The Lowdown
Right then, let’s see what we’ve got for Whitesand Bay. To be straight with you, it’s a pretty bleak run. There are some swells trying to show up over the next couple of weeks, but the wind is going to absolutely ruin most of them. This isn’t a time to get excited, but there are one or two very brief windows where it might just be worth a paddle.
The first bit of hope comes on Sunday the 13th of September. We’ve got a small, clean pulse of swell rolling in. Friday the 11th afternoon shows a light onshore breeze with a 3ft swell from the WSW, period of 9 seconds, and the combined wave energy is moderate at best (164). It’s not going to be great, but it’s clean. However, the real standout is Sunday afternoon. The wind drops to glassy, dead calm. The swell is a tiny 3ft from the WSW, with a 9-second period and combined energy of only 131. It’s not going to be big or powerful, but if you’re a beginner or just want to get wet on a longboard, the glassy conditions will make it look better than it is. That is the best on offer. The water temp is 62°, which is about normal for this time of year.
Then, after that, we go into a big hole. Monday the 14th through to Saturday the 19th of September is a mess of strong cross-onshore winds and lumpy, choppy conditions. There’s a big spike in swell on the 19th with a 8ft WSW swell and combined energy of 690, but it’s blowing 12 mph onshore. That’s way too big for beginners, and the wind will make it a washing machine for experts. Not worth it.
The next real chance doesn’t come until Sunday the 20th of September morning. There’s a 7ft swell from the W, period of 7 seconds, and combined energy of 499. The wind is light and cross-shore, so it’ll be a bit lumpy but not as messy as the days before. The forecast says it’s marginal. It’s a big swell though – only for experienced surfers.
Looking further out, the last week of the forecast is all about clean conditions but tiny waves. From Monday the 21st to Wednesday the 23rd, the wind is finally offshore or cross-offshore, but the swell drops to 2ft or less. The combined energy is under 50. It’s clean, but there’s barely a ripple. Thursday the 24th has a tiny 1.0ft swell from the W with a very long period of 11 seconds, but the energy is pitiful (50). It’s a groundswell, but there’s not enough of it to do anything.
Overall, this is a tough outlook. The swell and wind just won’t line up. The only true standout is that glassy Sunday afternoon – small, clean, and for those who just need to get out there.
