G’day, Rusty here. We’ve got a decent run of surf lined up at The Island over the next couple of weeks, but it’s a bit of a mixed bag, so let’s break it down.
The action kicks off on Tuesday afternoon, July 7th, with a solid 4ft swell rolling in from the SW, and a long period of 16 seconds giving it some proper groundswell grunt. The combined energy is already pumping at 715 (moderate energy), but the real winner is that wind: a light 3 mph ESE cross-off shore keeping things glassy. This is clean, lined-up reef surf, and it’s a beautiful start for anyone who knows the break.
Wednesday, July 8th, is when the juice really turns up. Morning session sees the swell jump to 6ft from the SW, with a 17-second period – that’s long period groundswell, and the combined energy cranks up to 2199 (strong). Wind is offshore from the ENE at 6 mph, so the surface will be pure silk. The afternoon holds at 6ft, though the wind goes cross-off. This is excellent surf, but at 6ft on a reef, it’s one for experienced surfers only. Thursday the 9th is still worth a paddle: 4ft SW with a 15-second period, cross-off breeze from the NNE at 9 mph, and combined energy of 794 (moderate). Clean lines, but the swell starts to drop.
Now things get a bit ordinary. From Thursday afternoon through the weekend and into the following week, the wind swings onshore and kicks up. Thursday afternoon gets a cross-on breeze from the NW at 9 mph, and by Friday the 10th it’s onshore WNW at 9 mph, with the swell dropping to 4ft and combined energy falling to 714 (weak). Saturday and Sunday are a write-off: fresh to strong onshore winds from the WSW and SW at 22 mph, dumping all over a 6ft SW swell that would have otherwise been fun. The combined energy is actually solid (over 1200), but the wind junks it completely. Even the Monday the 13th is a no-go – 8ft SW swell, but onshore cross-on winds at 12 mph make for choppy, messy conditions, and at that size it’s only for experts anyway.
The tide starts to turn on Tuesday, July 14th. That morning delivers a glassy 6ft SW swell with a 16-second period, and a light 3 mph ESE offshore wind. Combined energy of 1700 (strong) – this is back to excellent, clean reef waves for experienced surfers. The afternoon holds the same size and period, with a light 6 mph S cross-off breeze. Wednesday the 15th offers a slightly smaller 5ft SW swell, still with that long period, and a clean cross-off NE breeze at 9 mph – combined energy drops to 968 (moderate), but it’s a good session for intermediates.
The second week, from July 16th onward, gets messy again. Thursday the 16th has a moderate 5ft SW swell with a 16-second period, but the wind is cross-shore from the N at 16 mph, creating a lumpy cross-chop. Combined energy of 1289 (moderate), but the surface quality is a letdown. Friday through Sunday (the 17th to 19th) are similar: fresh to moderate onshore or cross-shore winds between 16 and 19 mph, messing up swell that’s mostly in the 4ft to 5ft range. The standout in this stretch is Friday morning – a 5ft, 17-second period SW swell with 1426 combined energy (strong), but that fresh cross-shore wind from the N at 19 mph makes it a salvage job at best.
Monday, July 20th, sees the biggest swell of the whole run: a solid 10ft from the SW, with a 13-second period and combined energy of 2407 (very strong). But the wind is a near gale from the SW at 37 mph on the morning, and 31 mph in the afternoon – a total blowout. At that size and with those winds, don’t even think about paddling out; if you’re into kiting, the setup looks more interesting than paddle surfing. The rest of that week slowly winds down, with smaller swell but persistent onshore SW winds between 9 and 22 mph, keeping conditions poor right through Wednesday, July 22nd.
The best windows are absolutely Tuesday July 7th afternoon, Wednesday July 8th all day – that 6ft SW with offshore winds and 2199 combined energy is the top dog – and Tuesday July 14th morning. Crowds are listed as “sometimes” at The Island, so expect a few others with the same idea, but these windows are worth the effort. Remember, we’re talking a reef break here, so the long period (over 15 seconds) means the sets will be clean and powerful, with longer gaps between them – good for paddling out, but you need to know the line-up.
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.
