The Lowdown
G’day, it’s Rusty. Let’s talk Johanna in feet and miles.
Water temp is about 57°, nothing out of the ordinary for the season. First surf worth a look comes Saturday August 29th: 8ft WSW swell with a 14-second period, but cross-on wind at 15 km/h makes it choppy. Not your day.
Sunday the 30th bumps to 10ft SW, 13 seconds – still cross-on. Monday the 31st gets a bit cleaner with a light cross-shore breeze at 10 km/h, 10ft SW, 14-15 seconds. Marginal.
Tuesday September 1st morning: 10ft SW, 16-second period, clean cross-offshore NNW wind at 30 km/h. Energy reading 3853 – solid. For the experienced only.
The standout window opens Thursday September 3rd: 15ft WSW, 14 seconds, cross-shore wind, energy 7944 – huge and raw. Friday September 4th morning is the real gem: 13ft SW, 15-second period, clean cross-offshore NNW at 25 km/h, energy 7540. Crowds are likely but this is the best of the bunch.
Saturday the 5th turns ugly: 16ft SW, 35 km/h cross-on wind, energy 13171 – lumpy mess. Sunday the 6th cleans up: 16-18ft WSW, 13 seconds, cross-offshore NNW wind, energy up to 9441. Big but clean.
Monday September 7th sees 23ft WSW with a 15-second period, energy 22963 – too big for Johanna unless you’re a madman. Tuesday drops to 16ft SW but still messy. Thursday the 10th offers 20ft SW, 16 seconds, clean cross-offshore wind – still too big for most.
Friday September 11th morning is a nice drop: 11ft SW, 15 seconds, clean offshore wind at 30 km/h, energy 5508. Good for strong surfers. Saturday September 12th morning – 8ft SW, 14 seconds, gentle cross-offshore wind, energy 4495 – clean and much more manageable. That’s the pick for the second week.
Best of the whole run: Friday September 4th morning. 13ft SW, 15-second period, clean offshore wind, heaps of juice. Second best – Saturday September 12th morning for a clean, fun size.
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.
