The Lowdown
Hey, Rusty here. Let’s call it how it is – this stretch of coast is in a flat, frustrating rut. We’ve got a long stretch of "poor surf conditions" lined up, so don’t rush to get wet.
Starting at Trestrignel, the water’s a touch warmer than normal for the season at 67°F. The pattern kicks off weak and stays that way. From Thursday the 13th through Sunday the 16th, we’re seeing small, short-period waves around 2ft to 4ft, with low to moderate energy (71 to 263). The wind is mostly cross-onshore, leaving the surf choppy and messy. No joy there.
Monday the 17th is the flattest of the lot – swell drops to 1ft to 2ft, with energy bottoming out at 21. It’s a proper dead spot. Then we get a slight bump around Tuesday the 18th, but the swell is still weak and short-period (7 seconds), and the wind stays cross-onshore.
Things try to pick up from Wednesday the 19th. We see wave height climb to 5ft to 8ft by Thursday the 20th, with a long-period groundswell of 11 seconds and energy jumping to 1311. That’s the biggest pulse of the whole forecast. But – and it’s a big but – the wind is still onshore or cross-onshore, and conditions are still rated poor. That size and period with onshore wind just makes for a blown-out mess best left to the experts or kite surfers.
From the 21st to the 28th, it’s more of the same. Swell stays small to moderate, but the wind is unreliable. We get a few cleaner moments on the 22nd, 23rd, and 24th mornings with light cross-offshore breezes, but the swell is tiny – 1ft to 3ft – and energy is low. The 27th and 28th see a bit more size (5ft to 7ft) and moderate energy (297 to 632), but with fresh cross-shore winds and lumpy conditions, it’s not going to be clean.
Bottom line: if you’re desperate, the cleanest windows are on the 22nd, 23rd, and 24th mornings, but you’ll be on knee-high dribble. The bigger swell around the 20th is big and messy, and the 27th to 28th is lumpy. There’s no standout session here. Sometimes it’s a waiting game, and this is one of those times.
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.
