The Lowdown
Alright folks, Rusty here. Let’s get into what Black Rock's got in store.
Straight up, this exposed advanced reef break on the NE side is facing a pretty lean two weeks. The first week is basically a bust with mostly poor surf conditions and nothing calling my name. There’s a real dry spell at the start.
We start Saturday the 15th and Sunday the 16th with a tiny 1ft swell out of the ENE. Water temp is about 68°, right on average for the season. But with rain showers and cross-shore breezes, it’s just choppy and not worth the paddle.
Monday the 17th sees a bit of a bump from the ESE, hitting 6ft, but with a short 8-second period and onshore wind, the wave energy is moderate (401). It’s too blown out and messy. It stays in that 5ft to 6ft range through Wednesday the 19th, but the wind stays ugly, and it’s all marked as poor conditions.
By Wednesday morning the 19th, the swell from the SE is 5ft with a longer 11-second period—that’s a groundswell—pushing the energy up to a strong 653. But it’s still cross-shore, and it’s only rated marginal. That’s the only real pulse of energy in the whole outlook, but the conditions just aren’t there to make it work. No standout here.
Into the second week, things drop off even more. From the 22nd to the 25th, we see a slight improvement in wind, but the swell drops to 4ft and under with periods falling to 7 seconds. The combined energy slips down into the double digits. By the 24th and 25th, it’s back to 3ft slop with weak energy. A real flat spell.
From the 26th of August straight through to the 30th, it’s a dead run. Swell barely hits 2ft, and the energy is often below 100. The morning of the 30th shows a 0.3ft, 14-second period groundswell, but with only 15 energy? That’s not going to do a single thing on this reef.
So, bottom line—there’s no standout session in this 16-day window. If you’re desperate, Wednesday the 19th morning is the closest thing to a pulse, but even that’s a long shot. For now, leave the board in the car. Forecasts can change, but this one looks like a long, quiet stretch for Black Rock.
Rusty out.

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