Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright folks, Rusty here with a look at the upcoming stretch. Gotta be straight with you – this is a challenging 16-day window. We’ve got a long period of rough conditions before a very short window of hope.
We’re starting off with a bit of a flat spell, and the first few days aren't looking great at all. The good stuff is really a long ways off, so patience is key.
Blacks Beach is the only spot on the menu here, and for the first week, it’s a grind. From Tuesday, 7 July, right through to Sunday, 12 July, we’ve got a whole lot of nothing to get excited about. The swell is small, mostly around 3 ft to 3 ft from the SSW, but the problem is the wind. It’s just constantly cross or cross-onshore, making everything choppy and bumpy. The energy readings are dropping through the week from a moderate 852 all the way down to a weak 216, so there’s just no push. It’s poor to marginal at best.
We do get a brief tease on the morning of Monday, 13 July. The wind goes completely glassy and we’ve got 3 ft of SSW swell, but the period is surprisingly long at 13 seconds. That’s proper long-period energy from a groundswell, which means better shape but long waits between sets. The combined energy is a weak 346 though, so don’t expect waves with much punch. It’s a true window of clean, glassy surf, but it’s going to be inconsistent and small. For the advanced crew who love a challenge, this is your only real standout, but dial those expectations right down.
After that morning, it’s back to the doldrums. From Monday afternoon, 13 July, all the way through to Wednesday morning, 22 July, the forecast is a desert. We see the swell trying to build a little on the 21st, hitting 4 ft from the SSW with 681 in the energy department, but the wind is cross-onshore again, trashing any chance of a quality wave. It’s a long, long wait.
So for this whole 16-day stretch, the absolute best on offer is that Monday morning session at Blacks. Expect a clean, glassy surface, tiny but long-period groundswell, and no crowds if you’re out there at dawn. Keep an eye on the models, though – this long flat spell can’t last forever.
Stay patient,
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.
