The Lowdown

Alright, this is Rusty coming to you live from the coast.

We’ve got a proper run of swell on the way for Johanna, but it’s gonna take a bit of patience to get into the good stuff. The early part of the week is messy, but by the time we hit the end of the month and roll into August, there are some serious windows opening up for the experienced crew.

The Early Grind (Sunday 26th through Tuesday 28th)

The surf is already up at Johanna on Sunday afternoon, with a solid 8ft swell out of the SW, but that W wind at 9 mph is putting a cross-on chop on it. It’s a bit of a mess, and the combined energy is high at 1389, but the quality just isn’t there. The best you can say is it's a workout. Monday morning cleans up nicely with a clean NNW cross-off breeze. That same 7ft SW swell looks a lot better, and the water temp is sitting at 58°F, which is pretty average for this time of year, so nothing wild there.

Tuesday morning is a big step up. We’ve got an 12ft swell from the W, the wind is cross-off from the NNW at 19 mph, and the wave energy is pumping at 5387. This is clean, powerful, and only for those who know what they’re doing. The afternoon, though, goes to shit. That same swell drops to 10ft, but the wind swings W at 22 mph and brings a lumpy, cross-on mess. Hard pass on Tuesday afternoon.

The Heaving Core (Wednesday 29th to Friday 31st)

Wednesday morning is the big one. We’re looking at a 20ft SW swell with a 15-second period. The wind is howling onshore from the SSW at 19 mph, but it’s an *onshore* direction, so the break might be holding. The combined energy is a massive 15443. This is not for the faint of heart or anyone on a foamie. This is expert territory only, and even then, you’re taking your life in your hands. Wednesday afternoon is blown out again, and Thursday stays messy with strong cross-on winds. Friday is smaller but still a bit lumpy and choppy from the WSW breeze.

The Gold: Saturday August 1st to Sunday August 2nd

Here’s where we cash in. Saturday morning brings a clean 4ft SW swell with a 17-second period and a light N breeze. It’s clean, but the real standout is Saturday afternoon. It’s *glassy*. Zero wind. The 7ft SW swell is running with a 16-second period, and the combined energy is 2502. This is a proper, clean, lined-up groundswell. For experienced surfers, this is the session of the window.

Sunday follows it up with a strong 10ft WSW swell and offshore N winds both morning and afternoon. The energy is in the 4000s, and it is going to be clean, thick, and barreling. This is another top-tier day for the crew who can handle it.

The Long-Range Promise (August 3rd to August 10th)

The first week of August has plenty of size, but the wind is fickle. Monday August 3rd is big and clean in the morning, but the afternoon gets lumpy cross-shore. After a couple of blown-out days on the 4th, Wednesday the 5th looks interesting with a 13ft SW swell and onshore wind, but the energy is massive again (8444).

The real long-range standout is Monday August 10th. We’re looking at a 7ft to 8ft SW swell with a period of 19 to 21 seconds—that’s extremely long period groundswell. The wind is offshore from the NE at 9 mph, and the combined energy hits 12352 in the afternoon. This is an exceptional forecast for expert surfers. The sets will be few and far between with that period, but the waves will be perfect, clean, and racy. It’s a long way out, but it’s a date to circle on the calendar.

So, bottom line: the first few days are a battle. Forget the mid-week mayhem. The absolute best is Saturday afternoon (August 1st) for the glassy, clean conditions, and if you can wait, Monday August 10th is looking like a proper session for the experts.

Stay safe out there.

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.
