The Lowdown
Alright, Rusty here. Let's have a look at what's on offer for the region around Barron Rivermouth.
Right, straight up, it’s not looking like a classic run. We’ve got a long stretch of very small, weak surf ahead. The first recommendation for a surf is on Wednesday the 29th of July, but to be honest, it’s only just rideable. The water temp is sitting at 89°, which is a touch warmer than normal for this time of year.
Wednesday morning will see a 4ft swell from the southwest, with a long 16-second period. That’s proper groundswell energy, and the combined energy reading (1022) confirms it’s got some push. The problem is the wind is cross-onshore from the south at 6 mph, which will put a bit of a crinkle on the surface. Afternoon cleans up wind-wise, going onshore from the WSW at 9 mph, but the swell drops a notch to 4ft.
From Thursday through to the middle of next week, we are looking at tiny, weak waves. The swell drops below 3ft, and the period goes with it. The energy numbers slump into the hundreds, showing it’s really struggling. Winds are a mix of cross and cross-onshore, nothing that’s going to make these small waves any more appealing.
There’s a little flicker of hope very late in the run. Towards the 11th and 12th of August, the period starts to get long again, and energy climbs back up into the 400s and even 684 on the 11th afternoon. However, the wave heights are still small (3ft to 3ft) and the winds remain onshore or cross-onshore. For a river mouth/point break, those long-period swells can wrap in nicely, but we need a bit more size and better wind to make it a true standout.
The only real window that has a glimmer of being the best on offer is Wednesday morning, July 29th. It’s not perfect, but it’s the biggest and most energetic swell of the entire 16-day stretch, with 4ft of long-period SW groundswell. If you’re desperate for a paddle, that’s your moment. Just be ready for a few bumps from the wind. It is a point/river setup, so those long-period swells should line up reasonably well.
So, in short, a poor couple of weeks ahead. A small, semi-rideable window right at the beginning, and then a long stretch of flatness with only a whisper of something better feeling far away. The long-range stuff around the second week of August holds some promise but is less certain.
