The Lowdown
Alright, Rusty here again, giving it to you straight in feet and miles per hour.
This Trestrignel outlook is a long, hard wait for a very short window of clean waves. Most of the next two weeks is a write-off thanks to persistent onshore or cross-onshore wind chopping up the swell. But there is one morning that stands out.
Your best bet is the morning of Sunday, September 20th. That’s the clear winner. We’ve got a clean 5ft swell pushing in from the WNW with a 10-second interval. The combined swell energy is moderate (490), and the real kicker is a light cross-offshore breeze from the SSW. That will keep the surface glassy and the lines clean. This is your session. But don’t sleep in – Trestrignel is a sheltered spot, and with conditions this good, expect the crowd to be thick. Get there early.
After Sunday morning, the wind goes bad again. Monday the 21st has some leftover swell, around 4ft from the WNW with a long 13-second period – proper groundswell energy – but the cross-onshore wind will mess it up. It’s a marginal call at best.
Then things go quiet. From Tuesday the 22nd right through to the end of the period, the swell drops away. We’re looking at waves mostly between 2ft and 3ft, with very low energy. There are a few clean-looking mornings on the 24th, 25th, and 26th of September with offshore winds, but the swell is tiny, barely 2ft, with combined energy as low as 93. There’s no power behind it. Later, on the 28th, a little pulse of 3ft shows up, but the wind is straight onshore, so forget it.
So the story is simple: one solid shot on the 20th, then a whole lot of nothing. It’s a classic quiet spell for this area. Make that Sunday morning count.
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.
