The Lowdown
Alright folks, Rusty here. Grab a coffee, this one’s a bit of a mixed bag. We're looking at a long run ahead for 4 Mile, a classic advanced point. First things first, the water’s sitting at a comfortable 61°, which is a touch warmer than usual for this time of year – a nice little bonus.
Right now, we're in a bit of a lull. The first week or so is looking pretty average. The swell energy is moderate, but the cross-winds are making a mess of things. There’s a touch of size on Monday the 14th and Tuesday the 15th, with 5ft from the WNW, but the wind is cross-on, so it's more of a messy, lumpy proposition than anything clean. You'd be better off waiting for the next tide.
The real standout, the one that makes me sit up straight in my chair, is Tuesday the 22nd of September. It’s a long way off, so lock it in with a pinch of salt, but the models are showing some serious promise. We've got a clean 5ft of swell from the WNW, and the wind forecast is absolutely glassy in the morning. That's a rare treat for this stretch, meaning the point should be running smooth, with long, peeling lines. The swell energy is ramping up, and with the wind going glass, this is the pick of the entire forecast.
Following that, Wednesday the 23rd sees the swell bump up to a meaty 6ft from the WNW, with a 12-second period – that’s some proper groundswell energy. This is going to be a powerful wave, but it's getting a bit on the bigger side, and with a cross-shore wind, it won't have that same clean, perfect look as Tuesday morning. This one is firmly for the advanced crew only.
After that, the swell fades back down to the 3-4ft range, with periods around 11 seconds through Thursday the 24th. It's a drop-off in quality, but you might find a sneaky one if you’re desperate.
So, to wrap it up: the first week is a write-off. A few days with marginal conditions, but nothing to get excited about. The big one to circle on the calendar is the morning of Tuesday, 22nd September. That's your best chance for clean, waist-to-chest high lines with no wind. If that holds, it'll be well worth the wait. Wednesday the 23rd has the power for the experts, but the wind isn't as kind.
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.
