The Lowdown
Alright, Rusty here, looking at the charts for The Island. First up, water temp is sitting pretty average for this time of year, nothing unusual to report.
The next couple of weeks are a real mixed bag, with plenty of onshore and cross-shore wind messing things up. We've got a couple of windows where it'll be worth paddling out, but mostly you'll be sitting this one out.
Thursday the 16th sees a solid, meaty 5ft to 5ft SW groundswell rolling in with a very long 15 to 17 second period. That's a lot of deep ocean energy (1540). The problem? The wind is cross-off in the morning, swinging cross later. It's clean enough, but the swell is just a bit raw and the forecast calls it marginal. Not the best start.
Friday the 17th drops off a touch to 4ft but still with that long period (16s). Cross-off winds again in the morning give us clean conditions, but the energy's dropping (897). It's alright, but nothing to write home about.
Saturday the 18th things get smaller (3ft) and the period drops (13s). With a moderate cross-shore wind, we've got a cross-chop. The weekend's looking flat and choppy, not worth it.
Sunday the 19th through to Tuesday the 22nd is a write-off. Swell is small or messy, winds are cross or cross-on, and the wave state is consistently described as having a cross-chop or being choppy. There's a bit of size on the Sunday afternoon (4ft) but the period is all over the place and the wind isn't cooperating. It's a stretch of poor to marginal conditions.
Now, listen up. Wednesday the 22nd morning brings a change. A light offshore breeze from the ESE at 6 mph cleans up that 3ft SW swell. The period is down to 12 seconds, so it's not as powerful (232), but it'll be glassy and clean. That's a morning for a fun little session on the longboard.
But the real standout is Thursday the 23rd. Look at that morning session. An almost glassy 3 mph NE wind, 4ft of SW swell with a 13-second period, and 470 in combined energy. The conditions are described as glassy. That is the pick of the entire period. Get out there early on Thursday the 23rd for the best, cleanest waves. The afternoon turns to onshore slop, so make the most of the morning.
Friday the 24th sees a big jump in swell, with 6ft in the morning (1206) and 7ft in the afternoon (2875). But the wind switches onshore, and the afternoon sees a moderate cross-shore with a cross-chop. That size with onshore wind is just messy.
Saturday the 25th and Sunday the 26th drop back down in size. Cross-off winds keep it clean, with 5ft and 5ft on Saturday. It's rideable, but the quality isn't there.
After that, from Monday the 27th right through to the end of the forecast on the 31st, it's all bad news. Fresh to strong breezes, onshore, cross-on, and rain. The wave states are described as lumpy, messy, or poor. We've got a 7ft swell on Thursday the 30th, but it's with 19 mph cross-on winds, making it a complete write-off for surfing. That setup would be more interesting for kite surfing than paddle surfing. There's a long gap of poor conditions from the 27th through the 31st.
So to sum it up: Thursday the 23rd morning is the one to circle. Glassy, clean, and a little swell. Get 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.
