The Lowdown
Alright, let’s break this down.
Honestly, it’s a tough stretch ahead for Blacks Beach. We’ve got a long run of marginal and poor conditions that dominate most of this 16-day window. There’s no proper standout session, but if you’re desperate, the pick of a pretty average lot falls on Saturday the 1st of August.
We start off this Saturday, the 25th of July, with a small cross-onshore 3ft SSW groundswell rolling in with a very long 21-second period. The combined energy is moderate (924), but the wind is a light cross-on breeze, and the conditions are described as marginal with questionable tide. It’s not going to be clean. That same low-quality story carries right through Sunday and Monday, with the swell bumping up a little to 4ft–4ft on a SSW direction, period dropping from 19 down to 17 seconds. The cross-onshore wind sticks around, now a gentle breeze, so it's choppy. Wave energy climbs into the strong range (up to 1275) but that doesn't help with the messy surface.
By Tuesday the 28th, it’s still cross-onshore with 5ft–4ft SSW swell, period dropping further to 17 seconds, and energy strong but dropping. Honestly, the surf quality is just not there – still marginal at best.
Then we hit a real dead patch. From Wednesday the 29th of July right through to Sunday the 9th of August, it’s mostly “poor surf conditions” with scores that don’t warrant a paddle out. Swell sizes drop right off, down to 2ft–3ft, periods all over the place, and energy levels sink from moderate to weak. Winds stay cross-on or onshore, no real clean windows.
The only faint glimmer is Saturday the 1st of August. Morning shows 5ft of SSW swell with a 13-second period, coming in with moderate energy (884), and the wind is light and onshore. Afternoon holds at 5ft, same direction, 12-second period, energy dropping to 680, still onshore but light. It’s not great, but it’s the biggest push of the whole outlook. The wind’s not offshore, but the light onshore might not trash it completely. If you’re an advanced surfer and you’ve got to get wet, that morning could offer the most size. But that’s stretching the definition of a highlight.
Water temp? No anomaly data given here, so we’ll call it about average for this time of year.
No crowd data in the finder, but Blacks is known to be busy often – factor that in.
Bottom line: there’s no proper standout. The 1st of August is the best on offer, but it’s mediocre. Don't expect much. From the 29th of July there’s a long gap of over a week with nothing worthwhile – that’s a grim stretch.
Stay patient, mate.

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.
