The Lowdown
Alright, let’s get stuck into this forecast for Trestrignel. I've been staring at the charts and, honestly, it's a bit of a grim run ahead. For a spot that's sheltered from the north-west, we're not seeing the goods line up at all.
Right off the bat, the first few days are a write-off. Sunday the 9th through to Tuesday the 11th, we’re looking at tiny, weak swell around 1ft to 2ft from the WNW. The combined swell energy is pathetic, bottoming out at 35 (weak energy). Worse than the size is the wind – it’s cross-on or cross, and breezy, making for choppy, messy conditions. There’s just nothing to get excited about.
We get a little flicker of hope on Wednesday morning the 12th. For a brief window the wind goes light offshore from the SSE, cleaning things up nicely. The swell picks up to 2ft from the W, with a period of 10 seconds, and the energy bumps up to a moderate 136. It’s surfable, but very ordinary. Don't expect much. If you’re a beginner, that morning session might be your only shot, but the swell is tiny.
After that, it’s back to the doldrums. Thursday the 13th sees a bigger, longer-period 3ft swell from the W arrive, pushing the energy to 237 (moderate). But the wind swings back onshore and cross-onshore, wrecking it. Friday the 14th and Saturday the 15th are similar stories: building swell up to 4ft, but the wind is always wrong, keeping the surface junked up.
The whole second week looks poor. From Sunday the 16th all the way through to Monday the 24th, the pattern is relentless. Thumping cross-shore winds, mostly from the NE and NNW, keep things lumpy and choppy. The swell tries to hang around on the 22nd with a 4ft groundswell from the NW, but the period is a short 6 seconds, and the energy is weak to moderate. It's clean for a moment on the 22nd morning with a cross-off wind, but it’s so weak it’s barely a ripple.
Honestly, don't bother paddling out for most of this. The fetch is wrong, the wind is wrong, and Trestrignel is just taking a beating. With all that cross-shore wind and building swell, this setup actually looks more interesting for kite surfing than paddle surfing. The wind will be strong and the waves messy – perfect for a kite, not a surfboard.
Keep the stick in the car for the 12th morning, maybe. Otherwise, find something else to do because the ocean is not playing ball here.

Further information to help with frequently asked questions about our surf forecast for Trestrignel may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
