The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Overall, we're looking at a pretty drawn-out period of small, weak surf. There's no real punch to anything in the short term, and it's going to take a while for things to get interesting. The first few days are a write-off.
The first real chance of something rideable pops up on Thursday the 20th of August, but even then, it's marginal. We're talking about 3 ft of SSW swell, period around 14 seconds, with a light cross-onshore breeze. It's not going to be clean, and the energy is weak (270). Honestly, it's a day for the longboard or a beach day, not a surf mission.
We've got a long gap here with nothing really worth getting out of bed for. The wind stays light, mostly offshore, but the swell just doesn't have the guts. The water temp is 71°, which is a touch warmer than normal for this time of year, so at least you won't freeze while you're sitting out there staring at flat lines.
Now, let's fast-forward to the end of the month. Things start to look a bit more promising. The 29th of August (Saturday) sees a bump in energy. On the Saturday morning, we've got 4 ft of SSW swell, period 17 seconds, with a light cross-onshore. The combined energy jumps up to 799 – that's moderate energy, but still in the marginal category. The afternoon cleans up with offshore wind, and we get 4 ft of SSW at 16 seconds, with 807 energy. That's the best of the bunch, but it's still on the smaller side.
The Standout: The real highlight, if you can wait, lands on the morning of Sunday the 30th of August. The swell is still around 4 ft from the SSW, period 15 seconds, with moderate energy (650). But here's the thing – the wind is a gentle cross-onshore, which will keep it a bit lumpy. The following Monday morning, the 31st of August, has 3 ft of SSW swell with offshore wind, giving you the cleanest conditions of the whole run, but less size. For the biggest, cleanest windows, keep an eye on the Saturday afternoon the 29th and the Sunday the 30th. The 29th afternoon with the offshore breeze and 4 ft swell is the best bet, but at that size, it's fine for most surfers, not just experts. Just know that Blacks Beach can get crowded often, so get out there early.
If the wind picks up more than forecast on those bigger days, this setup might look more interesting for kite surfing than paddle surfing.
So, hang in there. The first week is a bust, but there's a little pulse coming for the final weekend of August. It’s not going to be epic, but it's surfable.

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.
