The Lowdown
Alright folks, Rusty here. Let’s see what’s cookin’ for the next couple of weeks.
Right off the bat, I gotta be straight with you: it’s a long, flat wait. There’s absolutely nothing worth paddling out for from the start of the period right through until early on Monday, August 10th. That’s over a week of tiny, weak, or choppy slop. The wind is messy, the swell is barely a ripple, and the combined energy sits at a pathetic 12 (weak). You’re better off waxing your board and staring at the ceiling.
But then, Monday, August 10th throws us a curveball. A solid pulse of northerly swell rolls in for the morning. At Devonport Rivermouth, we’re looking at a clean 10-foot swell from the north, with a short period of 7 seconds. That’s a lot of water moving, and the combined energy is a hefty 945 (strong). The wind is light and offshore from the SSW, which cleans it right up. This is the standout window, but listen – at 10 feet, this is for experienced surfers only. The short period means it’ll be a bit dumpy and fast, but the offshore wind will make for some proper, heavy wedges. The water temp is about 55°, which is smack bang average for this time of year.
The afternoon of Monday the 10th gets a bit dicey with a cross-on breeze, but the energy actually jumps up to 1114 (very strong). It’s marginal, but for the big-wave crew, that’s a raw, powerful ocean.
Tuesday morning, August 11th is your next best bet. The swell drops back to a much more manageable 5 feet from the northwest, with a period of 7 seconds. The combined energy is still a solid 303 (moderate). The real kicker? It’s glassy. Zero wind. That’s pure gold. The wave quality will be good, and it’s clean as a whistle. A much more user-friendly size than the day before, though still solid. This is the pick for the average punter who wants a real session.
Beyond that, it fades out again. The rest of the second week is a write-off, with tiny, clean but completely powerless swell. The combined energy drops to three-digit lows and then into two-digit rubbish. You’ll be floating out there, not surfing.
So, to wrap it up: wait for Monday, August 10th if you’re a charger, or Tuesday morning, August 11th for a cleaner, more manageable wave. The rest of the time? Keep the board in the bag.
Rusty.
