The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks. I’ll be straight with you – it’s a pretty lean stretch. We’re looking at a long, quiet start with almost nothing worth paddling out for until the end of the week.
The first real chance to even think about a wave comes in on Friday the 24th of July. Up until then, it’s flat to tiny. We’re talking about a solid 7-day gap with no surf worth mentioning. The water temp is sitting at 13° and it’s pretty much normal for this time of year, so the wetsuit is your friend.
The one spot that gets a little bit of life is Devonport Rivermouth. This is a point/river setup, and it’s known for being inconsistent, so you’ve got to pick your moments. The best of a quiet bunch looks like Saturday the 25th of July. On the Saturday morning we’re looking at a 5 ft swell from the NW, with glassy conditions. That’s clean, no wind, and the swell is a manageable size. The combined energy hits 175 (moderate), and the offshore wind for the spot is from the SSW, so the glassy morning is a real bonus. The afternoon is similar, a 5 ft NW swell, with a light cross-off breeze keeping it tidy. The period is short at 6 seconds, so it’s not a groundswell with huge power, but for a river mouth, it’ll be rideable. Crowds are possible here, and with it being a weekend, expect a few locals out.
Sunday the 26th of July drops off a bit, with the swell back down to 3 ft and a fresh 16 mph wind, which makes it less appealing. The winds pick up again later in the week, and by the 28th of July (Tuesday), we see a big jump in size – 10 ft but with a fresh 22 mph cross-shore wind. That’s a messy, lumpy setup, and the combined energy is a hefty 1030 (strong). That’s for experts only, and even then, the wind is a problem. It's more of a wind-swell or kite-surfing day than a clean paddle session.
The second week looks quieter again, with tiny 0.5 ft to 1 ft waves and clean conditions, but nothing to get excited about. The long-range outlook is promising but not certain; the forecasts can change, but for now, keep your eyes on that Saturday the 25th.
Rusty.
