The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are shaping up like for this stretch of coast.
Honestly, the outlook is a tough one. We’ve got a long, quiet spell ahead with very little to get excited about. The first real chance of anything rideable doesn't show up until Wednesday the 23rd of September, which is a solid ten-day gap with nothing worth paddling out for. The surf just isn't there, and the wind and conditions are mostly a mess.
The only time the ocean starts to show a bit of life is the morning of Wednesday the 23rd of September. Whitsand Bay and Tregantle might just offer a sneaky window. We’ll see a lump of 5ft swell pushing in from the SW, but the period is a short 6 seconds, so it’ll be a bit fat and unorganized. The real story here is the wind: glassy conditions, flat calm. That is the one major positive. For a beach that can get messy quick, a clean, smooth ocean is a big deal. The water is a touch warmer than normal for the time of year at 65°.
After that brief moment, the wind turns onshore again that afternoon, and the swell drops back down. Thursday the 24th has some cleaner cross-offshore winds and a bit more energy in the water, but the swell height is only 3ft from the WSW with a longer period of 12 seconds. It’s a possibility, but it’s very marginal. This break is inconsistent at the best of times, and crowds can be a problem, so don’t expect much company for these tiny, marginal waves.
Overall, it’s a waiting game. That Wednesday morning is your best bet, and it’s a fragile one.
