The Lowdown
Alright folks, Rusty here. I won't sugarcoat it – this 16-day stretch for Blacks Beach is a tough slog. Honestly, the data is screaming "poor surf conditions" almost the entire time, so we're not looking at any classic days. The water temp is way warmer than usual, about 76°F, which is a massive 8°F above average – feels like a bathtub out there.
The first chance for a paddle comes Friday, August 7th, and through that weekend, the surf is tiny. We're looking at 2 to 3ft swell from the SSW. The period is long, 15 to 19 seconds, which gives it some deep ocean energy, but the combined wave energy is only moderate. With such a long period on a beach break, these small waves just hit the sandbar and go straight up – no wall, no fun. The wind is offshore, light from the W, so it's clean, but there's nothing to ride.
Through the rest of the first week, Monday 10th to Thursday 13th, the story stays the same. Swell is 2ft and weak. The wind is mostly cross-offshore or light, but the lack of size means you're just fighting for a half-roll. It's frustrating.
Now, around Friday the 14th and Saturday the 15th, we see a tiny bump. Swell gets up to 3ft, and the energy climbs into the solid moderate range, even hitting the 600s. The catch? The conditions are still 'marginal'. That long-period swell (16-18 seconds) will just jack up and close out on the beach break. Saturday afternoon has an offshore breeze, so it might look tempting for a second, but don't expect much more than a closeout wall.
From Sunday the 16th all the way to Saturday the 22nd, it's back to flat or near-flat conditions. Waves drop to 2-3ft, with cross-onshore winds making it choppy and messy during the week. The last few days have lighter winds, but the swell is gone. You're looking at over a week of very weak, poor-quality surf.
For a consistent spot like Blacks, this is a real bummer. With the long, weak groundswell and those cross-onshore winds, honestly, this looks way more interesting for a kite surfer than for a paddle surfer. There's just nothing to work with for the board.
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.
