Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright crew, Rusty here. Let’s break down this stretch of coast.
To be honest, this is a rough patch. There's a big gap of time with no real surf on offer. The first half-decent look doesn’t roll in until the morning of Sunday, July 12th, and even then it’s just barely worth a mention. Before that, it’s all poor conditions with dirty cross-onshore winds and weak energy.
Blacks Beach is the only break we’re looking at. The water temp is 72°, which is much warmer than normal for this time of year – a real standout at 3° above the average. Weird.
On that Sunday morning, the 12th, there’s a small 3ft swell out of the SSW with a 14-second period. The combined energy is weak at 323. Winds are light cross-onshore, so it’s not a total mess, but it’s marginal. This is a consistent spot for advanced surfers, so if you’re confident, you might scratch into a few. But don't expect much.
We then drift through a string of days with poor surf and onshore winds. The next tiny flicker is Monday morning, the 13th – same story: 3ft from the SSW, 13-second period, 336 energy. Still marginal. After that, it’s back to poor conditions until Wednesday morning, the 15th. That morning shows a 3ft swell from the WNW with a short 8-second period. That’s weak, short-period energy with a cross-on wind. Not a winner.
Thursday the 16th morning has a slight bump to 4ft from the W, but still an 8-second period and cross-on wind. The energy is moderate at 338, but the quality is poor.
The second week is a blur of poor and marginal calls. The 21st of July (Tuesday) is the closest we get to a decent window: a 3ft SSW swell with a nice 16-second period and light cross-on wind. The energy is moderate at 542. The longer period helps shape, but at a beach break, it can straighten out a bit. Still, with light winds and that groundswell, it’s the best option in a flat run.
No epic days here, folks. No big swell, no clean barrels. Just a few small, hopeful windows for the die-hards. Keep watching – it never stays this quiet for long.
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.
