The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Blacks Beach.

Right off the bat, I gotta be straight with you – the next few days are looking pretty grim. We’re into a bit of a quiet spell. For Monday the 20th and Tuesday the 21st, we’ve got some small swell rolling in, but the wind is on it, and the conditions are just poor. It’s not really worth paddling out for. You’re looking at a weak, messy energy reading around 352 to 822 (combined energy), and the surf is just not shaping up.

Wednesday the 22nd and Thursday the 23rd aren’t much better. The wind goes cross-onshore, messing up the surface. We’ve got some knee-to-waist high swell from the SSW, but it’s carrying that long period – 14 to 15 seconds – which is a groundswell, but it’s just not finding the right groove here with the wind chop. It’s a frustrating stretch.

We finally get a little glimmer of hope on Saturday the 25th. The morning shows a bump in energy, jumping to 1230 (combined energy), with a clean 3ft SSW groundswell at a very long 21 seconds. But the wind is light cross-onshore, so it’s still a bit textured. It’s a marginal call, but if you’re desperate, the early session might offer a few.

Sunday the 26th and Monday the 27th start to build some more. We’re seeing 4ft to 4ft from the SSW, with periods of 18 to 19 seconds, and the energy is solidly in the four-digit range (918 to 1222). That’s moderate wave energy, and it’s starting to feel like there’s some power in the water. But again, the wind is mostly cross-onshore, so it’s not clean glass. The best bet during this stretch is probably the early mornings when the breeze is lightest.

Now, the standout window looks like Tuesday the 28th. The swell holds at 5ft from the SW, with a period of 17 seconds, and the combined energy peaks at 1239. This is moderate wave energy, and it’s the biggest, most consistent pulse we’ve seen. The wind is still a light cross-onshore, but if that eases, Blacks Beach could have some proper lines. This is the one to circle on the calendar. After that, the week of the 29th to 31st sees the swell drop back down, and we’re back to weak, poor conditions.

Then, looking out to Saturday the 1st of August, we get another spike – 5ft from the SSW. That’s getting into the bigger range, and though it’s a shorter period at 13 seconds, it’s a significant pulse. The winds are onshore, though, which will mush it up. For the experts, it might offer some grunt, but it’ll be a battle.

Honestly, the window from Tuesday the 28th into Wednesday the 29th is the most promising. Crowds are likely at Blacks Beach, especially if it cleans up. The water temperature is about average for the time of year, nothing unusual there.

After that, the first week of August fades into small, weak leftovers. The long and short of it is: wait for that Tuesday the 28th window, and keep your fingers crossed for the wind to play nice.

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.
