The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
We’ve got a bit of a slow start, with nothing worth paddling out for over the first few days. From Thursday the 27th right through to Monday the 1st of September, it’s pretty flat and weak. The few small pulses that roll in are mostly under 3ft, with weak energy readings (down around 38 to 285 in the combined swell energy), and the wind isn’t helping at all—mostly cross-on or offshore but with no real power. It’s a hard pass for a surfer.
Now, things finally start to look up around Wednesday the 2nd of September. That morning at Blacks Beach we get a real turn. The wind drops to glassy – dead calm, just a slight air movement – and the ocean cleans right up. Swell hits 5ft from the SSW, with a period of 12 seconds, and the combined energy jumps to 748 (moderate). The water temp is sitting at 74°F, which is a whopping 6°F above normal for this time of year – that’s very unusual, so don’t expect a full winter wetsuit.
The standout session looks to be the Wednesday morning. It’s not huge, but that glassy surface with a clean 5ft SSW swell will produce some really good, rideable waves at Blacks Beach. This is an exposed spot, and the SSW direction lines up nicely with what this break likes. Crowds can be an issue here often, but early on a Wednesday might give you a bit more room. This is your best bet.
Thursday the 3rd gets bigger, with 7ft swell from the SSW in the morning, but the wind goes cross-on and the combined energy hits 1588 (strong to very strong). That’s a lot of power, and with the onshore angle, it’ll be a messy, challenging day. Better left for the experts only.
By Friday the 4th, the swell backs off to 4ft with a clean offshore wind in the morning, but the energy drops to 964. It’s a marginal call, not a standout.
From the 5th of September onward, it fades again. We see a few days of 3ft to 4ft but with cross-on winds and dropping energy, so it’s back to average or below-average conditions through the second week. A few pulses in the 3ft to 3ft range show up around the 10th and 11th, but nothing that gets the heart racing.
So to wrap it up: the window to watch is Wednesday the 2nd of September, early. That’s your cleanest, best-shaped shot. After that, we’re mostly looking at mediocre conditions for a while.
Stay stoked,
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.
