The Lowdown
G’day, Rusty here. We’ve got a wild ride ahead for the next couple of weeks. The action starts this Saturday, August 1st, with a solid pulse of south-west groundswell hitting Johanna. That’s 10 feet of swell with a 17-second period, and the energy is pumping – a reading of 5241. Water temp is 58°F, pretty standard for the season. The wind’s a light cross-off from the NNW at 6 mph, keeping it glassy. Johanna is very consistent, but expect it to be busy – it’s often crowded. This one’s for the experienced crew only.
Sunday the 2nd and Monday the 3rd are a letdown. Sunday still has the size – 10 feet – but the wind picks up and the forecast is marginal, likely tide-affected. Monday gets messy with cross-shore winds and some rain, turning to onshore junk by the afternoon. Skip those.
Tuesday the 4th is poor – windy, choppy, and rainy. Wednesday and Thursday have small, weak swell, around 5 feet, with light but onshore winds, so it’s lumpy. But hold on – Friday morning, August 7th, is looking sweet. The wind drops to nearly nothing, glassy conditions, and we’ve got 8 feet of WSW swell with a 16-second period. Energy’s up at 4573. That’s a clean, powerful morning for experienced surfers. The afternoon gets a bit crossed up, so go early.
Saturday the 8th keeps the quality with moderate north offshore winds, 8 feet of swell, and clean faces. Another good one. Then Sunday the 9th goes flat and sloppy – wind up, swell down to 5 feet, not worth it.
Now, the second week turns serious. Monday the 10th sees a big jump – swell hits 16 feet by the afternoon, with an energy reading of 12492. That’s heavy, powerful water. The wind stays light to moderate and cross-off, keeping it clean, but this is expert territory only. Tuesday the 11th holds that size, and Wednesday the 12th has 15 feet with offshore winds in the morning – clean and grinding. Energy readings are massive, in the 8500 to 14554 range. Thursday the 13th is another huge day – 18 feet of swell, long period, and the energy is off the charts. Friday the 14th starts with 16 feet and clean conditions, but the forecast warns it might be too big for the break – that tells you how heavy it’s getting. The afternoon turns windy and lumpy.
The weekend of the 15th and 16th is messy – Saturday is onshore and choppy, Sunday is blown out with strong winds and rain. That’s kite-surfing weather, not paddle surfing.
So, the best windows are Friday morning the 7th, Saturday the 8th, and the big clean days from Monday the 10th through Friday the 14th. The real standouts are Wednesday the 12th and Thursday the 13th – massive, clean, and powerful. Just remember, this is serious swell – if you’re not confident in heavy waves, watch from the cliffs.
Rusty.

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.
