The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Blacks Beach.
Right off the bat, we’ve got a long stretch of nothing good. The next two weeks are looking pretty grim, with a massive gap in any decent surf. The first mention of anything even close to worthwhile doesn’t show up until Friday, August 14th, and even then it’s a real coin toss. That’s over a week and a half of flat, poor conditions to sit through.
The issue is a stubborn pattern of light to gentle breezes that are mostly cross-onshore, ruining the shape of the tiny swell that’s around. The waves are small, under 3ft, and the wind is just enough to mess them up. The combined wave energy is weak to moderate at best, hitting the low hundreds most days (124-230), which is a lot of energy going nowhere good.
For most of the first week, we’re stuck with these 2ft to 2ft SW swells with a period around 13-15 seconds. The wind is either cross-on or onshore, so it’s choppy and messy. Not worth paddling out for.
Finally, on Friday, August 14th, things start to look a little less hopeless. The swell bumps up to 3ft, coming from the SSW with a long period of 18 seconds. The wind switches to light onshore, which is a big upgrade. The combined energy jumps to a strong 582 – that’s the first time we see a solid number. The water temp is a very unusual 76°F, which is much warmer than normal for this time of year. This is the best window on offer, but it’s still only a marginal call.
Saturday, August 15th holds the best bet. The swell picks up to 3ft from the SSW, still with a 16-second period, and the wind is light and onshore. The combined energy is strong (564). This is the standout of the whole 16-day forecast. For an advanced spot like Blacks Beach, a 3ft SSW groundswell with light winds could be clean and fun. It’s not big, but it’s the only time we’ve got a decent combo.
After that, it drops back down to the same old poor conditions again. The long period (over 15 seconds) on these swells means they’ll be better shaped and more powerful, but at a beach break like Blacks, they can also break a bit straight. Given the overall lack of size and quality, this setup might actually be more interesting for kite surfing than a standard paddle session for most of the window.
So, the only window that’s worth your time is the Friday, August 14th to Saturday, August 15th stint. Saturday is the pick. It’s a long way out, so don’t get your hopes up too high, but it’s the only real chance for a wave.
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.
