The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for The Island.
The swell window is open for this spot, and we’ve got a solid run of groundswell from the southwest. The water temp is sittin’ at 59°, which is pretty much normal for this time of year—nothin’ wild there.
The standout window starts Thursday, July 30th. Thursday mornin’ is where it’s at. You’ve got a 5ft SW groundswell with a 13-second period, clean as a whistle thanks to a light offshore breeze from the ENE. The combined energy is moderate (732). This is a proper advanced reef break, so it’s not for the groms. Conditions are clean and the early session is the one to chase.
By Thursday afternoon the wind swings cross-shore and the quality drops a notch—still surfable, but not the peak. Friday the 31st sees the swell drop to 3ft, still clean in the mornin’ with a NE breeze, but the energy is weaker (416). It’s a smaller day, better for a longboard or a cruise.
Saturday, August 1st is a write-off. The swell jumps to 4ft with a long 17-second period, but a strong north wind at 19 mph churns up a lumpy cross-chop. Energy is high (1000) but it’s messy. Not worth paddlin’ out.
Sunday the 2nd is even worse—strong onshore winds, rain, and 6ft of lumpy swell. That’s a hard pass.
Things start to clean up again Monday, August 3rd mornin’. The swell holds at 6ft from the SW, 14-second period, with a gentle cross-shore wind. The energy is strong (1386) but the conditions are only marginal. It’s more of a grinder than a glider.
The next true highlight comes on Thursday, August 6th. Mornin’ shows 5ft SW groundswell from a 16-second period, clean with a light offshore breeze from the NE. Energy is strong (1259). By afternoon, the wind goes glassy—ESE at just 3 mph—and the swell bumps up to 6ft with a 15-second period, energy hittin’ 1637. That’s excellent for the experienced crew. This is your best session if you’re willin’ to wait.
After that, Friday the 7th is still clean with offshore winds, but the swell is droppin’ and the wind gets a bit stiffer. It’s surfable but not the standout.
Then we hit a long rough patch. From Saturday, August 8th all the way to the end of the outlook, the wind is mostly onshore or strong cross-shore, with big lumps of swell but terrible conditions. The energy on the 9th and 10th is huge (over 2000), but it’s all windblown and messy. That stretch is for the kites, not the paddle crew. There’s nothin’ recommendable there.
So, bottom line: the best windows are Thursday, July 30th mornin’ and Thursday, August 6th afternoon. Everything else is either small, wind-affected, or just plain ugly.
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.
