The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Alright, straight up, this is a tough one. We're looking at a long stretch of marginal to poor conditions, but there are a couple of windows where it might just be worth paddling out. The key word here is patience.
For the first few days, from Saturday the 22nd through to the end of August, it's a write-off. The swell is small, the direction is all over the place, and the wind is mostly cross-onshore, killing any chance of a clean wave. The energy is low to moderate at best, with combined energy readings stuck between 104 and 820. You can leave the wetsuit in the car for that stretch.
The first real glimmer of hope comes on the morning of Tuesday the 2nd of September. The swell bumps up to 5ft coming from the west, but the period is a short 8 seconds, meaning it's gonna be a bit lumpy and weak. The wind is a light cross-onshore, so it won't be glassy, but it's the biggest swell we'll see. Even then, the combined energy is only 588, so it's not firing. This is more of a "maybe for the core crew" kind of session.
Then, the latter part of the outlook gets interesting. From Thursday the 4th of September through the 6th, we see a change. The swell drops back to 3ft to 4ft, but the direction swings to a consistent SSW and the period stretches out to a very long 16-18 seconds. That's proper groundswell energy. With the wind going light and offshore from the west, this is our best bet. The combined energy is strong, hitting 715 to 803, which is a solid step up. This is the standout period.
Now, for the pick of the breaks. Blacks Beach is the only spot on the radar, and it's a consistent, exposed reef break that handles a long period swell well. The water temp is about average for this time of year. For that first window on the 2nd of September, the 5ft W swell is a bit short-period, but it's the biggest. However, the real gem is the 4th, 5th, and 6th of September. That 3ft to 4ft SSW groundswell with a 16-18 second period and light offshore winds is where it's at. The waves will be clean, lined up, and have that proper push. It's an advanced break, and with crowds often being an issue, you might have to share the peak, but for that quality, it's worth it.
So, to sum it up: the next week and a half is a waiting game. Don't bother until the 2nd of September if you're desperate, but mark your calendar for the 4th through the 6th. That's the window where the stars align at Blacks Beach. It's still a week out, so keep an eye on it, but it looks promising.
Rusty, 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.
