The Lowdown
Alright, folks, Rusty here. Let's be straight up about what's happening in our little corner of the coast. We've only got one spot to look at: Whistling Sands (Porth Oer). It's a sheltered, inconsistent beginner's wave, so we're not expecting much action. The good news is, when there's nothing to recommend, the forecasts can always turn around.
Right now, the water is sitting at a touch warmer than average at 62°, so that's a small win. But for the next few days, from Sunday the 13th right through to Saturday the 26th of September, it's a real dry spell. There's no surf on offer that's worth a paddle. The waves are small, the wind is mostly cross or onshore, and the energy is weak – we're talking numbers in the 30s and 40s (combined energy of all swells directed here), just not enough to get excited about. We even get a near gale on the 18th kicking up 8ft of messy cross-shore chop, but that's more for the kite crew than paddle surfing.
We do see a glimmer around Tuesday the 22nd, with a 6ft swell from the NNW, but it's got onshore wind and the conditions are poor. Then we finally get some clean-looking windows from the 25th onward, but the swell is tiny – like 0.7ft to 2ft. The wind might be offshore or cross-off, but there's just no wave to ride. For a spot that rarely breaks anyway, this is a classic quiet spell. Hang tight, things can change.
Rusty.
