The Lowdown
Alright, Rusty here, let’s break down the next couple of weeks.
Right off the bat, it’s a rough start. We’ve got a massive, powerful swell hitting Johanna, but the wind is junk. For the first few days, it’s mostly cross-onshore or cross, with a fresh breeze making it lumpy and choppy. The swell is proper – 16ft to 18ft from the SW, with periods up to 15 seconds, and the energy is massive. But honestly, it’s a washing machine. Not a good time to paddle out. The water temp is about 58°, which is pretty normal for this time of year.
There’s a window on Monday the 27th and Tuesday the 28th of July. The wind backs off and turns cross-off, cleaning things up. The swell drops a bit, but we’re still looking at clean 8ft to 13ft waves. The energy is still potent. Tuesday morning the 28th is the standout of this first week – clean, 13ft SW groundswell with a 16-second period, and a fresh cross-off breeze. That’s a proper session for the experienced crew. The period is long, so expect long lulls, but when they come, they’ll be well-shaped lines.
Then we hit a bit of a lull around the end of July. Not a lot to write home about until the start of August.
Now, the real highlight is August 1st and 2nd. Saturday the 1st of August is looking like the best of the whole run. The wind is light onshore from the SW, with an 18ft SW swell at 16 seconds. The energy is huge. This is a big swell, over 8ft, so it’s experts only. Expect a few people out there for this one. The water temp is still around 58°, which is average.
Sunday the 2nd of August is still pumping with a 13ft SW swell at 16 seconds, but the wind is a bit more cross-onshore, so Saturday is the clear winner.
The following week, August 3rd to 5th, keeps the swell going. Monday the 3rd has a 15ft SW swell with a very long 18-second period, but the wind is cross-onshore. Tuesday the 4th and Wednesday the 5th are looking incredible. Tuesday morning has a 10ft SW groundswell at 16 seconds with a light cross-off from the NE. That’s clean, powerful, and manageable for strong intermediates. Wednesday morning the 5th is a bit smaller, 5ft SW, but with a glassy offshore from the NNE. That’s a rare, clean, offshore day at Johanna.
The last days of the forecast, August 7th, see a resurgence of size with an 8ft SW swell at 18 seconds and a fresh offshore from the NNE. That’s a powerful, clean, and fast wave.
So, the absolute standout is Saturday the 1st of August. That’s the big one – 18ft, 16-second, clean, light wind, huge energy. If you’re an expert, that’s your day. The second best is Tuesday morning the 4th of August, for a slightly smaller, cleaner session.
There’s a lot of swell, but the wind is a trickster. Pick your windows carefully.

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.
