The Lowdown

Alright, this is Rusty, and I’m looking at the next couple of weeks for us. Let’s get straight into it.

Alright, so we’ve got a bit of a mixed bag shaping up. The main event is a solid SSW groundswell that rolls in early next week, but the wind is going to be a bit of a headache. The water is surprisingly warm for this time of year, running about 74°, which is a solid 6° warmer than usual – that’s very unusual, feels like a late summer holdover.

The first real window of opportunity looks like Friday, September 4th afternoon. We’re seeing a clean 4ft SSW swell with a long 16-second period at Blacks Beach. The wind is a light offshore from the WNW at 9 mph, which is a solid vote for clean conditions. The combined energy is moderate at 781, and that offshore flow should keep it nice and lined up. It’s a little on the smaller side, but it’s a good start.

Saturday, September 5th morning is even better. The swell drops slightly to 3ft, but the wind is even lighter at 6 mph from the WNW, still offshore. That’s going to be glassy and clean. The energy is a bit lower at 605, but for a Saturday morning paddle, you could do a lot worse. Afternoon sees the wind shift a touch cross-on, so morning is the move.

Now, the standout. Sunday, September 6th morning brings a jump in size. We’re looking at 7ft of SSW swell, but the period drops to 14 seconds, so it’s a bit more powerful. The energy hits 1748, which is solid. The catch is a moderate cross-shore wind from the NNW at 12 mph, which will put a bit of a chop on the face. That’s expert territory at 7ft and a bit bumpy, so only for the experienced crew. It’s the biggest day of the window, but the wind keeps it from being perfect.

Monday, September 7th keeps the size at 7ft, but the wind is a lighter cross-on from the WNW. The energy is still high at 1640. It’s still a big, powerful swell, but that cross-on breeze will make it a bit of a battle. Again, for experts only.

After that, things wind down. From Tuesday, September 8th through to about Thursday, September 17th, we’re looking at a long stretch of small, weak surf – mostly under 3ft with poor conditions. The energy drops right off, often below 500. The wind stays messy or too light to do much good. There’s a solid 9-day gap where you’re better off doing something else.

We do get a little bump back towards the end of the window. Friday, September 18th and Saturday, September 19th see a small, long-period SW swell (20 and 18 seconds) pushing back in, with light offshore winds. Swell heights are only 2ft to 3ft, but with that long period and clean wind, it could be a fun little glassy session for a log or a fish. The energy is moderate, around 680 to 736. It’s a promising note to end on, but it’s a long way out, so keep an eye on it.

Bottom line: The best bet is Saturday morning, September 5th for the cleanest conditions on a manageable swell. If you’re an expert, Sunday morning, September 6th has the most power, but expect some chop.

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.
