The Lowdown
Alright, Rusty here, let’s get into it.
We’ve got a solid 16-day window ahead. The first surf worth paddling out for is Friday the 4th. The week starts with a massive pulse of energy that’s just too unruly for a good session, but by Friday morning, things clean up nicely.
The standout is Johanna. It’s a very consistent, exposed beach and point setup that likes a south swell, and that’s exactly what we’ve got coming. The water temp is sitting at 57°, which is about standard for this time of year, no major surprises there.
Friday morning the 4th, the swell is a solid 18 ft from the WSW, with a very long 16-second period. That’s proper groundswell energy. The wind is a light cross-offshore from the NW, making for clean conditions. The combined energy is massive, at 13422, so you’ll feel the power. This is a big-wave day for experienced surfers only. The period is so long that the point at Johanna should handle it well, but it might be a bit too straight for the beach section. Crowds are often here, so expect some company.
The afternoon holds up similarly, with a 16 ft SW swell, still 16 seconds, and still clean. Best on offer for the experienced crew.
Saturday the 5th sees the wind pick up and the quality drops. We’ve got rain showers and a strong cross-shore, so it’s going to be lumpy. Not worth it.
Sunday the 6th is smaller, around 12 ft, but the wind is still messy. It’s a bit of a write-off.
Monday the 7th is a no-go with onshore winds and a short, weak period.
Tuesday the 8th brings a very long 18-second period from the SW, but the swell is only 7 ft, and the wind is light cross-shore. The energy is moderate at 4806. It’s a picky day, but the glassy windows might offer a clean wave if you’re patient.
Wednesday the 9th is another huge day. The swell is 20 ft from the SW, with a 19-second period, and the combined energy is a staggering 38672. The wind is clean onshore, but the size is too big for this break, even for the experts. It’s a massive, dangerous ocean.
Thursday the 10th is still very big, around 16 ft to 20 ft, with a moderate cross-onshore. Still too heavy for most.
Friday the 11th is smaller, around 10 ft to 12 ft, but the wind is light and mostly clean. It’s okay.
Now, for the real hidden gem. Saturday the 12th. The morning is magic. The swell is 12 ft from the SW, with a 15-second period, and the wind is glassy from the NE. Combined energy is 4751. That’s a clean, lined-up groundswell with no wind. This is excellent for experienced surfers. The afternoon is still clean, with a light cross-offshore. If you want a session that feels pure, this is it.
Sunday the 13th is smaller, around 7 ft, but the wind is strong and cross-offshore, keeping it clean. Not big, but fun.
The second week gets a bit quieter. Monday the 14th and Tuesday the 15th are small, with the wind variable. The best of the lot is Tuesday afternoon the 15th, with a 8 ft WSW swell, a 14-second period, and a light offshore breeze from the NNE. That’s clean and small, with a combined energy of 2414. A nice, mellow session.
Wednesday the 16th has a bit of a bump in size to 12 ft, but the wind is onshore, so it’s messy.
Thursday the 17th is another huge pulse, with a 18 ft SW swell and a 17-second period, but the wind is a screaming onshore at 28 mph. That’s a hard no.
The last day, Friday the 18th, is around 10 ft to 12 ft, with onshore winds. It’s a fade-out.
So, to wrap it up: the best on offer is Friday the 4th for the big, clean groundswell, and Saturday the 12th for the glassy, clean conditions on a solid swell. The 9th and 10th are just too big to be surfable.
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.
