The Lowdown

Alright, Rogues, Rusty here. We’ve got a big ol’ window of surf ahead, but it’s not all gonna be easy pickings. This stretch starts with a solid pulse of south-west swell, but the wind is gonna be a pain in the arse for a few days. The water temp is sittin’ about 58°, which is pretty much spot on for the time of year, no real surprises there.
Monday the 27th kicks things off with a decent 8ft south-west swell, period around 13 seconds, and a cross-off wind from the NNW at 9 mph. The wave energy is strong (1915), and conditions are clean. This is a solid go for experienced surfers, but it’s no beginner wave at this size.
Tuesday the 28th gets a bit wild. The swell hangs in at 8ft, but the wind cranks up to 22 mph from the NNW, still cross-off, but it’s gonna be a handful. The energy jumps to a massive 5028, but by the afternoon a shift to a westerly cross-on at 22 mph with rain makes it a write-off. The swell also jumps to 16ft, which is just too big for most.
Wednesday the 29th is a washout. A massive 21ft south-west swell with a 16-second period hits, but it’s got a strong south-west cross-on wind at 19 mph. The energy is off the charts (18989), but it’s way too big for paddling and the wind is trash. This is more of a kite surfing show than a surf session.
Thursday the 30th sees the swell drop a bit, but still 10ft in the morning with a cross-on wind. It’s not pretty. The afternoon clears up a little with 8ft and a lighter cross-on, but it’s still just marginal.
Now, Friday the 31st is where it starts to get interesting. The swell drops to 7ft from the south-west, period 12 seconds, and the wind goes light north-west at 6 mph, which is a clean cross-off. The energy is moderate (1475). This is a solid window for the experienced crew.
Saturday the 1st of August is the absolute standout. The swell is 8ft in the morning, but it’s the afternoon that’s a dream. The wind goes light from the NNW, clean cross-off, and the swell jumps to 10ft with a very long 18-second period from the south-west. The energy is pumping (6200), and the conditions are clean. This is the best on offer, a proper power session for the experts. The crowds are often around here, so you’ll have company for these waves.
Sunday the 2nd starts clean with a 12ft swell and a north-west cross-off, but the wind picks up and the afternoon is a write-off with rain and a westerly cross-on.
Monday the 3rd is a bit of a mixed bag. The swell is still 13ft, but the wind is light, so it’s marginal but clean.
Tuesday the 4th brings a nice 8ft south-west swell and a glassy afternoon with the wind dying off to nothing. That’s a beauty.
Wednesday the 5th of August is another absolute standout. The morning has a 12ft south-west swell with an 18-second period, and a light offshore from the north-east. The energy is very strong (7295). The afternoon goes glassy. This is a top-tier session, but it’s for experts only.
The rest of the week into the 9th and 10th sees a messy pattern with a big westerly swell and onshore winds, which is nothing to get excited about. The 11th is a quiet end, with a smaller 8ft swell and cross-shore winds.
So, to sum it up: the best windows are the afternoon of Saturday the 1st of August and the morning of Wednesday the 5th of August. Both are clean, powerful, and for the experienced surfer. Everything else is either too big, too windy, or just average.
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.
