The Lowdown

Right then, grab a coffee and settle in, because the next couple of weeks are a bit of a mixed bag. We've got one solid reef break to focus on, so let's get into it.

The water is sitting at 59° right now, which is about what you'd expect for this time of year, nothing unusual there.

The first few days are a write-off, honestly. From Saturday the 8th right through to the end of the week, The Island is just getting hammered. We're talking strong cross-shore winds, lumpy chop, and at times a near gale blowing straight onshore. There's plenty of swell, but it's a total mess. The combined energy jumps around a lot, hitting over 3900 on the Sunday, but with the wind howling it's unsurfable. You'd be better off staying home.

There's a bit of a lull in the quality, but things start to show some promise around the 14th of August. The Friday morning (14th) has a 8ft SW groundswell with a very long 18 second period, and the wind is a light cross-onshore. The combined energy is a solid 3306, but the breeze is just light enough to keep a bit of order. The conditions are still described as marginal, so it's not firing on all cylinders.

Now, here's the standout. Saturday the 15th of August morning is the best we've got in this whole run. The wind swings around to a light SE, giving us a clean cross-offshore breeze. The Island is seeing a 7ft SW groundswell, with a period of 16 seconds, and the combined energy is a healthy 2059. The comments say "excellent surf conditions for experienced surfers," and I'd back that. It's a reef break, so it's an advanced wave, and at 7ft, it's solid. The long period means it'll have plenty of power, and the offshore wind will keep the faces clean. The crowd profile says "sometimes," so you might get a few others out, but it's worth the paddle. For a few sessions after that, the Sunday morning (16th) has clean 5ft surf with an offshore breeze, and Monday afternoon (17th) goes glassy with a 4ft SW swell—beautiful conditions, just smaller.

The real wildcard is Thursday the 20th of August morning. The forecast shows a massive 12ft SW groundswell, with a 17 second period, and the combined energy rockets up to 10923. That's a huge amount of energy. The wind is a light SE, keeping it clean. This is a big, powerful swell. For the experts, this could be a session of the year, but for anyone else, it's dangerous. That's a heavy wave on a reef. It's a long way off, so treat it as a promising possibility, but don't book the day off work just yet.

Overall, the pick of the run is a toss-up between the clean, solid Saturday morning on the 15th, and the potential monster on the 20th. If you're a competent surfer, the 15th is the safe bet for quality waves. The 20th is the lottery ticket.

Stay safe out there.

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.
