The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s cookin' over the next couple of weeks. Straight up, I gotta be honest with ya – it’s a lean stretch. We’re starting with a whole lot of nothin’ for the first week and a half. The first real glimmer of anything worth paddling out for doesn’t show up until Friday the 14th of August, and even then, it’s marginal. So, if you’re itchin’ for a wave, you’re gonna be waitin’ a while.
The only break on the radar is Blacks Beach. Right now, the water is a balmy 76°, which is a solid 9° warmer than usual for this time of year – that’s a real rarity, feels like a tropical bath.
From Tuesday the 4th right through to Thursday the 13th of August, it’s a desert. The swell is tiny, mostly around 2 ft to 3 ft, and the wind is a dirty cross-on or onshore from the WSW or SW. The wave energy is all over the shop, from a weak 119 (moderate energy) up to a decent 470 (strong energy), but it doesn’t matter because the conditions are just poor. The wind is choppin’ it up something fierce. You’d be better off stayin’ home and waxin’ your board.
Now, we finally get a little pulse of life on Friday the 14th. The swell bumps up a touch, and the wind shifts to a clean onshore from the W and WSW. In the morning, we’re lookin’ at 2 ft of SSW swell at a long 18 seconds, and the combined energy jumps to 523 (strong energy). The afternoon sees the swell hit 3 ft, same direction, 18 seconds, and the energy climbs to 720 (strong energy). The forecast calls it “marginal” – and for me, that’s the best of the whole run. This is a long-period groundswell, which means proper shape and power, but it can be a bit straight at a beach break like Blacks. Still, with that offshore wind, it’s the cleanest we’ll see.
Saturday the 15th is the other day that might be worth a look. The morning has 4 ft of SSW swell, again at 16 seconds, with light WSW winds. The energy is a solid 727 (strong energy). That’s the biggest swell of the entire forecast. It’s getting up there, so if you’re a beginner, this might be a bit much – it’s pushin’ into expert territory. The afternoon backs off a little but stays clean.
For the rest of the run after that, the swell fades back into the 2 ft to 3 ft range and the wind swings back to being mostly onshore, so the quality drops off again.
So, to wrap it up: if you’re desperate, Friday the 14th of August is your best bet, with the morning seeing the cleanest conditions on offer. Saturday the 15th has the most size, but it’s a bit rougher. Other than that, it’s a long, dry spell. But hey, it tends not to stay this flat for long around here, so keep an eye on the charts.
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.
