Alright folks, Rusty here. Let's have a look at what's on offer for this stretch of coast. Honestly, it's a slow start and a tough run. We're looking at a long dry spell before anything even gets close to rideable.
The only spot in the picture is Devonport Rivermouth. It's a point-and-river setup that’s inconsistent and open to swells from the NW. Right now, water temps are sitting at 13°, which is about average for this time of year.
For the first few days, from Tuesday the 7th right through to Thursday the 10th, we’ve got nothing but tiny dribble – we're talking 0.3 ft to 1.0 ft, with the combined energy barely cracking 10 to 40 (weak). The winds are light and often glassy, but with zero swell to work with, there’s nothing to surf. It’s a total write-off.
We hit a bit of a change on Saturday the 11th, but it's not good news. The swell bumps up to 6 ft on Saturday morning and 10 ft by the afternoon, with the energy jumping to 239 and then a massive 1110 (strong to very strong). But here’s the catch – the period is a short and junky 6 to 8 seconds, and the wind is howling onshore from the NNW at 19 to 25 mph. It’s going to be blown-out, lumpy, and messy. Not for paddling. On Sunday the 12th, it’s still big at 8 ft to 8 ft, with a 7-8 second period and fresh cross-shore winds. Monday the 13th sees it drop a bit to 6 ft to 7 ft, but the wind is still fresh and messy. The whole stretch from Saturday through Monday is a poor-to-marginal call. That kind of wind and short-period swell on a beach setup is honestly looking more interesting for kite surfing than paddle surfing.
After that, it drops back to tiny waves again from Tuesday the 14th onwards, with heights mostly under 2 ft and very weak energy (under 160). The wind does turn clean and off or glassy at times, but with no swell, it’s just flat glass. This pattern of tiny, near-flat conditions looks to hold right through to Wednesday the 22nd, with only a couple of marginal bumps on the 18th and 20th that still have poor wind and short periods.
To be honest, there isn't a single standout session in this whole 16-day window. The only time the swell is big enough is ruined by howling wind. If you’re desperate, Sunday the 12th afternoon has 8 ft swell with a cross-off wind (19-22 mph from the W), but it’s marginal at best and the period is short at 8 seconds. It’s not going to be pretty. For a spot that’s already inconsistent, this is a rough run. Forecasts can change, but right now, I’d keep the board in the car and wait for a better window.
Rusty.

Information about the Devonport Rivermouth Surf forecast
The above surf forecast table for Devonport Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Devonport Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Devonport Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Devonport Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
