The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up.
Honestly, the next couple of weeks are a real mixed bag, and it’s a bit of a slow start. The first proper surf window doesn’t really open up until we get into the second week. For the first ten days or so, the wave energy is just too weak and the conditions are too messy to get excited about. We’re looking at a long stretch of "poor surf conditions" with onshore or cross-onshore winds and very small swell. That’s a big gap to sit through, from the start of the period all the way to around the 14th of August.
The standout moment – and the only real highlight I’d paddle out for – is shaping up on the morning of Friday, 14th August at Blacks Beach. It’s not going to be huge, but it’s the first time we get a sniff of something decent. We’ll see a 3ft swell from the SSW with a long period of 19 seconds, which is proper groundswell energy. The combined energy of all swells directed here will be a solid 584 (moderate wave energy), and the wind will be light and offshore from the W, keeping things clean. That long period groundswell is best held together on a point break or reef, but Blacks can handle it – just be aware that the sets might be a bit spread out with that long period. The water temp is a warm 76°, which is much warmer than usual for this time of year, so you won’t need a thick wetsuit.
The Saturday the 15th of August is also worth a look, with a 3ft swell from the SSW and similar offshore winds, though the period drops to 16 seconds. The energy is still moderate (602) and the wind is favourable, but it’s a touch smaller and shorter period than the Friday. Still, if you miss the Friday, Saturday morning is a solid second option.
Beyond that, into the following week, it tails off again. The swell drops back to 2ft to 3ft with poor conditions. So, if you’re keen, your best bet is to pencil in that Friday the 14th or Saturday the 15th.
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.
