The Lowdown
Alright, Rusty here, looking at the outlook for Johanna. This is a spot that knows how to put on a show, but you gotta pick your moments. The water temp is sitting at 57°, which is pretty much what you'd expect for this time of year, no surprises there.
The pattern is a slow build. The early part of the week is a bit of a write-off. Wednesday the 26th is a no-go with that onshore wind messing up a 7ft WSW swell. The energy is there (2424), but the wind is from the wrong direction. We get a bit of a breather on Thursday morning the 27th with a cleaner 4ft swell and a light NW cross-offshore breeze, but it's not exactly firing. The real action starts to cook up towards the end of the week.
Now, let's talk standouts. The absolute jewel in this forecast is Monday the 31st of August. The morning is looking good with a 10ft SW groundswell, and the wind is glassy from the NNW. Then the afternoon session is the real winner. We're looking at an 12ft SW groundswell with a very long 17-second period, and the wind drops to absolutely dead calm. The energy is massive (8626) and it's going to be as clean as it gets. That's the one you want to be in the water for. For the experienced crew, this is pure magic.
The following week has some big numbers, but you have to be careful. Friday the 4th of September sees an 18ft SW groundswell, but the forecast says it's too big for the break. That's a warning for the experts only. The energy is off the charts at 17625, but only if you've got the skills and the balls. The same goes for the 10th of September with a 20ft plus swell, that's for the big-wave chargers only.
For Thursday the 3rd of September, the morning looks promising with an 12ft SW groundswell and a clean NNW cross-offshore, but the wind is a bit stiff at 16 mph. The afternoon gets messy.
So, to sum it up: the mid-week is a warm-up, but Monday the 31st of August is the clear standout. Get on it if you can. The following week is all about big, dangerous waves. The crowds are a known thing here, so expect some company on the peak.
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.
