The Lowdown
Alright, Rusty here again. Let’s talk Trestrignel in feet and miles per hour.
The water’s sitting at about 66°F, which is a touch warmer than normal for this time of year – you’ll be fine in a shorty or spring suit.
Right, the next 16 days are a real mixed bag, and mostly a struggle. The swell energy comes and goes, but the wind’s working against us most of the time. The one standout, and the best on offer, is Saturday the 5th of September. We’ve got a solid WNW groundswell at about 5 feet with a period of 11 seconds, carrying moderate energy (505). The wind is light from the NW, giving us clean, glassy conditions. That’s the one to aim for – not huge, but clean and lined up.
Before that, there’s a long stretch of poor conditions. Sunday the 30th of August has a 5-foot W swell but the wind is a cross-off from the SW at 22 mph, keeping things messy. Monday the 31st is bigger – around 8 feet from the west – but it’s cross-on and lumpy, with strong energy (1218). Too big for beginners, and the chop ruins it for everyone.
The 1st of September has a 4-foot W swell with light SW cross-off wind, but it’s just ordinary. The rest of the first week is a slog – onshore winds, cross-chop, and short-period swell. The 4th of September shows a 6-foot WNW swell with 11-second period and moderate energy (866), but it’s cross-shore with a lumpy mess.
After the 5th, it drops off. The 6th of September morning has a clean 3-foot WNW swell with light ESE cross-off wind, but it’s tiny. The 7th is flat at 2 feet. The 8th through the 10th is a write-off with fresh winds and under 3 feet. The 11th sees a 5-foot W swell but onshore and lumpy. The 12th of September morning offers a slight chance – 3-foot W swell, slight air, clean – but it’s ordinary.
After that, it’s weak and messy right through to the 14th. So, bottom line: Saturday the 5th of September is your best bet. Otherwise, it’s a long wait.
Rusty.

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.
