The Lowdown

Yeah, folks, Rusty here. Let’s have a look at the charts for the next couple of weeks for our stretch of coast. It’s a bit of a mixed bag, and to be honest, there’s a whole lot of nothing on offer for the first stretch. We’re looking at a run of poor conditions that’s going to test your patience.

The opening week is a write-off. From Wednesday the 9th through to Friday the 18th, it’s all cross-onshore winds and choppy, messy surf. We do see some size on the 9th, with a 6ft swell pushing in from the WNW with a 9-second period, but it’s marred by that moderate cross-onshore breeze. The combined energy is moderate at 576, but the surf quality is poor. It’s just a messy, bumpy ocean. Don’t get too excited about the smaller windows either, like Thursday the 10th when it drops to 3ft and goes clean, but the energy is weak at 135, and it’s just not worth the paddle. We see another pulse on Friday the 11th, with 5ft of WNW swell and 464 energy, but again, that 9 mph cross-onshore wind just chops it all up. The whole week is a consistent let-down, with every single check showing “poor surf conditions.” It’s frustrating, but it is what it is.

There’s a bit of a lull in size and energy around the 17th and 18th, with the swell dropping to under 2ft and energy falling to below 100. That’s just flat, weak, and not worth your time. That stretch of nothing runs right through the middle of the period.

Now, for the one true standout. Mark your calendars for Saturday the 19th of September. The morning is the one to be there. We finally get a break in the clouds and, more importantly, a period of glassy conditions. The wind drops to next to nothing, and the ocean turns to glass. The swell is a clean 5ft from the WNW with an 11-second period, giving the waves a bit more push. The combined energy is a solid 446. The forecast even calls for “good surf conditions.” This is the one. Trestrignel is fairly consistent and a sheltered spot, but with these offshore winds and glassy conditions, it’s going to be magic. The crowd will be there, it’s always busy, but this is the morning to get it. This is the standout of the whole run.

After that, things get a little more ordinary again. Sunday the 20th has some cleaner conditions with a cross-offshore breeze, but the swell is smaller at 3ft. There’s another pulse of swell on the 22nd, but it’s a short-period, windswell from the NE, and the energy is weak to moderate. It’s just not going to have any shape to it. Then on the 23rd, we see a very long-period groundswell from the WNW, hitting 15 seconds and 3ft, with the morning glassy and calm. The energy is moderate at 373. It’s surfable, but with that long period at a beach break like this, it might be a bit too straight. Still, if you’re desperate, that Wednesday the 23rd morning is your other chance.

So, the long and short of it: suffer through the first ten days, and get after it on the morning of the 19th. That’s where the magic is. That Saturday, the 19th, is the one you want to free up.

Stay stoked, and I’ll see you out there.

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.
