Table - best surf conditions forecast for Blacks Beach over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Blacks Beach is pretty grim. There’s a long stretch of nothing worth paddling out for, so don’t get your hopes up. We’ve got a whole lot of small, weak, and onshore conditions, with a bit of a pulse showing up way down the line, but it’s a long wait.
The first recommendation doesn’t come until Saturday, July 11th, and even then, it’s a tough sell. Saturday morning sees some clouds, a light cross-on breeze from the SSW at 9 mph, and a modest 3 ft swell from the SSW. The period is a very long 15 seconds, which is a proper groundswell, but it’s hitting a beach break, so it’ll be breaking straight and lumpy. The wave energy is moderate (442), but the water is a crazy 72°, which is a massive 5° warmer than normal – that’s very unusual. The surf is poor, and the wind is cross-on, making it choppy. Saturday afternoon and Sunday morning are “marginal” at best, with tiny 3 ft waves and onshore winds. The whole week after that is a write-off. From July 12th right through to July 25th, we’re looking at a solid two-week stretch of nothing but poor surf conditions, with occasional small 2 ft to 4 ft swells, but always with that cross-on or onshore wind messing things up. The combined energy stays mostly in the 200-300 range, which is weak. It’s a dead zone.
Now, the only glimmer of hope comes at the very end. On Saturday, July 25th, the afternoon shows a 4 ft swell from the SW with a very long 20-second period, and the combined energy jumps to a strong 955. That’s a proper pulse. The wind is onshore from the W at 9 mph, but it’s still just “marginal” and questionable for tides. Sunday, July 26th, is the best on offer, but it’s still not a standout. The morning has some clouds, a light cross-on from the WSW at 6 mph, and a 3 ft SW swell at 18 seconds. The energy is still strong (743), and the wind is light, so it might be cleaner than anything else we’ve seen. The afternoon gets a bit better with a 4 ft SW swell, 18-second period, and a strong 921 energy, with the wind turning onshore from the W. It’s promising, but it’s a long-range call, so take it with a pinch of salt. Crowds are likely here, so don’t expect privacy.
Stick to the longboard or a fish if you’re desperate, but honestly, this is a kite-surfing setup for most of the run. The small, weak swell and strong cross-shore wind won’t do much for a surfer, but a kiter would have a blast.
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.
