The Lowdown

Alright, Rusty here. Let's talk about the waves on offer for the next couple of weeks.

Straight up, the outlook for 4 Mile is a bit of a mixed bag. We're looking at a period that starts off pretty slow, with a lot of marginal conditions. The first few days are a write-off for any decent surf, so we'll have to be patient. The water temp is about what you'd expect for this time of year, nothing unusual there.

The first real chance to get a wave comes on Saturday, August 1st. The morning has a 5.6ft swell from the NW, but it's a short period, around 8 seconds, so it'll be a bit weak and won't have much punch. The wind is a cross-shore, which is okay, but the energy is only moderate (759). The afternoon sees a bit of a drop in size and the wind picks up, making it lumpy. Not a standout, but it's the only thing on the menu.

Sunday, August 2nd, is a bit better. The morning has a 5.9ft swell from the WNW, with a slightly longer period of 9 seconds. The wind is light cross-onshore, which is manageable, and the energy is building to a moderate 672. It's still a "marginal" call, but it's the best we've got so far. The afternoon is similar, but the wind picks up a notch.

Monday, August 3rd, is actually the pick of the bunch for the first week. The morning shows a 6.2ft swell from the WNW, with a 10-second period. The wind is light from the SSW, so it's a light cross-onshore, and the energy is strong at 812. It's a solid, fun-sized swell. The afternoon stays similar but with a slightly smaller 4.9ft swell. This is the only window I'd really call a go. The waves will have some shape and push to them.

After that, the surf drops off a cliff. Tuesday through to the end of the second week is a long stretch of small, weak, and often messy conditions. The swell sizes are tiny, mostly under 3ft, and the periods are all over the place. There's a lot of onshore or cross-onshore wind, making for chop and poor surf. We're talking about a gap of pretty much no good surf from the 4th of August right through to the 15th.

There is a slight flicker of hope on the 13th of August, Thursday morning, with a 2.6ft SSW swell and a long 16-second period, with light cross-onshore wind. The energy is moderate (574). But it's a long way out and the size is small. It's a promise, but not one you'd bet the farm on. For a point break, that long period could actually make it a bit too straight, but with light winds, it might offer a clean little wave.

So, to sum it up: the best bet is Monday, August 3rd, with the 6.2ft WNW swell. It's not a world-class day, but it's the only session that has a decent mix of size, power, and okay wind. The rest of the 16-day window is a long wait for very little. Probably a good time to wax the longboard and wait for the next system.

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.
