The Lowdown
Alright folks, Rusty here. Let’s talk about what’s happening at Blacks Beach over the next couple of weeks. The long story short is, it’s a pretty quiet stretch. We’re not looking at any proper standouts, but there are a few windows where the conditions might be worth a paddle.
We start off the period on Saturday, 29th August, with a small SSW swell. The waves are around 4ft to 4ft, but the period is a long 16 seconds, which gives it some push for its size. The combined wave energy is moderate at 731 to 845. The wind is offshore from the west, so the surface should be clean. The water temp is about average for this time of year. That said, the overall forecast score is low, so it’s a marginal session at best.
Sunday the 30th is similar in size, 4ft from the SSW, but the wind swings to a cross-onshore, making it choppy. The energy drops a bit through the day. Things go downhill from there. From Monday, 31st August, right through to the 7th of September, we’ve got a run of poor to marginal conditions. Swell size hangs around 2ft to 4ft, but the wind is mostly cross-onshore or onshore, and the energy is weak to moderate (219 to 821). Not really worth getting excited about.
Now, the only thing that looks a bit different is on Tuesday, the 8th of September. We get a bump in swell – 8ft from the SSW early in the morning, with a short period of 11 seconds. The combined energy jumps to 1615, which is strong. The wind is cross-offshore from the south, so the surface is clean. But here’s the catch – that’s a solid size for Blacks Beach, and it’s a beach break, so it’s going to be a heavy, powerful wave. This is definitely one for the advanced crew only. The swell direction is SSW, which isn’t the optimum WNW for this spot, and the short period means it’ll be a bit messy and inconsistent. Later that afternoon, the swell drops to 6ft, but the wind picks up to a strong breeze from the SSE. It’s still clean, but the wave shape will be tricky.
After that, from the 9th of September onward, it’s back to small, weak swells (2ft to 3ft) with poor conditions. The wind is mostly onshore or cross-onshore, and the energy is low. Nothing to recommend.
So, overall, the best of a quiet bunch is the morning of Saturday, 29th August, with clean offshore winds and a long-period swell, but it’s small. The only real punch of size comes on Tuesday, the 8th of September, but that’s expert-only territory. The rest of the 16 days is a long, flat gap. Keep the board waxed and check the forecasts, but don’t hold your breath.
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.
