The Lowdown
Alright, grab your coffee, let’s have a look at what’s coming down the line.
First up, the outlook for Blacks Beach. We’re looking at a drawn-out, frustrating stretch ahead. The next week is pretty average to poor, with no real standouts. The first few days are basically a write-off with minimal energy and questionable conditions.
From Thursday the 3rd right through the weekend, you’ve got small swell, mostly under 3 ft, with a long-period SSW groundswell running. The problem is that even though the period is long, the wave heights are tiny and the wind is blowing right onshore, so it’s messy. Combined energy sits around 427 to 700, so it’s weak. Not worth paddling out for.
Things start to lift a bit from Monday the 7th. Swell picks up to 6 ft from the SSW, with a period of 14 seconds and combined energy jumping up to 1411 (moderate energy). That’s a real step up in power. The wind is light offshore from the WNW in the morning – that’s clean. But the ratings are still only marginal; the tide and shape might not be cooperating perfectly. This is the best bet in the entire 16-day window. For a more advanced crew, Monday morning might have a few solid ones, but it’s not going to be epic. Tuesday the 8th still has some size at 6 ft in the morning, again with light offshore wind, but the energy drops off a little.
After that, the swell fades fast. From Wednesday the 9th onwards, we’re back into small, weak surf with poor conditions. The wind stays mostly onshore or cross-onshore, the period gets shorter, and combined energy sinks back below 600. The last week of the forecast is pretty flat and choppy, especially around the 12th to the 18th. A few spots on the 13th and 14th have long-period leftovers, but the heights are under 2 ft – not worth a session.
Water temperature? No anomaly noted, so it’s about average for this time of year. Blacks Beach is an exposed beach break, so when the swell is over 5 ft and the period is long, it can get a bit straight and dumpy. But with the wind going offshore, Monday the 7th morning is your one real shot. For beginners, the 6 ft is a bit much; this is for the experienced crew.
Bottom line: one semi-decent window on Monday the 7th morning. Otherwise, a pretty quiet 16 days.

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.
