The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for Noosa - Johnsons.
Right out the gate, the next week is a bit of a grind. The swell’s there through Monday the 17th and Tuesday the 18th, running 7ft to 7ft from the ESE, with a short period around 7 to 8 seconds that makes it look pretty lumpy. The wind is cross-offshore from the SE and ESE, so it’s clean enough but the wave quality is poor with combined swell energy at 486 (moderate). These aren’t the kind of waves you paddle out for thrills.
There’s a real lull from Thursday the 21st onwards through to the end of the month. Thursday morning the 20th drops to 4ft from the SE and energy falls to 267 (moderate), but conditions are still marginal. Friday the 21st morning is the first hint of something better: clean 3ft from the ESE, period 8 seconds, with a light breeze and combined energy at 221 (moderate). It’s surfable but nothing to write home about.
Saturday the 22nd morning is worth a mention for the glassy conditions – absolute dead calm wind from the NNW at 0 km/h – but the swell’s only 4ft from the East, period 7 seconds, so it’s small and weak (energy 132). You’ll find a wave but it’s ordinary.
Now, a true standout sneaks in at the end of the outlook. Saturday the 29th of August morning sees a pulse of swell from the NE at 6ft, period 7 seconds, with cross-offshore wind from the ESE at 20 km/h. Combined swell energy jumps to 535 (moderate), which is the highest in the whole 16 days. That’s your best shot – bigger, clean, and with enough juice for a decent session. Just be aware the period is short, making it a bit crumbly at times. Crowds are often here, so expect company.
For the rest of August and into early September, it’s small and wind-affected. Monday the 31st and Tuesday the 1st of September see easterly cross-shore winds and weak 4ft swell, nothing to get excited about.
Water temp at Johnsons is 68°, which is about 2° colder than average for this time of year – a bit nippy, so bring a spring suit.
Overall, if you want the pick, target Saturday the 29th of August morning. The rest is marginal at best.
Rusty.
