The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Barron Rivermouth. It’s a slow start, but there’s a couple of windows that’ll get the heart racing.

First thing, the water’s sitting about average for this time of year, so no surprises there. The whole 16-day period is a bit of a mixed bag of small, long-period SW groundswell. Don’t get too excited about the size; we’re mostly looking at knee-to-waist high stuff. The real story is the wind.

For the first week, we’re dealing with a lot of cross-onshore and onshore breezes. Thursday the 6th through to the 11th is pretty much a write-off for a decent surf. The swell is there, but it’s small and the wind messes it up. The combined energy is weak to moderate (183 to 416), which tells you it’s not packing much punch. It’s a lot of chop for not a lot of reward.

Now, things start to look up. Saturday the 8th afternoon, the wind goes offshore (NE at 6 mph) and cleans it up. The swell is 3 ft from the SW, period 16 seconds, and the energy is moderate (411). It’s not a monster, but it’ll be clean and fun. That’s a good little window.

But the real standout, the one you want to circle on the calendar, is the morning of Friday, the 14th of August. The wind is glassy (SE at 3 mph), and the swell bumps up to 3 ft from the SW with a very long 18-second period. The combined energy jumps to 761, which is a solid moderate energy. The wave comment says "expect very good surf conditions." This is the pick of the run. That long period will make for some nice, lined-up waves, perfect for a river mouth point break. Get in early, because crowds are possible here.

We also have the morning of Wednesday the 12th and the morning of Monday the 17th offering glassy conditions with 3 ft and 3 ft of SW swell respectively. The 12th has moderate energy (383), and the 17th is a bit weaker (269). Both are solid options for a clean session, but the 14th is the one with the most juice.

After the 14th, the swell holds a bit but the wind gets messy again. The 15th and 16th have onshore and strong cross-onshore winds that’ll chop it up. The last few days from the 18th to the 21st look small and mostly blown out. Early next week, the 21st of August, has a moderate cross-shore breeze making it messy.

So, to sum it up: don't bother with the first week. Aim for the 8th afternoon for a clean little wave, but the absolute winner is the early morning of Friday the 14th. Keep an eye on the forecast for that one.

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.
