The Lowdown
Alright, Rusty here. Let's have a look at what's on offer for your neck of the woods.
Well, I gotta be straight with you, this sixteen-day outlook is a real bummer. There’s nothing here that gets me excited, and for the first week, it’s pretty much a write-off. There's not a single wave worth paddling for. You're looking at a long dry spell starting from now, right through the first week of September. The first chance for anything, and I use that word loosely, creeps in on Saturday the 5th, but even that’s a struggle.
The only spot I’ve got to work with is the Devonport Rivermouth (point/river) and the setup is tricky. It’s an inconsistent little river mouth, and it rarely handles much. The water temp is sitting around 55°, which is pretty average for this time of year, so nothing unusual there.
Let’s run through it. From Tuesday the 1st right through to Friday the 4th, you’re looking at everything from nothing to small, messy, cross-shore junk. Not worth a second look. Then on Saturday the 5th, we finally see some size. The morning is a bit intense with a 10ft swell from the NW and a 22 mph cross-off wind from the west. The combined swell energy is pumping at 1097, which is strong, but with that size and power, it’s going to be a washing machine and only for the hardcore experts. The afternoon cleans up a touch, dropping to a 8ft NW swell with a 16 mph cross-off, energy still high at 901. It’s a ‘marginal’ call, meaning the tide might mess it up. It’s the closest thing to a standout, but with crowds “sometimes” an issue here, it’s more of a mission than a treat. Too big for beginners.
After that, the plug gets pulled. Sunday the 6th and Monday the 7th are back to tiny, weak leftovers, and the rest of the window through to Wednesday the 16th is just a sad mix of very small waves – like 0.3ft to 1ft – and nothing that would ever get a surfer out of bed. The wind goes glassy a few times, but you can’t surf glass with no swell.
The extreme long-range, around Wednesday the 16th, you get a pulse of 4ft from the NW, but it’s got a terrible period of 4 seconds. That’s just wind slop, not a real wave. Nothing to plan for.
So, bottom line: don’t bother. This is a blank run for the area, which is a normal thing now and again. Forecasts can change, but right now, there’s nothing to chase.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Devonport Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
