The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way for Trestrignel. Gotta be straight with you – the next two weeks are a real mixed bag, and there’s a lot of waiting involved. The good news? There’s a couple of standout windows if you’re patient.

The Big Picture

Right off the bat, we’ve got a long, frustrating stretch. From now through Saturday the 28th, the conditions are just plain rough. Onshore winds and cross-chop are the main story, with surf quality getting a big thumbs down. You’ll see some decent sized swell in there – we’re talking 7ft from the WNW on Wednesday the 16th with moderate wave energy (885), but it’s all blown out by strong NNW winds. Same goes for Friday the 18th; there’s a big 7ft groundswell hitting with a long 13-second period and strong energy (1344), but again, the wind destroys it. Not worth paddling out for anything but a beating.

There's a brief glimmer early on Saturday the 19th morning – 5ft from the W with a short 8-second period, and the wind goes cross-offshore, making it clean. It’s a marginal call with questionable tide, but honestly, that’s the best looking wave all week. The energy is weak (499), so don’t expect much push. The rest of that weekend and the following week remain poor to marginal.

Then we hit another major gap. From Monday the 23rd afternoon through to Saturday the 28th, it’s all poor surf again. The swell drops off hard, getting down to 1ft by the 26th – basically flat with zero energy (39). The wind stays messy.

The Standout

Now here’s the one you’ve been waiting for. Mark your calendars for Sunday the 27th of September. It’s the first proper hope we’ve had in a while. The morning session is the clear winner. We’re looking at a clean 3ft groundswell from the WNW with a very long 14-second period. The energy is moderate (544), and the wind is light and offshore from the east. That’s going to produce some beautiful, glassy waves. With that long period, Trestrignel, being a sheltered spot, should handle it well. The shape will be clean, the sets will have proper power, and paddling out will be easy between sets. It’s not huge, but it’s quality.

Now, a quick note on the water: when you’re out there on the 27th, the water temp is running about average for this time of year, so your usual spring suit will do.

The Rest

Don’t get excited about the Sunday afternoon session – the wind swings onshore from the NNW and kills it. The following Monday and Tuesday return to poor, unfavourable conditions. The forecast for the very end of the window, Wednesday the 1st of October, shows a tiny 2ft swell with strong cross-shore winds and messy chop. That’s a write-off.

So, the call is simple: if you’ve got the patience, wait for Sunday morning the 27th. That’s your best shot at clean, fun waves. Everything else in this two-week stretch is either blown out or flat.

Rusty.

Information about the Trestrignel Surf forecast

The above surf forecast table for Trestrignel provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestrignel can be found by selecting the local surf guide option on the grey menu. Our Trestrignel surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Trestrignel) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
