The Lowdown
Alright, folks, Rusty here. Let me level with you – this 16-day window for Trestrignel is a tough one. The spot’s a classic beginner-friendly, fairly consistent little wave, always got a crowd, but the conditions are just not playing ball. We’ve got a run of poor surf from July 18th right through, and not a single day that I’d call rideable for a proper surf.
The pattern starts with tiny swell – 1ft to 1.3ft – and cross‑onshore or onshore winds from the northwest and north‑northwest. The combined wave energy is weak, mostly in the teens and twenties (21, 20, 17, etc.). Short period, messy chop. That’s a no‑go for anyone.
The 20th to the 22nd of July sees a bit of a period bump – up to 12 seconds on the 20th morning – but the swell is still only 0.7ft and the wind is cross‑shore. Still poor. The energy stays low (24–39). By the 23rd and 24th, the swell lifts a little – 2ft on the 23rd morning, period 5 seconds – but that’s a short, weak windswell, not worth paddling out for.
Now, there’s a pulse of bigger swell around the 27th and 28th of July. The swell height climbs to 5.9ft and 6.2ft, with combined energy jumping into the 400s (439, 463, 460). That’s moderate wave energy, but here’s the killer: the wind is cross‑onshore from the west‑northwest, and the period is only 8 seconds. That means short, lumpy, wind‑affected waves. For a beginner spot like Trestrignel, anything over 5ft is already pushing it, and with that onshore wind it’s just a mess. The 29th sees a drop to 3.9ft and 3ft, and the wind shifts to onshore from the north‑northwest with a light breeze, but the energy is still moderate (227, 119) – but again, poor surf conditions.
The rest of the run into early August keeps the swell small (2ft–4.3ft) and the wind cross‑onshore or onshore. August 1st morning has a period of 6 seconds and a light onshore breeze – not enough to make it work.
So, bottom line: there are no good surf options in this 16
