The Lowdown
Alright, Rusty here, let’s chew through what’s happening at Johanna for the next couple of weeks. The first few days are where the gold is – a couple of days that’ll have everyone talking. The second half gets ugly, so we’ll hit it while it’s hot.
Thursday the 30th is a total dud – cross-on wind, choppy, and 10ft of junky swell. Not worth your time. Water’s at 58°, which is about normal for this time of year.
Friday the 31st turns the corner. Morning brings a clean 7ft SW groundswell with a light offshore breeze. The period is 12 seconds, so it’s got shape. Combined energy is moderate (1498). It’s a proper clean session for the experienced crew. Afternoon gets a bit cross-on, so the morning is the go.
Now, Saturday the 1st of August is a true standout. Morning is already pumping: 8ft SW groundswell, period pushing 17 seconds – that’s very long period groundswell, so expect power and long, clean lines. Winds are light and offshore. Energy is strong at 3597. Then the afternoon goes ballistic: 10ft SW, 17 seconds, glassy with offshore breeze. Energy hits 5495. This is exceptional, expert-only level. Johanna will be handling that SW swell beautifully. Crowds are often here, so get there early. This is the best day of the whole window.
Sunday the 2nd still has size at 10ft, but wind picks up to 15 mph offshore, period drops a touch. Still clean but trickier for the average surfer.
Monday the 3rd goes nasty – fresh cross-shore winds, period plummets to 9 seconds, and by afternoon it’s 18ft of lumpy cross-onshore chaos with 9452 energy. That’s kite-surfing territory. Steer clear.
Tuesday the 4th through Wednesday the 5th are poor to marginal – onshore wind, messy chop, swell between 6ft and 8ft but no quality.
But Thursday the 6th afternoon is another absolute gem. Morning still has a slight cross-shore chop, but by afternoon the wind goes glassy – dead calm. Swell is 12ft from the WSW at 15 seconds, energy is 7922 – very strong. This is exceptional for experts. Glassy conditions on a long-period groundswell at Johanna is pure magic.
Friday the 7th morning stays glassy with a light easterly – 12ft SW, 14 seconds, 5302 energy. Clean and powerful. Afternoon gets a bit of ripple.
Saturday the 8th and Sunday the 9th see offshore winds again, with 7ft to 8ft SW groundswell, periods 14-16 seconds. Clean, moderate energy, good for experienced surfers. Sunday afternoon the wind gets stronger.
Monday the 10th is promising early – 12ft WSW, 14 seconds, clean with moderate offshore wind, energy 5282. Afternoon gets wrecked by strong cross-shore wind.
From Tuesday the 11th to Friday the 14th, it’s mostly a write-off. Cross-shore and cross-on winds, lumpy, poor. Friday the 14th afternoon has a massive 12ft SW swell with a 21-second period, but it’s cross-on and choppy. What a waste.
So the bottom line: Saturday the 1st of August and Thursday the 6th of August are the two absolute must-surf days – big, clean, glassy or offshore, long period, world-class potential at Johanna. Don’t sleep on them.
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.
