Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright, let's start with the one spot that’s got our attention: Blacks Beach. I won't lie, looking at the whole 16 days, there's a massive hole at the start. From Friday the 10th of July right through to Saturday the 19th of July, it’s just no good. We're seeing small, weak swell, mixed up with onshore or cross-onshore winds, and the wave comment is screaming "poor surf conditions" every time. The combined energy is barely into the moderate range, sitting around 200 to 500 – not enough to get excited about. The water temp is about average for the time of year, nothing weird there.
It's not until the second week that things start to look interesting, but it's a slow build. On Sunday the 19th of July, we get a bit of a lift. The morning's marginal, but by Sunday afternoon we've got a 0.9m swell from the SW, period around 17 seconds, and the wind is a light offshore from the W. The combined energy jumps up to 553, which is solid moderate. It's still only scoring a 2 out of 10, but that's the best we've seen. The onshore wind is keeping it clean enough for a session, but the swell is small.
Then, on the 20th and 21st of July, we get some days with similar potential. Tuesday the 21st looks the pick of the bunch. We're seeing a 1.1m SSW swell with a period of 15 seconds, and a light offshore wind from the W. The combined energy is 579 – the highest in the whole forecast. It’s a marginal call, but with the clean offshore wind and that long-period groundswell, Blacks Beach could offer some nice, lined-up waves for the advanced crew. That’s your standout window: around the 19th to the 21st of July.
Just be aware, the swell direction is SSW, but the optimum for Blacks Beach is WNW. It's not a perfect match, but the combination of that offshore wind and the long-period energy is enough to get a few waves. Also, the crowd situation here is "often", so expect some company, especially if the quality shows up.
After that, it fades again. The 22nd and 23rd drop back down to poor conditions with smaller swell and weaker energy. The very end of the forecast, the 24th and 25th, shows a small shift with a short period W swell, but the winds are cross-on, and it's still looking pretty ordinary.
So, to sum it up: a long dry spell, then a small window around the 20th of July where the long-period groundswell lines up with clean, offshore wind. It's a low-energy setup, so don't expect barrels, but it'll be the only game in town.

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.
