Alright folks, Rusty here. Let's have a look at what's on the cards for Devonport Rivermouth.

Right off the bat, I gotta be straight with you – this stretch of the next 16 days is looking pretty darn flat most of the time. We're looking at a long, quiet spell with barely a ripple to get excited about. The first week or so is dominated by tiny, often less than 1ft, northwest groundswells. The energy is just not there, with combined swell energy figures mostly in the single or low double digits – really weak stuff. The water temp is sitting around 56°F, which is pretty much spot on for this time of year, so no surprises there.

The first real blip of something bigger comes in on Saturday, July 11th, but it's a messy one. A north-northwest windswell pushes up to 5ft in the morning, but the period is a shocking 5 seconds, and the wind is howling from the north at 16 mph. It's a junky, choppy mess. By the afternoon, the swell hits 7ft and the wind goes onshore and even stronger at 19 mph. The energy jumps up (116 to 393), but it's all wind-driven chop. Definitely not one for the paddle board.

Sunday the 12th sees the biggest swell of the whole period – a 8ft to 7ft northwest swell with a bit more period (8 seconds). The combined energy is strong, hitting 754 in the morning and 825 in the afternoon. But again, the wind is a major problem. A strong westerly cross-shore is going to mess it up, leaving messy cross-chop. The afternoon session might clean up a little, but it's still only a marginal call. For the experts only, and even then, it's a battle.

The standouts? Honestly, there aren't many. The best chance for a clean wave is going to be on Friday, July 10th. The swell is still tiny at 1ft, but we get a beautiful, long-period 16 second northwest groundswell and glassy conditions all day. It's a river mouth, so that long period energy might wrap in nicely, but you'll be fighting for scraps on a knee-high wave. It's also inconsistent here, so you'll be waiting.

The other pick is a bit of a wildcard on Sunday, July 19th. The afternoon shows a 5ft lump of short-period swell (5 seconds) under glassy conditions. The energy is moderate (145). The swell is too junky for a point break, but if you're a beginner, that 5ft might be a bit much. It's a very, very average option, but it's the only one with some size and clean conditions in the whole forecast.

Beyond that, it's pretty much flat and clean for the next week, with tiny 0.3ft to 1ft waves. The 24th of July shows a little pulse of windswell, but the period is 4 seconds and the wind is onshore again. Not worth a trip.

So, keep your expectations low. The setups are better for a kite surfer on those bigger, windier days than for a surfer. The river mouth is inconsistent, and it's going to be a lean couple of weeks. Forecasts can change, but as it stands, the 10th of July is your best bet for a clean, tiny glide, and the 19th of July afternoon is a maybe for something a bit more substantial but average.

Rusty.
