The Lowdown
Alright, Rusty here again. Let’s break down The Island in feet and miles per hour.
The water is about 59°F, which is pretty normal for this time of year.
The main story is a slow build of SW groundswell, but the wind is going to make or break it. The best session looks like Thursday, August 6th. That morning, you’ll have a clean 5ft of SW swell with a 16-second period, and the wind is offshore from the east at 9 mph. The combined energy is strong at 1133, so there’s plenty of power. This is one for the experienced crew—it’s not a beginner wave. The afternoon stays clean with 5ft.
Thursday, July 30th, the morning is also a solid option. Clean 5ft SW swell, 13-second period, and a cross-off breeze from the ENE at 9 mph. Energy is moderate at 732. The Island can get crowded sometimes, so be ready for company.
From Friday, July 31st, through Sunday, August 2nd, the wind gets messy. You’ll see 3ft to 5ft, but it’s cross-shore or onshore and choppy. Not worth the fight.
Monday, August 3rd, through Wednesday, August 5th, the swell holds between 4ft and 6ft, but the wind is inconsistent. Tuesday morning, August 4th, has a clean cross-off breeze, but it’s a minor window.
Then the big stuff hits. From Friday, August 7th, the swell jumps. By Saturday, August 8th afternoon, you’re looking at 8ft from the WSW with onshore wind—expert only, and poor quality. Sunday, August 9th, brings 8ft to 10ft with near-gale onshore winds. That whole stretch from the 7th through the 11th is big, messy, and dangerous. More of a kite session than a paddle.
Wednesday, August 12th, has a 8ft SW swell with a light cross-on breeze, but it’s a long way out and the confidence is low.
Your best bet is Thursday, August 6th. Clean, lined up, and plenty of power. Don’t sleep on it.
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.
