The Lowdown
Alright, Rusty here. Let's chew the fat on this stretch.
Right off the bat, I gotta be straight with you. We're looking at a pretty grim run for the next week or so. Right and Left Side is just not firing. For the first few days, from Tuesday the 28th right through to Friday the 31st, we're dealing with ankle-snappers and knee-high slop. The swell is tiny, barely 1 foot to 2 feet, and the period is short, so there's no push to it. The wind is mostly light and cross-off or glassy in the mornings, which would be a dream if there was any wave to ride. There's just no energy. The combined energy is barely registering, stuck in the teens and twenties. It's a total write-off.
We do have a little bump coming in on Saturday the 1st of August. The swell jumps to a more interesting 4 feet from the East, with a solid 14-second period. That's a proper groundswell, and the combined energy is up to 577. That's more like it. The problem? The wind is a cross-onshore Westerly at 9 mph, and by the afternoon it goes fully onshore. It's going to be choppy and bumpy. The morning *might* offer a few rideable waves if you're desperate, but it's not going to be pretty.
Now, after that brief tease, we hit a wall. From Sunday the 2nd of August all the way through to the end of the forecast on the 12th, it's a relentless onslaught of onshore wind. We're talking moderate to fresh breezes, and then strong breezes from the WSW and West, all hammering the coast. The swell sizes actually get quite serious, from 5 feet to 5 feet, and then we see a peak on Saturday the 8th of August with an 8-foot West swell (combined energy over 2000). The period is long, 14 to 15 seconds, which means there's a lot of power. But with the wind howling cross-onshore day after day, it's going to be a messy, lumpy, blown-out mess. Any wave that stands up will be a battle to ride. For a reef break, this setup is honestly more interesting for the kite surfers than paddle surfers. The wave quality is just poor.
There is a tiny glimmer on the very last day, Wednesday the 12th, as the swell drops back to 2 feet, but the wind is still a strong cross-shore. It's not worth the paddle.
So, what's the best on offer? It's a tough call, but I'd have to point to Saturday morning, the 1st of August. The 4-foot, 14-second East swell is the only real groundswell that lines up with the optimum direction, giving the wave some shape. Even with the 9 mph cross-onshore wind, it's the only window where you might find a couple of makeable waves. It's not a standout by any stretch, just the least-worst option. The rest of the forecast is a write-off. You're better off waiting for the next system.
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.
