The Lowdown

G'day, Rusty here. Look, I've gotta be straight with you—this stretch is looking pretty grim for a while. We're staring down a long dry spell with hardly anything worth paddling out for. Let's break it down.

For the next week and a half, from Monday the 17th of August right through to Thursday the 27th of August, it's a total write-off. The swell is tiny, mostly around 2ft to 3ft out of the SSW or SW, with periods that are a mixed bag—some short, some long. The wind is almost always onshore or cross-onshore, keeping things choppy and messy. The combined wave energy is weak to moderate at best (values between 180 and 477), and the surf reports are all "poor" or "marginal." There's a whole lot of nothing happening.

Now, after that long gap, we finally get a glimmer on Thursday the 27th of August. The morning at Blacks Beach shows glassy conditions with a light S wind at 3 mph, and the swell is 2ft from the SW with a period of 14 seconds. The combined energy is 285, which is still on the lower side, but that glassy wind is a massive positive. It's not going to be big, but it'll be clean. For a short window, it's the best we've got.

Then, another gap until Sunday the 30th of August. That morning offers the standout moment of the entire outlook. The wind goes calm—dead flat—making it glassy as can be. The swell is 3ft from the SSW with a 15-second period, giving it a long-period groundswell feel, and the combined energy reads 433, which is moderate. The direction is a bit off from the optimum WNW, but with that glassy surface and the consistent nature of Blacks Beach, it's the one session worth circling on your calendar. Keep in mind, this is a consistent spot, so when it's on, it's on. But don't expect much else—the rest of the month is a bust.

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.
