The Lowdown
Right and Left Side is a reef break that takes its swell from the north, but this 16-day stretch is a real dry spell. There’s a long stretch of days with nothing but tiny, weak walls, and it takes over a week before any proper juice shows up. Even then, the wind and period keep things from being epic.
The first real surf doesn’t roll in until Wednesday, 5 August, so you’ve got a gap from right now all the way through to the morning of the 5th with no decent waves. That’s a long blank run, and for this spot, it’s not totally out of the ordinary – forecasts can always change, but currently, it’s pretty grim.
On the morning of Wednesday, 5 August, things finally wake up. The wind is glassy, dead calm, so the surface will be like a mirror. There’s a 0.9m (3 feet) northeast swell running with a long 13-second period, which means real groundswell energy. The combined energy is moderate at 282, so it’s not huge, but for this reef, that long period and clean wind will produce some sweet, peeling lines. Crowds are listed as “sometimes,” so you might see a handful of other surfers, but it won’t be a fight for waves. This is the best it gets. Water temp is about average for the time of year.
By Thursday, 6 August, the swell fades. The morning has a glassy 0.6m (2 feet) northeast swell with a 12-second period, and the energy is weak at 114. It’s surfable, but honestly, it’s very ordinary – a longboard or a funboard kind of day. The afternoon stays glassy, but the energy drops to 84, and it’s barely worth paddling out.
Water temps are right around the seasonal average.

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.
