The Lowdown
G’day, it’s Rusty here. Well, lookin’ at the whole 16-day window, there’s not a whole lot to get excited about, to be honest. We’ve got a long, drawn-out run of mostly small, marginal conditions, with only a couple of brief windows that might get the heart beatin’ a little faster. Let’s step through it.
The first surf that’s even worth a mention is Friday, August 28th, but it’s a real soft start. Blacks Beach is the only spot on the cards. We’re lookin’ at a long-period groundswell (16 seconds) from the SW, but it’s tiny – only 2ft to 3ft. The wave energy is weak (359) in the morning, then it jumps to moderate (583) by the afternoon when the swell direction shifts a touch more to the SSW. The wind is light offshore from the W, so it’ll be glassy and clean. But honestly, it’s marginal, with questionable tide conditions. The water is a whopping 76°F, and that’s 7°F warmer than usual for this time of year – very unusual, you’ll feel like you’re in a tropical bath.
Saturday the 29th sees a slight bump, with the swell hittin’ 4ft to 4ft from the SSW, still with that long period (15-16 seconds) and a moderate wave energy (730 to 952). The wind stays offshore, comin’ from the W and WNW, so it’s clean. The swell is still small, though, and the surf quality is still judged as borderline. It’s not a standout, but it’s the best we’ve got in the first week.
Then from Sunday the 30th right through to Wednesday, September 10th, it’s a real flat spell. The swell drops back to 2ft to 4ft, the period drops, and the wave energy is mostly weak. The wind is often offshore, but the punch just isn’t there. The models are callin’ it poor conditions for days on end, with a few marginal sessions mixed in, but nothing that’d make you rush for the wax.
The true standout, if you can call it that, is comin’ on Friday, September 4th. The morning session at Blacks Beach has a 3ft SSW swell with a very long period of 17 seconds, and a moderate wave energy (919). The wind is a light offshore from the W, meanin’ it should be clean. That long period means the waves will have some real shape and power for the size, and the gaps between sets will make paddlin’ out easier. But it’s still a small swell, so it’s a finesse session. The afternoon gets a bit choppy with a cross-onshore breeze. This is the pick of the whole 16 days – a promising, though not certain, highlight.
After that, from the 5th through to the 12th, it’s back to the same old story: small swell, poor or marginal conditions, and a lot of choppy afternoons. The wind is mostly offshore or cross-onshore, but the swell just doesn’t have the size or consistency to get excited about. The wave energy is usually weak to moderate, and the scores are flat.
So, for the crew who just want to get wet, the mornings of the 28th, 29th, and especially the 4th of September are your best bet. The rest of the window is a write-off for anything decent. Don’t hold your breath.
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.
