The Lowdown
Alright folks, Rusty here. Let’s look at what’s cookin’ for Blacks Beach. It’s a bit of a stop-start forecast, with some real energy later on, but don’t expect perfection every day.
First off, Blacks Beach is a consistent, exposed spot for the advanced crew. The water is 74° and that’s 6° warmer than usual for this time of year – that’s a big deal, a real anomaly. Get ready for warm water.
We’ve got a little something Friday the 14th afternoon into Saturday the 15th morning. Swell is small, around 3ft to 3ft from the SSW with a long 16–18 second period – that’s groundswell, but the combined energy is moderate (665). Wind is onshore from the west at 9 mph, so it’ll be a bit lumpy. Nothing to write home about.
Sunday the 16th morning could be your best early call. Lighter wind from the WNW at 6 mph, swell still 3ft from the SSW (15 seconds, energy 508). Still marginal, but the glassier start might give you a few clean ones.
After that, the surf goes flat and sloppy. From Sunday the 16th afternoon right through the next week, it’s mostly poor to marginal with tiny waves, onshore or cross-onshore winds. That’s a dry spell of about 8 days with no good options.
Things finally wake up on Thursday the 27th of August. The swell hits 5ft from the SSW (14 seconds, energy 1150). Winds are light offshore from the west at 6 mph in the morning. This is a proper pulse, but at over 5ft, it’s for experienced surfers only. Thursday afternoon still has good size, but a light onshore wind will mess with the surface a bit. Still, that’s your best chance.
Friday the 28th morning holds at 5ft from the SSW (13 seconds, energy 1154) but wind turns cross-onshore from the SW, adding some bump. Still surfable for the die-hards.
Saturday the 29th morning drops to 4ft but with an 18-second period (energy 1061) and lighter cross-onshore wind. That long period at Blacks, a beach break, might make the waves a bit fat and straight, but the power will be there.
My pick: Thursday the 27th afternoon into Friday the 28th morning. That’s the biggest, most energetic swell of the window, especially if you can get that offshore wind early. It’s over a week away, so stay tuned, but it’s got potential.
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.
