The Lowdown
Right, let’s have a look at what’s in store for the next couple of weeks. First up, we’ve got a bit of a slow start. There’s no decent surf on offer for the first three days until we get to Saturday the 29th of August. Even then, it’s not firing on all cylinders.
Alright, Saturday morning the 29th sees a long-period groundswell roll in at Blacks Beach. It’s a 4 ft SSW swell with a 16-second period, giving the water some real push. The wave energy is moderate, coming in at 728. The wind is light from the W at 6 mph and blowing directly offshore, so the wave faces should be clean and glassy. The water is sitting at 76°, which is a massive 8° warmer than normal for this time of year – that’s very unusual and feels more like a summer bath. Conditions are described as marginal, so you’ll have to pick your tide and your take-off spot. The big caveat here is that this is an exposed beach break. With that long 16-second period, the sets will be well-spaced and powerful. It might be a bit straight, so look for the deeper bowls or any hint of a rip to get you out.
Over the next few days, the swell hangs around but the quality doesn't really lift. Wind stays onshore or cross-onshore through Sunday and Monday. The wave energy dips down into the 173 to 333 range, which is low. This stretch looks like a write-off for a good paddle session. You might see the odd 2 ft to 3 ft wave, but it’d be weak and choppy.
Things perk up a bit on Wednesday morning the 2nd of September with a 4 ft SSW swell and a 12-second period. The energy climbs back to 591 (moderate), and the wind is offshore from the WNW, 9 mph. Again, it’s on the marginal side but that's the cleanest window until the next pulse.
The real standout in the whole window lands on Tuesday the 8th of September. The morning brings a solid 8 ft swell from the SSW with a 13-second period. The combined energy jumps way up to 2103 – that’s strong to very strong. This is proper size. The wind is offshore at 6 mph from the WNW, which will hold the waves open. Now, at 8 ft, this is expert territory only. The period is solid but not super long, so it should pitch nicely rather than just stand up too straight. This is your best shot in the whole outlook – a serious groundswell with clean offshore conditions. Set your alarm.
After that, the swell fades quickly. Wednesday the 9th has a 5 ft swell but the wind is cross-onshore, making it choppy. From Thursday the 10th through to the end of the forecast on Sunday the 13th, it’s all poor or marginal conditions with small waves and mostly cross-onshore winds. The energy drops away to between 193 and 570. That final stretch is a long gap of flat to weak, choppy junk.
If you’re an experienced surfer, that Tuesday the 8th of September morning is the one to chase. For everyone else, you’re looking at a long wait and not much else.

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