The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this run looks grim for Whistling Sands (Porth Oer). The entire 16-day window is a write-off. There isn’t a single session that breaks through to offer anything decent.
The truth is, this is a sheltered, inconsistent beginner spot that rarely gets good, and this forecast proves it. For the next two weeks, we’re staring at a flat, messy pattern. The water temp is sitting around 60°, which is basically average for this time of year – not that it’ll help with the lack of waves.
We start off Sunday the 2nd with nothing but a tiny 0.3ft ripple from the SW, with an energy reading of just 4. The wind is offshore on Sunday morning, so it’s clean, but clean on a puddle doesn't make a surf. Monday the 3rd and Tuesday the 4th aren’t any better, with heights staying below 2ft. There’s a slight uptick on Wednesday the 5th, with 5ft of short-period, cross-onshore junk – energy hits 261 in the afternoon, but it’s lumpy and chopped to bits by a fresh breeze. Poor conditions all around.
Then we hit a long, dead gap. From the 6th right through to the 16th of August, the swell is tiny or non-existent. There’s a 0.3ft glassy moment on Wednesday the 12th with a long 12-second period, but it’s essentially flat. The energy levels stay in the single or low double digits, with a few days hitting zero. The only real movement comes right at the end, on Sunday the 16th, with 6ft of short-period swell from the WSW, but it's cross-onshore and choppy again. The combined energy is moderate at best (261), but the quality is poor, and the wind makes it a messy, lumpy option. On Monday the 17th, it drops back to nothing.
In short, don’t bother paddling out for the next 16 days. This is one of those blank runs that’s unfortunately normal for a spot like this. I’d keep an eye on the charts, but for now, the gear is staying in the van.
