The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer for Trestrignel over the next couple of weeks.

Honestly, mate, it’s a pretty grim stretch ahead. The whole 16-day window is a bit of a bust for any decent paddle surfing. You’re looking at a long, long gap of poor to marginal surf, with hardly a standout to get excited about. The first real glimmer of something doesn’t pop up until the very end of the forecast.

We start off this Saturday, the 8th of August, and through the whole first week and into the second, the swell is tiny and the wind is mostly messy. Early on, you’ve got a weak 0.7 ft swell from the west with a period of 9 seconds, but the combined wave energy is only 14 – that’s weak. It’s just not worth getting wet. The water temp is about average for this time of year.

Day after day, the same story: small 1 ft to 3 ft west-northwest swell, with onshore or cross-onshore winds making things choppy. Even when the wind does turn cross-off from the east or southeast, the swell is still too small to do anything with. Tuesday the 11th sees a brief spike in energy to 121 (moderate) as the swell jumps to 4 ft, but it’s short-period windswell at 5 seconds, coming from the east-northeast with a fresh cross-shore breeze – lumpy and horrible.

Things pick up in size around the 19th of August, with swell heights hitting 6 ft to 6 ft from the west and west-northwest, but the wind is a solid 15-19 mph onshore from the northeast, making it a choppy, lumpy mess. The combined energy hits 407-460, which is strong, but the quality is poor. For a beach break like Trestrignel, that’s more of a kitesurfing setup than a paddle surfing one.

The only half-decent window appears on Friday the 21st of August. We get a 5 ft west-northwest swell, period of 9 seconds, with a clean cross-off wind from the east at 15 mph. The wave energy is a solid 400 (strong). It’s still only rated as marginal – not classic – but it’s the best the whole two weeks has to offer. If you’re desperate, that Friday morning is your only real shot. Crowds are always an issue at Trestrignel, so expect company.

After that, it fades back into small, weak surf through the 22nd and 23rd. A real lean spell, this one. Forecasts can change, but for now, don’t hold your breath.

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.
