Table - best surf conditions forecast for The Island over the next 16 days.
Alright folks, Rusty here. Let’s take a look at what’s coming up for The Island. It's a reef break that's consistent and exposed to the swell, but don't get too excited just yet – we’ve got a long wait ahead.
The first ten days of the forecast are a write-off. The wind is a mess. From Saturday the 11th right through to Tuesday the 22nd, it’s mostly onshore or cross-onshore, gusting strong, and the surf is described as poor. The water temp is sitting at 60°, which is about 2° cooler than normal for this time of year – nothing wild, just a touch on the chilly side.
We finally get a window of hope starting Wednesday the 15th. The morning brings a clean, cross-offshore breeze from the ENE at 9 mph, with a 6ft SW groundswell (period 15 seconds). That’s a proper long-period swell, which is perfect for a reef setup like this. The combined energy is moderate at 1363. Then the afternoon gets even better: the wind goes completely glassy, calm at 0 mph, with a 5ft SW swell. That’s the standout session of the entire forecast. The water will be clean, the waves will have shape and power – this is for experienced surfers only, as the swell is solid and the reef is demanding.
Thursday the 16th and Friday the 17th are still worth a look, but they’re not as special. The swell drops to 4ft - 4ft with a clean cross-offshore wind, but the energy is low (642-922). It’s a marginal call, but you’ll find a few fun ones if you’re patient.
The following weekend (Saturday 18th) fades out with lumpy cross-shore wind and small surf. Then on Sunday the 19th, the swell tries to pump back up to 7ft-8ft with a 18-second period, but the wind is howling onshore again. Kite surfers might get a kick out of it, but for a paddle surfer, it’s a mess.
The last real chance comes on Monday the 20th. The swell is still solid at 7ft with a 16-second period, and the wind is a gentle cross-shore from the SSW at 9 mph. The energy is strong (2185), but the surf is described as marginal. It’s a gamble, but if you’re desperate, it’s the next best thing after Wednesday.
So, the clear winner is Wednesday the 15th, especially the afternoon glass-off. That’s your best bet. Everything else is a waiting game or a scratchy session.
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.
