The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Whitesand Bay.
To be straight with you, it’s a rough stretch ahead. The whole 16-day window is a real mixed bag, and honestly, most of it is a write-off. There’s a long gap of flat, tiny, or just plain messy conditions. The only flicker of something rideable pops up on Thursday the 10th, and that’s about it.
The water’s sitting at 62°F, which is pretty much bang on for this time of year, so no surprises there.
Looking at the first few days, it’s a no-go. Thursday the 3rd and Friday the 4th have onshore winds howling at 15-22 mph, pushing up a lumpy 5ft to 7ft swell. The energy is there – you’ll see numbers like 304 and 548 (moderate wave energy) – but the wind is just trashing it. Saturday the 5th drops right off, with weak 3ft surf and a cross-onshore breeze. Not worth the wetsuit.
The only day that catches my eye is Thursday, September 10th. The afternoon session looks like the standout. The swell is a solid 6ft from the WSW with a period around 8 seconds, and the wind swings offshore from the east at a gentle 9 mph. That’s a clean setup for Whitesand Bay. The energy reading is 314 (moderate), and the conditions are described as “gentle offshore and clean.” This is your window. It’s a beginner-friendly spot anyway, and with that 6ft swell, it’s doable for most but could be a bit much for total newbies. Get on it if you can.
After that, it all goes pear-shaped. From Friday the 11th right through to the end of the forecast on the 18th, it’s a desert. The swell drops to under 3ft, and often as low as 0.3ft to 1.0ft. The wind is either howling cross-on, or the swell has no energy (most readings are under 100 – weak energy). A few days have clean winds but with absolutely no wave to push around.
So, bottom line: one solid afternoon on the 10th, then a whole lot of nothing. For a fairly consistent spot like Whitesand Bay, a run this blank is a bit of a bummer, but forecasts change. Keep an eye on it.
Rusty.
