Alright, mate, Rusty here. Let’s be straight with you – this 16-day window is a real tough one. We’ve got a major gap of surfable waves to start. The first six days, from Saturday the 11th through to Thursday the 17th, are all showing "poor surf conditions" with tiny, weak swell. You’re looking at waves mostly under 2ft, and the wind is a constant problem – cross, cross-on, onshore... it’s all messy. The combined wave energy is low, sitting between 69 and 151 (moderate) at best, but the quality is just not there. It’s a real flat spell for the river mouth.
The best we’ve got in this whole period is a tiny window that’s still pretty average. On Monday morning, July 21st, the wind switches to a glassy offshore from the E at only 3 mph. That’s the cleanest we’ll see. The swell is a pathetic 1ft from the WNW with a period of 10 seconds, but with that light wind, it’ll be clean. The combined energy is a weak 47, so it’s tiny. This is a beginner-friendly wave, but it’s inconsistent, so you’ll be waiting for the odd rideable set. The water is about average for this time of year.
The only other half-decent look is Friday morning, July 24th, when we get a spike of 4ft from the NW but with a short period of 6 seconds. That’s a short-period windswell. The wind is a fresh cross-shore from the N at 19 mph, which will make it lumpy. The combined energy is 112 (moderate), but the quality is poor. It’s a choppy, lumpy mess, and honestly, with that wind and the beach-and-river setup, you’d be better off getting a kite out than a surfboard.
There’s a big gap from the 18th to the 20th with nothing but near-flat conditions and strong winds. The second week is a write-off, with tiny waves and strong cross-shore breezes. For a break that's fairly consistent, this is a frustrating run. We’ll just have to wait for the next forecast to change.
Rusty.
