The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Honestly, I gotta be straight with you – it's a tough stretch ahead. The first real surfable day we're looking at is Monday the 7th, and even then it's a bit of a mixed bag. We've got some solid swell rolling in, but the wind is a pain in the arse and the quality is just not there. For a spot like Blacks Beach, which is a known heavy hitter, it's a bit of a letdown.
Let's start with what's on offer. The period kicks off with a bit of a wait. Saturday the 5th and Sunday the 6th are write-offs with poor surf conditions and cross-onshore winds. By Monday morning the 7th, we finally see some life. A 6ft SSW groundswell is pushing in with a raw wave energy of 1225 (moderate to strong), and the period is a solid 13 seconds. That's got some proper grunt. But here's the rub – the wind is a gentle cross-on from the WNW. That's going to chop it up and keep it messy. The forecast calls it marginal, and I'd agree. It's not going to be the classic Blacks we dream about. That afternoon the wind picks up a bit, making it even choppier.
Tuesday the 8th is more of the same. The swell drops a touch to 5ft in the morning and 5ft in the afternoon, but the cross-on wind from the NW and then lighter NW doesn't clean it up. The energy is still moderate (887 in the morning, 628 in the afternoon). It's still a marginal call.
From Wednesday the 9th right through to the end of the forecast window on the 20th, the outlook is grim. The swell drops off significantly, mostly sitting between 2ft and 4ft, and the wind is almost always cross-on, cross, or onshore. The few times the wind is offshore, the swell is tiny. The wave energy drops into the low hundreds, and the scores are either zero or one. It's a long, dry spell.
The one standout, if you can call it that, is still Monday the 7th. That 6ft SSW swell at 13 seconds is the biggest energy we see. But with the persistent cross-on wind, it's going to be a frustrating day. You'll see occasional bombs, but you'll be fighting the chop. It's a day for the experienced crew who know the break and can handle the messy conditions. The water temp is a balmy 73°F, which is much warmer than normal for this time of year, so you won't need a thick wetsuit.
Given the persistent cross-onshore wind and the beachbreak nature of the spot, the conditions are more appealing for a kite session than a classic paddle-out for most of the forecast. The period from Tuesday the 8th afternoon onward is a real blank run. It's a tough one, but that's how it goes sometimes.
Rusty.

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.
