The Lowdown
Alright folks, let's get into what's on the table for your local stretch.
Alright, let's be straight up – the surf is pretty grim for the first few days around here. We're looking at a blank run for Wednesday afternoon the 22nd and all through Thursday the 23rd, with small, messy, choppy conditions that are just not worth paddling out for. The water's sitting at a touch warmer than normal for the time of year at 77°, but that's about the only positive. The real action doesn't start to show until later.
Things start to look a bit more promising by Friday afternoon the 24th. The wind will be light and cross-offshore, cleaning up some small 5ft swell. The combined wave energy is weak (798), but it’ll be a clean, if small, window for a cheeky session.
Now, the standout period arrives on Monday the 27th. Monday morning is the absolute pick of the bunch. There's a solid 7ft SW groundswell with a long period of 16 seconds, and the wave energy is strong (2568). The wind is a light, clean cross-offshore from the NE, making for excellent conditions. This is a serious swell, one for the experienced crew, and it’s going to be good. Expect great shape and plenty of energy, though with that long period, it might be a bit walled-off at the beachies but absolutely firing on the reef. Keep in mind, Black Rocks can be inconsistent and the crowds are sometimes a thing, so get in early.
Monday afternoon gets a bit of rain with it, and the swell stays chunky at 8ft. The wind stays cross-off, so there are still waves to be had, but the morning window is the one to chase. The rest of the week into the start of August offers waves of similar size, but the wind turns more cross-shore, which is never as good as that light offshore we had. It's the kind of window that looks more interesting for a kite session than for a pure paddle, with strong ESE winds on some days.
Looking further into the second week, the pattern holds with more 5ft to 7ft SW swell, but the wind stays mostly cross, keeping the quality messy. It’s a case of watching and waiting for another solid window, but nothing as clean as that Monday the 27th pop up in the longer range.

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