The Lowdown
Right now, the surf around Four-Mile is pretty grim. We've got a run of weak, short-period slop, and the winds are mostly cross or cross-onshore, which just ruins it. Water temp is about normal for this time of year.
For the first week, you're not missing much. The swell is tiny and weak, and the wind is mostly against us. There are a few pulses of longer-period southern energy, but they're small and the wind just messes things up. It's not until the 23rd that we see some clean conditions, but the swell is still small.
Honestly, the block from the 24th through the 29th is just a wasteland. No size, no energy, just a few days of onshore junk. It's a big gap with nothing on offer.
But there's a light at the end of the tunnel. On the morning of Wednesday the 30th, it finally comes together. We've got 1.5m of WNW swell, a 9-second period, and the wind goes dead glassy. That's the standout window right there. The energy picks up to a moderate 591, so there's a bit of push. It'll be the cleanest, most fun waves we've seen in a while. The next day, Thursday the 1st, the swell backs off a touch to 1.3m, but it's still worth a paddle on the bigger sets. That's your window. After that, it looks like it fades out again.

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.
