The Lowdown
Alright, Rusty here again. Let's break down what's happening at Barron Rivermouth in the old scale.
We’re starting off with a slow period. The first few days are a total bust with tiny swell and crummy cross or onshore wind. You're looking at about a four-day stretch where there's no point even looking at the water.
The first chance to get wet is Wednesday morning, August 5th. The swell is only 1 ft from the southwest, so nothing to write home about. The wave energy is weak at 108. But the wind is glassy, dead flat calm. If you're keen for a longboard and a bit of a meditation session, it's technically rideable. The water temp is 89°, which is a touch warmer than average for this time of year.
The real standout is a week later. Friday morning, August 14th. That's the one. We’ve got a 3 ft SW groundswell with a long 18-second period. The combined energy jumps up to 538, a solid moderate pulse. And the wind? Glassy again. Zero wind. That’s going to mean clean, lined-up waves with some real shape at this point and river mouth. The long period will give them punch. This is the clear winner of the whole 16-day window, even if the size isn't huge.
Other than that, you'll see a few mornings with light breezes, but the conditions are either marginal or the wind picks up and ruins it by the afternoon. Saturday the 15th and Sunday the 16th have a little swell, but the wind stays messy.
So, aim for Friday, August 14th. That's your best shot for some clean, glassy waves at Barron Rivermouth.
Rusty.

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.
