The Lowdown
Alright folks, Rusty here. Let’s have a look at what Trestrignel has in store for us over the next couple of weeks. I gotta be straight with you – it’s a rough run. There’s nothing in the finder that I can point to and say “go now.” The whole 16-day window is a write-off for decent surf. The first recommendation doesn’t even appear, so we’re looking at a blank from the start.
We kick off Sunday the 30th of August with a 5ft west swell, but a strong 16 mph cross-offshore wind from the SW is making a mess of things. The water is sitting at 66° – a touch warmer than normal for this time of year. The combined swell energy is moderate (371), but the report calls it poor surf conditions, and I can see why. That wind is just too much for this sheltered spot.
Monday the 31st sees the swell jump up to 8ft from the west, with a period of 10 seconds. That’s a lot of water for a beginner spot, and with a 19 mph cross-onshore from the WNW, it’s gonna be a lumpy, choppy mess. The energy is strong (1194), but the conditions are poor. Same story Tuesday, Wednesday, Thursday – a mix of cross and cross-onshore winds with inconsistent swell around 3ft to 5ft, and the energy drops right off. There’s just no window of clean, rideable surf.
Friday the 4th of September brings the biggest swell of the period – 8ft from the WNW with a 12-second period (groundswell). That’s a 1527 combined energy reading, very strong. But the wind is a moderate cross-onshore from the WNW again, and the surf quality is rated poor. For a beach setup like this, with that much swell and poor wind, it looks more interesting for kite surfing than paddle surfing. It’s going to be too big and messy for the average surfer.
The rest of the first week and into the second week is a sad story of small, weak swell – 2ft to 3ft – with periods under 10 seconds, often onshore or cross-onshore. The combined energy is weak, barely hitting triple digits. A couple of mornings (like Sunday the 6th and Monday the 7th of September) show clean conditions with cross-offshore winds from the SE and E, but the swell is tiny – 2ft to 3ft. You might get a knee-high ripple if you’re desperate, but it’s not worth paddling out for.
Looking further out, around the 12th and 13th of September, we get a fresh cross-shore wind from the ENE at 16 to 19 mph, with a long-period 12-second west swell, but the height is only 2ft to 3ft. The energy is weak to moderate, and the wind is creating a lumpy cross-chop. Not a good combination.
So, the bottom line: there is no standout, no good session, no reason to rush down to Trestrignel in this 16-day window. The forecast is a long, dry spell. It’s one of those periods where the area just doesn’t deliver. Forecasts can change, but as it stands, keep your board in the car and wait for a better day.
Rusty.
