The Lowdown
Alright folks, Rusty here. I’ve been staring at the charts for this one spot and it’s a bit of a mixed bag. Let’s get into it.
The next few days are looking pretty average at best, but there’s a bit of a pulse later that might get the blood pumping. For the first part of the week, we’ve got a solid, long-period groundswell running but the wind is letting us down. Tuesday the 27th and Wednesday the 28th see a consistent 4ft swell from the SSW with a period of 17-18 seconds, which is a proper long-period groundswell. The wave energy is strong, sitting at 1129 and 1221, but the wind is blowing cross-onshore from the SW at 9-10 mph. That’s making it choppy and the reports are calling it marginal. It’s a shame because the swell has real potential, but with that wind, it’s going to be messy. The water temp is about average for this time of year, so no surprises there.
Things go downhill from Thursday the 30th through to the weekend. The swell drops right off, with heights under 3ft and periods under 10 seconds. The wave energy is weak, in the 20-30 range, and it’s poor surf conditions. Basically, a flat spell. That gap lasts from Thursday the 30th all the way through to Saturday the 8th of August. There’s a tiny bump on Friday the 31st with a 5ft SSW swell and a 13-second period, but the energy is still moderate at 982 and the wind is onshore from the WNW. It’s just not happening.
The real standout, and the only one worth paddling out for, is the morning of Saturday the 8th of August. We’ve got a 3ft SSW swell with a 16-second period and the combined energy is moderate at 547. The wind is switching around to the W at 9 mph, which is blowing straight onshore. The break is exposed to the WNW, so this swell is wrapping in nicely. The guidance says this spot is a consistent, advanced-level wave that handles the WNW swell direction perfectly. The wind being onshore is a bummer, but if it stays light, there could be a window. This is a long-range call, but it’s the best we’ve got on offer. The rest of the second week is just small, weak, and onshore.
Let’s be honest, for the first half of this forecast, it’s a struggle. The pics won’t look good. If you’re a beginner, stay away when it’s over 5ft and definitely when it’s over 8ft – but that’s not an issue here. The long period from the SSW will be better at reefs and points, but with the wind as it is, it’s going to be a kite-surfing show more than a paddle session. The setup is a beach break, so those long-period swells will just break too straight.
We’ll keep an eye on that Saturday the 8th of August window. It’s not guaranteed, but it’s the only glimmer of hope.
Rusty.

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.
