The Lowdown
Alright, this is Rusty. Let's get into it.
The first bit of the week is a bit of a write-off, but we’ve got something cooking toward the end of the month. We’re looking at The Island for this whole forecast, a solid reef break that’s exposed to the swell from the southwest. The water temp is sitting at 60°, which is pretty much spot on for this time of year, so don’t stress about a wetsuit just yet.
The surf kicks off on Friday, July 24th in the afternoon, but honestly, it’s a bit of a mess. We’ve got a 6ft swell from the southwest, but the cross-shore wind is chopping it up, making it marginal. The energy is there though, with a reading of 1211, so it’s not for lack of power. The next few days are straight up disappointing. Saturday and Sunday are mostly blown out, with strong onshore winds making a mess of things. There’s a brief moment on Sunday morning with clean conditions and a 4ft swell, but it’s small and short-lived. Monday is a total washout with strong, messy winds.
The patch of poor conditions stretches right through to the end of July. We’re looking at a solid 5-day gap of no good surf until we get to Wednesday, July 29th. That’s the real standout. Wednesday morning, the wind goes light and cross-offshore, and the swell jumps up to 7ft from the southwest with a long 15-second period. The energy is pumping at 2008, which is a solid reading. The comment says "excellent surf conditions for experienced surfers," and that’s because 7ft at a reef break like this is serious business. This is for the crew who know what they’re doing. The clean conditions and that long-period groundswell will make for some properly shaped waves, but the sets will be a bit more spaced out.
Thursday the 30th and Friday the 31st are still worth a look. Thursday morning is clean with a 5ft SW swell, and Friday is a real gem. Friday afternoon we get glassy conditions, a 3ft swell, but it’s packing a 19-second period—that’s a very long period groundswell. The energy is still high at 948. This is the kind of day where a longboard or a fish comes out, and the reef will be working its magic.
The first week of August is a mixed bag. Saturday the 1st is clean but small, and Sunday the 2nd brings a bigger pulse of 6ft with a 17-second period, giving a massive energy reading of 1995. The wind is cross-offshore, so it’s clean, but the tidal conditions might be a factor, so it’s a bit of a gamble. Monday and Tuesday the 3rd and 4th turn ugly again with strong winds, so we skip those.
The action picks up again on Wednesday, August 5th. The afternoon sees a 7ft swell from the WSW, but the wind is onshore, so it’s not as clean. The energy is there at 1792, but it’s a battle. Thursday, August 6th is a big one for the experts. The morning swell pumps to 8ft from the WSW with a 15-second period, and the energy is a massive 4159. The wind is cross-shore, so it’s got some chop, but the power is undeniable. The afternoon gets even bigger, hitting 8ft with a 20-second period and an energy reading of 6107. That is a serious, heavy groundswell, but the wind turns cross-onshore and choppy, so it’s only for the hardened local crew.
Friday the 7th is a complete no-go, with gale-force winds and big, messy swell. It’s a wrap after that.
The best of the best? Lock in Wednesday morning, July 29th for the biggest, cleanest swell of the first window. And if you want a clean, glassy, long-period day, Friday afternoon, July 31st is your ticket. The big stuff on August 6th is there for the experts, but the wind is a problem.
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.
