The Lowdown

Alright, mates, Rusty here. Let’s have a look at what’s coming down the pipe for Johanna.

Right off the bat, the first few days are a write-off. Saturday the 5th has a solid 16 ft swell from the WSW, but it’s coming with a nasty 22 mph cross wind and a risk of thunderstorms. The water’s sitting at 57°, which is pretty much bang on for this time of year, so nothing weird there. The combined energy is a massive 10883 – that’s serious power – but it’s all for nothing with those conditions. It’s a total mess.

We do get a bit of a breather on Sunday morning, the 6th. The swell drops to 10 ft from the SW with a 14-second period, and the wind goes light and cross. It’s still a bit lumpy, but a lot more doable. The energy is still high at 4689. It’s not perfect, but it’s the first real chance to get wet if you’re desperate.

The middle of the week is a real mixed bag. Monday the 7th is choppy, Tuesday the 8th has a decent 7 ft SW swell with a very long 18-second period – that’s a proper groundswell – but the wind is cross and the energy is 4359. It’ll be cleanish but those long-period waves can be a bit tricky, breaking straight and fat at a beach break. Not the best.

Now, here’s the standout. Forget the rest of the week, because Wednesday the 9th and Thursday the 10th are absolutely pumping but way too big. We’re talking 16 ft to 20 ft SW swells with periods of 16-18 seconds. The energy readings are off the charts – 25579 and 20981. That’s for experts only. The wind is cross-onshore, so it’s not even that clean. It’s a monster, but it’s a messy one.

The real highlight, the one you need to circle, is Saturday the 12th. The swell drops to a solid 12 ft from the SW with a 16-second period, and the wind goes completely glassy in the afternoon. Zero wind. Energy is 4223, so it’s got heaps of power. That’s as good as it gets for Johanna – clean, long-period lines. It’s a bit heavy for beginners at that size, but for the experienced crew, it’s a dream. The morning’s also excellent with a light cross-offshore breeze.

After that, things ease off. Sunday the 13th is a bit smaller and wind becomes a factor again. Monday the 14th morning has a nice 5 ft SW swell with a light cross-offshore breeze and energy of 1224 – clean and fun for the intermediate crowd. But the afternoon turns into a mess with a 19 mph onshore wind.

The second week gets a bit weird. Tuesday the 15th and Wednesday the 16th see a bump back up to 15 ft, but the wind is onshore or cross, making it choppy and ugly. Then, look out for Thursday the 17th. That’s another potential cracker. The morning is glassy, with a 15 ft SW groundswell at 16 seconds and an energy of 10606. That’s a big, powerful, clean swell for experts. The afternoon stays clean with a light cross-offshore.

The last weekend, the 20th, brings another massive pulse – 16 ft from the WSW with a very long 19-second period and energy of 17059. But again, the wind is cross and it’s just too big for the break to handle well. It’ll be a washing machine.

So, the best on offer? Saturday the 12th is the clear winner for a proper, clean, powerful session. If you’re an expert and hungry for size, Thursday the 17th morning is your second chance, but it’s a week and a half out, so keep an eye on it. The rest of the window is either too big, too windy, or just average.

Stay safe out there.

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.
