The Lowdown
Alright, folks, Rusty here. Let's chew the fat on what's coming up for the local breaks.
It's gonna be a quiet few weeks, with a lot of flat, blown-out days. The first real chance of a wave doesn't show up until the very end of the forecast.
For the first week, from August 18th through to the 29th, it's a total dead zone. Swell is tiny, between 1ft and 3ft, and the wind is mostly cross-onshore or onshore, making everything choppy and ragged. No quality surf to be found. Don't bother.
The only standout – and I mean the *only* one – is the morning of Saturday, August 29th at Blackies. This is a beach and point break that's inconsistent, but when it has a pulse, it can be fun. On that morning, we're looking at a 3ft SSW swell with a long 16-second period, packing some real grunt (combined energy of 473). The wind is light and variable from the SW, which means clean, offshore conditions. The water is a warm 71°, which is much warmer than usual for this time of year, so you'll be comfortable in a spring suit. That long period will give the waves some shape and power, but it might make them a bit straight at a beach break. Still, for a small, clean morning session, it's your best bet.
The next morning, Sunday, August 30th, looks similar with a 3ft SSW swell and a 15-second period, also with light offshore wind. It's a solid backup.
So, the call is clear: the first 11 days are a total flat spell. Your only real window of opportunity is that Saturday the 29th and Sunday the 30th. It's a long way off, so don't bet the house on it, but it's the only light at the end of the tunnel.
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.
