The Lowdown

G’day, Rusty here. Let’s cut to it: the next couple weeks look pretty bleak for a proper surf. We’ve got a run of small, chopped-up, cross-shore junk coming, with hardly a window of clean conditions. It’s a real dry spell, so don’t get your hopes up.

Starting this Friday morning at 4 Mile, there’s a little energy in the water – moderate combined energy at 379 – with a 2ft SSW swell rolling in at a long 15 seconds. But the wind’s cross-on from the west at 6 mph, putting a few ripples on it. It’s marginal at best. The water temp is about average for this time of year. Friday afternoon the wind picks up and goes cross-shore, and the surf just dies.

The weekend is more of the same. Saturday morning has a bit more size at 3ft, but it’s choppy with a cross-on breeze. Sunday’s no better. The whole stretch from Friday through Monday morning is basically a write-off – poor conditions, cross-shore winds, and lumpy, messy waves. If you’re a kite surfer, this might look better than for paddle surfing, but for us, it’s a no-go.

Tuesday the 18th offers a tiny glimmer – still only 3ft to 3ft, with the energy up a bit to 660, but the wind stays cross-shore and the waves are still messy. Not worth getting wet for. The pattern holds: small SSW swells, but the wind just won’t give us a break.

Heading into the next week, the swell direction shifts to the northwest, but the period drops right off to a short, weak 8 seconds. This is windswell, not groundswell. The energy picks up a little on the 19th (870), with 5ft on offer, but it’s short-period and cross-shore. A messy combo, not a clean one. This junk continues through the 24th and 25th, with bigger readings up to 6ft, but the quality is still poor. The period stays under 9 seconds, and the wind is relentless.

After that, the swell fades and swings back to the south. There’s a pulse on the 28th – the energy jumps into the strong range at 1237 – with 5ft to 6ft of south swell at a more respectable 14-15 seconds. But again, the wind is up to 19 mph and cross-shore, making it lumpy and hard to handle. This one’s for the experts only, and even then, it’s a struggle. The period is long enough to be proper groundswell, but the wind is going to ruin it.

So, honestly, there is no standout session in the entire 16-day window. The best you can hope for is a few marginal mornings where the tide lines up and the wind is at its lightest, but that’s a stretch. If you’re desperate, Tuesday the 18th morning might be your least terrible option – light breeze, small but cleanish lines – but it’s still only 3ft.

Keep an eye on the charts, but don’t hold your breath. It’s a dry run.

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.
