The Lowdown
Alright, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty grim for Trestrignel. I’ve scanned the whole 16-day window, and honestly, there’s not a single session I’d get excited about paddling out for. The whole stretch is a write-off for decent waves.
We’re staring at a long, quiet run. From now through to the end of the month, every single morning and afternoon report comes back as “poor surf conditions.” The swell energy is weak, barely cracking triple digits most days, and even when it does push a little higher – like around August 20th and 21st with combined energy in the 400s to low 500s (563 being the highest) – the wind is all over it. Cross-onshore and lumpy, onshore, just messy wind. The swell is short-period, mostly 7 to 9 seconds, so it’s weak and lacks any real push.
The water’s sitting at 66°F, which is a touch warmer than what’s normal for this time of year, but that’s the only highlight. The best we get is a little clean cross-off wind on the 23rd and again on the 30th, but the swell is tiny – 1 foot on the 23rd and 4 feet on the 30th – and the direction is all wrong. Trestrignel is sheltered and likes swell from the NW, but most of what’s forecast is WNW or even NNE, so it’s just not lining up.
There’s a pulse of bigger swell on the 24th August Monday morning, with 10 feet and combined energy hitting 987, but that’s coming with heavy rain and a fresh cross-onshore wind. That’s more of a blown-out, dangerous mess than anything surfable. For a beginner spot like this, that’s a firm stay-on-the-beach day.
So, bottom line: no standout sessions, no hidden gems. The forecast is flat and ugly. The kind of run where you don’t even bother checking the cams. It won’t stay like this forever – forecasts can change – but right now, there’s nothing worth chasing.
Rusty.

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.
