Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Right then, let’s have a look at this 16-day window. To be straight with you, it’s a pretty grim run for Blacks Beach. The whole forecast period is a write-off as far as decent surf goes. We’re looking at a solid two and a half weeks of nothing worth paddling out for, so if you’re hanging for a wave, you’re better off finding something else to do for a while.
The first day with any surf on offer is Friday the 10th of July, but it’s a real dud. We’ve got a 3ft swell from the SSW with a period of 15 seconds, which is a long-period groundswell. Combined energy is moderate at 498, but the wind is a cross-onshore 9 mph from the SSW, chopping it up. The water temperature is a very unusual 72°, which is a huge 6° warmer than normal for this time of year, so it’s like swimming in a warm bath, but the waves are a complete mess. It’s poor surf, and that sets the tone for the whole outlook.
The forecast just never gets going. Saturday the 11th stays poor with the same sort of weak, cross-onshore junk. Towards Sunday the 12th and Monday the 13th, the wind goes light onshore, but the swell drops to 3ft-3ft and the energy is weak (216 to 336). The surf is still no good. By Tuesday the 14th, we see a 2ft swell with a long 18-second period from the SW, but the energy is weak (265) and the wind is onshore, so it’s a dud again.
The pattern continues right through the second week. From Wednesday the 15th of July all the way to Saturday the 25th of July, it’s a parade of poor surf conditions. The swell stays tiny, mostly between 1ft and 3ft, with weak to moderate energy (92 to 549). The wind is almost always cross-onshore or onshore, even when it’s light. There’s a slight glimmer on Sunday the 19th of July when the swell hits 3ft from the SW with a 17-second period and energy of 519, but the wind is onshore from the W, so it’s still marginal at best. The comment says “marginal surf forecast or questionable tide conditions,” which is about as good as it gets, and that’s not saying much.
The very end of the outlook, on Saturday the 25th of July, sees a 2ft swell from the west with a short 8-second period and only 92 energy. That’s pitiful.
So, the bottom line: there are no standout sessions, no hidden gems, no reason to get excited. The only break on offer, Blacks Beach, is a consistent, exposed spot, but with this forecast, it’s just flat, windy, and messy. Honestly, if the wind keeps up from the SW like this, the setup at Blacks Beach looks more interesting for kite surfing than paddle surfing. It’s a blank run, and for this area, that’s not unusual given the forecasts we’re looking at. Keep your eye on it, though – it tends not to stay this poor for long, and things can change. But for now, it’s a hard pass.

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.
