 5ft SW swell with a cross-offshore breeze. Afternoon bumps to 5ft with a very long 17-second period, but the wind goes cross-shore, so it’s not as clean.

Friday the 17th fades to 4ft and the energy drops (905). Still clean in the morning, but small.

From Saturday the 18th through Tuesday the 22nd, it’s a flat, windy bust. Swell drops to 2ft to 3ft, wind howls at 18 to 22 mph cross-shore and cross-offshore. Energy plummets. Not worth looking at.

Wednesday the 23rd and Thursday the 24th see a spike back to 6ft to 7ft SW swell, but the wind is a brutal 25 mph cross-onshore. Blown out.

The second week is rough. Friday the 24th through Tuesday the 28th has size (6ft to 8ft), but the wind is onshore or strong cross-shore, hitting 34 mph on Saturday the 25th. The only slim chance is Monday the 27th morning – a 8ft SW swell with a cross-offshore breeze and clean conditions, but the wind is still a strong 22 mph, so it’ll be textured. For experts only. After that, rain, storms, and more onshore wind.

The one true standout is Wednesday the 15th of July. Everything else is blown out or too small.

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.
