The Lowdown

Alright, this is Rusty. Let's talk about what's on offer for Blacks Beach.

Alright, folks, it’s a tough stretch ahead for Blacks Beach. We’re looking at a long, dry spell here. The surf is going to be pretty quiet for the majority of the next 16 days. There's a bit of a pulse trying to show up, but the conditions are just not playing ball. The water is sitting at a warm 72°F, which is much warmer than normal for this time of year—a little tropical treat while you wait for something to ride.

The first real chance to get wet might be on Monday morning, the 7th of September. We’ve got a solid 6ft swell rolling in from the SSW, carrying a heavy 1085 (moderate to strong energy) punch. The period is a nice 13 seconds, so there’s some real groundswell grunt behind it. But here’s the kicker: the wind is cross-onshore from the WNW at 9 mph. It’s going to be fairly choppy. It’s only for the experts, and the forecast calls it marginal. The direction is a little off from the optimum WNW, so it’s not going to be at its best.

Tuesday morning, the 8th, is similar. The swell drops to 5ft from the SSW, with a period of 11 seconds and 663 energy (moderate). The wind is still cross-onshore from the WNW at 9 mph, keeping things choppy.

The one standout, if you can call it that, is Thursday afternoon, the 10th of September. The swell is a clean 3ft from the SW, but the period jumps to a very long 16 seconds. That’s proper groundswell. The energy is moderate at 553. The key here is the wind: it’s light from the SW at 6 mph, still cross-onshore, but with barely a ripple. This is the cleanest it’s going to get. The swell direction is also a perfect match for the optimum SW. For a patient surfer on a longboard, this could be a glassy session, but it’s still a marginal call due to the small size.

After that, it’s a wasteland. From the 11th of September right through to the 21st, the swell is small, the period drops off, and the wind is almost always a mess. We see a few days with a 3ft to 3ft swell from the SW or W, but the energy is low and the wind is either cross-onshore or onshore. There’s a brief flicker of hope on the 21st of September (Monday) with a 3ft SW swell, 16-second period, and a very light wind from the SW at 3 mph, but it’s cloudy and still classed as marginal.

Honestly, this is a tough block. The exposed nature of Blacks Beach means it picks up everything, but also the wind. The best bet is to keep an eye on Thursday afternoon, the 10th, for a long-period, clean-ish wave. The rest of the time, it’s a waiting game. It’s not a bad run of weather for a beach day, but for surf, it’s a grind.

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.
