Alright folks, Rusty here. It’s been a quiet stretch, but I've been staring at the charts for Devonport Rivermouth and there's a glimmer of hope if you're patient.
The next week and a half is pretty flat. We're looking at tiny windswell, mostly from the NW, barely pushing 1 ft. The good news for that period? You'll see plenty of glassy, clean conditions, especially in the afternoons, and the water temp is about average for this time of year. It's just that there's no energy behind it – the combined swell energy is hovering around a measly 10–50 (weak). These will be days for a longboard paddle if you're desperate, but not for a real surf.
The real standout comes on Sunday, July 12th. We get a pulse of NW groundswell hitting 8 ft by the afternoon, with a short period of 8 seconds from the NNW. The wind swings offshore from the WSW, so it’ll be clean. Now, this is a point/river break, so that short-period swell might not wrap in with perfect shape, but it's the biggest energy we see, with a combined energy reading of 610 (strong). At 8 ft, this is expert territory. It's the only show in town and the crowds will be around, so get in early.
After that pulse, it fades fast. By Monday the 13th, it drops back to 2 ft with very ordinary conditions, and we slip back into flatness until around Saturday, July 18th. Another NNW swell arrives, pushing 6 ft, but it's onshore and choppy with a nasty 15 mph cross-on breeze from the NNW. The period is a short 7 seconds, so the waves will be lumpy and messy. The swell energy is moderate at 269, but it's not for a clean surf. A setup like that at a beach/river mouth looks more interesting for kite surfing than paddle surfing.
So, for two weeks of waiting, there's only that one decent day on the 12th. Make the call, but keep your expectations in check.
Rusty.
