The Lowdown

Alright, crew, Rusty here. Let's break down the next couple of weeks for Trestrignel. I'll be honest, it starts off real slow, with a flat spell that'll test your patience.

We're looking at a big gap from the 20th through the 25th of August with nothing to ride. The data's full of "poor surf conditions"—the wind is ugly, and the swell is all wrong from the WNW for this sheltered spot that needs a pure NW angle. The water's a little warm for the season at 19°, but that's about the only good news.

The first real sign of life comes on the 26th of August, but it's tiny. A 2ft swell from the WNW with a period of 9 seconds. The wind is offshore, which is a massive plus, so it'll be glassy, but the energy is weak (101). We're just getting wet, not surfing.

The real standout is Sunday, the 30th of August. The morning session is the one. We've got a solid 6ft swell from the west with an 8-second period. The wind is a light offshore, creating clean, peelable waves. The energy is moderate (481), and the report says "expect good surf conditions". That's your window. The morning of the 1st of September is also promising with a 6ft WNW swell and light offshore winds, but the period is a touch longer at 10 seconds.

The 31st of August has a massive 10ft swell, but it's got strong cross-shore winds and a lumpy sea state. That's for the tow-in crew or the kite surfers, not for a standard paddle. For a beginner spot like Trestrignel, anything over 5ft is getting heavy, so that 10ft day is a hard pass.

So, sit tight this week, get your gear ready, and pencil in the 30th of August. That's the best we've got.

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.
