The Lowdown
Hey, Rusty here. Look, I’ve stared at this forecast for “Right and Left Side” and I gotta be straight with you – there’s nothing worth paddling out for in the whole 16‑day window, right through to August 3rd. This reef is inconsistent at the best of times, and this stretch is a total blank. The swell never matches the optimum N direction, and even when a little pulse tries to show up, the conditions just aren’t there.
We start off Sunday July 19th with a tiny 1.6ft easterly swell at 9 seconds – energy is weak (41). The wind is a light cross‑shore, but the surf is poor. The next few days are the same story: 1.3–1.6ft, mostly from the ENE, period around 9 seconds, energy in the 20–40 range. Monday July 20th morning has a gentle offshore, but it’s still too small and weak. That pattern holds through Wednesday July 23rd, even with a fresh offshore breeze on Thursday, but the swell is only 1.3ft – no push.
Friday July 24th the swell drops to 1.0ft, energy down to 15. Saturday July 25th the morning has a moderate offshore, but the swell is 1.0ft and then disappears altogether in the afternoon – zero energy. Sunday July 26th morning is glassy with 1.0ft, but again nothing. Then Sunday afternoon a pulse arrives: 2.0ft from the west, 11 seconds, energy 115 – moderate. Still poor surf conditions, though. That’s the first hint of something, but it’s not enough.
Monday July 27th sees a 3.3ft west swell at 12 seconds, energy 317 – moderate. Conditions are clean with a cross‑off breeze, but the wave quality is marginal at best. The optimum direction is still off, and the spot is inconsistent. Tuesday July 28th morning has 3.0ft from the WNW, 11 seconds, energy 198 – still clean, but again only marginal. By afternoon the wind turns cross‑shore and choppy, ruining it.
The rest of the forecast is a mess. From Wednesday July 29th through to August 3rd, the swell builds to 4.3ft from the NW with long periods up to 15 seconds, energy climbing into the 900s – strong. But the wind is cross‑onshore

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.
