The Lowdown
Yo, Rusty here. Let’s get straight into it. The next 16 days are looking pretty grim for Blacks Beach, to be honest. There’s a whole lot of poor surf conditions with only a couple of tiny windows that might be worth a look if you’re desperate. The water is running much warmer than normal for this time of year, coming in at 76°F on the 5th, which is a real anomaly (about 9°F warmer than usual). That’s very unusual.
Right off the bat, the first option is on Wednesday afternoon, August 5th. Swell is tiny at 2 feet from the SW, with a period of 14 seconds – that’s a long period groundswell, but the energy is just weak (168). The wind is offshore from the W at 9 mph, which is clean, but the wave comment says it’s poor surf. Honestly, it’s not worth paddling out for.
Thursday the 6th through to the 18th is a long stretch of nothing special. Swell stays low, mostly around 2 to 3 feet, and while the wind is often offshore or light, the wave quality is consistently described as poor or marginal. There’s a little bump on Friday morning, August 7th, with a 2-foot SSW swell and a period of 19 seconds – that’s very long period, and the energy picks up to 500 (moderate), but it’s still only a marginal call. The wind is light offshore from the W, so it’ll be clean, but the tiny size and that long period won’t do much for a beach break like this. It’ll likely just be a slow, straight wave.
The only real standout in the whole window is the afternoon of Saturday, August 15th. Swell bumps up to 4 feet from the SSW, with a period of 16 seconds and a combined energy of 805 (strong). The wind is offshore from the WNW at 9 mph, so it’ll be clean. But even then, the wave comment is still “poor surf conditions,” so don’t expect magic. It’s the best on offer, but that’s not saying much. For an advanced spot like Blacks Beach, this is frustratingly small and weak.
From the 16th onwards, it’s back to tiny, poor surf. The 18th and 19th have some cross-onshore winds, so it’ll be choppy and messy. The last day, Thursday, August 20th, is a cross-onshore wind with 2-foot SSW swell – not worth the drive.
Bottom line: there’s a 10-day gap of mostly poor surf before the small bump on the 15th. If you’re a beginner, the swell never gets over 5 feet, so it’s safe, but the quality is so low you’ll just be floating. For experts, it’s a waste of time. The whole period is a write-off. Keep your board waxed and wait for the next system.
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.
