Johanna Surf Forecast and Surf Report

G’day, Rusty here, lookin’ at the forecast for Johanna.

Right off the bat, we’ve got a mix of solid swell and tricky winds, so you’ve gotta pick your moments. The water temp is sittin’ around 57°, which is pretty much spot on for this time of year – nothin' crazy there.

We kick off on Friday, August 21st with a lumpy 7ft WSW swell, but a 12 mph cross-shore wind is gonna mess it up. That swell energy is readin' 3398 (moderate to strong), but it’s not clean. Saturday the 22nd is a write-off – a big 16ft swell but hammered by 16 mph onshore winds, way too raw and messy to even think about it.

Now, Sunday the 23rd is where it starts gettin’ interesting. The morning looks bloody good – clean, with a 12ft SW swell and a light 9 mph offshore wind. That’s a proper groundswell with a 14-second period, powerin' in. This is expert territory though – 12ft is for the crew who know what they’re doin’. Monday the 24th stays clean, with 8ft SW swell and light offshores – solid for experienced surfers, and the energy is still decent at 2686 (moderate).

Tuesday the 25th morning is a standout. Glassy conditions with a 10ft SW swell, 13-second period, and 3 mph wind – that’s as clean as it gets. The combined energy is 4095 (moderate to strong), and the wave comment says it’s excellent for experienced surfers. This is the best on offer in the first week.

Things get a bit average Wednesday the 26th with onshore gunk, but Thursday the 27th afternoon brings a funny one – a 3ft swell but with a 21-second period! That’s a very long-period groundswell, which at Johanna (a beach and point setup) might wrap in nicely and offer some clean lines. Just be aware, long period swells can be a bit straight at beach breaks, but the point there should help. That afternoon is clean with a light offshore.

Friday the 28th is another cracker – the morning has a 12ft WSW swell with a 17-second period and a clean 12 mph offshore wind. That’s a sensational session for experts, with energy at 6628 (strong). The afternoon stays clean with 10ft. Then Saturday the 29th morning is still clean and 8ft – good fun for experienced surfers.

There’s a bit of a lull from Sunday the 30th through Monday the 31st with messy cross-shore winds and moderate swell, so not worth paddlin’ out unless you’re desperate.

Then, lookin’ at Tuesday, September 1st: the morning is glassy with a 12ft SW swell, 16-second period, and energy at 5069 (strong). That’s an exceptional session for experts – clean, powerful, and long-period. That’s the second true standout of the whole window.

Wednesday September 2nd stays clean through the day, with 8ft SW swell and glassy conditions in the afternoon. Thursday the 3rd has a clean 12ft but with a shorter 8-second period, so it’ll be a bit less formed. From Friday the 4th onward, the winds turn ugly again, with 19 mph cross-onshore spoiling things and only a brief clean-up on Saturday the 5th with a 10ft SW swell.

In the second week, the picks are clear: Tuesday September 1st morning is the standout, maybe Saturday September 5th afternoon for a clean session if you’re keen.

Remember, Johanna is very consistent, but it’s exposed and can get big fast – keep an eye on those 12ft+ days, that’s expert-only territory. And crowds are often there, so you might have to share the peak.

Rusty.
