Alright, this is Rusty. Let's break it down.
Look, I gotta be straight with you – the next few weeks are looking pretty flat and uninspiring around here. There’s a lot of small, weak swell and tricky winds on the cards. The energy just isn't there for most of the period. We’ve got a long stretch of marginal-to-poor conditions, and I wouldn't get my hopes up for anything decent until much later.
We start off on Monday, 6th of July at Blacks Beach. The swell is tiny, only about 3ft from the SSW, but the period is a very long 16 seconds. That’s a proper groundswell. The wind is a clean offshore from the W at 9 mph, which is a major positive and should keep the faces clean. The combined swell energy is moderate at 538. The water temp is about average for this time of year. But the model is flagging it as marginal due to tide or the small size, so it’s not going to be easy to get a good one. The long period might make it break a bit straight on a beach, but with that offshore wind, it could still offer a few long, walling runners for the patient surfer.
Tuesday the 7th is more of the same – a touch more size at 3ft, but still with that long 18-second period and clean offshore wind. Still, it’s being called marginal. You might get a sneaky one.
Then things go downhill. From Wednesday the 8th through Sunday the 12th, we get a mess of cross-onshore winds with swell staying between 3ft and 4ft. The period drops from 16 down to 14 seconds. The energy is in the moderate range (highest is 857), but the wind just ruins it, making it choppy and poor.
From the 13th of July through to the 20th, it’s a real drought. Swell sizes drop to between 1ft and 3ft, with combined energy mostly in the low hundreds, even dropping to two-digit numbers like 37 on the 21st. The wind is mostly light or gentle, but it’s cross-onshore or onshore, and the swell is too weak to bother with.
The one tiny glimmer in this whole 16-day stretch is Saturday, 18th of July. We see a bump in swell energy back up to 516, with 3ft from the SW and a long 17-second period. The morning has a light cross-onshore from the WNW at 9 mph, which isn’t ideal but is manageable. It’s still marginal, but it’s the best-looking day in the second week. Keep an eye on that one, but treat it as a promising possibility, not a certainty.
Honestly, for the rest of it, the waves are just too small and the wind is too messy. For a powerful spot like Blacks, this stretch looks more interesting for a kite surfer than a paddle surfer, especially when the cross-shore winds hit.
It’s a real bummer, but that’s the way it goes sometimes. Forecasts can change, but right now, I’d find something else to do for the next two weeks.

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.
