The Lowdown
Alright, Rusty here. Let’s talk about what’s happening in the water over the next couple of weeks.
Straight up, it’s a frustrating stretch for Blacks Beach. The ocean is putting a lot of energy into the water, but the conditions are just not lining up for a proper paddle session. We’ve got some solid long-period groundswell rolling in, but it’s coming from the SSW, which is not the optimum direction for this spot. That means the waves are wrapping in but not holding their shape well, and the wind is almost always cross-onshore, messing with the surface.
The standout period is actually the very start, on Monday the 27th of July. Sure, the waves are only 4ft, but the swell period is a very long 18 to 19 seconds, which is a proper groundswell. The water temp is a wild 75°, which is a massive 7° warmer than usual for this time of year – that’s freakishly warm, you’ll feel like you’re in the tropics. The combined energy is pumping at 1127 (moderate to strong), but here’s the kicker: the wind is a light 6 mph cross-on, and the forecast says "questionable tide conditions." It’s marginal, but that’s the best we’ve got. For a high-level break like this, it’s more of a fallback than a standout.
After Monday, it’s a downhill slide. Tuesday the 28th sees the swell holding at 5ft with a 17-second period, but the wind picks up to 9 mph from the SW, making it choppy. The energy drops to 983 (moderate), and it’s still cross-onshore. By Wednesday, the swell is fading to 4ft, and the energy is down to 660. The conditions are just plain marginal.
Then we hit a huge gap. From Thursday the 30th of July all the way through to Sunday the 9th of August, there’s nothing worth paddling out for. The swell drops to tiny 1.0ft to 2ft, the period is all over the place, and the wave energy is weak (80 to 289). The wind is either onshore or light cross-on, but the waves are just pathetic. That’s a solid 10-day stretch of flat or poor surf.
The only flicker of life comes on Friday the 7th of August. The swell picks up to 3ft with a 18-second period, and the energy is back up to 502 (moderate). The wind is light from the WSW, but it’s still cross-onshore. The forecast says "marginal," so it’s not game on. Saturday the 8th and Sunday the 9th are similar, with 3ft and 4ft swell, but the wind is still a problem. For a spot as exposed as Blacks Beach, the constant cross-onshore wind is the killer.
Honestly, this is a tough read. The ocean is putting in the energy, but the wind and direction are just not with us. If you’re desperate, Monday the 27th is your best bet, but don’t expect magic. This is a stretch where the setup looks more interesting for kite surfing than paddle surfing, given the consistent cross-shore wind and moderate swell.

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.
