The Lowdown
Right, look… I've been staring at the charts for the next couple of weeks and, blimey, things are looking pretty rough for this spot. We're talking about Right and Left Side, a reef break that’s rated for advanced surfers and is notoriously inconsistent around here. Normally, it's an exposed spot that likes a northerly swell, but right now it’s getting hammered.
The core issue is the wind. For the entire 16-day window, it's pretty much locked in from the south-west to west, blowing anywhere from a strong cross-shore to a nasty cross-onshore. It's not going to clean up; it's just going to be choppy, lumpy, and messy. The wave energy is there – we’ve got a massive pulse kicking off around the 27th of August with the combined swell energy hitting 1196 (that's moderate to strong), and it just builds from there. By the 1st of September, the energy is absolutely thumping at 3516, but the wind is still a fresh cross-onshore, making it total, messy mayhem.
Right now, this is looking far more interesting for a kite surfer having a blast in the chop than for a paddle surfer.
There is a tiny, tiny flicker on the 3rd of September. The swell drops right off to 2ft, but the wind goes cross-off and it looks clean. The problem is the energy is weak at 112, and the period is only 10 seconds, so you’d be scratching around for a dribbler. Not worth getting wet for.
The only semi-glimmer of hope is on the 4th of September morning. We get a clean, cross-off wind, a solid 10ft groundswell from the west with a solid 12-second period, and the energy is raging at 2656. It’s rated as ‘marginal’ which is the best score on the board. The problem is the swell direction is West, and this break wants North. It’s a reef, so that long period will wrap a bit, but the main issue is that by the afternoon the wind swings back onshore. For the advanced crew only, there might be a few heavy, clean barrels in the morning before it all blows out. But honestly, it's a long shot.
Overall, there’s nothing I can truly recommend for the paddle surfer here. It's a grim outlook. This stretch of coast is used to going flat or blown out, so a blank run like this isn't unusual. We just have to hope the patterns shift.

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 Right and Left Side 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.
