The Lowdown
Alright, grab a seat. Let me tell you what’s happening.
Alright, listen. I’ll be straight with you – we’ve got a tough run ahead. The forecast for Blacks Beach over the next 16 days is mostly a story of tiny, weak, and often messy surf. The water temp is 76°F, but that's a whopping 8° warmer than usual for this time of year, which is very unusual and makes things feel a bit weird.
The first real glimmer of hope doesn’t show up until Thursday, August 13th but even then, it’s only a "marginal" call. We’re looking at small 2ft swells from the SSW, but with light onshore wind, it won’t be clean. That pattern basically holds through the first week. The combined energy readings are all in the triple digits – moderate energy – but the wave size just isn’t there to do much with it.
Honestly, nothing here is a standout. The biggest bump in size happens on Saturday, August 15th with an afternoon 4ft SSW swell, but the wind stays on it, so it'll be lumpy. The period stays around 14 to 18 seconds, which is a nice long groundswell, but for a beach break like Blacks, that long period often means the waves stand up and close out. You'd need a point or a reef to really make that work.
Then we hit a long, dry spell. From Monday, August 17th right through to the end of the window on August 25th, it’s all under 3ft. The energy readings drop into the low-to-mid 200s for most of that second week. The winds are mostly light and onshore, so you’ll get small, weak, choppy lines at best. It’s the kind of setup that looks more interesting for a kite than a paddle.
There’s no real "best on offer" here. The closest you get to a decent session is Sunday, August 16th, with that 4ft swell in the morning, but it’s cross-onshore. If you’re desperate, maybe paddle out on Friday, August 14th morning. The 2ft swell has a 18-second period and light onshore wind – it’ll be marginal, but you might snag a few clean ones if you’re patient.
Otherwise, it’s a long wait. For an exposed spot like this, it’s a quiet run, but these things can 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.
