The Lowdown

Alright folks, Rusty here. Let's have a proper look at what's coming our way. It's a bit of a quiet spell to start, so don't be in a rush.

Alright, so the first real glimmer of something worth paddling out for shows up on Friday the 11th of September. We've got a moderate sized, long period groundswell pushing in from the southwest. The morning at Blacks Beach will see chest to head high sets around `3 ft` from the SW, with that lovely long 16-second period. The water is a balmy `72°F`, which is a good few degrees warmer than usual for this time of year – that’s a real bonus when you’re sitting out there. The main issue here is the cross-shore wind, blowing at `12 mph` from the south-southwest. It’s going to put a bit of a chop on the face. We're looking at moderate wave energy here (530) so there’s some push to the waves, but honestly, the conditions just aren't clean enough to make it a standout. It's a bit of a tease. The afternoon drops off in size and quality, so the morning window is your only shot.

After that, we hit a proper dry spell. From Saturday the 12th through to Wednesday the 17th of September, it’s pretty grim. The swell stays small, under `4 ft`, and often gets tangled up with cross-onshore winds. The wave state comments tell me it’s mostly poor, choppy and not worth your time. You’ll see the energy figures drop right down, barely breaking 400 at times. It’s a real lull and not the time to be chasing waves at Blacks.

The pulse of energy starts to build again on Thursday the 18th of September but conditions are still messy. The real standout, the one to circle on your calendar, is the window from the morning of Saturday the 19th of September right through until Monday the 22nd of September. This is where it all comes together. On Saturday morning, we see the swell bumping up to `3 ft` from the SW with a solid 18-second period. The wind flips to a light `6 mph` from the west, going straight offshore. That’s the magic combo. The water is still warm, and the wave energy is strong at 550. It's going to be glassy, clean and lined up. We are still looking at moderate sized waves, so it’s good for a wide range of ability. This is about as good as it gets in this forecast run.

Sunday the 20th of September is almost a carbon copy with a bigger pulse of energy (677) and light offshore winds from the southwest. The swell is a touch bigger at `3 ft`, still from the SW with that lovely 18-second period. Expect long, clean lines. The energy stays high through Monday the 21st as well, with the wind holding cross-shore from the south-southwest and the swell at a solid `3 ft` from the SW.

After that strong spell, the energy starts to fade. The week starting Tuesday the 23rd of September sees the swell dip back under `3 ft`, the periods shorten, and the wind starts to get messy again. By Saturday the 26th of September, we’re back to small, choppy conditions with a moderate cross-onshore breeze, so the run of good surf is well and truly over.

So, to sum it up: the first week is a write-off with only a very brief, marginal window on the morning of Friday the 11th. Keep your eyes firmly on the weekend of the 19th to the 22nd of September. That’s the clear winner. Offshore winds and long-period SW groundswell at Blacks Beach. It’s a must-surf window, no doubt about it.

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.
