The Lowdown
Alright, Rusty here. Let's talk about what's on the cards for the next couple of weeks.
Honestly, looking at the forecast, it's a pretty bleak stretch ahead. We've got a long run of small, weak swell and mostly marginal conditions, so don't be expecting any fireworks. The water temperature is sitting at 74°, which is a solid 6° warmer than usual for this time of year – that's very unusual, so you can leave the thick wetsuit at home.
The standout spot, as always, is Blacks Beach. It's an advanced, exposed spot that needs a solid WNW swell, and unfortunately, we're just not getting that. The best window looks like it might be around Tuesday, the 27th of August, into Wednesday, the 28th of August. We're looking at a bit of a bump in swell height, with around 5 ft from the SSW on the 27th morning, and periods around 12 seconds. The combined energy (839) is moderate, but the wind is light and cross-onshore, so it won't be clean. This is really only for the experts, and the conditions are still marginal.
The 14th of August offers a tiny 2 ft SSW groundswell with a very long 18-second period, and light offshore winds in the morning. The energy is weak (547). While the wind is clean, the swell is just too small to get excited about.
For the rest of the period, we're looking at days on end of poor surf. From the 15th through to the 26th, the swell stays under 4 ft, with weak energy values mostly in the 200s and 300s, and the wind is often onshore or cross-onshore, chopping things up. The best of it is still just "marginal" – a lot of days with that "questionable tide" feel.
The 29th of August sees a bit more size, with 4 ft from the SW, but a moderate cross-shore wind from the SSW at 12 mph will kill the quality. It's a messy one.
So, if you're desperate, keep an eye on that 27th and 28th window for the biggest, albeit still average, surf. But honestly, this is a time to take a break or do a dawn patrol with low expectations.
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.
