Devonport Rivermouth Surf Forecast and Surf Report

Alright, Rusty here again. Let’s break down what we’ve got coming for Devonport Rivermouth over the next 16 days.

Honestly, I’m looking at a pretty grim stretch. From Tuesday 14 July all the way through about Wednesday 22 July, it’s basically one long gap of nothing worth paddling out for. Swell heights are tiny – mostly 1.0 ft to 4 ft – but the real problem is the period. For most of that first week, we’re talking 5 to 7 seconds of windswell, which means no grunt, no shape. The combined energy is in the weak range, with numbers like 203 that one Tuesday afternoon, but that’s an outlier for an otherwise skinny window. Winds are cross or cross-off from the west/northwest, so the surface stays clean, but there’s just no push behind the waves.

Come Thursday 23 July, we finally get a long-period groundswell (15 seconds) with energy numbers hitting 136 and 139, but the wave height is still only 1 ft. That’s a tease – the Rivermouth point loves that long-period NW swell direction, but at that size, it’s barely a ripple. The wave comment says “surfable but very ordinary,” and that sums it up.

Another gap from Friday 24 July morning through the end of the forecast. The one half-decent window is Saturday 25 July afternoon: 4 ft of northwest swell, combined energy of 200 (moderate), and glassy conditions from a light NNE breeze. That’s the cleanest we’ll get, but the period drops back to 6 seconds, so expect weak, lumpy waves. The morning of Saturday 25 also gets a “surfable but very ordinary” note, so it’s not like we’re spoiled for choice.

Devonport Rivermouth is a point/river break that’s already inconsistent. It needs a solid NW swell to really fire, and we just don’t have the size in this window. For a beginner-friendly spot, these waves are mostly too small or weak to bother with. Water temp’s about 55°F, pretty average for July.

So, here’s the blunt truth: there are no good surf options in this whole 16-day window. The only thing close to a standout is Saturday 25 July afternoon, with clean, glassy conditions and 4 ft waves. But even that’s a weak, short-period swell that’ll be soft and gutless. Periods like this happen here – especially with an inconsistent break like this one – and you just have to wait for the next proper swell. Keep an eye on the charts.

Rusty.
