The Lowdown

Alright, let’s get real about the next little while. We're looking at a flat and weak stretch for Blacks Beach. Lots of small, short-period swell from the SSW that just doesn’t have any punch. It's going to be a grind, with the first few days being especially weak.

Sunday, August 16th starts us off with a meager 3.3ft of SSW swell, with a period of 15 seconds. The wind is cross-on from the WNW at 9 mph, putting a little chop on the water. Water temp is 73°, which is a whopping 5° warmer than normal for this time of year—that's a real bonus if you're trying to stay warm. The combined energy is weak at 471, so there's no power. It’s going to be a bit of a fight for anything rideable.

Moving through the week, nothing changes. Monday and Tuesday are slightly smaller, still from the SSW with periods in the 14-16 second range. Winds are light and offshore in the mornings, which is good for keeping the surface clean, but the waves themselves will be tiny—around 2.3ft to 2.9ft. The energy stays weak to moderate, hovering in the 300-450 range, but it's all surface-level, gutless stuff.

By the end of the first week, Thursday and Friday, August 20th and 21st, things get even smaller and the period drops to 13 seconds. This is now just marginal, more for a longboard or a boogie board. The wind is still light but cross-on, adding some texture to already weak waves. This looks more like a float session than a surf.

The second week doesn't offer much hope. There's a slight bump in size on Saturday, August 22nd afternoon and again on Sunday, August 23rd, with 2.6ft and 2ft respectively, but it's still all from the SW/SSW. The 23rd has a 19-second period, but the height is only 2ft. It's a long-period groundswell, but there's no size, and on a beach break like this, it'll likely just roll through fat and unmakeable.

The only real standout is Saturday, August 29th. We finally see a jump in energy, hitting 618—the highest reading of the whole period. Swell is 3.3ft from the SSW with a 17-second period. The wind is light and cross-on from the SW. It's still not big, but there's finally some push behind it. This is the best of the bunch, but it's over a week and a half away, so don't hold your breath. The long period might make it a bit straight on the beach break, too.

Real talk: for the next two weeks, we're in for small waves and low expectations. The warm water is the only saving grace. Save your energy for the 29th, or find something else to do.

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.
