Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright, Rusty here. Let's be straight with you – this is a rough patch for Blacks Beach. We're looking at a long stretch of small, messy, and often onshore conditions. It's going to be a real test of patience.
The water's sitting at 71°F, which is much warmer than normal for this time of year, so at least the wait will be comfortable.
The first few days, starting Thursday the 9th, are a write-off. We've got a small 3ft swell from the SSW, but it's a 16-second groundswell, which is a long period, and with a cross-on wind, it's just choppy and weak. The combined swell energy is 731 (moderate), but the wind wrecks it. We don't get a clean window until Sunday the 12th. The wind finally swings offshore from the WSW, light at 6 mph, and the swell drops to 3ft, still from the SSW, with a period of 14 seconds. The energy is down to 324 and it's marginal, but that offshore wind is a major positive. It's the best we'll see for a while, but it's still small.
Monday the 13th is similar – a light offshore and a 3ft SSW swell, but the energy is still weak at 338. It's a paddle-out, but you won't be doing much.
Then we hit a dry spell. From Tuesday the 14th right through to the end of the forecast on the 24th, it's a real grind. The swell stays tiny, mostly under 3ft, and the wind is often onshore or cross-on. There's a moment on the 14th afternoon with a 2ft, 18-second SW swell, but it's cross-on. The 19th has a morning with 3ft and 513 energy, but again, cross-on wind. There's just nothing to get excited about.
For a spot that's exposed and consistent, this is a poor run. The best bet is to look for the cleanest windows of light offshore wind, which are Sunday the 12th and Monday the 13th, but even then, it's a marginal, small-wave day. It's not for beginners, but it's not big enough for the experts either. This is a wait-and-see period.
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.
