The Lowdown
Alright folks, Rusty here. Let's look at Trestrignel for the next couple of weeks. It's a mixed bag, so let's get into it.
Water temp is about average for the season.
We start on Friday the 11th, but it's a mess – a 5ft W swell with a 10-second period is getting hammered by a cross-on wind. The energy is moderate (470), but it's unsurfable. The whole weekend is pretty ordinary. Saturday the 12th morning offers the first real window: a clean 3ft W swell (147 energy) with a light cross-off breeze. It's not amazing, but you can get wet. Sunday the 13th is a write-off with strong cross-shore winds.
The best bet in the first week is Monday the 14th morning. The wind turns glassy from the SSE, going offshore, cleaning up that same 3ft W swell (176 energy). It's a beginner wave, but for a Monday dawn patrol it'll be fun and quiet.
After that, the wind blows onshore again until Friday the 18th morning. A solid, long-period groundswell from the WNW hits at 4ft with a 12-second period (619 energy). The wind is off from the SW, keeping it clean. That's a good option, but this spot is sheltered, and that long period can make beach breaks wall up. It's a marginal one.
There's a real gap in quality until Thursday the 24th. Thursday morning brings the biggest swell of the forecast: a solid 8ft WNW groundswell with a 12-second period. The energy is strong (1622), and the wind is clean from the east-southeast. This is only for experts – way too big for beginners, and the long period will make it punchy. If you're a local charger, this is your window. Friday the 25th morning is a step down at 5ft with clean wind, but the 24th is the one to circle.
Overall, it's spotty. You'll have to pick your windows of clean wind. The 24th is the only true standout for the experienced crew. For everyone else, keep your expectations low and your eye on the wind.
Rusty.

A general guide to surfing at Trestrignel can be found by selecting the local surf guide option on the grey menu.

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.
