The Lowdown
Alright, Rusty here. Let's chew the fat on what Trestrignel's got coming.
Got to be honest with you, mate – this stretch looks like a write-off. For a break that’s sheltered from the main northwest swell, the wind just won’t quit. The whole 16-day run is a fight to find a single decent session.
We start on Thursday, September 3rd, with a messy, cross-offshore wind at 16 mph messing up the surface. Friday the 4th brings a bigger bump in swell (energy readings hitting the 400s), but the wind is just as bad, putting a chop on everything. It’s a tough watch.
There is one tiny window. Saturday morning, September 5th. The swell drops to about 5 ft from the WNW, but the period stretches out to a sweet 12 seconds – that’s proper groundswell. The combined energy is strong at 774. More importantly, the wind goes light and glassy from the NE at just 3 mph. For a few hours, Trestrignel could clean up and look good with a light texture. The call says it’s marginal, so don't expect perfection. But if you’re keen, dawn patrol Saturday is your best and only real shot in the first week.
Sunday morning, September 6th, is another tiny window. The swell drops to 3 ft with a moderate 10-second period and a light SSE offshore wind at 9 mph. Water temp is 65°, which is a touch warmer than normal. It’s clean, but very small.
Then we get hammered. Monday and Tuesday (September 7th and 8th) see a big pulse of northwest swell, hitting 7 ft to 10 ft with very strong energy (over 1000 in the readings), but the wind is howling cross-onshore at 16 mph. That’s going to be a total mess – too big for a beginner and blown out for everyone else.
The mid-week from September 9th to the 12th shows a slow drop in size, but the wind is a persistent problem – mostly cross-onshore or onshore, with chop.
The second week, from September 13th onward, is basically flat with poor wind. The swell dips under 3 ft, and the energy readings are weak, often under 200. By September 17th and 18th we’re looking at ankle-slap (1 ft) with light winds, but it’s not worth the paddle.
Honestly, this is a blank run for Trestrignel. It’s a sheltered spot that needs a perfect combo, and we don’t get it in this 16-day window. For most of it, the onshore winds make it look more like a kite spot than a surf spot. If you’re itching, the only chance is that Saturday morning (Sept 5th) dawn patrol – it’s the only time the waves might be rideable.
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. 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.
