The Lowdown
Hey, Rusty here. Let’s run through it.
The whole 16-day picture for Blacks Beach is pretty flat and bumpy. Starting Friday morning the 28th of August, we’ve got tiny 2ft swell from the SW at 16 seconds, with a cross-on SW wind at 6 mph. Combined energy is weak at 359, and the water sits at 76°F with a much warmer than normal anomaly of 4°F. Poor conditions with light cross-onshore breeze and little wind ripples. Friday afternoon: 3ft from the SSW, 19-second period, still cross-on, marginal forecast, energy moderate at 583.
Saturday the 29th: morning 4ft SSW at 16 seconds, onshore WSW wind at 9 mph, energy 753. Afternoon 4ft SSW, onshore WNW wind 9 mph, energy 845. Both marginal—offshore breeze means bumpy surface. Sunday the 30th: 4ft in the morning with cross-on SW wind, 3ft afternoon with onshore W wind. Still marginal.
Monday the 31st through Wednesday the 2nd of September is all poor: swell runs from 2ft to 3ft, onshore winds, weak energy between 139 and 523. Thursday the 3rd of September shows 4ft SSW at 15 seconds, onshore WSW wind morning (energy 857), and onshore W wind afternoon (energy 1038). Marginal both times with moderate to strong energy but messy wind.
Friday the 4th of September morning has 3ft SSW at 17 seconds, light cross-on WSW wind at 6 mph, energy 911. Long period but cross-onshore ripples. Afternoon turns poor. Saturday the 5th gives 4ft onshore in the morning, cross-on in the afternoon, marginal or poor.
From Sunday the 6th through Saturday the 12th of September, it’s mostly poor with small 2ft to 3ft swell, onshore or cross-onshore winds, and weak energy. The only slightly better moment is Saturday afternoon the 12th: 5ft SSW at 12 seconds, cross-on SSW wind at 9 mph, energy 666, but still marginal and choppy.
No real standout here. The best shot is Thursday the 3rd of September afternoon with 4ft and strong energy (1038), but that onshore wind spoils it. For an advanced spot like Blacks Beach, it’s a rough stretch. With mostly onshore wind and small, mediocre waves, this might be more tempting for kite surfing than paddle surfing.
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.
