The Lowdown
Alright, listen up. We've got a long, flat stretch ahead for Blacks Beach. The next couple of weeks are looking pretty damn slow. The first week is basically a no-go, and the second week only shows a little bit of promise, but it’s still not much.
The first few days are tiny, with 2ft to 3ft swells and weak energy. It’s just not doing anything. The wind is mostly light and offshore, which would be sweet if there was any real swell to push around, but there isn't. Water temp is about normal for this time of year.
By Saturday the 8th, the swell bumps up a touch to 3ft to 3ft, and the energy starts to climb. Wind is still offshore and clean, but the waves are just on the edge of being worth it. It’s not really.
Sunday the 9th through Tuesday the 11th, the wind swings around to the southwest, making it cross-onshore and a bit choppy. The swell stays small, around 2ft to 3ft, and it’s messy. Poor surf conditions.
There’s a bit of a lull, but then from Thursday the 14th through Saturday the 16th, we finally see some better-period swell. The height is still small, 3ft to 4ft, but the period stretches out to 16-18 seconds, and the energy climbs. This is the most promising stretch. Wind is back to offshore and light, which will keep things clean. It’s still not big, but there could be some fun, longer-period groundswell lines. This is the best it gets.
After that, it fades back down to the 3ft to 3ft range with weaker energy, and the wind stays offshore but the swell just doesn't have any push.
So, to be honest, it’s a pretty lean 16 days. The standouts, if you can call them that, are the mornings on the 14th, 15th, and 16th of August. Even then, it's a small wave, but with that long period and offshore wind, a point break might be a better bet than this beach break. Don’t expect much, but if you’re desperate, that’s your window. There’s a long gap of flatness before that, so be patient.
Signing off.

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.
