The Lowdown
Alright, Rusty here. Let’s break down what Trestrignel has for us in the coming days.
First things first – there’s a big dry spell before we get anything worth paddling for. From now right through the end of this week and into the start of next, it’s mostly a bust. The wind is consistently cross-on or onshore, making a mess of things. We’ve got some swell, but the wind kills it. The first real chance doesn’t come until Monday, September 14th.
That Monday morning (14th September) is our opening. The swell drops to about 3ft from the west with a 9-second period, and the wind turns light cross-offshore from the southwest. It’s clean. The water’s at 65°, which is a touch warmer than average for the season – not bad. The energy is weak, so don’t expect much push, but for a small, clean session on a longboard, this is the best we’ve seen in days.
After that, it’s back to poor conditions until we hit the real standout: Monday, September 21st. That morning brings a solid 8ft swell from the west-northwest with a long 13-second period, and the wind is cross-offshore from the southwest. This is a proper groundswell with serious power – the combined energy reading is 2359. These waves will have some punch, but at a beach break like Trestrignel, that long period might make them a bit walled-up. Still, for the experienced surfer, that Monday morning session is the best bet of the whole forecast. By the afternoon, the wind goes cross-shore and it gets lumpier, so get out there early.
The following Sunday (27th September) also shows some size – 7ft from the west-northwest with a very long 14-second period – but the wind is cross-on and blowing a strong 35 km/h. That’s a choppy mess. The energy is huge (2440 combined energy), but honestly, that setup looks more interesting for kite surfing than paddle surfing.
So, in short: skip this week. Mark Monday the 21st on your calendar. A powerful groundswell with clean morning wind – it’s a ways off, so keep an eye on it, but it’s the one to aim for.

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.
