Alright, Rusty here again, same story but in feet and miles. Let's do it.
We've got a solid run of surf kicking off Tuesday morning, July 7th, at The Island. It's a reef break, exposed to the southwest, and it handles a long-period groundswell like a champ.
Tuesday morning the 7th kicks it off clean. A light 10 km/h ENE breeze is blowing cross-offshore, and we've got a long-period SW groundswell rolling in at 4 ft with a 16-second period. That's proper groundswell, energy is solid (616) and the water temp feels about normal for the time of year. The report says "expect very good surf conditions" and the afternoon holds up, too, with a slight offshore breeze and a touch more size at 4 ft (715). Crowds are a possibility, so get in early.
Wednesday, July 8th, is where it gets serious. The swell jumps to 6 ft in the morning, with a 17-second period. The combined energy is pumping at 2199. That's strong, powerful stuff. The wind is still cross-off from the ENE, keeping it clean. This is "excellent surf conditions for experienced surfers" – and it's legit. The afternoon holds similar size at 6 ft (1634). This is the standout of the first week if you've got the experience.
Thursday the 9th still has some juice, with 4 ft and a 15-second period in the morning. The wind is cross-off, so it's still clean, but the energy is dropping (796). The afternoon gets a bit tricky with a cross-shore wind, so the morning is the call.
Things get ugly from Friday the 10th through to Sunday the 12th. Onshore winds and a choppy mess. Saturday has a 30 km/h cross-on wind, and Sunday is a full-on onshore blow with 7 ft of swell but terrible conditions. Don't bother.
Monday the 13th is another big day, but it's a tough one. The swell is up to 8 ft with a huge 19-second period, and the energy is a massive 4678. That's a serious groundswell, but the wind is cross-on from the SW, making it choppy. It's for the hardcore crew only.
The rest of that week is a mix of cleanup and messy conditions. But look ahead to Wednesday, July 15th. The wind swings offshore again from the ENE, just a light breeze. Swell is a solid 5 ft with a 15-second period (928). This is another real clean window. The morning will be glassy.
Beyond that, into the second week, we see more clean mornings but the swell gets smaller. Thursday the 16th and Monday the 20th both have clean morning windows with some SW groundswell, but it's around 4-5 ft. Nothing to write home about.
So, the absolute best of this outlook? Wednesday morning, July 8th. It's got the best combination of big, powerful swell (6 ft from the SW), a very long period (17s) that will wrap beautifully into this reef, and clean cross-offshore wind. It's an expert's session. Wednesday morning, July 15th is the best for the more moderate surfer – clean, offshore wind, with a solid 5 ft groundswell.
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.
