Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright, Rusty here. Let’s get into it.
Right off the bat, I gotta be straight with you – this 16-day window for Blacks Beach is a tough one. For a spot that’s usually a solid performer, we’re looking at a long, long stretch of nothing special. The data shows a gap of nearly two weeks before we even get a whisper of something surfable, and even then, it’s marginal.
The first real sniff of anything approachable doesn’t show up until Thursday, July 17th, in the morning. We’re talking about a small, clean-looking pulse from the SW with a very long period of 19 seconds, but the combined energy is weak, only 253. The wind is light offshore from the WSW, so the surface will be glassy. The swell is only 2 ft though, so it’s a day for the longboard or a big fish. It’s barely a highlight, but it’s the best we’ve got.
The rest of the run is a write-off, honestly. From now until that Thursday, it’s a mix of poor surf conditions, messy cross-onshore winds, and small, choppy waves. The energy readings are all in the low to mid hundreds, with the worst being a paltry 91 on the morning of Sunday, July 19th. That’s barely a ripple.
Even the bigger swells that show up on the 15th and 16th are under 4 ft and get ruined by cross-onshore winds. The period is all over the place – short choppy stuff and long-period groundswells that are just too small to do anything with. For a beach break like Blacks, that long-period energy without size just makes for weird, straight waves.
So, the honest truth? There’s no standout days here. The closest we get is that Thursday, July 17th morning, and even then it’s a session for the patient soul with a log. The water temp is about average for this time of year, so no nasty surprises there. But if you’re hoping for a good paddle, I’d look elsewhere or wait for the next forecast cycle.

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.
