The Lowdown

Alright, let's get into it.

Okay folks, let's talk about what we've got on the table for the next couple of weeks. The standout break is Barron Rivermouth. Don't get too excited just yet, because it’s a slow start. The water is sitting at a very warm 90°, which is a solid 4° above average, so that’s pretty unusual for this time of year. You're not going to need a full wetsuit, that's for sure.

We kick off with things looking a bit flat and messy. This Sunday afternoon, the 13th of September, is a write-off. The swell is a tiny 2 ft from the southwest with a long 13-second period, but the wind is cross-on at 9 mph, and the wave energy is pretty weak (273). It’s going to be choppy and poor.

Monday the 14th offers us the first real glimmer of hope. In the afternoon, the wind drops to glassy, and the swell holds at 2 ft from the southwest with an even longer 18-second period. The energy jumps into a moderate range (382). It’s the first time you’ll see something clean, but it’s still only knee-high.

Tuesday and Wednesday mornings bring more promise. Wednesday the 16th morning is looking sharp with glassy conditions and a 3 ft southwest swell, 16-second period, and solid wave energy (570). That’s your first real standout. Clean, long-period groundswell. Keep in mind, that long period means it might wall up a bit fast here, but for a point/river mouth, it should be a treat.

Thursday the 17th morning is another beauty: glassy again, 3 ft southwest swell, 14-second period, and good energy (525). That’s a top pick for a cleaner session.

After a bit of a lull in quality through the back half of the week and the weekend, we get another wave of clean conditions. Monday the 21st morning is glassy with a 3 ft southwest swell, 17-second period, and strong energy (552). That's a classic long-period glassy morning. Another standout.

Then we hit a bit of a quiet stretch until the very end of the run. The last week of September shows building swell, but the winds are often messy. However, Saturday the 27th morning brings a solid 4 ft SSW swell with a 13-second period and very strong energy (778). It’s onshore wind, but the size is there.

The real beast arrives on Monday the 28th of September morning. We see a 5 ft southwest swell, a 13-second period, and massive energy (1581). This is big. It’s only for experienced surfers at that size. The wind is light and onshore, so it could be lumpy, but the power is undeniable.

To sum it up: your absolute best windows for a clean, fun wave on a longer board are Wednesday the 16th morning, Thursday the 17th morning, and Monday the 21st morning. If you’ve got the skills and want some real grunt, keep an eye on that Monday the 28th, but it’s going to be a handful.

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.
