The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the table for Devonport Rivermouth over the next couple of weeks.
Straight up, the outlook is a bit of a bummer. We're looking at a long, dry spell with pretty much nothing worth paddling out for. The first real chance of a wave doesn't show up until Wednesday, August 3rd, and even then, it's a real mixed bag. The whole first week is basically a write-off, with a few days of tiny, weak swell and poor conditions.
The standout moment, if you can call it that, is the morning of Wednesday, August 3rd. We've got a 5ft swell from the NNW, and while it's a short period of 7 seconds, it's the biggest we see. The wind is a light WSW cross-off, which will keep the surface clean. The combined wave energy is moderate at 217. It's a Rivermouth, so it's a point and river setup, and a 5ft wave is pushing it for beginners. It's surfable, but the conditions are just very ordinary. The afternoon sees a bit more size at 5ft, but the wind goes cross, and the score is even worse.
The only other time you might even think about it is the afternoon of Saturday, August 8th. There's a 4ft swell from the NW with a tiny 5-second period, and the wind goes glassy. The energy is weak at 96, so it's small and weak, but at least it's clean. Consistency is an issue here anyway, as this spot is inconsistent.
The water temp is about average for the time of year. For the rest of the forecast, it's all small, weak, or blown out. The period from July 29th through to August 13th is punctuated by a few days of small, weak swell, but mostly it's a waiting game. The forecast can change, but for now, this is a lean run.
Rusty.
