The Lowdown
Alright, Rusty here. Let me tell you what this stretch of time is looking like for The Island. We've got a real mixed bag, boys. It starts off pretty rough but there's some proper gold hidden in the second week if we can wait it out.
Right now, there’s no surf worth paddling out for. The start is dead quiet. We’re looking at a few days of nothing until Wednesday the 29th when things get interesting. That morning the wind is swinging cross-offshore with a solid 8ft SW swell, period hanging around 16 seconds. That's proper groundswell energy, and the combined energy is massive at 2854. It's still a bit raw, but you can feel the power in the water. The water temp is sitting at 59°, which is just about 1° below normal for this time of year, so it's average, nothing shocking.
Thursday morning the 30th is the first real standout for me. The wind turns light and cross-off from the ENE at just 6 mph, making the waves glassy. Swell is a clean 5ft from the SW, period of 13 seconds, and the combined energy is a solid 802. The surf will be clean, fun, and all over the reef. Crowds can pop up here sometimes, but with the cleaner conditions, it’s worth jostling for a few.
Moving into Monday the 3rd of August, this is where I get a little emotional. The wind goes offshore from the E at 12 mph, and we’ve got 6ft of SW groundswell at 14 seconds. The combined energy is 1427. This is the best on offer in the first week. It’s excellent for experienced surfers, clean, with that offshore combing out every bump. This is a session you don't want to miss.
Then we have a quiet few days, but I’m holding out for the real prize later on. Tuesday morning the 11th of August is a beast. We’re looking at 10ft of SW swell, period 18 seconds, and the combined energy is a massive 5053. That’s a whole lot of ocean moving. The wind is moderate cross-shore, so it’ll be a bit lumpy, but for experts only. This is serious size.
And then, Wednesday the 12th of August. This is the absolute standout of the entire 16-day window. The wind turns light offshore from the ESE at just 6 mph, and we’ve got 8ft of powerful SW groundswell at 18 seconds. The combined energy is 4806. That’s a long-period groundswell right in the zone, and with offshore winds, it’s going to be clean and epic. For experienced surfers, this is the day. It’s a few weeks out, so it’s a little less certain, but the signs are incredible.
After that, things drop back down, but honestly, with these two heavy hitters in the second week, I’m buzzing. First week is a grind, but stay patient.
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.
