The Lowdown
G’day, I’m Rusty. Let’s get into it.
Alright, Jo, we’re looking at a solid 16-day window, but it’s a bit of a slow burn at first. The first real chance to get a wave will be on Tuesday afternoon, September 1st, but honestly, it’s not great. The water’s sitting at 57°, which is pretty much normal for this time of year – nothing to worry about there.
The first standout is going to be Johanna this Thursday morning, September 3rd. But hold your horses – it’s big. We’re talking a 18 ft groundswell from the WSW with a period of 14 seconds, and the combined energy is pumping hard at 11,351 (moderate wave energy). The wind is a cross-on at 22 mph, making it lumpy. This is expert territory only, and even then, the conditions are poor. It’s a beach and point setup, so with that much juice and strong wind, it might actually be more interesting for kite surfing than paddle surfing. Skip it.
Friday, September 4th is where it comes together. The morning session sees a 18 ft SW groundswell (16-second period) with a cross-off breeze from the NW at 12 mph. The energy is massive at 14,248 (strong wave energy). The wind is clean, the waves are solid, and this is the pick of the window for experienced surfers. The afternoon holds up too – 16 ft SW, 16 seconds, cross-off from the NNW at 9 mph, with energy at 12,345. It’s clean, consistent, and this is the best on offer.
Sunday, September 6th is a sleeper for the early birds. Morning glass-off with a 13 ft WSW groundswell (14 seconds), light NW breeze at 6 mph, and the energy is 6,152 (moderate wave energy). The conditions are exceptional for expert surfers – clean, long lines, and the point break setup will handle that long period beautifully. The crowds are often here, so expect company.
The second week gets a bit hit and miss. Monday, September 7th is super clean – glassy conditions on the morning with a 6 ft WSW swell (12 seconds), zero wind, and energy at 1,031 (weak wave energy). The afternoon holds a 5 ft swell with a light cross-off from the ENE. Good for a fun cruise.
Tuesday, September 8th morning has a 7 ft WSW groundswell with a very long 18-second period and a light NW breeze. The energy is moderate at 3,354. The point break will love that period, but the beach breaks might be too straight.
Wednesday, September 9th is a monster, but it’s too big. The morning brings a 21 ft SW groundswell (17 seconds) with a 25 mph onshore wind from the SSW. The energy is insane at 22,518 (very strong wave energy). The swell is predicted to be too big for this break – not a paddle session.
Friday, September 11th afternoon sees a 13 ft SW groundswell (16 seconds) with a light onshore breeze from the south at 9 mph. The energy is 7,350 (moderate wave energy). It’s marginal, but the point might offer some cleanish lines.
Saturday, September 12th morning is worth a look – 16 ft SW groundswell with a very long 18-second period, light south wind, and energy at 13,708 (strong wave energy). The point break should handle it well.
Sunday, September 13th morning is glassy with a 10 ft SW groundswell (15 seconds), energy at 4,687 (moderate). Clean and fun for experienced surfers.
Monday, September 14th is a glassy morning again – 8 ft SW groundswell (13 seconds), light NNE breeze, energy at 1,748 (weak). Clean, easy paddling, nice for a session.
The rest of the window into the 16th is messy with cross-onshore winds and choppy conditions. Not worth chasing.
So, if you’re looking for the one, get out there Friday, September 4th – that’s the standout. The Sunday the 6th is a close second if you want a clean, glassy morning session with big, long-period lines.
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.
