The Lowdown

Alright, boys and girls, let's get into it. Blacks Beach is looking at a pretty grim stretch ahead. The Finder is showing me that there's not a single session that's worth a paddle out, so I'm calling it for what it is: a real flat spell.

The forecast starts on Sunday, 16 August, and it's already a bust. The swell is a tiny 3 ft from the SSW, but the wind is onshore or cross-onshore, and the surf is rated as poor. The combined energy is moderate, coming in at 513 (moderate), but it's all for nothing. From there, we're looking at a long run of small, weak, and messy conditions. The swell stays between 2 ft and 3 ft for the entire first week, with the wind mostly light and onshore or cross-onshore. The period is long, between 14 and 19 seconds, so there's groundswell energy, but without the size, it's just a tease. The water temp is about average for the season.

By Friday, 21 August, we get a hint of "marginal surf" with a score of 1, but that's about as exciting as it gets. The swell is only 2 ft, and the wind is cross-onshore. It's a total loss. The next week, starting Sunday, 23 August, the swell period jumps up to 19 seconds, but the height is still only 2 ft to 2 ft. The combined energy stays moderate, between 334 and 386 (moderate), but it's just not enough to overcome the lack of size and the onshore winds.

The last few days of the month, around 29 and 30 August, show a slight bump back to 3 ft, but the wind is still cross-onshore, and the surf is still marginal or poor. The combined energy gets up to 585 (moderate) on the 29th, but again, the wind and small size ruin it. This is a tough stretch for Blacks Beach, with no real options anywhere in the 16-day window. It's a blank run, plain and simple.

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.
