The Lowdown
Alright, let’s break down what’s in store for Blacks Beach.
Honestly, the first week-plus looks pretty grim. Swell is coming in from the SSW and SW, but the wind is either cross-onshore or onshore nearly the whole time. Wave heights are small to moderate, and the combined energy is mostly in the 350-600 range – just not enough to get excited about. There’s a big gap at the start with no real surf worth mentioning.
Things finally show some life on Saturday, July 25th. The morning brings 0.8m from the SSW with a super long period of 21 seconds. That long period means real power, and the combined energy jumps to 1085 – that’s strong. The wind is a light cross-onshore, so the surface should be pretty clean. This is the first real standout. Blacks is an exposed reef, so that long-period swell might wall up and break a bit straight, but for experienced surfers, this is the best bet so far.
Sunday, July 26th keeps the trend – 1.1m from the SW, period at 19 seconds, combined energy at 1147. Again, light cross-onshore breeze. It’s not glassy, but it’s rideable. This spot gets crowded often, so don’t expect solitude.
Tuesday, July 28th afternoon sees the swell bump up to 1.4m from the SSW at 17 seconds, with combined energy at 1207. That’s a lot of water. Wind is a gentle cross-onshore, so it’ll have a bit of texture, but for advanced guys, this is the biggest, most powerful window of the first two weeks.
Looking further out, Saturday, August 1st afternoon could be the biggest of the whole outlook: 2.0m from the SSW with a 12-second period and combined energy of 1219. Onshore wind will make it rough, but if you’re an expert looking for size, that’s your day. For everyone else, it’s a pass.
The real standout is Saturday July 25th for the cleanest mix of long-period groundswell and light wind. Sunday July 26th is a close second. The rest is mostly small, choppy, or too big and messy.
Stay safe out there.

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.
