The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
The outlook starts off a bit flat, to be honest. We're looking at a stretch of pretty poor conditions right through the first week. The swell is all coming from the SSW, but the winds are constantly cross-on or onshore, keeping things choppy and messy. The water's a touch warmer than normal for this time of year at 70°, which is a bit unusual, but it won't help the surf quality.
From Thursday the 20th right through to Sunday the 30th, it's a real struggle. The swell is small, mostly between 1ft and 4ft, and the combined wave energy is moderate, ranging from a weak 132 all the way up to a decent 740 (on the 26th morning). But the problem is that even when we get a pulse of energy, the wind is always there to junk it up. It's just not worth paddling out for.
The real glimmer in this whole forecast is the very end of the run. We're looking at Friday the 4th of September. The morning session is the absolute standout. Clear skies, a glassy wind from the SSE at just 3 mph, and a 3ft SSW swell with a very long period of 18 seconds. That's a proper groundswell, and with glassy conditions, it will be as clean as it gets. The combined energy is strong at 652. This is a prime example of a long-period swell that will really favour a point break like Blackies, where the lines will hold up beautifully. It's not too big, so it's good for all levels, but because it's so inconsistent, you'll have to be patient between sets.
The afternoon of the 4th is still okay, with a 4ft SSW swell, 18-second period, and a gentle cross-shore wind, but it won't be as perfect as the morning. The crowds at Blackies are often an issue, so you'll want to be in the water early to get the best of that glassy morning. The long period also means longer gaps between sets, making the paddle out a bit easier.
So, to sum it up: the first two weeks are a write-off. Don't bother. Save your energy for the 4th of September. That Friday morning is the only real standout. It's a bit of a wait, but it could be a cracker.
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.
