The Lowdown
Alright, let me tell you straight. The next couple of weeks over at Blacks Beach look pretty flat and weak. We’ve got a long stretch of poor surf ahead, so don’t get your hopes up for anything stellar. It’s one of those periods where you’ve gotta pick your moments.
For a break this exposed, we are looking at mostly small, wind-affected surf. The water temp is sitting at about 72°, which is a touch warmer than normal for this time of year, so at least you won’t need a thick suit.
The next week is pretty grim. Thursday the 10th through to the following Wednesday are all poor, with surf heights struggling to get over 4ft and periods mostly in that short, weak range. The wind is all over the place, mostly cross and cross-on, which will chop things up. There is some very long period swell showing on Sunday the 13th, but it’s tiny at 4ft, and a 7-second period is useless. Later on Monday the 14th, we see a slight bump in period to 8 seconds but the height drops off.
The energy is mostly weak to moderate through this whole first stretch, with values between 251 and 557, so there’s just not enough push.
Now, things start to look a little more interesting as we head into the following week. There’s a glimmer of hope around Saturday the 19th and Sunday the 20th. The swell stays small, around 3ft to 3ft, but we get a bit more consistency showing up, and the wind lightens off. It's still cross-on, but those light breezes are a major positive for getting a bit of shape on the waves. The energy levels are starting to build back up through the 600s and into the 700s by Monday the 21st.
That Monday the 21st looks like the pick of the bunch, with a 4ft SW swell with a 17-second period. That’s a real groundswell with some proper energy. It should offer some cleaner lines than the wind-chopped slop we’ve seen, especially for Blacks. But with the long period, and being a beach break, it might be a bit straight. There’s also a strong NW wind state showing here, which can make it interesting for the kitesurfers.
Beyond that, it fades again quickly. The end of the month looks pretty lackluster. We do see another long-period pulse around Friday the 25th, with a 21-second period, but the height is only 2ft, so it’s more of a promise than a payoff. The energy is moderate at 668, but it just won’t translate to rideable waves.
So, my honest take: if you’re desperate, the weekend of the 19th and 20th, and especially Monday the 21st, are your best shots. It's not going to be epic, but it’ll have more going for it than anything else. Keep an eye on those light wind windows. Other than that, it’s a poor stretch.

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.
