The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the horizon for Blacks Beach.

Right off the bat, we’ve got a bit of a flat spell to get through. The first few days are looking pretty grim. Tuesday the 1st and Wednesday the 2nd are offering tiny waves, with the swell around 2ft to 3ft, and that’s coming from the SSW. The wind is blowing straight onshore from the WNW, making things messy. The combined energy is weak to moderate (138 to 240), and the forecast really doesn’t give us anything to get excited about. It’s a slow start.

We finally see a little pulse on Thursday the 3rd, but the swell is still only 2ft to 3ft. The period is a long 16 to 18 seconds from the SSW, which is a nice groundswell, but the wind is still onshore, and the energy is moderate (427 to 727). The surf quality is still poor. Friday the 4th and Saturday the 5th are a bit of a tease. The swell bumps up to 3ft to 4ft, still from the SSW with a long period of 16 to 17 seconds. The wind lightens up, going cross-on on Friday and Saturday morning, but it’s still not clean. The energy is moderate (535 to 787). The models are giving these days a marginal rating, so it’s not a total write-off, but it’s not the one.

Sunday the 6th is a write-off with a dropping swell and cross-shore winds. Monday the 7th is another marginal day with the swell back up to 4ft from the SSW, but the wind is light cross-on, so it’s still a bit bumpy.

Now, here’s the standout. Tuesday the 8th of September. This is the one to circle on the calendar. For the morning, we’re looking at a solid 6ft swell from the SSW, with a period of 12 seconds. The combined energy is a strong 1075. But the real magic is the wind. It’s a light, cross-offshore breeze from the SSE. The data says the conditions are "clean." This is rare for Blacks Beach, and when you get that size with clean, cross-offshore wind, it’s going to be firing. The afternoon is still good, with 6ft and fresh cross-offshore wind, but that morning session is the pick. Just be aware that Blacks is an exposed, consistent spot, and with crowds listed as "often", you won’t be alone out there.

After that, the swell fades again. The energy drops back to moderate (477 to 602) from Wednesday the 9th through to the end of the run. The swell sits around 2ft to 3ft, with the wind shifting back onshore or cross-on. The water is about average for the time of year, nothing unusual. The rest of the forecast is a slow, marginal slide into small, onshore slop.

So, the verdict: The first week is a grind. The only real standout is the morning of Tuesday the 8th. That’s your window. Get after it.

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.
