Alright, let's get into what's on the table for the next couple of weeks. It's all about The Island, a reef setup that’s exposed to the SW. Water temp is sitting at 16°, which is pretty much bang on average for this time of year, nothing unusual there.

We kick things off Sunday, July 5th with a nice clean pulse. The swell is 7 ft from the SW, and that period is a solid 17 seconds – proper groundswell, lots of energy behind it (combined energy of 2400). The wind is light offshore from the ENE, only 20 km/h, making for some seriously clean conditions. This is prime for experienced surfers, no doubt. The long period means it'll be a bit walled at some spots, but on a reef like The Island, it should set up nicely. Crowds are on the radar here sometimes, so expect company.

Sunday afternoon keeps the quality high, easing a touch to 6 ft SW, with the period still long at 16 seconds, and the wind goes light east at 10 km/h, still offshore. Clean as it gets. The energy is still pumping (1648).

Monday the 6th sees the swell drop to 4 ft in the morning, period at 14 seconds, but the wind goes cross-offshore from the ENE at 15 km/h. Still clean, but the energy drops off to 618. It's a fun, smaller day. Monday afternoon gets a bit weaker, 3 ft and only a 1 out of 10 vibe, so don't expect much.

Tuesday the 7th picks up again, 4 ft to 4 ft, good offshore wind in the morning from ENE and clean conditions through the day. The period stays at 16 seconds, so the shape should be there, but the energy sits around 616-715.

Wednesday the 8th brings a bigger pulse back, with 6 ft in the morning and 6 ft in the afternoon, both from SW, and the period jumps to 17 and 16 seconds. The wind is cross-offshore from NE at 15-20 km/h, so the surface stays clean. The energy is solid – morning clocking 2192, afternoon 1497. This is a quality day, but the rating is marginal due to tide or conditions.

Thursday the 9th sees the swell back down to 4 ft with a 15-second period, but the wind is cross-shore from NNE, so it's not as clean. The energy is moderate at 610.

Friday the 10th is mixed, 5 ft from SW, period 15 seconds, but the wind goes cross-shore from the north, then cross-onshore by the afternoon, making it choppy. Not the best.

The weekend of the 11th and 12th is a write-off. Saturday the 11th has heavy wind – 25 mph from the north, then 28 mph from the WSW with rain. The swell is small but messy. Sunday the 12th brings rain and onshore gales near 28-34 mph, with waves building to 7 ft to 8 ft, but it's all blown out. The combined energy is 1131 to 2079, meaning there's a lot of power, but the wind kills it. This would be more of a kite session than paddle.

Monday the 13th is still big and ugly: 10 ft from SW in the morning with 25 mph cross-onshore wind from SSW. The energy is huge at 3330, but the conditions are messy. Tuesday the 14th is a bit better, swell hanging around 7 ft to 8 ft, period 16-19 seconds, and the wind is cross-shore from the south at 16 mph. The energy is massive (2794-3226), but the cross-shore wind keeps it from being perfect.

Now, Wednesday the 15th – this is a true standout. The morning brings 6 ft from SW with a 16-second period, light cross-offshore wind from SSE at only 9 mph, and the combined energy is 1739. Clean, powerful, and the wind is just right for the shape. This is excellent for experienced surfers.

Thursday the 16th is still solid but the wind goes onshore in the afternoon, so mornings are better if you can snag them.

The following weekend (18th and 19th) has some potential. Saturday the 18th has 7 ft to 7 ft from SW with 16-17 second periods, but the wind is cross to cross-onshore, so it’s marginal. Sunday the 19th morning is a gem: 7 ft from SW, 14-second period, and clean with a cross-offshore wind from NE at 9 mph. Energy is 1974. That's another standout window.

Monday the 20th sees the swell holding at 8 ft, but the wind goes onshore in the afternoon, so the morning is your window if you're keen.

Overall, the best on offer is Sunday the 5th and Wednesday the 15th, with Sunday the 19th morning as a close runner-up. The first week has more consistent quality, while the second week has bigger energy but more wind issues.

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.
