The Lowdown

G’day, I’m Rusty. Let’s check out what’s cookin’ at 4 Mile, a proper advanced point break that loves W swell. The water’s 58°F, which is right around average for this time of year. To be honest, the next week or so is a bit of a bummer. We’re stuck in a rut with tiny, weak swells and cross-onshore winds most days – not much to get excited about.

Right now, on Wednesday the 5th, there’s barely a ripple—just 1ft of weak SW swell with a short 14-second period. The wind’s cross-onshore and the combined energy is a measly 142 – too small to bother suiting up. That keeps going through Thursday the 6th and into the 7th, with the same tiny stuff and poor conditions. Friday morning shows a jump in period to 19 seconds but still only 1ft from the SSW – energy bumps to 237 but it’s marginal with the cross-onshore breeze.

The weekend ain’t much better. Saturday the 8th stays small and weak, but by Sunday the 9th we finally see the swell push to 5ft in the morning and 6ft in the afternoon, coming from WNW with a short 9-second period. Combined energy climbs to 673 in the morning and a solid 1087 by the arvo – that’s moderate to strong. But the wind turns cross-shore with a moderate breeze, and it’s only ranked as marginal. The swell direction (WNW) isn’t ideal for this spot which prefers a W groundswell, so the lines won’t be perfect.

Monday the 10th sees the swell drop back to 4ft, with a 10-second period from the WNW. The morning glass-off is the real highlight – light SSW winds and clean conditions, with moderate energy at 509. There’s shape in the water, but the cross-onshore breeze returns by the afternoon. Crowds are likely at this break, so expect a few heads in the water.

The real standout in this whole forecast is the morning of Sunday the 16th. After a long stretch of flat nothing, we get glassy, clean conditions from the SSW with a solid 3ft of groundswell at a very long 16-second period. Combined energy is 517 – moderate, but the wind’s nearly dead still. That long-period groundswell and the light winds at a point break like 4 Mile will give you clean, well-formed waves. The offshore wind direction is nailed on from the SSW, and the swell points right where you want it. That’s your session to circle on the calendar.

From Monday the 17th onward, the winds pick up again and the energy fades, so the tail end of the window is pretty forgettable. If you’re willing to wait, that Sunday 16th morning is the only real prize of the fortnight.

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.
