The Lowdown
Alright, this is Rusty checkin' in from the Blacks Beach corner. Water temp is sitting at a balmy 75°, which is a solid 7° warmer than usual for this time of year. That's a proper anomaly – feels like a tropical bathtub out there, so you can leave the thick wetsuit at home.
Honestly, I've gotta be straight with you – the next couple of weeks are looking pretty grim for a decent paddle. We've got a long stretch of poor surf conditions ahead. The energy in the water is mostly weak to moderate, with the combined swell energy reading around 299 to 734 (moderate), but the quality just isn't there. The swell is hanging around 2ft to 4ft, mostly from the SSW or SW, with periods that are respectable – between 14 and 18 seconds, which is solid groundswell. But the wind is the real killer here. Through most of the week, it's a steady 9 mph from the west or southwest, which means onshore or cross-onshore breezes, creating choppy, messy conditions.
The real standout, the only window that even gets a nod, is the very end of the run. Check out Thursday, August 27th afternoon. The wind swings around to a glassy NNE at just 3 mph. That's proper offshore for Blacks Beach, which is an exposed spot that loves a WNW swell direction (the guidance says optimum). We'll see a 3ft swell from the SW with a 15-second period, and the combined energy is a moderate 370. The forecast is calling for "expect good surf conditions" – finally. It's a small window, but if you've got the patience to wait it out, that Thursday arvo is your best bet. The rest of the time is a write-off, so save your energy for that one session.

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.
