The Lowdown
Listen up, crew. Rusty here, breaking down the Right and Left Side situation for the next couple of weeks. It's a rough patch, to be honest. This spot is an inconsistent reef break, so it doesn't take much to shut it down, and the wind and weather are really giving us the gears.
We start the forecast period on Monday, 24 August, but I wouldn't bother. There's a small 3ft NW groundswell, but it's a write-off thanks to a moderate cross-shore breeze and a risk of thunderstorms. The wave energy is a modest 256, and it's just not worth the effort. This theme carries right through the week. Tuesday the 25th sees a bit of swell from the ENE, but it's only 2ft at 13 seconds with a cross-onshore wind making things choppy. Wednesday the 26th offers a glimmer with a light cross-offshore breeze in the afternoon, cleaning up a tiny 2ft ENE swell, but it's still just "surfable but very ordinary." Thursday the 27th is similar, with light offshore winds and a small 2ft to 2ft swell, but it's barely a ripple.
The wind really picks up on Friday the 28th, with a fresh breeze ruining the 2ft ENE swell. Saturday the 29th is a mess. The morning is a write-off, but the afternoon is where it gets interesting for the wrong reasons. A 7ft W swell from a short 8-second period and a moderate cross-onshore wind creates a lumpy, choppy mess. The wave energy jumps to 729, but it's a powerful, ugly wave. This continues right into the start of September. The Sunday the 30th and Monday the 31st of August see a long-period W swell up to 6ft, but a fresh cross-onshore wind keeps it messy and lumpy (wave energy up to 783).
The first week of September doesn't offer much relief. The 1st sees a 6ft W swell with a moderate cross-shore chop, and the 2nd is marginal at best. There's a brief window of clean conditions on the 3rd, but with only a 2ft WNW swell, it's not really surfable. After that, the swell completely dies, with no wave height recorded on the 5th of September. Then, a new strong W swell shows up for the 6th and 7th, but it's over 7ft and hammered by a strong cross-onshore wind. The 7th has a 8ft W swell at a short 7-second period, with wave energy at 858. This is heavy, raw, and messy. It's only for the most experienced, and even then, it's a battle.
Honestly, the best this place has to offer in the whole 16 days is that Thursday, 27 August. A tiny 2ft to 2ft ENE swell, but with light offshore winds in the morning and afternoon. It's a micro-session, but the conditions are clean. If you're desperate for a paddle, that's your window. That Saturday the 29th and Monday the 7th of September have some power, but the wind is just all wrong. The wave energy peaks at 1041 on Tuesday the 8th of September, but with a 7ft W swell and a 25 mph cross-onshore wind, it's a washing machine, better suited for a kite than a surfboard.
There's a long gap of no real surf from the 3rd through the 5th of September. The forecast can change, so keep an eye on it, but for now, it's a lean run.

Information about the Right and Left Side Surf forecast
The above surf forecast table for Right and Left Side provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Right and Left Side can be found by selecting the local surf guide option on the grey menu. Our Right and Left Side 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 (Right and Left Side) 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 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.
