The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a mixed bag this fortnight, but don’t give up just yet.
Right off the bat, the first few days are a tough watch. Friday the 4th through Saturday the 5th, we’re looking at tiny, weak swell around 3ft to 3ft from the SSW, but the wind is junk – cross-onshore or onshore – making it bumpy and poor. The water is a balmy 75°F here, which is much warmer than usual for this time of year, almost 8°F above average, so you won’t need a thick suit, but you won’t be catching much either.
Sunday the 6th is the clear standout. Blackies finally wakes up. A solid S swell pushes through, reaching 5ft to 6ft, with a period of 14 seconds. That’s some decent groundswell energy. The combined energy hits 1111 (moderate) on the morning, and the wind goes light and cross-offshore from the east. That’s the clean window. The morning session is the one to aim for – expect very good conditions. Afternoon gets a bit messy with a NW cross-breeze, but the morning is pure. This is your best bet for the whole look ahead.
From Monday the 7th onwards, it’s a slow fade. The swell drops back under 7ft, but the wind shifts to a persistent W or SW cross-onshore, chopping up everything. The rest of the first week and the entire second week look slim. There’s a long, dry spell from Monday the 7th all the way through to Saturday the 19th of September. The swell goes from 6ft down to barely 1ft, and the period becomes inconsistent. The wind just won’t give us a clean break. Even the long-period pulses (17-20 seconds) that show up on the 10th, 14th, and 17th are accompanied by that cross-onshore wind, so they’ll be messy and blown out. The energy drops to weak levels (as low as 140 later on), confirming it’s just not worth paddling out.
Bottom line: Sunday the 6th morning is your only real chance for a clean, fun session. After that, it’s a long wait. The surf will be small and sloppy, and frankly, it looks more interesting for kite surfing than paddle surfing for most of the run. The forecast could change, but right now, it’s a tough stretch.
Stay patient. 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.
