The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s on the cards for the coming weeks.
The standout here is Johanna, a beach and point setup that's very consistent and exposed to the south swell. The water temp is sitting at 58°, which is about average for this time of year, so no surprises there.
We kick off Friday afternoon, July 31st, with a 7ft SW swell at 12 seconds. It’s a bit of a messy one with cross-on wind, so while there’s energy in the water (1542 combined energy), it’s not going to be a classic. Saturday morning, August 1st, is where the magic starts to happen. The swell jumps to 8ft from the SW, the period stretches out to a very long 17 seconds, and the wind goes glassy cross-off. That’s clean, powerful groundswell. The energy is massive (3597). Saturday afternoon is even bigger, hitting 10ft from the SW with the same long period and clean glassy wind. This is proper expert territory now, over 8ft, and with a period over 15 seconds, it’s going to be a freight train. This is the best on offer for the first week.
Sunday the 2nd holds the same size, 10ft, but the wind picks up to a moderate breeze. It’s still cross-off and clean, but those stronger winds will take the shine off. The energy is still huge (4518 – 4150). Monday the 3rd is a write-off thanks to rain and fresh cross-on wind. The rest of the week into the 5th and 6th of August sees the swell drop back to 4ft – 6ft, but with light offshore winds, those smaller days will be clean and fun for the intermediate crew.
Now, hold on to your board. The real standout of the whole forecast lands on the 14th and 15th of August. Friday morning, August 14th, we’re looking at a 15ft swell from the W with a gentle cross-off breeze. The energy is off the charts (7344). That’s only for experts. But the absolute gem is Saturday morning, August 15th. A 16ft swell from the WSW, 14-second period, and light cross-off wind. The combined energy is a staggering 13822. This is as good as it gets for the big wave crew. The afternoon is similar, 16ft at 15 seconds, but with a light cross-shore wind. It’s still epic, but that morning window is the one.
The stretch from August 10th to 12th sees some huge swell, 18ft, but with strong cross-on winds, it’s going to be a messy, dangerous beast. That’s more of a kite surfing show than a paddle session.
So, to sum it up: the best windows are Saturday morning, August 1st, for a solid, clean groundswell, and the absolute standout is Saturday morning, August 15th, for the big wave chargers. That’s the one you circle on the calendar.
Rusty, signing out.

Information about the Johanna Surf forecast
The above surf forecast table for Johanna provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Johanna can be found by selecting the local surf guide option on the grey menu. Our Johanna 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 (Johanna) 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 Johanna 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.
Johanna is 93 km (58 miles) from the city of Warrnambool. If you plan a holiday in Far West of Victoria, look for hotels and other accommodation in Warrnambool. Warrnambool has rooms for a wide range of budgets as well as car hire and transport links.
