The Lowdown
Alright folks, Rusty here. Let’s take a hard look at what Blacks Beach has got cooking for us over the next couple of weeks. I gotta be straight with you – this is a tough one. We’ve got a long, dry spell on our hands.
Right off the bat, from now until about the 13th of August, it’s pretty grim. The swell is tiny, mostly around 2ft to 3ft, and while the wind is often blowing straight onshore from the W or WSW, it’s not doing us any favors. The wave energy is all over the place, but mostly weak to moderate, with readings like 165 and 166. The water is a balmy 76°, which is much warmer than normal for this time of year, but that’s the only highlight. The "poor surf conditions" tag is stuck on every session right through to the 14th. It’s a frustrating start.
We do see a bit of a pulse building from the 7th onward, with the combined energy climbing into the 400s and 500s, and a few sessions hitting the 800s by the 14th. The swell direction shifts a touch more to the SSW, and the period gets nice and long – hitting 19 seconds on the 7th and staying in the teens. But here’s the kicker: the wind stays cross-onshore or onshore for most of it, and the wave heights are still only 2ft to 3ft. That long period groundswell at a beach break like Blacks can sometimes make it break a bit straight and closey.
Now, if you’re patient, there’s one window that might get the heart beating a little. On Friday the 14th, we start seeing some "marginal" surf, with the combined energy jumping to 516 on the morning. The real standout, and I’m saying this with caution, looks to be Saturday the 15th of August. We’ve got a consistent 4ft swell from the SSW, with a 16-second period and the wind swinging more WNW, which is still onshore but better. The energy is strong at 708 in the morning. It’s still not perfect, but it’s the best we’re going to get in this whole run. For an advanced spot like this, 4ft is small, but the long period might give it some punch. Expect crowds to be a problem here – it says "often" busy, so get there early.
After that, it drops back down into the 2ft to 3ft range with that persistent cross-onshore breeze right through to the 19th. It’s a lean forecast. Honestly, with the constant onshore and cross-onshore wind and the small, long-period swell, this setup at a beach break might actually look more interesting for the kite surfers than us paddle guys for most of the period.
Keep your eyes on that Saturday the 15th – it’s the only real chance of a decent wave. The rest of the time, you’re better off waxing your board and waiting.
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.
