The Lowdown
Alright folks, this is Rusty. Let’s have a look at what’s coming up for Trestrignel.
Right off the bat, I’ve got to be straight with you: the next week or so is a bit of a struggle. We’re looking at a long gap with no real standouts to get excited about. The main problem is that the swell direction is coming from the west, but this spot is best with a northwest swell, so it’s fighting against the grain. For the first few days, the waves are small, mostly in the 2 ft to 3 ft range, with short periods around 8 to 9 seconds. The combined energy is weak to moderate, nowhere near enough to get the heart pumping. The wind is a mixed bag, offering some clean moments, but the surf just isn’t there.
We start to see a bit more size roll in around the 29th of August. On Saturday morning, Trestrignel sees a jump to 7 ft from the WSW, but the combined energy is still only moderate (426). The issue is the wind is a fresh 35 km/h cross-off, which will make it bumpy. It won’t be the clean, classic Trestrignel we’d hope for. The water temp is about average for the time of year, nothing weird going on.
Things get interesting on Sunday the 30th of August. The morning shows 7 ft from the west with a period stretching to 10 seconds. The combined energy climbs to 723, which is getting up there. The wind is a moderate 20 km/h from the SSW. It’s still not the ideal direction, but the energy is notable. This is the first real chance for something half-decent, but it’s not for beginners at this size.
The real standout, the one to mark on your calendar, is shaping up for Thursday, the 10th of September. This is the top of the outlook. We’ve got 7 ft of west swell, period up to 10 seconds, and the combined energy is a solid 799. But the kicker is the wind: a gentle 15 km/h from the southwest, blowing cross-offshore. That’s clean. That’s the kind of glassy, lined-up morning that makes the whole wait worthwhile. This is the one to keep an eye on, though it’s a long way out, so the details could shift.
Before that, on Monday morning the 7th of September, there’s a potential window. 5 ft from the WNW with a 25 km/h cross-off wind. The energy is moderate (471). It’s a decent option for a surfer who can handle a bit of push, but it’s not as crisp as the 10th.
Tuesday the 8th and Wednesday the 9th of September look too big and messy for paddle surfing. The swell jumps to 8 ft to 8 ft with strong cross-onshore winds and choppy conditions. Those days are better left to the kite surfers.
So, to sum it up, we’ve got a long, slow start. The surf is poor through the end of August and into early September. The best bet on the horizon is the morning of Thursday, the 10th of September for clean, solid waves.

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.
