Trestrignel Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a proper look at what’s on offer around Trestrignel.

Honestly, the next week and a half is looking pretty grim. We’ve got a long stretch of poor surf conditions that’s going to test your patience. The first decent wave energy shows up around Thursday the 2nd of July with a combined swell energy of 427 (moderate energy), but it’s a cross-onshore wind from the WNW at 12 mph and the water is a bit warmer than usual for this time of year at 63°F, with a 2°F anomaly – that’s a little notable but nothing too wild. Still, that first swell is ruined by the wind, and that trend just keeps going. Day after day we see cross-on or onshore winds and choppy, messy lineups. Even when the swell drops off, the wind stays in the way.

After that initial burst, the energy fades fast: from 419 down to 245, 205, 150, all the way down to double-digit figures. By the 7th of July, the combined energy is only 73 (weak), and it stays weak for days. The swell period hovers around 8 to 10 seconds, so it’s a mix of short-to-average period, nothing with real punch. Honestly, between the 2nd and the 10th of July, there’s nothing worth paddling out for. The wind is wrong, the surf is messy, and the scores are all zeros.

Now, here’s a flicker of hope. On Saturday the 11th of July, the morning shows a change. The wind goes glassy – dead calm, 0 mph from the NNE. The swell is small at 4ft from the NE with a short 5-second period, and the combined energy is only 134 (weak). It’s not going to be a world-class session, but it’s surfable, clean, and for a beginner-friendly spot like Trestrignel, that’s a rare win in this outlook. It’s the only time in the whole 16 days where the conditions line up for a clean wave. After that, it’s back to the usual story: cross-onshore wind, choppy surf, and tiny swell.

The following week is a write-off. From Sunday the 12th right through to Friday the 17th, the combined energy is mostly under 100 (weak), the waves are under 3ft, and the wind is either cross-on or straight on. The period drops to 4 or 5 seconds at times – basically wind chop. The swell direction swings all over the place, but none of it matters with the wind ruining it. There’s a brief moment on Thursday the 16th where a light 3 mph W wind comes in, but the swell is only 1ft, so it’s a flat day.

Best bet: If you’re desperate for a paddle, set your alarm for Saturday the 11th of July morning. Glassy conditions at Trestrignel, even with small, short-period waves, will give you the cleanest session of the entire period. For everyone else, this is a two-week block to clean your gear and wait for the next proper swell.

Stay patient,
Rusty.
