The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for the coming weeks.

Overall, it's a bit of a slow burner. We've got a lot of days ahead with small, messy surf and poor conditions. Don't get your hopes up for anything world-class, but there's a couple of windows where things might just line up for a session.

The action starts on Friday the 31st of July, but it's a tough call. The morning has some hope with a 4ft SSW groundswell, a very long 14-second period, and light offshore west winds. That offshore breeze is a huge plus, meaning the waves could be clean. The combined energy is moderate at 612, so there's some push. But the forecast calls it marginal, and honestly, for a spot like Blacks Beach (San Diego) that's exposed to WNW, this SSW swell isn't the ideal direction. The water is much warmer than usual for this time of year, sitting at 76°F, a solid 8°F above average, which is very unusual.

From Friday afternoon onwards, we hit a real flat spell. Saturday and Sunday the 1st and 2nd of August see the swell dropping below 3ft, with light but often cross-onshore winds. The energy values are weak, and the surf is labelled as poor. This lull stretches right through the first week of August. Monday the 3rd through to Saturday the 9th all show tiny surf, mostly under 3ft, with a mix of light offshore and cross-onshore breezes. The combined swell energy stays low, mostly between 117 and 421. The waves are either too small or too chopped up. It's a long stretch of nothing special.

Things start to look a bit more interesting towards the second week. On Monday the 10th of August, we see a small 3ft SSW swell in the morning with clean offshore west winds, but it's still a poor forecast. However, the real standout window appears to be the weekend of the 15th of August. On Saturday the 15th, the morning session offers a 4ft SW swell with a solid 16-second period, and the winds are light and offshore from the west. That's the recipe for clean, lined-up waves at Blacks. The combined energy is a strong 634, showing there's some decent power behind it. It's a groundswell with a long period, which can make for some long, walling waves, but it also means longer lulls between sets. This is a true standout for the whole forecast, but it's over two weeks away, so treat it as a promising long-range call, not a certainty.

The afternoon of the 15th and the Friday before also show marginal surf, but the Saturday morning is the one to circle on your calendar. The crowds at Blacks Beach are often there, so don't expect it to be empty if the swell shows.

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.
