The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.
To be straight with you, this outlook is a tough one. There’s a big dry spell coming up. For the first stretch, from Monday the 27th of July right through to the end of the month, we’re looking at tiny, weak swell. We’re talking ankle-to-knee high waves at best, with the combined energy barely registering above 20 (24) in the mornings. The wind is mostly cross-off or light, but there just isn’t enough swell to get excited about. The water temp is about average for this time of year, so nothing unusual there.
We get a tease of something bigger later on. Saturday the 1st of August sees a pulse of 4ft swell from the east, with a decent 14-second period. The combined energy jumps up to 472 – that’s a proper bump in energy. But here’s the kicker: the wind is onshore from the northwest, and it’s a risk of thunderstorms setup. The wave comment says “poor surf conditions,” and honestly, that onshore breeze will chop it up. It’s not a runner.
The best of a bad run looks like it might be Sunday the 2nd of August. Swell holds at 4ft to 4ft from the east-northeast, with that same long 14-second period, and the combined energy is strong (522-651). But again, the wind is a moderate cross-onshore from the west, making it choppy. It’s a shame, because there’s energy there, but the wind is just not our friend.
After that, the pattern stays messy. Through the first week of August, we’ve got consistent chest-high swell (3ft to 5ft) with long periods (14-16 seconds), but the wind remains cross-onshore or onshore from the west-southwest, gusting up to 18-19 mph. The wave comment flags it as “poor surf conditions” and “fresh cross-onshore and lumpy.” This is one of those setups that looks more interesting for a kite surfer than a paddler, honestly. The break is a reef, so it might handle the chop better than a beach, but it’s still not clean.
The second week, from the 6th of August onwards, the swell drops back to 3ft to 3ft, with a shorter period (11-13 seconds), and the wind stays stubbornly cross-onshore. It’s consistent but never clean. The combined energy is moderate (200-400 range), but it’s all just messy.
There’s no standout session here. The best on offer is probably the morning of Thursday the 30th of July, when the wind goes glassy with a light west-northwest breeze, but the swell is only 2ft. It’s clean, but not enough to surf. If you’re desperate, the 1st-2nd of August has the size and period, but the wind ruins it. I’d wait for a better forecast.
This is a reef break that’s known to be inconsistent, and this run is a perfect example of that. It’s a blank spell for the area, but forecasts can change. Keep an eye on it.
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.
