The Lowdown
Alright folks, Rusty here. Let's have a look at what Blacks Beach has in store for us over the next couple of weeks.
Right off the bat, I gotta be straight with you – it's a tough stretch. We've got a whole lot of days where the surf is just not happening, and the wind is messy. The first real chance to even think about getting wet doesn't come until Monday the 14th, and even then it's a bit of a struggle.
We kick off Saturday the 12th with some small 2ft SW swell, but the wind is onshore from the W at 6 mph, and the wave energy is weak (232). The water is a very unusual 74°, which is much warmer than normal for this time of year. Still, with "poor surf conditions" flagged, it's not worth paddling out. Sunday the 13th is more of the same – tiny, choppy, and cross-onshore. A real let-down.
Monday the 14th morning sees a bit more size at 4ft from the W, but the period is a short 8 seconds and the wind is a moderate 12 mph cross-onshore from the SSW. The combined energy is moderate (382), but that wind will make it a bumpy, choppy mess. The afternoon drops back down to 2ft. Not a good look. Tuesday the 15th is still small and choppy, though the afternoon session edges into "marginal" territory with a light breeze, but still cross-onshore. You might get a couple if you're desperate.
Wednesday the 16th morning offers the first glimmer of hope. The wind goes light and onshore from the WSW at 6 mph, with a 3ft SSW swell at a long 17-second period. The energy is moderate (494), and the wind state is unknown but could be glassy. This is the first real chance for a clean wave, but it's small. It's a "marginal" call. For the next several days after that, it's a desert of poor surf with onshore or cross-onshore winds. Thursday the 17th through Tuesday the 22nd are all "poor surf conditions" with only a couple of "marginal" windows. The swell hovers around 2ft to 3ft, but the wind is just never your friend.
The one true standout in this entire 16-day window is the period from Sunday the 20th through Tuesday the 22nd. The wind is still cross-onshore, but light at 6 to 9 mph, and the swell holds steady at 3ft to 3ft from the SW with a decent 16 to 17-second period. The combined wave energy climbs into the strong range, hitting 637 on Monday the 21st morning. This is the best we've got. The sets will have some push, and with a light breeze, it'll be cleaner than anything else on offer. It's still not perfect, but it's the only time we get a consistent pulse of energy with manageable wind.
After that, it fades again. Wednesday the 23rd through Saturday the 26th drops back to poor conditions with 2ft to 3ft swell and light onshore wind. The window closes with a slight uptick on Sunday the 27th, with a 3ft SW swell and 15-second period, but the wind is still onshore from the WNW at 9 mph. It's another marginal call, but too far out to bank on.
So, bottom line: this is a lean spell. Don't get your hopes up for anything epic. The best bet is the Sunday the 20th to Tuesday the 22nd window for the most consistent energy and the cleanest conditions we'll see. It's not a classic Blacks day, but it's the pick of a pretty average bunch.
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.
