The Lowdown
G’day, Rusty here.
Look, I’ll be straight with ya – we’ve got a pretty grim run ahead for Wonthaggi. The next week and a half is mostly full of onshore junk, messy wind, and a lot of poor surf conditions. There’s a big gap of nothing worthwhile until we get toward the end of next week. The water temp is sitting about average for this time of year at 57°.
Kicking off on Thursday, 16 July, we finally see a tiny bit of hope. The morning brings a 7ft SW swell with a 15-second period and light WSW winds that are onshore. It’s still marginal, with a combined energy of 1941 (moderate). The afternoon is similar with a 7ft SW swell and light onshore SW winds. Better than a kick in the teeth, but don’t expect anything special.
Friday, 17 July, stays in that marginal zone. Morning has a 6ft SW swell (16-second period) with a cross-shore NNW breeze. Afternoon picks up to 7ft SW with a light cross-onshore WNW wind. The combined energy sits around 1654 to 2113 (moderate). It’s still just okay.
Now, Saturday, 18 July, is one of the two true standouts. Morning brings a clean 6ft WSW swell with a 14-second period and a light cross-offshore N breeze. The afternoon goes glassy with a 5ft WSW swell and a light SE wind. Combined energy drops to 915 (moderate), but those clean conditions will make it worth the paddle. The swell is a bit short-period for a groundswell, but the glassy surface will be a treat.
Sunday, 19 July, is the other standout. Morning is clean again with a 4ft WSW swell (12-second period) and a light cross-offshore N breeze. The afternoon turns glassy with a 3ft WSW swell and no wind at all. Combined energy is low at 444 (weak), but for a small, clean wave, it’ll be a fun session.
After that, it’s back to the doldrums. From Monday, 20 July through to Thursday, 23 July, expect poor surf with rising winds and messy conditions. There’s a bigger 8ft WSW swell on Thursday, 23 July, but it’s cross-onshore and lumpy, so only for the keen or the kooks.
Then we get a bit of a recovery. Friday, 24 July, morning is excellent for experienced surfers with a clean 7ft WSW swell (15-second period) and a light cross-offshore ESE breeze. Combined energy is 1955 (moderate). The afternoon stays marginal but still rideable. Saturday, 25 July, morning is another clean one with a 7ft WSW swell (14-second period) and a light cross-offshore E breeze. Again, the afternoon is a bit more choppy.
The last decent window is Sunday, 26 July, with a clean 5ft SW swell (14-second period) and a light cross-offshore NNE breeze. Then Monday, 27 July, goes glassy with a 5ft to 6ft WSW swell, so that’s a nice little session to end on.
After that, from Tuesday, 28 July, onward, it’s all poor conditions again with strong winds and rain.
So, the best bets are definitely Saturday, 18 July, and Sunday, 19 July, for the clean, glassy conditions. Friday, 24 July, and Saturday, 25 July, mornings are also solid for the bigger, cleaner swell. Keep in mind, the long-period swells (15-16 seconds) can break a bit straight at beach breaks, but Wonthaggi is a fairly exposed spot, so it should still offer some decent lines.
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.
