The Lowdown
Alright folks, Rusty here. Let's break down what Blacks Beach has in store for the next couple of weeks. It's going to be a slow start, so don't get your hopes up just yet.
For the first week, from Sunday the 23rd right through the end of August, it's looking pretty grim. The swell is tiny, mostly around 2ft from the SW, and the wind is a constant headache. It's blowing cross-on or onshore almost the whole time, messing up the little energy we have. The wave energy is weak to moderate, reading between 208 and 789. Honestly, there's nothing here worth paddling out for. It's just a frustrating wait.
Now, things start to look a little more promising as we roll into the first week of September. On Thursday the 3rd and Friday the 4th, we finally see a bit of a lift. The swell pushes up to about 4ft, still from the SSW, but the period stretches out to a solid 19 seconds – that's proper groundswell energy. The combined energy jumps up to a strong 825 (897 on Friday morning), and the wind is a light cross-onshore. It's still not perfect, but it's a huge step up from the junk we've been dealing with. Keep an eye on that Thursday afternoon and Friday morning window.
However, the real standout of this whole forecast, and I mean the only one worth circling on your calendar, is Saturday the 5th of September. The swell holds right around 4ft from the SSW, still with that nice long-period feel. The wind on Saturday afternoon swings to a light offshore, which will clean things up beautifully for the beach break. That’s the best wind we’ll see for this whole outlook period. The combined swell energy reaches a strong 947.
Blacks Beach is a consistent, exposed spot that handles a south swell well, so it should be breaking cleanly. The wind and swell direction line up, making for what should be a really good day out there. It's advanced-level surf, and with the better conditions, expect the crowds to turn up – it’s often busy here for good reason. If the water temp is about average for the time of year, it’ll feel just fine.
After that Saturday session, it drops off again. The swell fades back down to about 3ft and smaller into the second week, with the wind getting messy again. Sunday the 6th and Monday the 7th offer just marginal conditions, nothing to get too excited about.
So, the long and short of it: suffer through the first week because it's a total write-off. The real action is a single standout day on Saturday, the 5th of September. That’s your chance to get some clean lines, so make sure you're there.
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.
Blacks Beach is 13 km (8 miles) from the city of San Diego. If you plan a vacation in San Diego County, look for hotels and other accommodation in San Diego. San Diego has rooms for a wide range of budgets as well as car hire and transport links.
