The Lowdown
Alright, surfers, Rusty here. Let’s break down this stretch of open ocean ahead of us. It’s a long-range look, so we're in it for the long haul. The short term is a bit of a tease, but there’s some serious power coming if you’re willing to wait.
We start off slow. Thursday morning at Johanna is small and a little messy, not a priority. Swell builds through the day, and by Friday afternoon things start to get interesting. That Friday afternoon session is the first real taste of quality—a clean 8ft of WSW swell with the wind dropping off to glass. That’s a session worth getting wet for.
Saturday morning is a standout. Offshore wind and a solid 8ft from the WSW. That’s clean, pushy surf that will have the point firing. The water temp is about normal for this time of year, so no surprise.
Then we hit a bit of a lull. Sunday and Monday are a write-off with rain and messy wind. But hold on, because Monday afternoon into Tuesday is where the big show begins. The swell jumps to a 15ft monster from the WSW, and the energy readings are off the charts—11152. But it’s a cross-shore wind, so it’s going to be a battle. This is proper, heavy Johanna. Not for the faint of heart.
Wednesday the 12th is where we have to raise the alarm. The swell is predicted to hit 16ft, and the wind is cross-onshore and lumpy. This is too big and too messy. The energy is huge—15732—but this spot will be a washing machine. Honestly, at this size and wind, the setup looks way more interesting for kite surfing than paddle surfing.
After that big peak, it backs off but it stays powerful into the second week. Thursday the 13th and Friday the 14th are still in the 15ft to 16ft range. Friday morning looks promising with clean 16ft waves from the SW and moderate offshore winds, but the afternoon turns to junk. Expert-only days, no question.
The following week, the swell drops but it’s still solid. The weekend of the 16th and 17th looks fun—10ft on Saturday, dropping to around 8ft by Monday, with light winds. Good, clean, powerful surf for those who want solid waves without the life-threatening size. The 19th sees a fresh pulse of 10ft from the WSW, but the wind is on it. Strong energy, but it’s all about picking the windows.
So, the real standouts here are Saturday morning for that clean, solid push, and Monday the 10th afternoon for the sheer power—if you're an expert. Everything else in that middle section is for the committed few. The last week is promising but less certain; it looks a little more manageable, but keep an eye on the wind.
Keep your wits about you out there. This is heavy water.
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.
