The Lowdown

Alright folks, Rusty here. Let's take a look at what's on the menu for The Island.

We've got a solid run of surf kicking off Thursday the 13th of August. The Island is a consistent, exposed reef break that handles the SW swell well, but the early conditions are a bit messy. The water temp is sitting at 59°, which is pretty much average for this time of year, nothing to complain about there.

Thursday morning will see a decent 8ft SW swell rolling in with a very long 16-second period, carrying a ton of energy (2694). That's a powerful groundswell. The wind is light but cross-onshore, so expect some texture on the face. The afternoon stays similar, just a touch smaller. It's surfable, but not the pick of the week.

Now, Friday the 14th and Saturday the 15th are where we really see it come together. Friday morning has the swell holding at 7ft from the SW, still with that long 16-second period, but the wind swings to a light cross-offshore from the SE. This cleans the waves right up. The afternoon stays clean too. Then Saturday is the real standout. The swell drops a little to 6ft, but the wind goes full offshore from the ESE, blowing at 12 mph. The combined energy is still strong (1784). This is going to produce excellent, clean conditions for experienced surfers. This is your window. The size is right in that sweet spot for a reef, not too big, not too small.

Sunday the 16th still has clean waves as the swell eases to 5ft, and the offshore wind continues. It's a bit smaller, but the quality remains high.

We then hit a bit of a lull. The middle of next week sees the swell drop and the wind turn onshore, making for poor conditions. Monday the 17th is still worth a paddle with a clean 4ft swell, but by Tuesday and Wednesday the 18th and 19th, it's pretty grim with strong winds and a messy sea.

The surf tries to rebuild around Thursday the 20th, with a clean 5ft SW swell on the morning, but it gets blown out in the afternoon. Friday the 21st and Saturday the 22nd are a write-off with strong onshore winds and a big messy swell. The combined energy on Saturday afternoon spikes to 2646, but the wind is a strong cross-onshore at 25 mph. That setup is honestly more interesting for kite surfing than paddle surfing.

Looking further ahead, there's another potential window on Thursday the 27th of August. The swell picks up to 5ft from the SSW with a clean cross-offshore wind from the SSE. It's a promising sign for the end of the month, but it's far out, so keep an eye on it.

In short, the clear standout is Saturday the 15th. Get out there for the offshore winds and clean, powerful waves. Friday the 14th is almost as good. The rest of the week is a mixed bag of clean mornings and blown-out afternoons, with a rough patch in the middle.

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.
