The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for our local stretch.
Mate, I’ve got to be straight with you – this is a grim run ahead. The whole 16-day window is a write-off for decent surf. There’s not a single session that gets the nod from the forecast. We’re looking at a solid blank from now through to the end of the month.
The only spot in the mix is Trestrignel, and it’s a tough watch. The water is sitting at 67°F, which is a touch warmer than normal for this time of year – not a bad thing, but it’s the only positive note.
From Wednesday 12 August onwards, it’s a story of small, weak, and messy swell. The wave energy is mostly weak, with values like 112 (weak) on Wednesday afternoon, and it rarely climbs above moderate. The best of a bad lot is around Thursday 20 and Friday 21 August, when we see the swell bump up to about 6 ft from the WNW, with energy readings of 463 and 464 (moderate). But even then, the wind is all wrong – onshore and cross-onshore, making it choppy and poor. The period is around 9 seconds, so it’s not groundswell, just weak wind swell.
The whole period is plagued by onshore and cross-onshore winds, mostly from the NW and WNW, with speeds ranging from 9 to 22 mph. It’s going to be choppy, lumpy, and generally unpleasant. There’s a brief moment on the morning of Saturday 15 August when the wind goes onshore, but it’s still 4 ft, short period (8 seconds), and the energy is only 195 – it’s not going to save the day.
Honestly, this setup is more interesting for kite surfers than paddle surfers. The waves are small, the wind is strong, and the quality is just not there. If you’re a beginner, it’s not worth it – the swell is too big on some days, but the conditions are so poor it doesn’t matter. For experts, it’s a no-go.
We’ve got a long gap of nothingness. Forecasts can change, but right now, I’d say save your energy and wait for a better window.
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.
