The Lowdown

Alright, Rusty here again, but I’ll switch to feet and Fahrenheit for you.

Looking at Blacks Beach for the next couple of weeks, and I gotta be straight with you – it’s mostly a bust to start. The first week and a half is all small, choppy junk. Waves are 1 to 3 ft, with short-period or weak SW swell, and the wind is almost always cross-onshore from the SW or SSW. It’s bumpy, it’s messy, and there’s nothing worth chasing. Water temp is running about 74°, which is much warmer than normal for this time of year (just over 6° above average), so the water feels nice, but the surf is not.

There’s a long dry spell stretching from now until around the 20th of September. That Sunday finally sees a shift. Winds go light and onshore from the WSW, and we get a little bump in swell – still only about 3 ft, but with a longer period around 18 seconds coming from the SW. That direction isn't what Blacks Beach prefers (it wants WNW), but the combined swell energy climbs into the moderate range (620 to 652 on the 20th). It’s marginal, but it’s the best the forecast has to offer.

So I’ll call the 20th of September (Sunday) as the standout. Morning has clean light onshore wind, waist-high sets with that longer period, and energy building. Afternoon holds similar, maybe a touch more kick. It’s barely a surf day, but after all that flatness, it’s the only window to get wet. This break is consistent, so if there’s something, it’ll be rideable, but expect crowds – they’re often here.

The 21st and 22nd of September stay in the marginal zone with light winds and small SW swell, then it fades back to poor conditions to finish out the outlook.

Bottom line: big gap of nothing, then a very small window around the 20th. Otherwise, leave the stick at home.

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.
