The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s heading our way for the next couple of weeks at 4 Mile. I'll be straight with you—it’s not a classic run of waves, but there are a few windows worth setting the alarm for.

The first few days are a bit of a write-off for clean surfing. We’re looking at some cross-shore winds and a cross-chop that’s just going to mess things up. The swell is coming from the SSW with a period around 14 to 16 seconds, which is a proper groundswell, but the energy is moderate (519-774) and the wind just isn’t playing ball. The water temp is sitting at 59°F, which is about normal for this time of year, so nothing unusual there.

The first real chance of a decent surf comes on Saturday, 1 August. The morning swell jumps up to 6 ft, but it’s swinging around to the NW with a short period of only 8 seconds. That’s a windswell, and it doesn’t have the grunt of a groundswell. The real issue is that the wind is still cross-shore, so it’s going to be a bit bumpy. The energy is moderate (753). Not a total loss, but don’t expect perfection.

Sunday, 2 August morning is a bit of a wildcard. The swell holds at 6 ft from the WNW with a period of 9 seconds. The wind is a light cross-onshore at 6 mph, so it’s not glassy, but it’s the best looking window in this first week. The energy is moderate (705). It’s a point break here, so that cross-onshore wind might actually set up a bit of a wall. It’s advanced-level surf, and it’s fairly consistent, so the crowd factor is a concern – it’s often busy here. The swell is coming from the WNW, which is a good direction for this spot.

Monday, 3 August morning has a similar 6 ft swell from the WNW with a 10-second period, but the wind is a light offshore from the SSW at 3 mph. That’s a major positive. Clean faces. The energy is moderate (773). This is the standout of the whole forecast period. It’s a point break, so that long period swell (10 seconds) will wrap in nicely. The only downside is that it’s still a marginal call in the data, but for a Monday morning, you could do a lot worse.

After that, the swell drops off and the wind turns more onshore. From Tuesday, 5 August onwards, the swell gets smaller and the conditions get more marginal. There’s a long gap of small, choppy surf until the end of the second week.

The second week looks pretty weak overall. There’s a bit of a pulse from the SSW on Thursday, 13 August with a 3 ft swell and a 16-second period, but again the wind is messy. The energy is moderate (553). It’s just not enough to get excited about. The whole period from 5 August to 14 August is a long stretch of poor or marginal conditions.

So, to wrap it up: the best bet is Monday, 3 August morning at 4 Mile. Light offshore wind, solid 6 ft groundswell from the WNW. It’s a point break, so it’ll handle it well. Get there early if you can. The Saturday and Sunday before are also worth a paddle, but the wind is the factor.

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.
