The Lowdown
Alright folks, Rusty here. Let’s talk about the next 16 days for Falmouth – Swanpool.
First off, the water temp is about normal for this time of year, nothing to write home about.
Now, the honest truth: this is a tough outlook. We’ve got a long, dry spell coming up. From now until the 22nd of August, there’s basically nothing worth paddling out for. The swell is tiny, mostly under 1ft, and the energy is in the dirt – most of those readings are in the single digits or low teens. The combined energy barely flickers. You’ll see a brief pulse on Thursday the 13th with a 4ft swell from the WSW and a period of 11 seconds, giving us some moderate energy (299), and the wind is offshore from the NNW. That’s your best bet in the first week, but it’s still a small wave, more of a longboard glide than a proper session. The crowd factor is often there, so you won’t be alone.
After that, it’s a grim run of flat, clean but empty days right through until the 22nd.
The real standout, and the only one I’d circle on the calendar, is Saturday the 22nd of August. The afternoon shows a sudden jump: 6ft of swell from the WSW, but the period is a short 6 seconds. That’s a windswell, not a groundswell, so it’ll be a bit bumpy and disorganised. The wind is offshore from the WNW, blowing clean, and the combined energy hits 311 – moderate to strong. This is the only time the wave size gets over 5ft, so it’s pushing into intermediate territory; beginners might find it a bit much. The short period means it’ll be a bit fat and won’t hold a great shape, but it’s rideable, and with offshore winds, it’ll be the cleanest thing we’ve seen in weeks.
The rest of the second week is more of the same – small, weak, and mostly flat. The 24th has a morning pulse of 4ft from the WSW with offshore wind, but the energy is decent (254), just a smaller version of the Saturday.
So, to sum it up: the 13th is a tiny, clean option for a longboard, but the 22nd of August afternoon is the best offer of the whole 16 days. It’s not a classic, but it’s all we’ve got.
Rusty.
