The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, the next 16 days are a bit of a grind. The swell is on the small side and the wind is rarely your friend. The first few days are a write-off, with poor surf conditions and a bunch of zero scores. The best of the whole period is a stretch around the 25th of July through to the 28th, but even then it’s only marginal.
The standout spot is Blacks Beach. This is an exposed, consistent break, but don’t expect perfection. The water is sitting at 73°F, which is much warmer than normal for this time of year – a solid 6°F above average, so you might not need a full wetsuit.
The first real hope comes on Tuesday the 21st of July. The swell is 4ft from the SSW with a 16-second period, giving a moderate combined energy of 721. The wind is cross-on from the WSW at 9 mph, so it’s a bit choppy. It’s a marginal call, but it’s the first sign of life.
The best window starts on Saturday the 25th of July. The morning shows a 3ft SSW swell, but the period is a very long 21 seconds, and the combined energy hits a strong 1159. The wind is light and offshore from the WSW at 6 mph, keeping things clean. This is a long-period groundswell, so expect good shape but longer waits between sets. It’s a point break setup here, so it should handle that period well.
Sunday the 26th of July is similar, with a 4ft SW swell, 19-second period, and energy at 1150. The wind is light and cross-on, so there’s a little texture, but it’s still a solid option.
Monday the 27th of July picks up a touch more size, with a 4ft SSW swell and 18-second period, energy at 1233. The wind is offshore in the morning, making it the cleanest of this run. This is the best call of the whole outlook.
Tuesday the 28th of July holds similar 4ft SSW swell, 17-second period, and energy at 1145, but the wind goes cross-on again. Still worth a paddle.
After that, the swell drops off and the wind stays messy, with another gap of poor conditions from the 30th of July into early August. There’s a brief pulse on Sunday the 2nd of August with a 5ft SSW swell, but the period is a short 10 seconds, so it’ll be weaker and less defined.
For a consistent, exposed break like Blacks Beach, the best bet is the morning of Monday the 27th of July. Swell is 4ft from the SSW, with a long 18-second period, and the wind is light and offshore. It’s the cleanest, most powerful window in the whole 16 days.
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.
