The Lowdown
Righto, grab a coffee and settle in. Let's have a look at what's coming down the line here for Blacks Beach.
Alright, the next 16 days are a bit of a mixed bag, to be honest. There's some proper potential in the middle of the first week, but we've got a fair bit of chop and messy conditions to sit through first. The water is running at 72°, which is *much warmer than normal* for this time of year – a real treat.
We kick things off on Sunday the 6th with a messy, lumpy 3 ft SSW swell. Wind is howling out of the north at 19 mph, so it's choppy. A session to skip.
Monday the 7th pushes through some bigger but junky energy. We get a 6 ft SSW swell, but that cross-onshore wind keeps it bumpy and frustrating.
Tuesday the 8th is more of the same, just smaller at 4 ft and still not clean.
Now, here's the one to get excited about. Wednesday the 9th is where it's at. The swell drops to 2 ft to 3 ft from the SSW, but the real story is the wind. We’ve got glassy conditions – a light NNW swinging WSW. For a break like this exposed to WNW, that's as clean as it gets. This is your standout. The energy is moderate (448-517) but with that long 16-second period groundswell, those small waves will have serious push and shape. It’s consistent here at Blacks Beach, so you'll get plenty of rides, and it's an advanced wave, so it'll be a fun, clean playground.
Thursday the 10th through to Saturday the 12th gets a bit grim again. Swell bumps up and down, but that cross and cross-onshore wind messes it all up. The combined energy gets weak (255-314) by the weekend. Just not worth the drive.
Sunday the 13th to Tuesday the 15th is a write-off. The swell drops away, period goes short and mushy, and winds are no good. Small, weak, and choppy.
There's a glimmer of hope mid-to-late in the second week. Wednesday the 16th sees a 3 ft SSW groundswell with a long 17-second period and light cross-onshore winds. The energy is moderate (623). It's marginal, but a whisper of quality. Keep an eye on that.
Thursday the 17th to Sunday the 21st is mostly onshore and messy. The swell bumps up to 3 ft to 4 ft from the SW with some very long 19-second periods by the 20th and 21st, which sounds good on paper – energy jumps up to a solid moderate (757-802) – but that onshore wind is going to flatten it out and make it choppy. Not a strong recommendation.
So, to wrap it up: don't bother this weekend. The real session is Wednesday the 9th. Get on it. The second week has some longer-period energy but the winds just aren't cooperating. That's the gamble of a longer-range look.

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.
