The Lowdown
Alright folks, Rusty here. Let’s get into it for this neck of the woods. We’ve got a long stretch ahead, but it’s not exactly firing on all cylinders. The overall pattern is small, with a lot of wind making things messy. The standout window is narrow, but there’s a few moments when it could be worth a paddle.
The first real surf we can talk about is on Wednesday the 9th, early. Barron Rivermouth is a point/river setup, and it’s exposed to the SW swell. The water is sitting at 89°, which is 4° warmer than average for this time of year – that’s notably warm, so you’ll be surfing in a bath.
Wednesday morning looks like the pick of the whole run. The swell is a clean 2 ft out of the SW, with a very long period of 19 seconds. That’s groundswell, and it’s got a nice energy level (394). The wind is glassy – dead calm – which means the surface will be like a mirror. That’s a major positive. It’s a small window, but it’s the best you’ll get. The wave energy is moderate, but for a wave that small, the long period will give it some shape.
Tuesday afternoon the 8th is a write-off, with cross-onshore wind and poor conditions. Expect a gap of a few days with no real recommendations after the Wednesday morning window. The surf tries to pick up again towards the end of the second week, but it’s still small and gets chopped up by the afternoon wind.
Looking way out, there’s a glimmer on Monday the 21st morning. The swell is a bit bigger at 3 ft from the SW, with a period of 17 seconds, and the energy is solid (556). The wind is light and offshore from the WSW, so it will be clean. This is promising but it’s a long way off, so don’t book the day off work just yet. The morning of Tuesday the 22nd also has glassy conditions with a 3 ft SW swell and 16-second period (483 energy), but again, it’s a long-range call.
For the most part, the afternoons are a mess with cross-onshore winds. The setup is a point/river, so it can handle a bit of swell, but those afternoon winds will ruin it. If you’re a beginner, the swell never goes over 5 ft, so it’s never too big, but the quality is often poor. The crowds are listed as “sometimes” at Barron Rivermouth, so on the good mornings, you might have a few others out, but it won’t be a circus.
If you’re a kite surfer, the afternoons with moderate cross-onshore wind and that consistent SW swell energy might look more interesting than a paddle session.
So, bottom line: the best bet is Wednesday morning the 9th for a glassy, small, long-period session. The Monday morning the 21st is a long-range hope. Otherwise, it’s a lot of waiting for the wind to play nice.
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.
