The Lowdown
Alright, mate. Rusty here, giving it to you straight. The next sixteen days are a write-off for the most part. We’ve got a big gap of nothing to surf, and it’s going to feel like forever.
Looking at the first few days, the 15th and 16th have some chest-high waves around 5ft, but the wind is onshore and it’s messy. You’d be a fool to paddle out. Water temp is 85°F, which is normal for the season, but the surface is all over the shop.
From the 17th through the 25th, it’s flat and poor. The swell drops out completely, and there’s just nothing doing. This is a long stretch of quiet, so don’t get your hopes up. We’re talking over a week of nothing.
Now, if you’re desperate, the only flicker of life comes at the very end. Around the 26th and 27th, the wind finally goes light and clean, even offshore. Swell is tiny, only about 2 to 2ft, but the surface will be glassy. On the 27th, Right and Left Side should have a clean little wave with a gentle offshore breeze. It’s a small, weak swell, but it’s the best we’ll see in this whole window. The 28th and 29th keep that clean promise too, but the swell stays small. This spot is a slabby reef and it’s fickle, so don’t expect much. That’s a long way out, so treat it as a maybe. I’d check back later in the week, but for now, this is one to skip.
Rusty.

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.
