The Lowdown
Alright, folks, Rusty here. Let’s chew the fat about what’s coming down the pipe for the next couple of weeks. It’s a bit of a slow burn, so don’t rush to wax your board.
First off, the water is a warm 73°F – that’s about 5°F warmer than usual for this time of year, so it feels like a bath. Nice little bonus.
The overall pattern is a slow start. The next few days are pretty flat and messy. We’re looking at a stretch of so-so to poor conditions from now through the end of the month. The swell is tiny, mostly 2ft to 3ft, with a long period groundswell from the SW, but the wind is a constant cross-on or onshore. It’s choppy, and the energy is weak to moderate (208 to 360). Nothing to write home about. The combined energy is moderate, but the quality just isn’t there.
Things get a little pulse around the 29th and 30th. Saturday morning the 29th brings a 4ft SSW swell (16 seconds) and light offshore wind, which is a big step up. The combined energy jumps to 797, a solid moderate wallop. It’s still a bit marginal, but it’s the first real sign of life. Sunday morning the 30th is similar, with a 4ft SSW swell, but the wind is cross-on and the energy drops to 675. Still, not a bad little window.
Now, the standout window is shaping up for Wednesday, 2nd September. That morning the stars almost align. We’ve got a 3ft SSW swell, a period of 11 seconds, and – get this – glassy, zero wind conditions. That’s the cleanest we’ll see. The combined energy is 426, which is moderate, but the glassy surface makes it rideable. The break is Blacks Beach, an exposed spot that takes a WNW optimum direction, but this SSW swell is still hitting it. The water is warm, the crowds are *often* there, so expect company. The swell is small, so it’s a fun size for a busy line-up.
After that, the second week is a bit of a fade. Thursday the 3rd and Friday the 4th offer some 3ft SSW swell with light onshore winds, but the energy is moderate (549 to 787). It’s a bit bumpy, and the ratings are low. Then it drops off. The 5th and 6th have some 4ft and 3ft SSW swell, but the wind is onshore and the scores are poor. The long period (16-17 seconds) for a beach break like Blacks means it’ll be a bit straight and fat, better suited to the sandbanks if they’re holding. But overall, the second week is nothing to write home about.
There’s a big gap of poor conditions from the 6th to the 9th of September. The swell is small, the wind is onshore or cross-on, and the energy is low. The only real highlight is the glassy morning on the 2nd of September. Keep an eye on the forecasts, but for now, that Wednesday looks like the best bet.
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.
