The Lowdown
Alright folks, Rusty here. We’ve got a 16-day outlook for The Island, a solid reef break that’s exposed to the SW. The water temp is sitting at 59°, which is about 1° cooler than what’s typical for this time of year, so nothing too wild, just a touch on the fresh side.
The story here is a bit of a slow burn. The first few days are a write-off—Sunday the 2nd is a complete mess with 25 km/h cross-onshore winds blowing out a 5ft to 6ft SW swell. The wave energy is moderate to strong (1068-1366), but it’s all for nothing. Monday and Tuesday the 3rd and 4th are only marginally better; the swell drops to around 4ft and the wind is still messy, so you’re not missing much.
Things start to look up on Thursday the 6th. That morning we’ve got a clean 4ft SW groundswell (16-second period), with light offshore easterly winds. The combined energy is moderate (785), but the conditions are looking clean. This is the first real window for a paddle, but the swell is pretty small.
The real standout window comes much later, on Thursday the 13th and Friday the 14th. Thursday the 13th morning sees a 8ft SW swell with a 15-second period, and while the wind is light cross-onshore, it’s manageable. The real gem is Friday the 14th morning. We’ve got a 6ft SW groundswell (17-second period), light offshore winds from the SE, and the report calls for excellent conditions for experienced surfers. The wave energy is strong (1943), and that long period will make for some beautifully shaped, powerful lines peeling down the reef. This is your best bet—clean, solid, and with that long period energy. Just keep in mind, the crowds here can be an issue sometimes, so get in early.
The rest of the 16-day window is a bit of a gamble. There’s plenty of swell, but the wind is almost always onshore or cross, and for a lot of those days the swell is over 8ft, pushing it into expert-only territory with messy conditions. Honestly, from the 7th through to the 12th, it’s a blown-out, choppy mess with strong winds and huge swell. The 9th and 10th have a 10ft swell with near gale-force winds. That’s not a surf day, it’s a survival mission.
To sum it up: the first week is a wash. Pencil in Thursday the 6th for a small, clean session, but your one true standout is Friday the 14th. That’s the day to clear your schedule for The Island.
Stay frothy,
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.
