The Lowdown

Alright, Rusty here, let’s talk about what’s on the menu at Barron Rivermouth.

First off, I’m not gonna lie to you – this 16-day window is a tough one. We’ve got a long, quiet stretch ahead. From Saturday the 1st of August right through until the morning of Tuesday the 5th, it’s basically a write-off. The swell is tiny, the wind is all over the place, and conditions are just plain poor. You’re looking at small, weak waves with a combined energy reading of only 192 (moderate) at best, and that’s with a cross-onshore breeze messing things up. Not worth paddling out for.

Now, there’s a little glimmer on Wednesday morning the 5th. The wind goes glassy, dead calm, which is a beautiful thing. The swell is only 1 ft from the SW, with a period of 15 seconds, so it’s a long-period groundswell. That long period means the sets will be a bit more spaced out, making paddling easier, but at this size, it’s really just ankle-snappers. The combined energy drops to just 82 (weak). It’s surfable, but it’s very ordinary. If you’re desperate for a splash, you could go for it, but don’t expect much.

Then we hit another dry spell. From Wednesday afternoon through the weekend, the conditions are back to being poor or marginal. The wind stays cross-onshore or onshore, and the swell stays small, never getting above 3 ft. The energy starts to build a bit, hitting 487 (moderate) on the afternoon of Friday the 7th, but that’s combined with a 9 mph cross-onshore breeze that messes up the surface. It’s frustrating because the swell is there, but the wind is just not cooperating.

The real standout, the one you’ve been waiting for, is on Sunday the 16th of August. The morning looks clean with glassy conditions, a 3 ft swell from the SW, and a period of 15 seconds. The combined energy is 281 (moderate), and the forecast is for good surf conditions. This is a classic, long-period groundswell that will wrap into the Rivermouth nicely. With the wind dead calm, it’s going to be clean and lined up. The water temperature is about average for this time of year, so no wetsuit surprises. Keep in mind, this is a point/river break, so it can handle a long-period swell without breaking too straight. It’s also fairly consistent, but crowds can show up sometimes, so get there early.

The rest of the week after the 16th looks like it might be a bit of a letdown again, with the wind picking up and the swell staying small. So if you can, make that Sunday the 16th your target date.

Rusty.

Information about the Barron Rivermouth Surf forecast

The above surf forecast table for Barron Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Barron Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Barron 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 (Barron 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 Barron 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.
