The Lowdown
G’day, this is Rusty.
We’ve got a mixed bag coming up at Johanna. The water temp is sitting at 58°, which is pretty normal for this time of year. The first few days are a write-off thanks to poor wind and lumpy conditions, but there’s a real standout shaping up for the end of the first week.
The real gem is Friday morning, August 7th. We’ve got a 8 ft swell from the WSW, with a nice long 16-second period pushing in. The wind is light offshore from the north, and the wave energy is pumping at 5148. Conditions are clean, and the break is very consistent. This is exceptional surf for experienced surfers, but at 8 ft, it’s only for the crew who know what they’re doing. The afternoon goes glassy with a 5 km/h NE breeze – perfect for a late session.
Before that, Thursday morning, August 6th, offers a smaller, cleaner option with 6 ft from the WSW, a 16-second period, and a cross-off breeze from the NW. It’s a solid 4 out of 10 and clean, but nothing like the Friday session.
The weekend of August 8th stays rideable, with 8 ft swell and offshore winds Saturday morning, but the wind picks up in the afternoon, and by Sunday it’s all blown out with rain and cross-onshore winds.
The second week kicks off with a massive pulse. Monday August 10th sees a 21 ft swell from the WSW with a 16-second period and insane energy over 21,000. That’s too big for Johanna, even for the experts. It’s the same story through Tuesday, with 18 ft and 16 ft swells. Not for paddle surfing – this is kite territory if anything.
Things settle down by Wednesday and Thursday, but the wind and chop make it marginal. Then, Friday August 14th morning is another standout: 16 ft from the SW, 13 seconds, clean with a light cross-off from the NW, and energy at 9776. This is exceptional for experts only. The afternoon gets even bigger at 23 ft, but that’s just too much.
Saturday August 15th morning is still big and clean at 18 ft with a 17-second period, but it’s only for the real hardcore. Sunday August 16th is a beauty – 12 ft in the morning with a long 18-second swell, clean, and then a glassy 15 ft afternoon with 18-second period. Both are exceptional for experienced surfers.
That Friday the 14th morning and Sunday the 16th afternoon are your best bets in the second week, but remember, those long-range forecasts are promising, not locked in.

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.
