The Lowdown

G’day, Rusty here. Look, I gotta be straight with you – the next couple of weeks aren’t exactly firing around Blacks Beach. We’ve got a long stretch of small, average-to-poor conditions ahead, so don’t get your hopes up too high. The best of what’s on offer is a late-breaking window right at the very end of the month and into the start of September.

We kick off from Tuesday, 18 August with a clean but pretty weak little 2ft SSW groundswell rolling in. The period is a solid 16 seconds, which is proper groundswell, and the wind is light and offshore from the west – that’ll keep the surface glassy. But the combined wave energy is only moderate at 397, and the surf is real marginal. It’s barely breaking with any punch. Wednesday the 19th sees a slight bump to 3ft from the same SSW direction, still with that long 16-second period and offshore west winds. The energy creeps up to 475, but it’s still a marginal call – nothing to get excited about.

Then we hit a real flat spell. From Thursday, 20 August through to Wednesday, 27 August, it’s mostly 2ft to 3ft rubbish. The swell direction swings from SSW to SW, periods drop a bit, and the wind goes cross-on or just onshore. The energy levels are weak to moderate – think 201 to 364. There’s a couple of moments on Saturday, 22 August afternoon (3ft, 14s, 364 energy) and Sunday morning, 23 August (2ft but a very long 19-second period, 340 energy) where it’s clean, but the size just isn’t there. It’s a paddler’s dream for exercise, not for getting barreled. This stretch is a big gap of no real recommendations – about a solid week of nothing worth racing down for.

Now, Thursday, 27 August morning shows a weird spike: 4ft from the west, but with a short 8-second period and energy of 410. That’s a weak, choppy windswell, and the wind is cross-on from the SW. Not good – only one for the die-hards. That afternoon drops back to 1ft.

Here’s the standout window. From Saturday, 29 August through to Monday, 31 August, we finally see a proper lift. Saturday morning has 3ft from the SSW with a very long 18-second period – that’s proper groundswell energy building to 809. The wind is a light cross-onshore, so expect a few bumps, but it’s still manageable. Saturday afternoon gets better: 4ft, 17-second period, energy jumps to 883, and the wind switches to a light offshore from the west. That’s clean, lined-up surf – the best of the whole forecast.

Sunday, 30 August is similar: 4ft SSW swell, 16-second period, and energy hits 951, but the morning has a light cross-onshore breeze. Still, that’s punchy and consistent for a point break like Blacks. Afternoon stays at 4ft with a 15-second period and west-southwest offshore winds. The energy is still strong at 685.

Monday, 31 August morning drops a little to 3ft (14 seconds, 515 energy) with a gentle cross-onshore, making it a bit choppy. Afternoon cleans right up with west offshore winds, but the swell fades to 3ft.

After that, Tuesday and Wednesday of the first week of September are back to the same old story: 2ft to 3ft dribble with light onshore winds. Not worth the wetsuit.

The water temp anomaly isn’t given in the data, so I’ll just say it feels about what you’d expect for this time of year around Blacks Beach – not unusually warm or cold.

The best call? Saturday, 29 August afternoon and Sunday, 30 August morning at Blacks Beach (San Diego). You’re looking at a consistent 4ft to 4ft of clean SSW groundswell with that long period, light offshore winds on Saturday arvo, and solid energy (883 to 951). Quality is marginal on paper, but in context, it’s the pick of a pretty average two weeks. Crowds can be an issue here – it’s a famous spot – but in these small conditions, it should be manageable. If you’re an advanced surfer, this is your window. Beginners might find the 4ft a bit much, but it’s not massive.

That’s the long and short of it. Stay patient, and keep an eye on that last weekend of August.

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.
