The Lowdown
Alright, grab your board. Rusty here.
To be straight with you, the next week and a half or so is a slow grind. We’ve got a lot of days where the ocean just isn't cooperating. The first real hopeful window doesn't open up until about Friday, 5th of September, and even then, it's a bit of a tease. Before that, there are long gaps of nothing worth paddling for.
The only spot worth talking about is Blacks Beach. It’s an exposed, advanced break that needs a good WNW swell to really light up, and it's consistent when it gets it. The water temp right now is sitting at 72°F, which is over four degrees warmer than usual for this time of year – feels more like summer holding on.
For the next several days, it's mostly small, wind-affected junk. The swell is there, coming from the SW, but it’s weak. On Sunday the 23rd, we see a 2ft SW swell at a long 18 seconds. That’s a classic, drawn-out groundswell, but the energy reading is low (359) and the wind is onshore. Not a good look. That pattern holds all week – onshore or cross-onshore winds muck up those small, long-period waves. The energy stays in the "moderate" range on Friday the 28th (428-454) with a 3ft swell, but the wind is barely forgiving, giving us "marginal" conditions at best.
The weekend of the 29th-30th picks up a little. Saturday the 29th has a 4ft – 4ft SSW swell, and the combined energy climbs over 700. Still, the wind is either on or cross-on, so it’s not going to be clean. You might find a few, but you'll be working for them. The combined energy on Sunday the 30th (681) is solid, but a moderate cross-shore breeze from the SSW will leave a bit of chop on the surface.
There's a big drop-off early the next week. Monday the 1st of September is flat with a 1ft swell and weak energy. Then a few more days of tiny, marginal junk.
Now, for the standout, you have to wait until Friday, 5th of September. The morning of the 5th sees a 4ft SSW swell, building from the day before (combined energy hits 1007 on the 4th), but the real winner is Saturday morning, 6th of September. That’s the one. The swell holds at a solid 4ft from the SSW, but more importantly, the wind goes light offshore from the NE – that’s clean. The conditions are described as "clean" with a 4ft SSW swell and a combined energy of 772. For Blacks Beach, that’s the moment. It’s still an expert wave and crowds are inevitable, so get there early, but that morning is your best shot for the whole 16 days.
Keep your expectations low until that last weekend. It’s a waiting game.

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.
