The Lowdown

Alright folks, Rusty here. Let’s get into it.

Alright, so we’ve got a bit of a slow start, but the long-range story is what’s got my attention. For the next few days, don’t expect much – it’s going to be a waiting game until the end of the first week and into the second. The action really starts to build from Saturday the 25th onwards.

First up, we’ve got Blacks Beach. On Tuesday the 21st, the morning session is the only real window. We’re looking at a 3ft SSW groundswell with a very long 16-second period, which brings a moderate combined swell energy of 744. The wind is light and offshore from the WSW, so the surface should be clean. But it’s marginal, and the tide could be a factor. The water temp is about average for this time of year.

The rest of that week is a write-off. Wednesday and Thursday are poor with onshore winds and choppy conditions. The swell drops right off.

Friday the 24th is still marginal, but the morning shows a 2ft SW swell with a long 24-second period, giving a solid 705 combined energy. The wind is a gentle cross-onshore, so it won’t be glassy, but it’s a step up. We’re still in the marginal zone.

Saturday the 25th is where things start to look interesting. The morning has a 3ft SSW groundswell with a 21-second period. The energy jumps to 1159 – that’s a strong pulse. The wind is light and offshore from the WSW, so it’ll be clean. This is the first real standout, but it’s still a few days out. The afternoon is a touch lighter on energy.

Sunday the 26th through Monday the 27th sees consistent 4ft to 4ft SSW groundswell, with periods in the 18-19 second range. The energy stays solidly in the 900-1100 range. Winds are light and cross-onshore, so expect some texture on the surface but still rideable. Crowds are often a factor at Blacks, so expect company.

Tuesday the 28th is the peak of this run. The morning shows a 4ft SSW swell with a 17-second period, cranking out a combined energy of 1337 – that’s strong wave energy. The wind is a moderate cross-shore, so it’ll be a bit bumpy, but the power is there. This is the best on offer in the whole forecast. For experienced surfers, this is the one to circle. The swell is a touch over 5ft, so it’s getting into the intermediate to advanced zone, but under 8ft, so it’s not just for experts.

From Wednesday the 29th into Thursday the 30th, the swell drops back to 4ft, and the energy fades to around 500-800. The wind goes light and offshore, so the conditions will be clean, but the wave height is smaller.

Friday the 31st is a dud – flat with 1.0ft swell and almost no energy.

Then we get a late call. Saturday the 1st of August sees a new pulse of 6ft SSW groundswell, with a 12-second period. The energy is 1029 – moderate to strong. The wind is a gentle cross-onshore, so it’ll be a bit lumpy. This is over 5ft, so it’s pushing into the intermediate-advanced range. It’s a promising option for the second week, but less certain.

After that, the forecast drops off again into small, poor conditions for the rest of the run.

The Bottom Line: The standout is Tuesday the 28th at Blacks Beach. Good size, strong energy, and a solid window. Saturday the 25th morning is a close second for cleaner conditions with less size. The rest is a mix of marginal and small stuff.

Alright, stay safe out there.

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.
