The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The outlook for the next 16 days at Blacks Beach is a tough one. We’ve got a long stretch of small, messy swell and onshore winds, so don’t get your hopes up for any clean, rippable waves. The whole forecast period is essentially a write-off for quality surf, with the first solid recommendation not showing up until deeper into the second week.
Starting now, through the first week and into the second, the story is pretty much the same: small swell around 1ft to 3ft, mostly from the SSW or SW, with periods that are a mix of short and long. The wind is a constant problem – mostly cross-onshore or onshore from the W, WNW, or WSW, keeping the surface choppy and bumpy. The combined swell energy is weak to moderate, ranging from 224 to 695, but it’s all wasted on the poor conditions. The water temperature is a crazy 76°, which is much warmer than normal for this time of year, but that’s about the only bright spot.
There’s a glimmer of hope on Saturday, August 15th, when the afternoon swell pushes up to 4ft from the SSW with a 16-second period. That’s a groundswell with some decent energy (695), but the wind is a cross-onshore from the WNW at 9 mph, so it’ll be lumpy. It’s still only marginal, but it’s the closest thing to a standout we’ve got. The long period means it’s best for a reef or point break, but at Blacks Beach (exposed, advanced), it’ll just be a faster, more powerful closeout. This is for experts only, as the crowd is often there.
The best day on offer, if you can call it that, is Friday, August 14th, in the afternoon. The swell is 3ft from the SSW at 18 seconds, with the combined energy hitting 628. The wind is onshore from the WNW at 9 mph, but it’s the least messy looking of the whole period. Still, don’t expect perfection.
Honestly, it’s a bleak run. The consistency is there, but the quality is not. For a beach break like this with persistent onshore wind, this setup looks more interesting for kite surfing than paddle surfing. Survive the flat spell, and maybe the forecasts will change.
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.
