The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this forecast is a tough one. We’ve got a long stretch of barely rideable surf ahead, and it’s going to test your patience. The first standout worth paddling out for doesn’t show up until the afternoon of Friday the 14th of August, so there’s a solid two-week gap where you’re better off leaving the board in the shed.
The only real beacon in this gloom is Blacks Beach (San Diego – United States). It’s an advanced, exposed point break that’s consistent but often crowded, and it loves a good WNW swell. The water temperature is sitting about average for the time of year, so no surprises there.
From Sunday the 2nd of August right through to the morning of Friday the 14th, it’s all poor surf. Tiny waves, onshore or cross-onshore winds, and weak energy readings mostly below 200. It’s grim. The swell period starts short and choppy, then from about the 7th of August, we start seeing longer period swells (17 to 19 seconds) but the height is still only 2 ft to 3 ft, and the cross-onshore breeze keeps it messy. The combined energy climbs into the moderate range from the 9th of August onward, but it’s not doing you any favours with the wind.
Then, on the afternoon of Friday the 14th of August, things start to shift. That’s our first real window. Swell picks up to 4 ft from the SW with a solid 18-second period, and the combined energy jumps to a decent 755. The wind is onshore from the W at 9 mph, so it’s still not glassy, but it’s a marginal improvement. Saturday the 15th of August morning is similar – 3 ft from the SSW, 16-second period, energy of 584, with a light onshore breeze from the W at 6 mph. It’s still only rated as marginal, but for Blacks Beach, that’s the best we’ve got in the whole 16-day window. The swell direction is a little off the optimum WNW, coming more from the SW/SSW, which means the wave quality won’t be perfect, but there’ll be something to ride.
Honestly, this is a lean period. If you’re an expert and you’re desperate, the afternoon of the 14th and the morning of the 15th of August are your only real shots. For everyone else, the wind and swell combo just isn’t coming together. The setup looks more interesting for kite surfing than paddle surfing for most of this run.
Keep an eye on it, but don’t hold your breath. 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.
