Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

Honestly, it’s a pretty grim stretch ahead. For the first week and a half, we’re looking at a whole lot of flatness with barely a ripple. The first few days, from Monday the 6th right through to Friday the 10th, the swell is tiny, mostly 0.3 ft to 1.0 ft. It’s clean in the afternoons, often glassy, with some cross-off winds in the mornings, but there’s just no wave energy to work with. The combined energy is under 50 (9 to 49) for most of that time, so it’s dead flat. You’re not surfing that.

Come Saturday the 11th, the wind starts to howl from the north, getting up to 19 mph by the afternoon, and the swell bumps up to 3 ft on a short 5-second period. It’s choppy, lumpy, and just a mess. Not worth a paddle.

Then we get a bit of a pulse on Sunday the 12th, but it’s not pretty. The morning brings 7 ft of swell from the NNW with a short 8-second period, but the wind is a strong 25 mph cross-shore, making it a total washing machine. The combined energy is a solid 620, so there’s plenty of power, but it’s not for surfing. By the afternoon, the swell jumps to 10 ft, energy hits 1241, but the wind is still fresh and cross-off, so it’s clean. Still, 10 ft is big, expert-only territory, and the short period means it’s going to be a wall of white water. This setup looks way more interesting for kite surfing than paddle surfing.

The rest of the run is a bust. Swell drops back to under 3 ft for most of the next week, with poor winds and poor surf conditions every day. The only break on offer is Devonport Rivermouth. It’s a point/river setup, which is a bonus for holding a bit of shape, but it’s inconsistent and rarely breaks. Water temps are sitting at 56°F, which is about normal for the time of year. That’s cold, but you’d be used to it.

The best you can hope for is a couple of marginal sessions. Wednesday the 15th afternoon brings 6 ft from the WNW with a 7-second period, and clean cross-off wind from the SW at 16 mph. The energy is 296, so there’s some push. It’s nothing special, but it’s the most surfable you’ll see. Then Thursday the 16th morning and afternoon both have 1 ft of 16-second period groundswell from the NW, with glassy conditions. The energy is 103 in the morning, dropping to 93, so it’s weak. That long period will make it break straight and lined up, but at 1 ft, it’s just a tiny, clean ankle-snapper at the river mouth.

Beyond that, it’s flat again. A long blank run like this is pretty normal for the area, so don’t hold your breath. Forecasts can change, but right now, it’s a waiting game.

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.
