The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way down at Wonthaggi.
First up, the water is sitting at 57°, which is a touch warmer than what we'd normally expect for this time of year. Not a game-changer, but you won't be needing the thickest of steamer suits just yet.
Alright, the long-range forecast is a bit of a mixed bag. We've got a solid, long-period SW groundswell rolling in, but the wind is going to be a real pain for the first week or so. The standout window is Saturday, the 12th of September. That morning, we've got a 7ft SW swell (16-second period) with a light cross-offshore breeze, making for clean conditions. The real gem is Saturday afternoon: the swell drops slightly to 6ft, still from the SW, with a 15-second period, and the wind goes glassy. That's the best you're going to get—clean, lined-up waves with moderate energy (1609). It's an advanced break, so it's not for the grommets, but for experienced surfers, that's a proper session.
The Monday after, the 14th, things get messy. The wind swings onshore and kicks up, and by Tuesday the 15th, the swell is pumping 10ft, but it's a washing machine with onshore winds. The energy is high (over 3400 on Tuesday afternoon), but it's a messy, blown-out mess. For a beach break, that's more of a kite-surfing show than a paddle-surfing one.
There's a gap of poor conditions from the 14th right through to the 20th. Then, on Monday the 21st of September, we get a tiny 3ft groundswell, but it's glassy. The energy is weak (448), but if you're desperate for a longboard or a foamie, it's clean. The next real sign of life is Tuesday the 22nd of September morning. A 4ft WSW swell, cross-offshore wind, and clean conditions. The energy is moderate (750), and the period is a solid 13 seconds. It's not a blower, but for a Tuesday morning session, it's a solid little option.
The long-range stuff (the 23rd onward) is all onshore and messy again, or just too small and windy. The 25th of September Friday morning has a 5ft onshore, poor surf. Not worth the drive.
So, bottom line: if you're an advanced surfer, be at Wonthaggi on Saturday the 12th of September. The afternoon glass-off is the pick of the whole 16 days. Everything else is either blown out, too big, or too small. It's a tough stretch, but that one Saturday will make it worth it.
Rusty.

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.
Wonthaggi is 58 km (36 miles) from Cranbourne. If you plan a holiday in East Coast of Victoria, look for hotels and other accommodation in Cranbourne. Cranbourne has rooms for a wide range of budgets as well as car hire and transport links.
