The Lowdown
G’day, it’s Rusty. Let’s talk Wonthaggi. The next week is a frustrating stretch – strong winds and messy surf have the place locked up. The first real glimmer of good conditions doesn’t appear until Thursday the 30th, and the best days are hiding in the first week of August. Here’s the run-down.
Friday the 24th kicks off with a big 12ft SW groundswell, 15-second period, but a 19 mph W wind is blowing straight on it. The combined energy is 6353 (moderate to strong), but the surf is poor. Same story through the weekend: Saturday the 25th has 10ft WSW swell with a 22 mph W wind, and Sunday the 26th drops to 5ft SW swell, still cross-onshore. Nothing worth paddling for.
Monday the 27th and Tuesday the 28th are marginal. Monday sees 6ft WSW swell with a moderate cross-shore wind, and Tuesday gets blown out by a 25 mph NNW wind with 6ft WSW swell. That’s five days of no-go from the 24th to the 29th.
Thursday the 30th is the first clean window. The morning brings a light 6 mph N wind, cross-offshore, and a 5ft SW swell (12-second period). The combined energy is 811 (weak to moderate), but the conditions are clean. Hit the morning – the afternoon turns onshore.
Friday the 31st and Saturday the 1st of August are marginal. Friday has a tiny 3ft SW swell, and Saturday the 1st bumps to 5ft SW swell (17 seconds, very long period) with a gentle cross-shore wind. The energy is 2076 (moderate), but that long period will make it break straight at the beach.
The real standout is Tuesday the 4th of August. The morning is a gem: 6ft SW swell (13 seconds) with a light 6 mph ENE offshore wind, glassy conditions, and the combined energy at 1401 (moderate). The wave comment says “excellent surf conditions for experienced surfers.” The swell direction matches the optimum for Wonthaggi, and the offshore wind keeps it clean. Crowds are “sometimes,” so you might have some company, but it’s the best of the 16 days.
Wednesday the 5th and Thursday the 6th are also excellent. Wednesday morning is glassy with a 5ft SW swell (14 seconds) and a 3 mph N wind. The afternoon bumps to 6ft SW swell (17 seconds) with a light cross-offshore breeze. Thursday the 6th morning has 7ft SW swell (16 seconds) with a 6 mph ENE offshore wind, and the afternoon goes glassy again.
Monday the 3rd of August is a dark horse for experts: the afternoon brings a 10ft WSW swell (16 seconds) with a light 6 mph SW cross-on breeze, and the energy is 4784 (strong). It’s over 8ft, so experts only.
By Friday the 7th and Saturday the 8th, the swell drops to 4ft and 4ft, with cleaner but smaller waves.
The bottom line: suffer through the end of July. Thursday the 30th is a small clean window, but the magic is August 4th, 5th, and 6th. That Tuesday morning is the one to circle. Solid swell, offshore wind, clean conditions. For the experienced surfer, it’s the best on offer.
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.
