The Lowdown

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

Well, it’s a bit of a tough stretch for Trestrignel, to be honest. The wind is just not playing ball for the most part, and the surf quality is pretty ordinary. The water temperature is sitting at 66°F, which is pretty much what you’d expect for the time of year.

The first decent chance we get is on Wednesday, August 19th, in the morning. There’s light rain and a cross-offshore breeze, so the surface will be clean. Swell is a modest 4ft from the WNW with a period of 7 seconds, and the combined energy is moderate at 143. It’s surfable, but far from a classic.

Things don’t really improve. Thursday the 20th sees a jump in swell size to 6ft – 6ft from the WNW, with moderate energy (534), but that cross-onshore wind just chops it up. Friday the 21st has a clean offshore wind from the NNW, with 5ft of WNW swell (322 energy), which is promising on paper, but the word on the water says it’s poor surf conditions. Hard to get excited.

There’s a real lull from Saturday the 22nd through to the end of the month. The swell drops right off, and the wind stays messy or strong. Tuesday the 25th has a morning window with a clean offshore wind and 5ft of swell from the NE (227 energy), but it’s not the ideal direction for the break.

The best looking period on the whole forecast is right at the end. Monday, August 31st has a big 8ft swell from the WNW with a very long period of 13 seconds. That’s a powerful groundswell with combined energy at a massive 2636. The wind is only a gentle cross-onshore breeze, so it will be a bit bumpy but the power is there. This is an expert-only kind of day with the size and long period, and it’s going to be a bit straight at this beach break, but the energy is undeniable.

Then Tuesday, September 1st morning has a similar sized 8ft WNW swell, still with that 13-second period (energy 2091), and a strong cross-offshore wind from the SSW. That’s actually a cleaner look, but the wind is strong at 25 mph, so it’ll be a battle. That’s the standout of the 16 days, but it’s a long way out and the confidence is lower. For now, keep your eyes on that last week of August and the first of September.

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.
