The Lowdown
Alright, let’s have a look at what’s on offer. To be honest, the next couple of weeks are looking pretty flat and frustrating. The water is running at 76°F and that's much warmer than normal for this time of year – a real standout, but it almost feels like a tease because the surf just isn’t there to enjoy it.
The whole 16-day window is a tough one. There’s a long dry spell right through the first week and into the second. From Monday, August 3rd all the way through to Thursday, August 14th, it’s just poor surf conditions day after day. The swell is tiny, mostly around 2 ft to 3 ft, and the wind is consistently cross-on or onshore, keeping things crumbly and uninviting. The energy is weak to moderate at best, with readings like 129, 166, 170 – nothing that gets the heart pumping.
Now, there’s a glimmer right at the very end. On Saturday, August 15th, we finally see a bump. The morning session at Blacks Beach (San Diego) shows a 3 ft SSW swell, with a period of 16 seconds – that’s proper groundswell energy. The combined energy reads 524, which is finally getting into the moderate range. The wind is offshore from the W, so it’s going to be clean. The swell direction is SSW, which is a touch off the optimum WNW for this spot, but it’s still rideable. This is the best on offer, though it’s only a marginal forecast – so don’t get too hyped. The afternoon pushes up to 3 ft with the same SSW direction and 571 energy, but the wind swings more WNW, still offshore, so it should hold up. Crowds are likely here at Blacks, so expect some company.
On Sunday, August 16th, the swell drops back to 3 ft, and the wind stays offshore from the WNW, so it’s still clean but smaller. The energy is 467 – still respectable. The following Monday, August 17th sees a shift to a W windswell, but with a period of only 7 seconds, it’s going to be short and bumpy, and the cross-on wind won’t help. The combined energy jumps to 395, but energy without quality is just messy.
Overall, if you’re desperate, Saturday, August 15th is your only real shot. Otherwise, it’s a long wait. The forecasts can change, but as it stands, this is a tough stretch for Blacks Beach.

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.
