The Lowdown
Right, let’s get into it. Trestrignel’s our only spot on the cards here, and to be honest, it’s a pretty grim ride for the next couple of weeks. This is a sheltered little nook that needs the stars to align, and they’re just not lining up.
We’ve got a long, dry spell to start. From now until the morning of September 5th, it’s all poor surf conditions – messy winds, mostly cross or cross-onshore, and even when the swell bumps up, the quality just isn’t there. The water’s running a touch warmer than normal for this time of year at 67°F, but that’s about the only positive. The combined wave energy mostly sits in the “moderate” range, with a couple of stronger spikes – like the 1384 on the morning of the 31st of August when the swell pushes 8ft – but it’s all blown to bits by strong cross-shore winds. That 8ft stuff is expert-only territory anyway, and with the wind on it, it’s a messy battlefield.
The first real glimmer comes on Saturday morning, the 5th of September. Conditions turn glassy with light airs, the swell is a clean 4ft from the west with a 10-second period (that’s a nice long period, groundswell feel). The combined energy is 302 – moderate, but it’s the cleanest we’ve seen. This is the standout of the whole outlook. It’s a glassy window, and for a spot that gets crowded “always”, you’ll want to be out there early to grab a few tidy ones before it gets busy.
After that, it’s back to the grind. The afternoon of the 5th gets blown out again with onshore wind, and the following days are a mix of lumpy cross-shore chop and cross-onshore junk. The swell sticks around 3ft to 6ft, but the wind just won’t play ball. The second week is a write-off – a few clean-ish pockets on the 9th of September morning when the wind goes offshore from the SSE, but that 4ft west swell is weak and short-lived. The rest is messy.
Overall, there’s only one real session on offer here – that glassy Saturday morning. If you can make it, you’ll get the best of a bad run. Otherwise, it’s a waiting game.

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.
