The Lowdown
G’day, Rusty here. We’ve only got one spot on the radar for this outlook, and that’s Johanna. It’s a beach and point setup, very consistent, exposed to the south, and it’s an intermediate level break. The water temp is sitting at 58°F, which is pretty much bang on average for this time of year, nothing unusual there.
The next week and a bit is a mixed bag, with some proper size rolling through but the wind not playing nice for a lot of it. Let’s run through it.
Monday the 10th kicks off with a solid 10ft SW groundswell (period 18 seconds), but it’s blown out with a southerly wind straight onshore. The combined energy is strong at 6593, but it’s a write-off for paddling. That onshore wind and big swell will make it a mess. Monday afternoon is worse, don’t even bother.
Tuesday the 11th sees the swell drop a touch to 10ft from the WSW, period 14 seconds, and the wind swings to a cross-offshore from the NNW. That’s cleaner, but still a lot of water moving around. The energy drops to 3318, but it’s still a hefty session for intermediates.
Wednesday the 12th is a no-go. The swell pumps up to 15ft from the WSW with a 16-second period, but it’s cross-onshore and gusty. Energy is massive at 10099 – that’s a beast, but it’s just a washing machine.
Thursday the 13th morning is a bit of a tease. Swell is 16ft from the SW, 16 seconds, energy 12695 – huge. But the wind is cross-shore, making it lumpy and hard to manage. Not one for the faint-hearted.
Friday the 14th morning has a monster 18ft SW swell (17 seconds, energy 16764), but it’s cross-onshore and the forecast says it’s actually too big for this break. That’s expert territory and even then, messy.
Now, here’s where it gets interesting. Sunday the 16th morning is a standout. The swell drops to a more manageable 10ft from the SW (14 seconds), but the wind goes glassy from the east – 3 mph. That’s a rare combo for Johanna. The energy is 3898, moderate but punchy, and conditions are described as excellent for experienced surfers. The waves will be clean, lined up, and with that long period groundswell, it’ll be peeling nicely off the point. This is your best bet in the first week. Crowds are often here, so expect some company.
The following week, from Monday the 17th onward, things settle down. The swell drops to the 5ft to 8ft range, with clean offshore winds from the east and north-northeast. Tuesday the 18th is another gem: 7ft from the WSW, period 14 seconds, and glassy conditions in the afternoon. Energy is 2919, moderate, and it’s clean. The 19th and 20th keep that trend with clean offshore winds and smaller swell, but it’s more of a fun, longboard-style wave.
The real standout in the second week is Saturday the 22nd afternoon. Swell builds to 13ft from the WSW (14 seconds), with a moderate offshore wind from the north. Energy jumps to 7337 – strong – and conditions are described as exceptional for expert surfers. That’s a big, powerful groundswell with offshore wind. It’s a long-range call, so less certain, but if it comes together, it’ll be pumping.
Sunday the 23rd morning is also huge: 15ft from the SW, 16 seconds, energy 10273, with a light east-northeast cross-offshore. That’s another expert-only day, but the combo of size and clean wind is rare.
To sum it up: the standout session is Sunday the 16th morning for that glassy, clean 10ft SW swell – it’ll be the best of the first week. For the second week, keep an eye on Saturday the 22nd afternoon for a potential epic, but it’s a long way out. The rest of the time, you’ve got smaller clean days midweek that’ll be fun but not firing.
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.
