The Lowdown

Alright folks, Rusty here. Let’s get into it.

First up, we’re looking at a pretty grim stretch ahead. The whole 16-day window is basically a bust for good waves at Blacks Beach. We’ve got swell, sure, but it’s small and weedy, and the wind is just never quite right. There’s a long gap of nothing but poor conditions right from the start, with the first tiny glimmer of something barely surfable not showing up until Friday the 14th.

The real story here is the water. It’s *much warmer than normal* for this time of year, sitting at 76°F with a huge anomaly of 8°F above average. That’s very unusual.

Now, for the surf. The first few days – Tuesday the 11th, Wednesday the 12th, and Thursday the 13th – are all a write-off. You’ve got a tiny 2ft SSW swell, and while the wind is offshore, they’re calling it “poor surf conditions.” The combined energy is weak to moderate (324 – 409). Not worth a paddle.

We finally get to *Friday the 14th* and that’s where the only marginally interesting window opens up. The morning brings a bit more push with a 2ft SSW swell, but the period is a very long 18 seconds. That kind of long-period groundswell can be tricky at a beach break like Blacks, often making it close out or section. The wind is offshore, though, and the energy is finally building into the moderate range (547). The afternoon is similar, with a 3ft SSW swell, same long period, and the energy jumps to 765. It’s still only a “marginal” call, but it’s the best we’ve got.

*Saturday the 15th* is the closest thing to a standout, but that’s not saying much. The morning has a 3ft SSW swell with a 16-second period, clean offshore wind, and combined energy of 620. The afternoon bumps up to 4ft from the SSW, still with that long period, and energy hits 705. Still only “marginal” surf conditions. The waves will be small and the long period makes it suspect for a beach break, but if you’re desperate, the Saturday morning session is your best bet. The wind is offshore, so it’ll be clean, but don’t expect much power.

After Sunday the 16th, it’s back to poor or marginal conditions all the way through to Wednesday the 26th. The swell drops back down to 1ft to 3ft, and the wind is often cross-onshore, making it choppy. The energy fluctuates but never gets truly strong. The last few days, from the 23rd to the 26th, show some slightly better winds but the swell is tiny. There’s a slight uptick on Wednesday the 26th afternoon with a 4ft SW swell and energy at 779, but it’s still just marginal.

Overall, this is a tough spell. The only real “standout” is the Saturday morning surf on the 15th, and that’s a low bar. It’s clean, but small and likely a bit fat with that long period. For the rest of the 16 days, you’re better off doing something else.

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.
