The Lowdown
Alright, let’s get into it. The 16-day window kicks off with a bit of a flat spell. We’ve got a solid run of small, weak surf coming in from the southwest, but honestly, it’s not doing much for us. The energy readings are mostly in the 200-400 range, which is weak, and the swell heights are hovering around 2ft to 3ft. The wind is mostly onshore or cross-onshore, so it’s going to be pretty chopped up and messy. Those first couple of weeks are a write-off for any real quality. We’re looking at maybe 12 days of this pretty average stuff before anything gets interesting.
The only spot with any real name on it in this forecast is Blacks Beach (Palm Beach). It’s an exposed break, and it’s consistent. But with the swell that weak and the wind like that, even a good break will struggle. The water is running about 74°, which is a full 5° warmer than normal for this time of year. That’s a standout – the water is properly warm.
Around the 21st and 22nd, we see a small bump in the swell, but it’s still in the 2ft to 3ft range with those short 13-second periods. Not enough to get excited about. The real shift comes on the 27th of August. The morning sees a jump to 7ft of southwest swell, and the energy readings jump to 1376. That’s a strong pulse of energy, a real groundswell. The wind is onshore, but it’s only 9 mph, so it might not completely kill it. However, that size at Blacks Beach is more on the expert side of things.
The following days, the 28th and 29th, keep the momentum going. We’re looking at 4ft to 5ft of swell with periods of 13-18 seconds. The energy is still high, in the 800 to 1000+ range. The wind is lighter, with a bit of a cross-on feel, but still manageable. The 29th looks like the pick of the bunch, with 4ft of SSW swell at 18 seconds and light winds. That’s a solid, powerful long-period swell with clean conditions. That’s the one to circle on the calendar.
Before that, the conditions are just poor. The swell is too small, the periods are too short, and the wind is messing things up. It’s not worth getting wet for. For the first two weeks, you’re better off doing something else. But that last stretch, particularly the 29th, has some real potential. It’s a promising window, but it’s far out, so it’s not a sure thing just yet.
This is Rusty, signing off.

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.
