The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Whitesand Bay. Gotta be straight with you – this is a tough stretch. We’re lookin’ at a 16-day window with a big, long gap of real poor conditions before anything worth paddling out for shows up.
For the first 15 days, from September 13th right through to the morning of September 28th, it’s a write-off. The swell’s there at times, like on Saturday the 19th we see a bump to 7ft from the WSW with combined energy of 499 (moderate), but the wind is a strong onshore breeze at 25 mph. That combo makes for messy, blown-out junk. A lot of these days have cross-onshore winds and the wave comment is “poor surf conditions” – not worth your time. Even Tuesday the 15th morning has 5ft from the W with onshore winds, but it’s all lumpy and ugly. There’s a real stretch of nothing.
Now, here’s the one glimmer. On Monday the 28th of September, in the morning, we finally get something. The wind swings around to light offshore from the ENE at just 6 mph – that’s clean conditions, a major positive. Swell is small, only 3ft from the WSW, with a period of 8 seconds and combined energy of 101 (weak). It’s not gonna win any awards for size, but the wave comment says “surfable waves but very ordinary conditions.” For this bay, after such a blank run, that’s the standout. The break is Whitesand Bay, a beginner-friendly, fairly exposed spot. Optimum swell direction is WSW, and that’s exactly what’s coming. With the offshore wind, it’ll be glassy and clean. Don’t expect barrels, but for a longboard or a funboard, that Monday morning is the only game in town. Crowds are possible here sometimes, so with the conditions this clean, expect a few others with the same idea.
Water temp is about average for the time of year.
So there you have it. A long dry spell, but a tiny window of clean, surfable waves right at the end. Get on it if you can.
Rusty.
