The Lowdown
Alright, Rusty here. Let's look at this stretch of water we've got coming. We're just focused on one spot, so the story is a simple one.
There's a big pulse of swell, but we've got to deal with some sketchy wind for a few days. The energy in the water will go from moderate to strong, so there's plenty of push.
The one to circle on your calendar is Friday, July 24th. The morning brings an offshore flow and a solid 7ft SW groundswell. That's some powerful, long-period energy, perfect for the reef. The water is running at 60°, which is a touch cooler than average, but nothing major. The energy reading is at 1735 (moderate to strong), and the wind is off it, so you can expect some really clean, lined-up waves. This one is for the experienced surfers only.
Then, the very next morning, Saturday, July 25th delivers again. We're talking a 7ft SW swell with light cross-off winds. This is the biggest swell of the whole stretch, with the energy hitting 2155 (strong), so you know it's got some serious power. The winds will keep it pristine. Again, this is advanced territory.
Before that, you've got a few days of chop. Wednesday the 15th has some decent 6ft SW groundswell, but it's messy. The afternoon glass-off is your best bet if you need a fix. Thursday the 16th has the swell but the wind is a problem. By Friday the 17th, the size drops, and it's not worth it.
After the big days, the surf fades. From Sunday the 26th, it’s small and clean, but just not enough push to be a proper recommendation.
So, if you're looking for the best, lock in the 24th and the 25th. That's where the good stuff is.
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.
