The Lowdown
Alright folks, ol' Rusty here with the long-range look for the only break that's got any data worth chewin' on: Blacks Beach.
Straight up, this is a tough one. We're lookin' at a sixteen-day window that starts off real flat and messy. The first solid sniff of anything surfable comes on Thursday, July 23rd in the afternoon. That's a gap of nearly a week and a half of nothin' worthwhile. The rest of the run is plagued by cross-onshore breezes that'll chop up whatever small swell tries to push in. The water temps are about 6°F warmer than usual, which is weirdly tropical for this stretch of coast.
The only real standout in the whole period is that Thursday afternoon. We've got a tiny 2ft swell from the SSW, but the wind goes glassy. That's a beautiful thing. The energy is weak (169), but with clean conditions, even a dribbler can be fun on the high tide. The swell period is 13 seconds, which is a decent groundswell, but it's small.
Blacks is a consistent, exposed spot, and it's often crowded. For a wave that's mostly for advanced crew, the crowds are somethin' you'll have to deal with if you want a piece of that glassy window.
The rest of the period is a write-off for quality surfing. The swell tries to pick up, especially around Saturday, July 25th afternoon, when a 8ft SSW swell shows up with a massive 2237 energy reading. But it's cross-onshore, choppy, and that size is in the "experts only" zone. The conditions are too poor for the average punter.
Forget the first week. Don't even bother. Just keep your eye on that Thursday afternoon glass-off. If you're a salty local, that's your one shot.

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.
