The Lowdown

Righto, I’ve had a good look at the charts for the next 16 days and, to be honest, it’s looking pretty grim for 4 Mile. This is a classic point break that usually fires on a solid west swell, but the conditions are just not lining up for any kind of decent session. We’ve got a long stretch of poor surf ahead, with a few days that are only barely worth a mention.

The water temperature is sitting at 58°, which is about normal for this time of year, so no need to reach for the thickest steamer just yet.

Let’s start with this week. It’s a write-off. From Tuesday the 4th right through to Saturday the 8th, the swell is tiny, mostly under 2ft, and the wind is a consistent cross-onshore, which is just going to mess up any chance of a clean wave. The energy is weak, with values barely reaching 249 (weak), and the swell period is mostly short and messy. There’s nothing to get excited about.

Things get a little more interesting heading into the second week. On Sunday the 9th of August, the swell picks up to 4ft from the WNW, with a period of 10 seconds. The combined energy hits 612 (moderate), but the wind is a cross-onshore at 9-12 mph, which is going to create a choppy surface. A few waves might be rideable, but it’s far from clean. The following days, Monday the 10th and Tuesday the 11th, have similar swell sizes (4-5ft) from the WNW, but the energy is still moderate and the wind is again a cross-onshore, so it’s going to be a battle.

The real standout, if you can call it that, pops up on Saturday the 15th of August. The morning looks the best of the whole run. We’ve got a 4ft swell from the SSW, with a long period of 16 seconds – that’s proper groundswell. The wind is light, from the SSW at just 3 mph, which is pretty much glassy. The combined energy jumps to 702 (strong), so there’s some real grunt in the water. This is a point break, and a long period SSW swell like that is going to wrap beautifully around the point, offering some well-shaped, powerful lines. The downside is that with that long period, the sets will be widely spaced, making paddling out a bit easier, but it also means fewer waves. And 4ft is a solid, fun size, not too big for most. This is the best session on offer, by a long way.

After that, Sunday the 16th still has a 3ft swell from the SSW with a 16-second period, and light onshore winds, but it’s not as clean as Saturday. The week after that drops off again, with tiny swells and poor conditions.

So, to sum it up: the next week is a complete dud. The real window is Saturday the 15th of August, with a promising, clean, long-period groundswell that could dish up some long, peeling waves at 4 Mile. It’s still a few weeks out, so keep an eye on the updates, but that’s your best bet. For the rest of it, you’re better off getting the wax off your board.

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.
