The Lowdown
Alright mates, Rusty here again, but this time in feet and miles for the imperial crew. Let’s talk Johanna over the next couple of weeks. This is an exposed beach and point break that loves a good S to SW groundswell. Water temp is 57°F, about normal for the season, so no surprises there.
First surf worth a look hits Sunday morning, September 13. Swell is 8ft out of the SW with a 15-second period – that’s long period groundswell, packing a punch (2551 energy). Wind from the north at 16 mph, cross-off, so the waves are clean. Solid size, so this one’s for the experienced lot. Sunday afternoon stays similar with 7ft SW, same long period, and lighter NNW wind at 9 mph, still cross-off. Good session.
Monday the 14th drops off. Swell goes to 5ft in the morning, period 13 seconds, and the wind swings WNW 12 mph, getting cross and lumpy. Energy down to 876, weaker but still a wave.
Tuesday the 15th? Forget it. Rain showers, 13-15ft swell, but the wind is a nasty cross-on at 19-22 mph, lumpy and poor. Kite day, not for paddling.
Wednesday the 16th is huge. Swell hits 16ft out of SW, 15-second period, energy at 10226 – very strong. Wind is onshore from the south at 12 mph, so it’s gonna be a messy monster. Only for the experts. Thursday the 17th drops to 11-12ft, but cross-on SW wind at 9 mph keeps it choppy.
Friday the 18th is a standout. Morning has 10ft SW swell with a 14-second period, and wind from the NW at 12 mph is cross-off, giving clean waves. Energy is 4360. Not the biggest, but clean as a whistle. Saturday the 19th holds at 8ft WSW, still cross-off from the NW, glassy in the afternoon at 9 mph.
Sunday the 20th morning is still clean with 11-12ft WSW and a cross-off NW breeze, but the period drops to 11 seconds. Afternoon goes messy with WSW wind at 25 mph – kiter time.
Monday the 21st has 10ft SW, 13-second period, light onshore wind from the SSW at 6 mph in the morning, then cross-on from the SE. Rideable but not pristine.
Now Tuesday the 22nd is the one you circle. Morning brings 11-12ft SW swell with a 15-second period, clean cross-off from NNW at 12 mph. The afternoon? Glassy – barely a breath at 3 mph from the SSW. Swell jumps to 15ft with a 16-second period, energy at 9225, and it looks exceptional for the experts. That’s your session.
Wednesday the 23rd follows up with 13-15ft SW swell, still long period, and clean cross-off winds from NW and NNW. Big and clean. Thursday the 24th drops back to 10ft, and the wind goes messy cross-on from the SE, choppy.
Friday the 25th stays around 11-12ft SW but cross-shore SE wind chops it up. Saturday the 26th morning is light with 8ft SW, a bit weak, but afternoon cleans up with a light N breeze and cross-off, giving clean 8ft – fun.
Sunday the 27th brings 11-12ft SW, very long 17-second period, energy 7344, but cross-shore wind makes it lumpy. Monday the 28th finishes with 15ft SW, long period, huge energy up to 9510, but wind is either cross-on or cross-shore.
Rusty, signing off.

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.
