Alright folks, Rusty here. Let’s have a look at what’s coming down the line for Johanna. This is a classic, exposed west coast setup, and it’s going to be a tale of two weeks. The first half is all about size and power, but the wind is going to be a fight. The real hero window is a few days in, and then a second pulse of serious groundswell shows up right at the end of the run.

Right off the bat, Monday the 13th of July is a monster. We’re looking at a solid 23-foot swell from the WSW, with a very long 16-second period. The combined energy reading is a massive 23865, which is some serious deep-ocean punch. The water temp is sitting at 60°, which is about 2° warmer than average for this time of year, so it’s not a total ice bath. But here’s the catch – the wind is howling from the WNW at 25 mph, creating a messy cross-shore chop. It’s just too big and too blown out for a paddle. This setup looks way more interesting for kite surfing than for a traditional surfboard.

Tuesday the 14th stays big, with 18-foot swell, but the wind is still a strong cross-onshore, making it a write-off. Wednesday and Thursday the 15th and 16th drop a little, with 12-foot to 13-foot swell, but still that cross-onshore wind keeps the surface lumpy, and the scores are low. It’s a tough stretch.

Then, Friday the 17th of July is the first standout. The swell holds at 12 feet from the SW with a very long 16-second period, but the game-changer is the wind. We get a light cross-offshore breeze from the NNW. That’s the ticket. The water will be clean. Now, at 12 feet, this is expert territory only. That long period groundswell will be a freight train, and it’s going to be breaking heavy. It’s perfect for the point and reef sections, but the beach break will be a straight close-out. It’s a proper, heavy day for the experienced crew.

Saturday the 18th and Sunday the 19th are still good, but the size backs off to 8 feet and then 5 feet. The wind stays light and offshore, so the waves will be clean. These are better for the intermediate surfer, especially Sunday morning with that 5-foot swell and clean conditions.

The following week from Monday the 20th to Wednesday the 22nd offers consistent, clean conditions with that light offshore flow, and swell sizes in the 5-foot to 8-foot range. These are fun, manageable waves, but nothing mind-blowing.

Now, look out for Friday the 24th of July. Another big pulse of SW groundswell arrives, pushing 10 feet with a very long 18-second period. The combined energy jumps back up to 6083. The wind is light from the NW, so it’s going to be glassy clean. This is another day for experts only. The period is so long that the sets will be massive and peaky, and you’ll need to be in the right spot.

The final weekend, the 26th and 27th, sees the swell drop and then pulse again, but the wind starts to pick up a bit, and the consistency fades.

So, the two real standouts are Friday the 17th of July and Friday the 24th of July. Both are big, powerful, long-period SW groundswells with clean, light winds. If you’re an expert, those are your days. The in-between is clean but smaller, perfect for a cruiser session.

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.
