The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for Whitesand Bay.
Honestly, mate, this is a tough stretch. The next couple of weeks are lookin’ pretty flat and ordinary for Whitesand Bay. We’ve got a real dry spell on our hands. There’s a gap of about a week with no decent surf on offer right from the start.
Monday the 14th is a write-off – poor surf conditions with a fresh cross-onshore wind ruining any shape. The swell is there, around 4ft from the WSW, but with 16 mph wind, it’s just a choppy mess. The combined swell energy is weak to moderate (196) but the wind just kills it.
Tuesday the 15th through to Saturday the 19th is more of the same. Swell sticks around the 5ft to 6ft mark, coming from the W and NW, but we’re pinned with onshore and cross-onshore winds gusting 19-22 mph. The combined energy bumps up a bit – 255 on Tuesday morning – but it’s all blown out. Not worth paddlin’ out for a beginner, and for anyone else, it’s just frustrating.
The water temp is 62°, which is a touch warmer than normal for this time of year – a little pleasant if you’re just standin’ on the beach, I suppose.
Now, there’s a glimmer of hope towards the end of the run. Monday the 22nd of September, we finally see a bit of a change. The morning has clean conditions with a light cross-offshore breeze from the SSE at 6 mph. The swell is tiny, only 2ft from the WSW, and the combined energy is weak (41). It’s surfable but very ordinary. Still, it’s clean. That’s the closest we get to a standout, and it’s a pretty low bar.
Tuesday the 23rd morning is similar – clean, light wind, with a 1ft swell from the WSW. The period is a long 11 seconds, which suggests some better shaped waves, but there’s just not enough height to do much with it. The combined energy is weak (80). After that, it fades back into tiny, clean but weak conditions for the rest of the week, with swells barely breaking 3ft.
Honestly, the whole 16-day window is a bust. There’s no real stand-out session. If you’re desperate for a paddle, the cleanest windows are the mornings of the 22nd, 23rd, and 25th, but you’ll be on a log or a longboard, and you’ll be workin’ for every ride. For the most part, it’s a blank run, and that’s just how this spot goes sometimes.
Stay patient, the forecasts can always change.
Rusty.
