Alright, Rusty here. Let’s break down Whistling Sands (Porth Oer). It’s a quiet stretch, no two ways about it. The next two weeks don’t give us much to sink a rail into.
First real chance at a wave is Tuesday 7th July. Swell’s tiny – about 1ft from the SW with a short period. The morning is glassy, which is nice, but the energy is weak and the report calls poor surf. This break is inconsistent, so you’re used to waiting.
Then from Wednesday 8th July all the way to Monday 20th July, it’s a long dry spell. Flat days, bits of 0.3ft slop, and mostly cross-onshore winds making a mess of things. There’s a clean, offshore moment on Sunday 12th July morning but no swell at all. That’s a gap of over a week and a half.
The only real standout comes right at the tail end – around Monday 20th July afternoon through Tuesday 21st July morning. Swell bumps to 3ft to 3ft from the NNW, period still short at 4-5 seconds. Energy hits moderate levels. But the wind is onshore or cross-onshore, so it’ll be choppy and lumpy. For this sheltered beginner spot, that’s the best you’ve got. Not great, but it’s something.
Water temp is about 60°F – normal for this time of year.
If you’re kiting, those afternoons with fresh side-shore wind and a bit of chop will be more fun than paddling.
That late-July action is promising but short-period and wind-affected. Keep an eye on it, but don’t call in sick.
Rusty.
