The Lowdown

Alright, this is Rusty. Let’s be straight with you – the next two weeks around Devonport Rivermouth are looking pretty grim, with only one real moment that might get the heart pumping.

We’ve got a long dry spell ahead. From Monday the 20th of July right through until the end of the month, the surf is just not happening. It’s tiny, weak, and messy. You’ll see a bit of a bump on Wednesday the 22nd – a short-period 5ft NW swell pushing in – but the wind is a cross-shore at 12 mph, and the energy is only moderate (187). It’s a frustrating, choppy mess. The rest of that week is a write-off; we’re talking 1ft dribble with long-period NW groundswell that does nothing for this setup. The water temp is about 56°, which is normal for this time of year, so no surprises there.

The only true standout in this entire run is Monday the 27th of July. That morning, the stars align. We’ve got a solid 7ft NW swell rolling in, with a clean 7-second period, and a light cross-offshore breeze from the WSW at 9 mph. The energy jumps to an impressive 384 (moderate), and conditions look clean. This is a point/river break, so it will handle the swell direction well. The period is short, so it won’t be the most powerful or lined-up wave, but it’ll be rideable and the best you’ll get. The afternoon gets a bit bigger at 8ft, but the wind turns cross-shore and the chop comes in, so stick to the morning. This is a beginner-friendly break, but at 7ft, it’s pushing the limits for a learner – still okay for a confident beginner. Crowds are sometimes an issue here, so expect company.

Beyond that, it’s a washout. The first week of August sees barely a ripple – 0.3ft to 0.7ft swells with clean winds but no wave power. The period is long, but there’s nothing to hold it together. The energy is next to nothing (7-19). It’s a dead zone.

So, clear your schedule for the morning of the 27th of July. That’s your window. The rest of the fortnight is a waiting game.

Rusty.
