The Lowdown
Alright, folks, Rusty here. Let’s have a look at what we’ve got on the cards for the next couple of weeks. I gotta be straight with you from the jump: it’s a pretty grim stretch ahead for Blacks Beach. There’s nothing that’s going to get the heart racing for a while, so if you’re jonesing for a wave, you might want to find something else to do.
For Blacks Beach, the water is sitting at 72°F which is much warmer than normal for this time of year. That’s over three degrees above average, so it’s like stepping into a bath.
The first few days are basically a write-off. Sunday the 6th is a total dud: small, weak swell coming from the NW at only 2ft with a pathetic 4-second period, the wind is a messy cross-onshore, and the combined energy is just a measly 46 – that’s barely a ripple. It’s a big fat zero. The afternoon doesn't get any better – the wind picks up to 22 mph and it’s a cross-shore mess.
Monday the 7th morning shows a bit of size, with the swell bumping up to 6ft from the SSW. That sounds promising, but it’s got a cross-onshore wind that's going to chop it up. The energy is strong, at 1237, but with the wind, it’s only marginal at best and the score reflects that. It’s just not clean.
The rest of the first week and into the second is a long, drawn-out story of small to moderate swell (2ft to 5ft) and almost always with a cross-onshore wind. The wind just won’t let up, keeping things choppy and uninviting. There are a few moments, like Wednesday the 9th afternoon and the following Monday, where we see some light offshore winds, but the swell is tiny (2ft to 3ft). The energy values hang around in the mid-hundreds, which is moderate, but without any decent size or clean conditions, it’s nothing to write home about.
The standout, if you can call it that, is the morning of Monday the 7th. It’s the biggest swell of the whole run at 6ft from the SSW, with a solid 13-second period. That’s a groundswell with some push, and the energy is high at 1237. But the wind is cross-onshore from the WNW, which will mess up the face. For a break like Blacks, which is exposed and works best with clean conditions, this is a real letdown. If you’re an advanced surfer and you don’t mind some chop, you might find a few, but it’s not going to be a classic session.
From about Wednesday the 9th onward, it’s a long, slow grind. The swell direction shifts to the SW, the periods get longer (up to 20 seconds), but the size stays small. The wind is mostly light and often offshore, which is a big positive – it will be glassy clean. But the waves just aren't there. The energy stays moderate, and the scores are all at the bottom end. It’s a classic case of “clean but tiny.”
For a spot like Blacks, which is a beach break and can handle some size, this run of small swell with poor winds is pretty disappointing. There’s no real standout session where everything lines up. The best you can hope for is a glassy morning on the tiny days, but you’ll be fighting for scraps.
So, the outlook is pretty bleak. There are no good surf options in this 16-day window. It’s a long blank run, and with the consistency not being there, this is a bit more normal for the area when the conditions don’t align. Forecasts can change, but right now, I’d say hang up the board for a bit.
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.
