The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Devonport Rivermouth over the next couple of weeks.

First off, I gotta be straight with you – the next week or so is a bit of a dud. We’re looking at a dry spell with very little on offer. The wave energy is weak, mostly sitting in the double digits (73) at best, and dropping into single digits on some days. The swell is tiny, with a few pulses barely reaching 3ft, coming from the NW, but the period is all over the place – mostly short and choppy, or too long and weak to do anything. Winds are cross or cross-off, but the surf just isn't there. The water temp is sitting at 55°, which is about normal for this time of year, nothing out of the ordinary.

The first real sign of life doesn’t show up until Tuesday, 1st of September. The morning session brings a sudden spike in energy – we’re talkin’ a combined energy of 1284, which is serious power. The swell is showing 12ft from the NW with a period of 8 seconds. Now, that is a lot of water, and for a beginner spot, that’s more than 5ft – it’s gonna be too big for the inexperienced. The wind is a clean cross-off from the WSW, which is a bonus, but that size is only for the experts. The afternoon drops to 6ft, still chunky, but the wind picks up a bit.

The real standout, if you can handle the size, is that Tuesday morning. It’s the only time the forecast really lights up with a decent score and clean conditions. It’s a long way off, so don’t bank on it just yet, but it’s the one to circle on the calendar. After that, the swell backs off and we’re back to small, messy cross-shore junk for the rest of the forecast.

Because this break is a point/river setup, it’s inconsistent and rarely breaks well, so a blank run like this is actually pretty normal for the area. Keep your eyes peeled, but don’t hold your breath.
