The Lowdown
Alright, it’s Rusty here, and I’ve got to be straight with you — this is a tough stretch for Devonport Rivermouth. We’re looking at a pretty quiet run overall with the real action not kicking in until late in the period. The water temp’s at 56°, which is pretty standard for this time of year, so no surprises there.
The first real chance of anything worth paddling out for doesn't show until Tuesday morning, 21 July. That morning we get a tiny push of 3ft NW swell, but with a period of only 5 seconds, it’s weak and won’t have much punch. The combined energy is just 94, so it’s real weak. Winds are light cross-off shore, so it’ll be clean, but the waves are gonna be ordinary — maybe a few fun little ones for a beginner on a longboard. It’s inconsistent here anyway, so don’t expect much.
The next notable window comes Thursday morning, 23 July. Swell jumps to 5ft from the NW, still short period at 6 seconds, and energy climbs to 171 — moderate but not exciting. The wind is a brisk 30 km/h cross-shore from the WNW though, making for lumpy, messy conditions. Not really a paddle session; this setup looks more interesting for kite surfing than paddle surfing, if that’s your thing.
After a bit of a lull, the biggest swell of the forecast shows up on Sunday morning, 26 July. We’re looking at 7ft from the NW with a 7-second period and energy of 370. That’s solidly moderate energy and the biggest surf in the whole outlook. Winds are 12 mph cross-off, so it should be clean. This one’s for experienced crew — anything over 7ft at a river mouth can be a handful. It’s a point / river setup and a long period groundswell would be better on a reef, but this is short-period stuff so it’ll be lumpy. Still, this is the only time in the whole 16 days where there’s any real chance of a wave worth driving for. It’s promising but it’s over a week away, so keep an eye on it.
Outside of that, the rest of the time is flat or close to it — tiny 0.3ft to 1.0ft leftovers with barely any energy. Good for a swim, not for surfing.
So, bottom line: if you’re keen, mark your calendar for Sunday the 26th. The rest of the run is a write-off. — Rusty
