The Lowdown
Alright folks, Rusty here. Let’s break it down. We’ve got one spot on the radar for the next couple of weeks, and it’s a proper big-wave setup.
The main event is Johanna, a beach and point break that’s exposed to the south swell. It’s a very consistent spot, so when the energy shows up, it shows up in a big way. The water temp is sitting at 57°F which is about average for this time of year, so nothing to shock you when you get out of the wetsuit.
We kick off this Sunday, the 23rd of August, with a serious pulse. Sunday morning is looking like a standout for the big dogs. The swell is 12ft from the SW, and the period is a beefy 14 seconds – that’s proper groundswell. The combined energy is massive at 6142, so you’ll feel the ocean breathing. The wind is a clean cross-off from the NNW, keeping the faces tidy. This is expert territory only, as the size is well over 8ft. If you’re not comfortable in heavy water, give it a miss. Sunday afternoon gets a bit blown with a light cross-on, so morning is the clear call.
Monday, the 24th, and Tuesday, the 25th, settle down a bit. Monday morning is 8ft from the SW with that same 14-second period, again cross-off wind. Still a solid size for experienced surfers. Tuesday morning is the real gem of the early week – glassy conditions with the NNE wind dropping to 3 mph, and a 8ft SW swell. That’s clean, smooth, and lined up. Crowds are often at Johanna, so expect company for these cleaner sessions.
The wind turns ugly from Wednesday the 26th through to the end of the week, with strong cross-onshore conditions. The swell remains in the 8ft range, but the quality drops off. It’s onshore and choppy, so not worth paddling out. The next big window opens up on Monday the 31st of August. The wind swings back to an offshore NW direction, holding 12ft swells from the SW with a 16-second period. That’s a long-period groundswell, which at a point break setup like this, will offer some beautiful, long walls. The energy is still strong at 6449.
The real standout, though, is further out. Friday the 4th of September is looking like the absolute best of the whole forecast. The afternoon session is a solid 15ft from the SW, 16-second period, with a light offshore breeze from the NW. The combined energy is 8955, and the conditions are being described as exceptional for experts. This is the one to circle on the calendar. It’s a long way out, so the certainty isn’t locked in, but if it comes together, it’ll be a session to remember.
The weekend of the 5th and 6th holds some size, but the wind is a bit all over the shop. Sunday the 6th of September has a nice clean cross-off from the ENE, with a 8ft WSW swell – that’s a more manageable size for a strong intermediate. Into the second week, the pattern continues with big swells and tricky winds. Monday the 7th of September gets messy with strong onshore winds, so that’s a write-off.
Overall, the best bets are Sunday morning the 23rd of August for the heavy crew, Tuesday morning the 25th for the glassy conditions, and the big long-range standouts on Friday the 4th of September. The rest of the window is a mix of big energy and challenging wind, so pick your moments.
This is Rusty, signing off.

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.
