The Lowdown

Alright, Rusty here again, translating that into feet and miles per hour. Same story, different numbers. The outlook for Trestrignel is grim for paddle surfing.

From the start of September right through the 4th, you’ve got onshore and side-shore winds ruining waist-to-chest high swell. Wave energy builds through the low to mid-hundreds (80 to 432), but the wind is just making a mess of it. This setup is better for kite surfing than a paddle on those afternoon winds.

Your best shot comes on Saturday the 5th of September. The morning looks clear with a light north-easterly cross-onshore and a solid 5ft of WNW groundswell with a long 11-second period. The combined swell energy is a strong 521. That’s got some push, but for a beginner-friendly spot like this, that long period groundswell might just close out on the sandbar. It’s a marginal call but the best we’ve got. The water is a touch warmer than normal at 19°C. The afternoon turns lumpy again, so hit it early.

Sunday the 6th and Monday the 7th drop off. Sunday morning is clean but tiny, with a weak 2-3ft swell and very low energy (125). Surfable but ordinary. Monday the 7th has a very long 14-second period and energy of 500, but a westerly cross-onshore wind at 9-12 mph kills the quality. A big tease.

For the rest of the first week and all the way to the 17th, it’s mostly cross-shore chop and onshore wind. The 14th of September (Monday) morning has dead glassy conditions with a 3ft swell and 231 energy—clean and small for a longboard, but nothing special.

The 17th of September (Thursday) morning gives you a 4-5ft WNW swell with an 11-second period and 373 energy, along with a gentle north-easterly side-shore. That's the most interesting session in the second week, but still not a standout.

Overall, Trestrignel is having a flat and frustrated spell. There are no true standout days. The morning of the 5th is your only real window, and even then it’s a gamble. A long, poor run like this is pretty normal for a sheltered spot that needs the right wind. Conditions can change, but right now, it’s a waiting game.

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.
