Table - best surf conditions forecast for The Island over the next 16 days.
Alright, Rusty here. Let’s talk about The Island. The next 16 days are a bit of a rollercoaster. We’ve got a decent SW groundswell coming through, but the wind is going to be a total pain for most of the first week. The water is sitting at 60°F, which is a couple of degrees colder than usual, so you’ll want a wetsuit.
We start Friday the 10th with a 5ft SW swell at 15 seconds, but it’s a cross-on wind, making it choppy. The energy is moderate (846). It’s a marginal call. Saturday the 11th gets bigger, 7ft to 8ft, but the wind is howling at 25 mph from the W and SW, making it a total mess. Not worth it. Sunday the 12th stays big with 7ft SW swell, but onshore winds are still ruining it. The energy is ramping up into the strong range (1252 to 1384), but it’s not clean. This pattern of big, onshore, messy swell continues right through Monday the 13th, with an 8ft SW swell showing a very long 16-second period and massive energy (3292), but it’s blown out.
The first real standout comes on Wednesday the 15th. The morning shows a 6ft SW swell at 16 seconds, with a clean cross-off breeze from the NE at 9 mph. The energy is strong (1612). This is the best the forecast looks for the first week. The afternoon is still good, dropping to 5ft with a light SE breeze. This is a proper reef break, so that long-period groundswell will be holding up well. It’s for experienced surfers, and it can get crowded, so keep that in mind.
After that, we drop off. Thursday the 16th and Friday the 17th see the swell fade to 4ft, and the wind goes cross-shore and lumpy. Not great. There’s a real gap of poor conditions from the 18th through the 20th, with small, messy, onshore slop. Saturday the 19th has a tiny 2ft swell with a bizarrely long 19-second period, but the wind is onshore and rubbish.
The run looks better again on Tuesday the 22nd. The morning shows a 4ft SW swell at 12 seconds, with glassy conditions. The wind is a glassy 3 mph from the SSE. This is your second standout. The energy is a quiet 459, but those glassy conditions on a reef will make it a fun, clean session.
The final few days into the 24th and 25th see a pulse of bigger swell, 7ft to 8ft, but the wind is back onshore or cross-on, making it a choppy, poor quality affair. There’s no clean way to enjoy that size.
So, to wrap up: The best windows are Wednesday the 15th and the morning of Tuesday the 22nd. The first week is largely a write-off due to wind, but the second week might offer a few more clean windows if the patterns shift. For now, keep your eyes on those two days.
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.
