The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

Honestly, it’s a pretty quiet run overall. The surf’s gonna be on the small side for most of the period, and the wind’s not always gonna play nice. We’ve got a few moments that could be worth a paddle, but you’ll need to pick your windows carefully.

The first real chance to get wet is this Saturday, the 5th of September. Early on, we’ve got a 3 ft swell from the SSW with a really long 16-second period, so there’s proper groundswell energy in the water (combined energy of 578). The wind is a light cross-onshore from the WNW at 6 mph, so it’ll be a bit bumpy but not blown out. The water’s about average for this time of year. Blacks Beach is an exposed spot, so it’ll pick up what’s out there, but the tide might mess with the shape a bit. That long period can make it wall up at a beach break, so it might be better for the more experienced crew. There’s a chance of crowds, so keep your eyes open.

Saturday afternoon sees a similar tiny bump to 4 ft from the SW with the same long period (628 combined energy), but the wind picks up to 9 mph and goes directly onshore. That’s gonna make it messy.

Sunday the 6th is a write-off. The swell drops right off to 1.0 ft with a short 10-second period, and we’ve got a moderate 16 mph cross-onshore. Choppy junk. Skip it.

Monday the 7th is where things get a bit more interesting. We’ve got a 6 ft SSW swell pulsing in with a 13-second period – that’s solid, proper size. The combined energy is cranking at 1182. But the wind is a cross-onshore again at 9 mph, so it’s gonna be pretty choppy. This is definitely in the "experts only" zone size-wise, not for the beginners. The quality is marginal, but if you’re hungry for size, that’s your window.

Tuesday the 8th drops back a touch to 5 ft, and the wind’s still cross-onshore. The wave energy is still moderate (986), but the conditions are poor. It’s just not clean.

From Wednesday the 9th all the way through to the end of the second week, the swell stays tiny – mostly under 3 ft and often around 1 ft to 2 ft. The wind is light and variable, sometimes cross-onshore, sometimes offshore. The period is long, but with that little height, it’s gonna be a struggle to find anything worth paddling for. The combined energy values are mostly in the 200s and 300s, which is weak.

There’s a little blip on Saturday the 19th of September, with a 5 ft swell from the west and a shorter 10-second period, and light offshore winds from the WSW. The combined energy is 861 – moderate. That morning might be the best of the whole run if it holds together, but it’s a long way out, so don’t lock it in just yet.

The long-range stuff from the 14th through the 20th is all small and marginal. The 18th of September has a 2 ft swell with a 20-second period, which is an incredibly long groundswell, but with that little height, it’s just a gentle bump. The energy is in the 500s, so it’s there, but it’s not a standout.

Bottom line: If you’re desperate, Saturday the 5th and Monday the 7th are your best bets for the first week. The second week is a bit of a gamble, with the 19th of September looking like the most promising of a quiet bunch. Keep an eye on the forecasts, but don’t expect fireworks.

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.
