The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for Blackies.

To be straight with you, we've got a long, lean stretch ahead. For the next week and a half, it’s small and messy. The swell just won’t get its act together, and the wind keeps pushing in from the wrong directions, so we're looking at a lot of poor surf conditions and marginal days. The combined energy readings are weak, with values below 400 for the first ten days, and mostly below 300, so there’s just not much oomph in the water.

Now, the water temp is sitting at a balmy 72°F with an anomaly of 5°F, which is much warmer than normal for this time of year. That’s a nice surprise if you’re just having a paddle, but it won’t help the surf.

We’ve got a real dry spell until we finally see a pulse of energy on Saturday the 29th of August. That’s the only standout in this whole outlook. On Saturday morning, we see a jump in the swell, with a combined energy reading of 931, which is moderate wave energy, bumping up to 942 in the afternoon. The swell is 4ft from the SSW, with a period of 18 seconds. That’s a nice, long-period groundswell, which will bring some better shape and power, but this is a beach and point setup. With the period that long, it might break a bit straight at the beach, so the point section could be the place to be. The wind is light and onshore in the afternoon, so it’ll be a bit bumpy but manageable.

The next day, Sunday the 30th, holds similar size and shape, with 4ft swell from the SSW and a period of 16 seconds, and combined energy still up around 882 in the morning and 693 in the afternoon. Again, light winds but cross-onshore, so it won’t be glassy but it’s the best we’ve had in two weeks.

But listen, this isn’t a beginner wave. At over 4ft and with that long period, it’s got some punch. The crowds at Blackies are noted as "often", so you’ll likely have company, but it’s the only game in town.

Before that, from the 17th of August right through to the 26th, it’s a grind. Tiny waves, cross-onshore breezes, and blank days. There is a small window on Wednesday the 26th morning where the wind goes glassy, but the swell is a tiny 2ft with 16-second period from the SW, and combined energy is only 280. You might get a few little runners on a longboard, but it’s marginal.

So the best call is the weekend of the 29th and 30th. It's not epic, but it’s the only real swell on the board. Don’t book a trip around it, but if you’re local and desperate, that’s your window.

Rusty.

Information about the Blackies Surf forecast

The above surf forecast table for Blackies provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Blackies can be found by selecting the local surf guide option on the grey menu. Our Blackies 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 (Blackies) 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 Blackies 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.

Blackies is 1 km (1 miles) from the city of Newport Beach. If you plan a vacation in Orange County, look for hotels and other accommodation in Newport Beach. Newport Beach has rooms for a wide range of budgets as well as car hire and transport links.
