The Lowdown
Alright folks, Rusty here. Let’s get stuck into this one.
Look, I’ve got to be straight with you – the next couple of weeks are looking pretty grim for Blacks Beach. We’ve got a bit of a flat spell to start, then a few days of small, cross-onshore junk that’s barely worth a paddle. The water’s sitting at 75°, which is a whopping 8° warmer than usual for this time of year – that’s a proper tropical anomaly, feels more like a bath than the Pacific.
The first real chance to get wet doesn’t come until Friday the 24th of July, but don’t get your hopes up. It’s a tiny 2ft from the SW with a 24-second period. That’s a very long period groundswell, which means it’ll be fat and straight at a beach break like this – better suited to a point or reef. The energy is moderate (669), but the wind is a light cross-onshore, so it’s going to be choppy and messy. The rating is poor, and it’s consistent, but honestly, it’s a struggle.
Saturday the 25th and Sunday the 26th are more of the same: 3ft to 4ft from the SSW-SW, with that same long period (21-18 seconds). The energy bumps up slightly (924-975), but the cross-onshore wind keeps it from being clean. You’ll get a wave, but it’ll be a bumpy, work-for-it session.
Things pick up a bit Monday the 27th and Tuesday the 28th. The swell pushes to 4ft-5ft from the SSW, with a shorter period of 17-19 seconds, and the energy climbs into the strong range (1177-1251). This is the best the forecast has to offer, but it’s still not great. The wind is still cross-onshore, making it choppy and not the clean, peeling Blacks we dream of. The optimum swell direction is WNW, but we’re getting SSW-SW, so the shape will be off. For a more experienced surfer, this might be okay for a workout, but it’s not a standout. It’s for advanced surfers only.
After that, it drops off a cliff. Wednesday the 29th through to Friday the 7th of August is a long, dry gap. The swell is tiny (1ft-2ft), the period is short, and the wind is mostly onshore or cross-onshore. The energy is weak (19-222). Many days have a score of zero. It’s not worth looking at.
Then there’s a last flash on Saturday the 1st of August. The afternoon shows a sudden 6ft from the SSW with a 13-second period and strong energy (1092), but the wind is onshore from the WSW, making it a messy, blown-out wall. That’s a kite-surfing setup, not a paddle-surfing one. For a surfer, it’s a miss.
The crowd factor at Blacks Beach is listed as "often", so when there’s anything rideable, expect company. But with this outlook, you’ll likely have the place to yourself, which says it all.
Rusty, signing off.

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.
