The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks at 4 Mile.
Right off the bat, I gotta be straight with you – it’s not looking like a classic run. We’ve got a long stretch ahead with only a few glimmers of hope, and not a single day that screams "drop everything and go." The best of the bunch is tucked away in the second week.
We start off with a bit of a dud. Thursday the 27th and Friday the 28th are pretty much write-offs. The swell is small, the wind is on it, and the energy is weak to moderate (372 to 651). You’ll be fighting a cross-chop for scraps.
Saturday the 29th morning shows a bit of a pulse – swell picks up to 4ft from the SSW, and the energy gets into the moderate range (1028). Still, the wind is cross-shore and a bit strong, so it’s going to be lumpy. For an advanced crew at a point break, it’s a maybe. Not for beginners, that’s for sure.
The real standout, and I mean the only one really worth circling on the calendar, is Friday the 4th of September. Early that morning, we see a solid 5ft swell from the S, with a period around 11 seconds. The combined energy hits 1102, so there’s proper push behind it. The wind is light from the WNW, making it cross-onshore but gentle. At a point break like 4 Mile, that longer-period groundswell will wrap in nicely. It’s advanced terrain anyway, and with that size, only the experienced crew should be out there. Keep in mind crowds can be a thing here, so you might have some company.
After that pulse, the surf backs off again. The following week has some rideable mornings – like Sunday the 6th with 4ft from the SSW and near glassy conditions at dawn – but the energy is moderate and the quality is marginal. Nothing to get too excited about.
So, bottom line: the next 16 days are mostly a waiting game. If you’re an advanced surfer and you want the best shot at a proper wave, pencil in the morning of Friday the 4th of September. That’s your window.
Rusty.

Information about the 4 Mile Surf forecast
The above surf forecast table for 4 Mile provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 4 Mile can be found by selecting the local surf guide option on the grey menu. Our 4 Mile 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 (4 Mile) 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 4 Mile 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.
