The Lowdown
G’day, Rusty here. Let’s be straight about Round Rock. It’s one of those spots that can fire under the right conditions, but for this entire 16-day stretch, the story is pretty grim. There are no standout days, no hidden gems. Conditions are persistently poor, and the window for anything even vaguely rideable is tiny.
The first surf we can even talk about doesn’t kick off until Tuesday morning, 18th August – and even then, it’s a marginal call. You’re looking at small, weak swell at 4ft from the ENE with a short period of just 8 seconds. The wind is a light cross-onshore, which is as good as it gets, but with combined wave energy chugging along at a measly 254 (moderate energy), it’s nothing to get excited about. The water is sitting at 84°F, almost bang on average for this time of year, so at least the bathwater is warm.
After that, the outlook gets worse. From Tuesday afternoon onward, it’s all cross-onshore winds, mostly fresh to moderate breezes, and lumpy, choppy seas. The swell direction never shifts significantly, staying locked in the ENE, while the optimum direction for Round Rock is from the north. That’s a fundamental mismatch. The period is short (7-8 seconds), meaning weak, wind-affected waves that won’t hold shape.
Even when the swell pumps up a bit on Monday 24th August – with a solid 10ft from the ENE and a very long period of 14 seconds, giving you 2933 (very strong energy) – the wind is a fresh cross-onshore, making it a messy, lumpy beast. That size is only for experts, and with those winds, it’s going to be a challenge even for them. The direction still isn’t ideal.
The final few days of August and into the 31st offer nothing. The swell drops to 4-4ft, period slips to 6-7 seconds, and the wind stays relentless from the east. It’s just not worth paddling out.
Round Rock is a consistent spot normally, so this long, flat, windy run is a bit of a shock. But forecasts change, so don’t lose hope entirely. For now though, with the persistent cross-onshore wind, poor surf quality, and a beach-and-reef setup, this stretch is way more interesting for kite surfing than paddle surfing.
Rusty.

Information about the Round Rock Surf forecast
The above surf forecast table for Round Rock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Round Rock can be found by selecting the local surf guide option on the grey menu. Our Round Rock 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 (Round Rock) 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 Round Rock 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.
