The Lowdown

Alright, surfers, Rusty here. Let’s get into it. We’ve got a tricky 16-day window ahead for Blacks Beach, so let’s break it down.

Right off the bat, the first few days are a bit of a letdown. Friday the 4th and Saturday the 5th have some small, long-period SSW groundswell in the 3ft to 4ft range, but the surf is marginal, with questionable tide conditions. The wind is variable, but it’s not lining up perfectly. The combined energy is moderate, sitting around 668 to 781, but it’s just not enough to get excited about. Sunday the 6th is a write-off with poor conditions and tiny swell, so you can leave the boards in the car.

Now, hold onto your leggies, because Monday the 7th is where things get interesting. The swell jumps up to 7ft from the SSW with a 14-second period, and the combined energy rockets up to 1683 – that’s some serious power. This is a strong, long-period groundswell. For Blacks, a point break, this long period is a big plus, meaning better shaped waves and more energy. The wind is light WNW, which is offshore for Blacks, so the morning session should be clean. This is a standout for experts only, as 7ft gets heavy, and Blacks is an advanced wave. The crowd factor is listed as "often," so expect company, but the quality will be worth it. The water temperature is about average for the time of year.

Tuesday the 8th holds on, with a 6ft SSW swell in the morning dropping to 6ft in the afternoon. Combined energy is still strong at 1352 and 1068. The wind stays offshore in the morning, though it gets a little cross-on in the afternoon. This is another solid day, but the best window is Monday morning.

After that, the swell fades fast. From Wednesday the 9th onward, we’re looking at a long stretch of small, weak surf. The combined energy drops below 600, and by Friday the 11th, the conditions turn poor. From the 12th of September through to the 19th, there’s a real dry spell. The swell height hovers around 1ft to 3ft, with periods all over the place, but the energy is weak, mostly under 400. The wind is often offshore, but there’s just no wave power to work with. It’s a blank run of about 8 days, which is a long gap.

The only faint glimmer at the tail end is Saturday the 19th, where the morning shows a 3ft SW swell with a 19-second period, and combined energy at 576. It’s marginal, but with light offshore winds, if you’re desperate, you might find a longboardable knee-high wave. But don’t get your hopes up.

To wrap it up: the standout is Monday the 7th of September, with a strong, long-period SSW groundswell and offshore winds for the morning. Tuesday the 8th is a solid second option. Everything else is a bust until the very end.

Rusty out.

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.
