The Lowdown

Alright, Rusty here. Let’s talk about what’s on the cards for the next couple of weeks.

It’s a bit of a flat, frustrating run ahead, to be honest. We’re looking at a long stretch where the surf is just not playing the game. The first decent swell window isn’t until Friday the 14th, and even then, it’s only just poking its head above the marginal line. Before that, from Wednesday the 12th through to Thursday the 13th, the conditions are poor – small, weak waves and onshore wind. Don’t bother paddling out.

Things start to look a little more hopeful from Friday the 14th morning. We’ve got a SSW groundswell coming in with a period of 18 seconds – that’s proper long-period energy – pushing 2ft to 3ft. The combined energy is building into a moderate range (547 to 734). The wind is onshore but light from the W, so it won’t be glassy but it’s workable. This is marginal surf, but for Blacks Beach, those long-period SSW swells can wrap in with some shape. The tide will be a factor, so keep an eye on that.

Saturday the 15th keeps the same theme. The swell picks up a touch to 3ft to 4ft from the SSW, still with a long 16-second period. The wind stays light and onshore from the W. The combined energy is solidly moderate (621 to 706). Again, it’s marginal. The water temperature is a notable 75°, which is much warmer than usual for this time of year.

Sunday the 16th is a step down. The swell drops back to 3ft, the period shortens to 15 seconds, and by the afternoon the wind swings a bit more northerly. The energy drops (517 to 476). It’s still in that poor to marginal range. Monday the 17th and Tuesday the 18th are similar – small, weak, and poor. Wednesday the 19th sees the wind turn cross-onshore from the SW, making it choppy.

From Thursday the 20th right through to Monday the 24th of August, it’s mostly poor. There’s a tiny spike on Wednesday the 26th, with a 3ft to 4ft SW swell and a 16-second period, giving us the highest combined energy of the whole forecast at 587. The wind is light and onshore from the W, so it’s about as clean as it gets for these conditions. This is the best looking window in the whole run, but it’s still only a marginal 2 out of 10. Thursday the 27th brings a moderate cross-shore wind from the S, which won’t help.

The standout: If you’re desperate for a paddle, the morning of Friday the 14th and the morning of Saturday the 15th offer the best combination of size, period, and clean-ish wind. But honestly, it’s a tough call. The water is warm, the swell is small, and it’s a long period groundswell which can be tricky on a beach break like Blacks. It might offer some clean lines if the tide is right, but don’t expect any barrels. For the rest of the run, you’re mostly looking at ankle-biters and poor conditions.

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.
