G'day, it's Rusty. Look, I've gotta be straight with you—this stretch at Rockpiles is a tough one. The whole 16-day window is a real struggle. There's no standout session, no day where everything clicks. The wind is a constant problem, blowing cross-off from the ENE, and it's strong right from the get-go. That ENE wind is also the direction for most of the swell, so the waves are just messy and won't have any shape. The energy is there, but it's all wrong.
Saturday the 11th kicks off with a messy 7.2ft of short-period ENE windswell, energy of 737 (moderate), but the wind is a fresh 22 mph cross-off, making it hopeless. The afternoon looks even worse, with a tiny 2.3ft swell that's long-period from the SW (18 seconds), but the wind is still howling. Sunday the 12th is more of the same: 6.9ft of bumpy windswell, 25 mph winds. It's all just poor.
The whole first week is a write-off. The wind barely lets up. On Monday the 13th and Tuesday the 14th, the swell drops, but the wind is still a fresh breeze, so the surf is marginal at best. The water temp is about average for the time of year, nothing to write home about.
We go through a long, bleak stretch. From the 16th right through to the 24th, it's a mix of tiny, long-period SW and SSW swells and weak, choppy ENE windswell, all with that relentless cross-off wind. The energy numbers are mostly in the 200-500 range (weak to moderate), but the wind kills it. Even the biggest days, like the 7.2ft on the 11th, are just blown out. This is a beach-and-reef setup, but with this much wind and crap quality, it honestly looks more interesting for a kite surfer than a paddler.
Finally, near the very end of the period, on Saturday the 26th, we get a slight change. The wind drops to a gentle 9 mph cross-shore from the E. The swell is still 5.6ft from the ENE, period 7 seconds, energy 620 (moderate). It's a cross-shore wind, so the surface will be a little bumpy, and it's still short-period stuff. It's the best the whole run has to offer, but that's not saying much. It's a marginal call, a last chance to get wet, but don't expect a classic.
