The Lowdown
Right then, let's have a look at what's on the table.
Honestly, it’s been a bit of a flat, frustrating run lately, and this 16-day window is looking like more of the same for the most part. We’re not getting any proper pulses of swell that line up with clean conditions, so we’re going to have to be patient. There’s a bit of a tease around the middle of the period, but overall, the quality’s low.
The water is sitting at a very rare 76°, which is 7° warmer than normal for this time of year—pretty wild, you’d almost think it was summer.
We kick off Wednesday the 2nd with small, long-period groundswell, but the “poor surf conditions” tag says it all. By Friday the 4th, things get a little more interesting. The morning shows a clean 3 ft from the SSW at 17 seconds, light cross-onshore wind, and a combined energy of 623 (moderate). It’s only rated as marginal though, and tide might be an issue. Saturday the 5th is similar: 4 ft SSW, 16 seconds, and a light offshore wind from the west in the morning, making for a glassy surface. The energy is 636 (moderate). It’s still only a marginal call, but if you’re keen, Saturday morning is your best chance for something clean and rideable.
Then it drops off again. Sunday the 6th is tiny and messy, and Monday the 7th sees the swell jump to 6 ft from the SSW at 13 seconds, with a solid 1131 energy reading (strong), but the wind is cross-onshore and it’s fairly choppy. Tuesday the 8th is similar, with a 6 ft SSW swell at 12 seconds and offshore wind, but the scores are still low due to poor surf quality. It holds at about 5–6 ft through the 8th and 9th, but the wind is never quite right for Blacks.
From the 10th onwards, it fades back into small, weak, and inconsistent junk. There’s a slight uptick on the 17th with a 3 ft SW swell from a very long 21-second period, giving an energy of 786 (moderate), but it’s another marginal call with light offshore wind. That long period means it’ll be fat and straight at this beach, but if you’re an expert and the tide’s right, there might be a sneaky one.
Bottom line: there’s no true standout in this 16-day window. There’s a short, promising window from Friday the 4th to Tuesday the 8th where the swell is okay, but the conditions are never clean enough to call it a highlight. Saturday morning the 5th is the closest we get to a decent wave, with clean offshore wind and a moderate 4 ft SSW groundswell. But don’t expect much.
The long stretch of poor surf is fairly normal for this area when the trade winds don’t play ball. It’s one of those times where the setup looks more interesting for kite surfing than paddle surfing.

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.
