The Lowdown
Alright, it’s Rusty here, and I’m looking at what’s on the table for Johanna over the next couple of weeks. We’ve got a pretty classic setup on the cards – a very consistent, exposed beach and point break that really wants a solid S to SW swell, and we’re getting that in spades. The water is sitting at 58°, which is a touch warmer than normal for the time of year, so that’s a nice little bonus.
The first few days are a write-off, to be honest. Monday the 14th, we’ve got a bit of swell at 5ft from the SW, but the wind is messy and the combined energy is weak to moderate at 899. It’s just marginal, so don’t expect much. Tuesday the 15th gets mean – a big drop in quality as the swell jumps over 15ft with a cross-on gale. That’s 7580 energy of pure lumpy chaos. That’s kite-surf territory, not paddle.
The first real standout window arrives on Wednesday the 16th. Early morning with a clean 16ft SW groundswell, a 15-second period (that’s very long period groundswell, meaning plenty of energy and long waits between sets) and light S winds going onshore. The combined energy is massive at 9805 – strong to very strong. This is expert-only stuff, but the quality looks good. Thursday the 17th drops back to 12ft, but the wind goes cross-on, so it’s a bit choppy. The real magic starts to build again from Friday the 18th. We get clean, cross-off winds from the NW with a 10ft SW swell, 14-second period. Moderate energy at 4282, but clean conditions. This builds nicely into Saturday the 19th morning – that’s your next true highlight. Saturday morning shows a clean 13ft swell from the WSW, 13-second period, NW cross-off wind, and the combined energy is pumping at 8721. That’s the best of the first week. Expect a crowd, though – this spot can get busy when it’s like this.
Sunday the 20th, the wind gets fresh and messy again in the arvo, so stick to the early. Monday the 21st looks promising – a 15ft SW swell with light winds, but the energy is still strong at 5494. Tuesday the 22nd is a serious standout for the second week. We’ve got a crystal-clear morning, a 13ft SW groundswell with a 15-second period, and a clean NNW cross-off breeze. The energy is 6809. And then in the afternoon, it goes glassy – zero wind with an 12ft SW swell. That’s exceptional for the experienced crew. The water’s still that touch warmer than normal, which is nice.
After that, the swell backs off through the 23rd and 24th, but we’re still seeing clean conditions on the 24th morning with a 5ft WSW swell. Then it builds again through the 26th – Saturday the 26th afternoon sees a 10ft SW swell with a 16-second period and gentle cross-on wind, combined energy at 9225. That’s powerful. The very end of the window, Tuesday the 29th morning, looks clean again with a 8ft SW groundswell, 17-second period, and light easterly cross-off winds. That’s another one for the experts to circle – energy at 5456.
So overall, your two true standouts are Saturday morning the 19th and Tuesday the 22nd, with that glassy arvo session being the absolute cream. The rest has plenty of size, but you’ll need to pick the windows with clean wind.
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.
