Updates in hr min s Forecast update imminent
Alright, Rusty again. Let's talk about Blacks Beach in feet and miles per hour. The truth is, it's looking pretty grim for the next couple of weeks.
The first chance to get wet is Monday afternoon, July 6th, but don't hold your breath. We've got a tiny 2ft swell from the SSW with a crazy long 20 second period. That's a groundswell that *could* produce some shape, but at that size and with weak energy (745), it's a marginal situation. The water is a wild 70°, which is *much warmer than normal* for this time of year, about 4° above average. That's super unusual. Winds are good, though, blowing offshore from the WNW at 9 mph, which is a major plus for clean waves. But the small size and long period mean it's probably just closing out. It's not the standout we're after.
Tuesday the 7th is more of the same – similar size (3ft) and a long period (18 seconds) from the SSW. Winds stay offshore from the west at 9 mph. The combined energy is still moderate (852). But the real trouble starts Wednesday the 8th and runs through pretty much the rest of the forecast. It's mostly cross-onshore or onshore winds, with swell heights bouncing between 1ft and 4ft, but the wave quality is consistently flagged as "poor" or "marginal." The combined energy drops way down, often below 500, which is weak. The wind is rarely your friend, staying cross or cross-onshore from the SSW and SW for most days, with speeds around 9-12 mph. That's going to make a mess.
There are a few afternoons with offshore wind, like Tuesday the 14th and Wednesday the 15th, but the swell is tiny – 2ft or 2ft – and the energy is just not there. It's not worth a drive. Saturday the 18th and Sunday the 19th see a little pulse of energy (450 and 600 combined energy) but that comes with a moderate cross-shore breeze from the SSW at 12 mph, making for choppy, rubbish conditions.
Honestly, for Blacks Beach, there’s no true standout session in this whole 16-day window. The setup looks more interesting for a kite surfer than a paddle surfer on most of these days, especially with the persistent cross-shore winds and small, poor-quality surf. The only real bright spot is the Monday afternoon offshore wind on July 6th, but the tiny swell with that very long period makes it a lottery. For now, leave the board in the car and check back next week. Things can always change.

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.
