Devonport Rivermouth Surf Forecast and Surf Report

Right then. Let’s have a look at what’s cookin’. To be straight up with you, for the next 16 days, Devonport Rivermouth (Devonport-Rivermouth) is looking like a pretty flat and tough stretch. The swell just isn’t showing up with any real punch for a proper paddle.

We kick off from Friday, 28 August. There’s a tiny bit of swell. It’s a very long-period NW groundswell coming through at 18 seconds, but the height is only 1 ft. The water temp is 55°, and a 0.7° anomaly means it’s just about normal for the time of year. The wind is a clean cross-off, but with that tiny size, you’d be fighting for any ride. The wave energy feels weak (128). Honestly, it’s pretty poor.

That same pattern hangs around through the weekend and into the start of next week. Saturday brings even less, with 1.0 ft in the morning and then a super short 5-second period windswell in the afternoon mixing things up in a messy way. The energy drops way down, like 36 on Saturday morning.

We get a little bump on Tuesday afternoon, 1 September, with 6 ft of NW windswell, but the period is short at 6 seconds and it’s blown out by a fresh breeze of 25 km/h NNW. The energy climbs to 306, so there’s water moving, but the quality is poor for a surfboard. Honestly, with that combo of strong wind and short-period chop, this setup looks more interesting for kite surfing than paddle surfing.

Thursday, 3 September, is similar – a 6 ft NW swell with a 6-second period and 35 km/h winds. Messy.

Then we get the biggest and most energetic swell of the whole outlook. Friday morning, 4 September, shows 8 ft from the WNW with a 7-second period. The combined wave energy jumps to 595. The wind is a clean cross-off from the west at 25 km/h. That 8 ft is getting up there, and for a beginner that’s too much – this is for more experienced surfers. By the afternoon, we’ve got 7 ft and even more energy at 652. This is the best on offer for the whole 16-day run. If you’re an expert, this Friday window is the standout. The swell direction (WNW) is a bit off the optimum NW, but the size and clean wind make it worth a look, just before it gets too messy.

After Friday, it starts to drop. Saturday, 5 September, is onshore and choppy. Sunday morning, the 6th, has 8 ft from the NNW with a 9-second period and clean cross-off wind – that’s a big wave with 934 of energy, but it’s a beast for experts only.

From Monday, 7 September, through to the end of the second week, it fades away again. We see long-period NW groundswells, but they are tiny – like 2 ft on Monday morning, dropping to 0.7 ft later. The wind stays clean most of the time, but there’s just nothing to ride. The forecast confidence for that second week is low; it looks flat.

So, to wrap it up: the one true standout is the Friday, 4 September, with solid 7-8 ft WNW swell and clean offshore winds. For the rest, it’s a long wait with a lot of flat spells. It’s just one of those runs where a bit of patience is needed.
