The Lowdown
Alright folks, it’s Rusty here, and I’ve been staring at the charts for Blacks Beach. I gotta be straight with you – this outlook is a tough one. We’re looking at a 16-day window where the ocean just doesn’t want to cooperate. The first surf recommendation that’s even worth a mention doesn’t show up until Friday, August 14th, and even then, it’s a real struggle.
For the first ten days, from now through to Wednesday, August 13th, it’s a total write-off. The reports are all “poor surf conditions” with zero scores. The swell is tiny, mostly under 3 feet, and the energy is weak to moderate, ranging from 114 to 469. The wind is light, mostly offshore or cross-onshore, but there just isn’t enough swell to push through. It’s a heartbreaking gap for sure.
Now, on Friday, August 14th we finally see a flicker of life. The morning shows a 3ft SSW swell (18s period) with a moderate energy of 598. The wind is light and offshore from the WSW, so it’ll be clean. The afternoon builds slightly to 3ft (18s) with stronger energy of 711 and still a clean offshore wind from the W. The models are calling it “marginal” with a score of 1 out of 10. It’s not a standout, but it’s the first real chance to get wet.
The Saturday morning, August 15th is the best of a mediocre bunch. We’ve got a 3ft SSW swell, period of 16s, and a moderate energy of 640. The wind is offshore from the WNW at 15 km/h, so it’ll be glassy. The wave comment says “marginal surf forecast,” but with that clean wind and a bit of size, this is the pick of the window. The water temperature is 76°F, which is a whopping 9°F above normal – much warmer than usual for this time of year, which is nice for the paddle out.
After that, it drops back off. The afternoon of the 15th gets a bit cross-onshore and choppy, and the rest of the run through to the 21st is all “poor surf conditions” with tiny, weak swell. The energy values drop back down to 158 by the morning of Friday, August 21st.
So, the honest truth? There’s no real standout here. The best we’ve got is the Saturday morning, August 15th at Blacks Beach. The swell is a small 3ft from the SSW, it’s clean with offshore wind, and the energy is there (640). It’s nothing to blow up your phone about, but if you’re desperate, it’s the only window with a pulse. The long period (16s) means the sets will be clean and powerful for the size, but it’s really only for the advanced crew. Expect crowds because it’s a consistent spot that’s often busy.
The rest of the forecast is a long, flat wait. Keep your eyes on the horizon, 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.
