The Lowdown
Howdy folks, Rusty here. Let's cut through the noise and look at what the next couple of weeks are serving up for Wonthaggi. It's a wild ride, with some real duds and a couple of windows you'll want to keep clear for.
The first few days are a write-off, plain and simple. Friday the 4th has a big 3-meter groundswell from the WSW, but the cross-onshore wind is gonna have it all chopped up. It's a powerful ocean with strong energy (4963), but it's a mess. Saturday the 5th is more of the same, lumpy and blown out. Sunday the 6th, the wind goes straight onshore while there's still 3-meter swell – that's a full skip. Monday the 7th is weak and short-period, not worth suiting up for. Tuesday the 8th finally sees the wind ease off, but it's still cross-onshore and only about 2 meters. It's there, but it's not inviting.
Then the ocean wakes up with a vengeance. Wednesday the 9th afternoon brings a massive 4-meter swell with rain and strong winds – a big, angry day. Thursday the 10th is a critical one. The swell is a solid 4 meters with an 18-second period, and the energy is very strong (7122). The wind is lighter, and the forecast even says winds and tides are favorable, but this swell is just too big for the break. This is expert-only territory, if anyone's mad enough. The swell backs down a bit on Friday the 11th, to about 2 meters, with lighter winds, but it's still messy.
Now, for the good part. Saturday the 12th is your window. The morning is pure glass, not a breath of wind. You've got a 2-meter southwest groundswell with a 15-second period. The energy is moderate (1075), but the conditions are forecast to be "very good surf." This is the one. The swell direction is perfect, and with those clean conditions, it's going to be the best surf of the week. Sunday and Monday will be rideable but smaller and less clean as the swell fades. The surf really drops out by the 15th, leaving just dribblers and poor conditions.
And then, hold on tight, the giant comes back. The 16th brings building 3-meter swell, but by afternoon it's a messy 5-meter with a short period. Not good. Thursday the 17th is a monster – a 6-meter swell (energy 8431) with strong onshore winds. That's a total washout and more of a kitesurfing day if anything. Friday the 18th is interesting. There's a huge 4-meter south swell with a super long 19-second period (energy 8833), but the wind is light and from the southeast, which gives us a clean, offshore look for the morning. It'll be a powerful, clean, and absolutely barreling day, but it's far too big for this spot. It's a spectacle, not a surfing day. The period finally drops back down over the weekend, with more manageable 2-meter surf and calm winds expected on Saturday the 19th to finish up the run.
Rusty, signing off.

Information about the Wonthaggi Surf forecast
The above surf forecast table for Wonthaggi provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Wonthaggi can be found by selecting the local surf guide option on the grey menu. Our Wonthaggi 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 (Wonthaggi) 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 Wonthaggi 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.
