Alright folks, Rusty here. Let's have a look at what the charts are serving up for The Island. It's a reef break, exposed and set up for a good SW groundswell. Water temp is sitting at 60.8°, which is about normal for this time of year, so no surprises there.
The pattern is pretty clear: we've got a solid, long-period SW groundswell arriving, and it's going to stick around for a while. The energy is strong, hitting a massive 2438 on Friday the 3rd, and it's pulsing through the weekend. For the experienced crew, Saturday the 4th is your standout. The morning is looking magic with an offshore breeze from the E at 9 mph, grooming that 5.6 ft SW groundswell (14-second period) into clean, contestable lines. That's the pick of the first week. There's also a strong pulse on Sunday morning the 5th, with a 6.2 ft SW swell and a very long 17-second period, pushing the energy up to 2228. The wind is cross-offshore though, not quite as glassy as Saturday but still clean. Keep in mind that with a period that long, it's a proper groundswell – these waves have serious energy and will be a bit more lined-up and better shaped at a reef like The Island, but the gaps between sets will be longer.
Monday the 6th sees the swell start to back off, dropping to 3.9 ft and losing that real grunt. The waves will still be there but a lot weaker. The middle of the week (Tuesday 7th to Thursday 9th) is small, with clean conditions but nothing to get excited about. We get a bit of a second pulse from Wednesday the 8th, with a 6.6 ft SW swell and another 17-second period, pushing the wave energy back up to 2316, but the wind is cross-offshore from the NE. The conditions look clean, but that cross-off angle might pull the wave a bit.
Now, the outlook gets a bit gnarly for the second week. Saturday the 11th sees the swell pick up again, but the wind swings northerly, putting a cross-chop on it. Sunday the 12th is a write-off for surfing – a strong SW wind at 22 mph and a lumpy, cross-onshore mess with an 8.2 ft swell. It's going to be ugly.
The real standout of the whole 16-day period actually falls on Monday the 13th. The swell is a solid 9.8 ft from the SW, the combined energy is a whopping 5296, but the wind is a strong cross-shore from the SSW at 12 mph. That's going to make for powerful, challenging surf. This is strictly for the experts; it's too big and powerful for anyone without serious experience. For the rest of that week, the swell drops back down, and the winds remain tricky.
For the final weekend, the 17th and 18th, we get back to smaller, cleaner conditions with light offshore winds. It's a nice way to finish, but the real magic is in that first weekend and the big, raw power on Monday the 13th.
Best bet: Saturday morning, the 4th of July. Get on it.

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.
