The Lowdown

G’day, Rusty here. Well, we’ve got a bit of a wild ride ahead at Johanna. It’s a beach and point setup, very consistent, exposed to the south swell, and it handles a serious amount of energy. This is not a spot for the faint-hearted when the ocean wakes up.

We kick things off on Tuesday the 11th of August. It’s not perfect, but there’s a heavy 9.8 ft swell from the WSW with a long 14-second period. The combined energy is strong, sitting at 3203. The wind is a cross-off, keeping things clean. Water temp is 57.6°, which is about average for this time of year. This is solid, powerful stuff – experienced surfers will be eating it up, but it’s too big for beginners.

Wednesday the 12th and Thursday the 13th get ugly. The swell builds to a massive 14.8 ft to 16.4 ft from the WSW and SW, with energy readings climbing into the five-digit figures (10624 and 12536). But the problem is the wind – it’s a strong onshore breeze, turning the ocean into a lumpy, choppy mess. Friday the 14th is still messy, with 14.8 ft swell and cross-onshore wind. This is more of a kite surfing show than a paddle session those days.

Saturday the 15th sees the swell ease to 13.1 ft from the SW. The wind finally drops right off, turning offshore in the morning from the SSW. The ocean cleans right up. This is a true standout window. You’ve got a massive, clean SW groundswell with a 15-second period, and the combined energy is still huge at 6599. This is big, powerful, and will be breaking perfectly along the point. Only for experts, but it will be world-class. Sunday the 16th is still very good, with 9.8 ft SW swell, a 14-second period, light cross-shore breeze, and clean lines. The energy is still pumping at 3420.

Monday the 17th and Tuesday the 18th stay excellent. The swell drops to a more manageable 6.6 ft to 7.2 ft from the WSW, period is still long at 14 to 15 seconds. Winds are light cross-off or glassy, meaning the waves will be clean, lined up, and ridable for strong intermediates. Energy is moderate to strong (2037 to 2848). Wednesday the 19th is another fantastic day, with 5.2 ft to 4.9 ft WSW swell, glassy in the morning, perfect for a longboard or a funboard.

After that, there’s a lull. Thursday the 20th through to Monday the 24th of August is pretty quiet – swells drop below 4.9 ft with inconsistent energy. You could still find a wave on the right tide, but it’s not going to fire.

Then, look out for Tuesday the 25th of August. Another big pulse arrives: 8.2 ft SW swell with a very long 18-second period, light cross-off breeze, and clean conditions. The energy is strong at 4444. This will produce clean, powerful lines. It’s a week and a half away, so keep an eye on the forecast, but it’s a promising one for experienced crew. Wednesday the 26th is still solid with a big 9.8 ft WSW swell, but the wind picks up from the north at 15 mph, making it a cross-off – still rideable for the brave, but not as pristine as Tuesday.

Stay safe out there.

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.
