The Lowdown

Alright, grab a coffee and let's have a look at what's coming down the pipe for Johanna.

The next 16 days are a bit of a mixed bag, but there are a couple of serious standouts for those who know their way around a big wave. We've got a bit of a wait on our hands, but the payoff looks huge.

First up, we've got a solid pulse of swell running. The ocean has some serious energy, with the combined energy readings hitting four and even five-digit figures, meaning there's plenty of juice out there. For Tuesday the 25th of August, Johanna is firing early with a clean 8ft SW groundswell (13-second period) and glassy conditions. The water temperature is sitting at 57°, which is pretty normal for this time of year. The problem is, that sweet morning window is the only real highlight for a few days as the wind turns cross-onshore and messes things up through Wednesday and Thursday. It's still surfable, but not the best.

Then hold onto your hats. Friday the 28th morning shows a big 12ft SSW swell, but it's blown out by a strong onshore wind, so it's not ideal. Hang in there though.

The real standout is Sunday the 30th afternoon. We've got a massive 13ft SW groundswell with a very long period of 19 seconds and the combined swell energy is pumping at (11345). That's a powerful, clean ocean. The wind is light and cross-onshore, so it won't be perfect glass, but it's manageable. This is a serious swell for experienced surfers only—well over the 8ft mark. Keep in mind, with that long period, it's going to offer up some super clean, powerful lines but the sets will be spaced out.

Another top pick is Monday the 31st morning. Still plenty of size at 12ft from the SW (16-second period) with a nice cross-offshore breeze, making for clean conditions. The energy is still massive (6965). Again, this is for the crew who can handle it.

Looking further ahead, the 5th of September Saturday morning is looking excellent for the experienced lot. That's an 12ft SW swell (17-second period) with a clean cross-offshore wind. The combined energy is a monstrous (8124). That'll be a day to remember if the forecast holds.

And finally, the big one to circle on your calendar is Monday the 7th of September morning. Johanna is set to see a 13ft W groundswell with light, clean offshore winds from the NNE. The combined energy is off the charts (9784). The wave comment calls it exceptional for experts, and I can see why. It's a long way out, so don't book your flights yet, but if it comes together, it'll be one of the sessions of the year. Later that afternoon it jumps to 20ft—that is only for the absolute elite, and with a shorter 11-second period, it might be a bit of a washing machine.

The crowds at Johanna can be an issue when it's good, so for those standout days, expect company.

In between these highlights, there are entire stretches where it's either too small, too windy, or simply too big and messy. Don't bother with the 1st of September or the 3rd of September, and the 8th and 9th are just colossal, dangerous walls of water with terrible wind. The 9th is literally too big for the break at over 21ft.

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.
