The Lowdown

Alright, Rusty here again. Let’s break down the same stretch in imperial, for those of you who think in feet and degrees Fahrenheit.

Same story: the first few days are marginal, but there are a couple of glassy windows that are worth the wait. The water temperature is about 89°F, which is much warmer than normal for the time of year—about 4°F above average, so you’ll be feeling it in a spring suit or less.

The swell is a consistent southwest groundswell, mostly between 2 and 3 ft, with periods running 14 to 19 seconds. That’s proper groundswell with energy readings in the moderate range (e.g. 394, 464, 499). The river mouth handles that long period well, so it should wrap in with shape.

The clear winner is Wednesday 16 September morning. You’re looking at 3 ft of SW swell with a 16-second period, and the wind is glassy out of the south-southwest at 3 mph. Combined energy is 505. That’s about as good as it gets in this stretch. Crowds can be a factor here sometimes, so be early.

Wednesday 9 September morning is a close second for the early birds—2 ft of SW swell at a very long 19 seconds, glassy winds at 3 mph, energy at 394. Tiny but perfect.

Thursday 17 September morning is another glassy session (3 mph from the NW) with 3 ft of SW swell at 14 seconds and energy at 459. Clean but a step down from the 16th.

Most afternoons are blown out by cross-onshore or onshore breezes, and by the second week the wind gets worse. Around 20 September, the swell bumps to 3 ft but it’s choppy. Those afternoons are more for kites than paddles.

Top pick: Wednesday 16 September morning. Second spot: Wednesday 9 September morning.

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.
