The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s cookin’ for the next couple of weeks down at Devonport Rivermouth (point/river).
Right off the bat, I gotta be straight with you – this is a tough run. The whole 16-day window is pretty much a write-off for decent waves. We’ve got a long stretch of poor surf conditions stretchin’ from the first day right through to the second week. The only time the surf gets a mention is around the 4th of September, and even then it’s just a marginal call with questionable tide conditions.
The first real standout, if you can call it that, is Friday the 4th of September, morning. The swell is 5 ft out of the NW with a period of 7 seconds, combined energy of 275 (moderate). The wind is WSW at 12 mph, giving us a cross-off breeze that’ll keep things clean. Still, it’s only a 1 out of 10 grade, so nothin’ to get too excited about. The water temp is about 55° – that’s pretty normal for this time of year, nothin’ wild.
Now, the big news is what happens on the 7th and 8th of September. The swell absolutely pumps up – we’re talkin’ 11 ft to 16 ft waves, with a period of 8 to 9 seconds and combined energy goin’ through the roof – 1699 to 4271, that’s strong to very strong. But here’s the catch: those waves are way too big for this break. It’s not a paddle situation; it’s more like a kite-surfing setup if you’re into that. The wind is offshore and cross-off, which is mint, but the size is for experts only.
So, bottom line: don’t hold your breath for epic surf. The 4th of September morning is the only window where you might get a few clean, small waves, but it’s inconsistent and you’ll be dodging the crowds. After that, it’s too big or too messy. The rest of the 16 days are just a blank run, which is pretty normal for this area when the conditions don’t line up.
Stay patient, mates. The ocean will turn around eventually.
