The Lowdown
Alright folks, Rusty here. Let’s break down what’s in store for Trestrignel over the next couple of weeks. I’ll be honest with you – it’s a rough patch, but there’s one tiny window that might just save the trip.
We’re looking at a long, quiet stretch to start. From now all the way through the 20th of September, it’s pretty grim. The wind is mostly onshore or cross-onshore, and the ocean is getting chopped up. Even when the swell bumps up to 7ft to 8ft on the 18th with a ton of energy in the water (1003 to 1380), the wind just kills it. The wave comment says it all: poor surf conditions. For a beginner spot that’s sheltered, seeing that much NW wind is a deal-breaker. This is a period where you’re better off leaving the board in the truck.
Now, the one true standout is Monday, the 21st of September. That’s your best chance by far. For the Monday morning session, we’ve got clear skies and a light offshore breeze from the ESE at just 3 mph. That’s glassy, clean water. The swell will be a clean 4ft from the WNW with a long 13-second period. That’s proper groundswell energy (602 combined energy), and at that size, it’s ideal for the beginners and longboarders who love this place. The water temp is about average for this time of year, so no surprises there. Just keep in mind Trestrignel can get packed, and the crowds are listed as "always" present, so get out there early. The quality won’t last though – by Monday afternoon the wind swings onshore and the magic is gone.
After that little window, the rest of the forecast falls apart again. Tuesday the 22nd drops to tiny 2ft to 3ft, and by the 23rd and 24th we’re back to onshore wind and choppy, messy waves. The last week of the month looks small and clean, but there’s hardly any swell energy (down to 38 or 62 combined energy) and the wind, while cross-offshore, is blowing a solid 19 mph. That setup looks more interesting for kite surfing than paddle surfing, to be honest.
So to sum it up: sit tight through this weekend and the start of next week. Your only real shot at a decent wave is first thing on Monday, 21st September. After that, it’s back to waiting for a change in the charts.
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.

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.
