The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for The Island over the next couple of weeks.
We’ve got a slow start, with nothing worth paddling out for on Wednesday or Thursday, July 22nd and 23rd. The wind is a mess – cross-onshore and strong, making the surf poor. It’s a bit of a waiting game, but hang tight, because the real action kicks off on Friday morning, July 24th.
That’s your standout window. Friday morning brings a glassy dawn with an offshore breeze, and the swell is a solid 6 ft from the SW with a very long 15-second period. The combined energy is pumping at 1443 (moderate to strong). This is a classic set-up for the reef. The water temp is sitting at 61°F, which is about average for this time of year, so nothing unusual there. Friday morning is the one to circle – it’s going to be clean, powerful, and a proper treat for the experienced surfer. The afternoon still has some fun 6 ft swell, but the wind swings cross-shore, taking the edge off.
Saturday morning, July 25th, drops off quickly with onshore wind and a smaller 4 ft swell. We’ll see a few lully days after that. Sunday morning, July 26th, offers a window of clean cross-off wind and a 4 ft swell, but it's small. The surf stays low and often messy through the early part of the following week.
Look further ahead to Wednesday, July 29th, and things start to look promising again. The afternoon session is a beauty: 5 ft SW swell, clean conditions with a light cross-off breeze from the NE, and a combined energy of 1076. It’s excellent for experienced surfers. Thursday, July 30th, keeps the clean theme going with a moderate 4 ft swell.
The first week of August brings more potential. Saturday, August 1st, shows a 5 ft SW groundswell with a very long 16-second period, but the wind is a bit messy. The real long-range highlight is Wednesday, August 5th: a clean morning with a light offshore breeze, 4 ft of SW swell, and a lovely 17-second period. The energy is solid at 946. That’s a promising one, though it’s more than a week away, so keep an eye on the forecasts.
Overall, the best bet is Friday morning, July 24th, with Wednesday afternoon, July 29th, as a close second. The Island can be a fickle spot, but when it lines up, it’s worth the wait.
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.
