The Lowdown
Alright, it’s your local surf reporter Rusty here. I’ve had a good look at the charts for Trestrignel, and I’ve got to be straight with you—this one is a tough pill to swallow. The whole 16-day window is looking pretty lean, with a big, sad gap of nothing really worth paddling out for.
Let’s start with what’s on offer. The first real chance to get wet that’s even worth mentioning doesn’t come until Tuesday, August 11th. The morning session is the standout here, and the only one I’d really call a highlight. We’re looking at a clean, glassy morning with a slight air and a 3ft swell from the west, with a period of 8 seconds. The combined energy is moderate, sitting at 162. It’s not big, it’s not world-class, but with the wind going glassy, the conditions will be clean and the surf in the chest-high range. It’s a beginner-friendly size, so it’s a good chance for a fun, uncrowded session. The water temperature at Trestrignel is about average for this time of year, so no surprises there.
The problem is, before that, we’re looking at a solid 10-day stretch of poor surf. The first few days of August are a write-off—tiny, weak, choppy, or blown out. The swell tries to get its act together on the 5th and 6th, with a bit more energy (up to 290 on the 5th afternoon), but the wind is cross-onshore and lumpy, so it’s a mess. Then on the 9th and 10th, we get a proper pulse of swell—7ft to 8ft, with strong energy readings (876 and 746). That’s sizey, over 8ft on the 10th morning, which is expert-only territory, but the wind is cross-on or onshore, and the wave comment says “poor surf conditions.” The period is also short, around 8-10 seconds, so it’s not the clean, long-period groundswell you want for a sheltered spot like this. That setup looks more interesting for kite surfing than paddle surfing.
After Tuesday the 11th, it fades back to tiny, weak, and mostly cross-shore or onshore again. The rest of the window is a bust. The swell is small, the period is short, and the wind isn’t cooperating.
So, the honest truth? This is a 16-day forecast with a big, 10-day gap of nothing good at the start, and only one brief, promising window on the 11th. It’s not a complete blank—there *is* a surfable day—but it’s a long wait for a small, clean wave. The only standout is the morning of August 11th at Trestrignel. If you’re patient, you might get a fun, glassy session. Otherwise, the forecasts can change, and it’s not a dead zone forever.
Stay stoked, but maybe bring a book.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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.
