The Lowdown
Alright, Rusty here. Let's have a look at what we've got for Trestrignel over the next couple of weeks. It's a sheltered beginner spot, but honestly, for the vast majority of this run, it's looking pretty grim. The wind is just a constant problem, swinging onshore or cross-onshore day after day, messing up what little swell there is. The water is sitting at 65°F, which is a touch warmer than normal for this time of year, but that's about the only good thing going for it.
The first real sniff of anything surfable doesn't come until Monday the 14th of September. On the Monday morning, the wind drops to a glassy calm (SSE at 3 mph). We've got a 3ft swell rolling in from the west with a 9-second period. The energy is weak, only about 176, but those clean conditions will make it look better than it is. It’s surfable, but very ordinary. That window shuts quick; the afternoon goes cross-shore and messy again.
After that, it's just a wall of poor conditions. Tuesday the 15th gets a bit of size, up to 6ft, but with a 22 mph cross-onshore, it's lumpy and choppy. Not worth it. Wednesday the 16th sees the biggest swell of the period, 7ft from the WNW, and the wind is actually straight onshore from the NNW at 19 mph. The combined energy is strong at 867, but with that wind, it's going to be a washing machine. That size (7ft) and onshore wind mean it's only for experts who don't mind getting thrashed.
There's a gap of total rubbish until we get to another small window. On Friday the 18th of September, the morning session shows a clean, cross-off wind from the SW at 9 mph. The swell is only 3ft, but the period is a nice long 12 seconds from the WNW, giving it some shape and a clean face. Energy is moderate at 346. It's still surfable but very ordinary, so a longboard or a funboard would be the call. The afternoon goes back to choppy.
Then it's another long stretch of poor surf. The wind just keeps hammering it. We finally get another tiny chance on Thursday the 24th of September. The morning looks glassy again with a 3ft, 12-second swell from the WNW. The energy is moderate at 320. It’s the same story – clean, small, and very ordinary. And then, on Friday the 25th of September, we get the best of the bunch. A light offshore breeze from the SSE at 3 mph, with a 6ft swell from the WNW at 8 seconds. The energy is moderate at 361, and the conditions will be clean. The size is getting up there for a beginner spot, but for the more experienced surfer on a groveler, this Friday morning is the standout of the entire outlook. The afternoon goes wonky again.
So, for a spot that's usually a learner-friendly wave, this is a rough run. The best you're looking at is the Friday the 25th morning for the cleanest, punchiest waves on offer, but even then, it's nothing special. If you're a kiter, the days with significant swell and strong cross-onshore winds, like the 15th and 16th of September, look far more interesting for your sport than paddle surfing.
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.
