The Lowdown
Righto, let’s have a look at what’s on the table for Wonthaggi over the next couple of weeks. It’s a bit of a mixed bag, to be honest. The swell energy is there at times, but wind and size are gonna make it a tricky stretch. The water temp is sittin’ around 56°, which is pretty much average for this time of year, so no surprises there, just your usual crisp Victorian winter-into-spring feel.
First up, the early week has got some size, but the conditions are rough. Tuesday the 1st is a write-off with a fresh cross-breeze and lumpy, chunky surf. Wednesday the 2nd is still messy with a cross-onshore flow, though the swell is a solid 7ft to 7ft from the WSW with a long 16-second period – loads of energy (2285 and 2271 in the tank) – but it’s just not clean enough to get excited about. That Thursday the 3rd is a no-go: onshore gales and 12ft to 13ft of raw, blown-out swell. Not for paddling.
We hit a bit of a window come Sunday the 6th. Morning brings a 10ft WSW swell with a 14-second period (3234 energy), and a light NW cross-breeze. It’s still a bit lumpy, but the afternoon cleans up nicely: 8ft from the WSW, 14 seconds (2336 energy), with a light S cross-breeze. That’s the first real chance of the period – not perfect, but rideable and with plenty of grunt.
Now, the standout is sitting on Monday the 7th and Tuesday the 8th. Monday morning: 4ft WSW swell, 12-second period (only 484 energy, so not a lot of push), but the wind is light and cross-offshore from the north, giving you clean conditions. Monday afternoon is even better: 3ft, 13-second period, and a light offshore from the NE – dead clean. That’s the pick for a longboard or a fun mid-length. Tuesday the 8th morning steps it up: 5ft, 13-second period (1642 energy), with a light cross-offshore breeze again. Clean, lined-up waves, ideal for experienced surfers. That morning window is the best on offer.
Later on Sunday the 13th we get another glassy moment – morning has 4ft from the WSW, 14-second period, dead glassy with a light SSW air. Super clean but small. Then Monday the 14th morning brings 6ft from the SW with a 16-second period (1875 energy) and a light cross-offshore breeze – that’s a solid, clean groundswell session for those who know the bank.
After that, it fades into onshore slop and windswell. Nothing worth chasing from the 15th onward – just lumpy, onshore, and uninviting.
So, the real highlights are Monday the 7th through Tuesday the 8th morning, and then Sunday the 13th and Monday the 14th morning. The Tuesday the 8th morning is the one to circle – clean, sweet 5ft, long-period SW groundswell, light wind. That’s a session you’ll remember.

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.
