The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks. The good news is there’s surf on the horizon, but you’re going to need some patience. The first week is a write-off, with nothing worth paddling out for until we get well into the second week. It’s a classic case of waiting out the junky conditions.

We’re looking at 4 Mile, a point break that handles a west swell nicely. Water temp is sitting at 61°F, which is *a touch warmer than normal* for this time of year – not a huge shift, but nice if you’re in a spring suit.

For the first few days, from September 13th right through to the 26th, it’s pretty grim. The wind is all over the place, mostly cross or cross-onshore, and the wave heights are small – mostly 2 ft to 5 ft. The swell energy is mostly moderate, but the quality is shot. You’ve got a lot of “poor surf conditions” and “marginal” forecasts. It’s not worth getting wet. There’s a solid two-week gap of nothing worthwhile here.

Things finally start to look up on the morning of Sunday, September 27th. That’s the standout. The wind goes glassy – dead calm – with a 4 ft swell from the WNW. The period is a short 8 seconds, so it’s windswell, not groundswell, but with glassy conditions, it’ll be clean and fun for the advanced crew. The combined energy is moderate (413). For a point break, that short period isn't ideal but the clean surface makes it rideable.

After that, the afternoon kicks up a bit more size to 5 ft from the NW, but the wind swings back cross-shore and the energy jumps (792), which is moderate. It’ll be lumpy. The following Monday (28th) has some potential with light cross-onshore winds and 5 ft to 5 ft swells, but the conditions are marginal. It’s not the same quality as that Sunday morning glass-off.

So if you’re hanging for a wave, mark your calendar for Sunday the 27th morning. That’s the one clean window in an otherwise quiet 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.
