The Lowdown
Alright, Rusty here again. Let’s break this one down in feet and Fahrenheit.
Honestly, it’s a slow start for Blackies. We’ve got a real dry spell before anything worthwhile shows up. The first chance to get wet is Wednesday morning, August 26th, but it’s not much to brag about. Expect waves around 4 to 4ft from the S, with a cross-onshore breeze that’s going to wrinkle the surface. The water is sitting at a weird 73°F, which is a full 6°F warmer than normal – it’s like someone turned the thermostat up.
From there, the swell hangs around but the quality doesn’t improve. Thursday the 27th and Friday the 28th bring small 2 to 3ft SSW swell, but the wind stays cross-onshore. Even the long-period groundswell on Friday – 17 to 19 seconds – can’t save a session with no size and rippled surface.
The one bright spot in the first week? Saturday morning, August 29th. That’s your play. You’ve got solid 3ft SSW swell, a 17-second period, and light offshore wind from the WSW. The energy is strong, and it’ll be clean. This is the best of a pretty average bunch. After that, it’s mostly waist-high junk for the next week.
Then, September 9th, Wednesday afternoon, a bigger 5ft S swell shows up with 16-second period and massive energy—this is a real pulse of power. But the wind is going to be a moderate cross-onshore at 20 km/h, which will chop it up. It’s a classic “good swell, bad wind” scenario.
So here’s the take: Saturday August 29th is your best bet for clean, rideable waves. Everything else is patience and hoping the wind shifts.
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.
