The Lowdown

G’day, it’s Rusty here. Let’s cut straight to it. The next couple of weeks are going to test your patience if you’re chasing waves around Wonthaggi. There’s a real mix of big, raw energy and long flat spells, and you’ll have to pick your moments carefully.

The main story for this period is a lot of swell, but a lot of it is either too messy, too blown out, or simply too big for this stretch of coast. The water temp is sitting at 56.3°, which is a touch warmer than usual for this time of year – nothing crazy, but you’ll notice it if you’re used to the mid-winter chill.

The first decent window doesn’t show up until Friday the 7th. Before that, it’s a write-off. Monday the 3rd has a lumpy 5.6ft cross-shore mess, and Tuesday the 4th sees a raw 6.9ft to 7.9ft bump with onshore winds – not worth your time. Wednesday and Thursday are small and chopped up, with the swell dropping to under 3ft.

So, Friday morning the 7th: there’s a 4.9ft west-southwest swell with a 16-second period, but the wind is cross-on and it’s a bit choppy. The afternoon is better – the breeze drops to a light 6 mph and the swell cleans up a little. The combined energy is strong at 1576, but it’s still only a marginal call. Saturday the 8th has a similar 4.9ft swell, and the morning looks cleaner with a light cross-offshore wind. It’s inconsistent, so you’ll be waiting between sets, but that long-period groundswell (16 seconds) means some proper lines will come through. It’s not epic, but it’s the best of a slow start.

Now, here’s where things get interesting. Sunday the 9th starts with a howling 28 mph north wind, but it’s cross-offshore and the surf is clean. By the afternoon, the swell jumps to 7.2ft with a 13-second period and the energy is pumping at 2143. The wind eases to 22 mph, still cross-off, and it’s clean – this is a proper stormy session for the experienced crew. The setup is more for confident surfers; the beach break will be handling a lot of water.

Then Monday the 10th is when it gets wild. The swell explodes to a massive 19.7ft with a 16-second period. The combined energy is off the charts at 18410 – that’s some serious ocean. The wind is moderate and cross-on, so it’s going to be a messy, heaving beast. This is way too big for this break. It’s a full-on expert-only situation, and even then, it’s going to be a washing machine. The same goes for Tuesday the 11th with an 11.5ft swell and fresh cross-shore winds. It’s a wall of whitewater, not a surfable wave.

Wednesday the 12th drops a bit to 6.6ft to 8.2ft, but the winds are fresh and onshore, making it lumpy and poor. Thursday the 13th brings another massive pulse – 16.4ft with a 15-second period. The winds are light but cross-on, making it a huge, lumpy mess. Again, this is not a paddle-out situation. This is the kind of day where the beach break is just a closeout bowl of chaos.

Friday the 14th still has a big 11.5ft to 9.8ft swell, with light winds but onshore tendencies. It’s still too big and messy for any real fun. The energy is still very strong, but it’s not doing anyone any favors.

After that big run, things start to settle. Saturday the 15th has a 6.2ft southwest swell with a 16-second period, and the morning looks magic – almost no wind (3 mph) and light cross-shore. It’s clean, and with that long period, there’s some proper push. This is a standout, but it’s inconsistent. The crowd factor is possible so get in early. This is the day to be out there if you can wait it out.

Sunday the 16th is a step back – onshore winds and a 5.2ft swell that’s a little lumpy. Not bad, but not great. Monday the 17th is similar, small and onshore.

The final call for the window is Tuesday the 18th. There’s a 6.6ft to 6.9ft west-southwest swell with an 11-second period, and the wind is light and offshore in the morning. It’s clean and has some energy to it (1780 in the afternoon), but the shorter period means it might be a bit walled up at the beach. Still, it’s a decent way to end the run.

So, what’s the best on offer? It’s a toss-up between Saturday the 8th for a cleaner, more traditional session, and Saturday the 15th when the ocean goes quiet and the long-period groundswell lines up with almost no wind. If you’re up for

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.
