The Lowdown
Alright, this is Rusty. Let’s have a look at what’s on the table for Blacks Beach over the next couple of weeks, and I gotta be straight with you – it’s a tough stretch to call.
The overall pattern is pretty frustrating. We’ve got a long run of tiny, weak swell and wind that doesn’t want to cooperate. For the next several days, you’re looking at poor surf conditions. There’s a real gap from now, through the middle of the week. Nothing worth paddling out for until we get to Friday, August 14th, and even then, it’s only looking marginal.
The best of a quiet bunch looks to be the Saturday morning, August 15th. The swell is still small at 3 ft from the SSW, but the wind goes almost glassy – a slight air from the WNW, which is about as good as it gets around here. That’s the cleanest window we get, but don’t expect any power. The combined swell energy is moderate (608), so it’s not exactly going to be a world-beater. The water temp is sitting at a very unusual 76°, which is much warmer than normal for this time of year. That’s a bit of a novelty.
Sunday the 16th is similar in size, 4 ft from the SSW, with light offshore wind, but still in that marginal zone. The rest of the run is mostly short-period junk with a cross-onshore breeze. The period on Saturday the 22nd is a weak 8 seconds, and we see a little bump of long-period (18 seconds) groundswell on the 24th, but it’s only 2 ft, so it’s a non-event. This setup just isn’t doing anything for paddle surfing. If the wind picks up, it might look more interesting for kite surfing.
If you’re a beginner, the swell never gets over 5 ft, so it’s not too big, but the quality is so poor it’s hard to recommend. Experts won’t find anything to get excited about either. It’s just a flat, onshore pattern. Crowds can be an issue here, but with this forecast, the beach might be quiet.
It’s a frustrating outlook. Hopefully, the forecasts change, but for now, it’s a waiting game.

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.
