The Lowdown
Alright, folks – Rusty here. Let’s take a look at the next couple of weeks around Trestrignel. Honestly, straight out of the gate, we’re looking at a pretty bleak picture. The wind is a mess for days, and the surf is mostly junk. You’ll be lucky to get a few clean windows.
The first real highlight, and really the only one that stands out until the very end, is the morning of Monday the 14th. It’s not a monster swell, but for a session that’s actually surfable, this is the one. We’ve got a 3 ft swell from the west, with a period of 10 seconds, and the combined wave energy is a weak 184 (moderate). The wind is a light offshore from the southwest at 9 mph, which will keep it glassy and clean. The water is 65°F with an anomaly of 3°F, so it’s a touch warmer than usual for this time of year. The crowds here are always present, so don’t expect solitude. It’s a fairly consistent beginner spot, and this little window is about as good as it gets for a while.
After that, we hit a big gap. The next few days are riddled with onshore winds and poor conditions. The morning of Tuesday the 15th has a clean offshore wind from the SSE at 9 mph, but the swell is only 2 ft from the west, with a period of 8 seconds. It’s weak, small, and the energy is a very low 112 (weak). It’s surfable, but you’ll be scratching for waves.
Things get a bit more interesting later on, but the quality is still a problem. The morning of Wednesday the 23rd is the standout for the second week. We’ve got a 5 ft swell from the WNW, with a 10-second period, and the combined energy is a solid 458 (moderate). The kicker is the wind: it’s glassy, with a 9 mph offshore from the NW. That’s going to be clean, lined-up waves. The swell direction is from the WNW, which is a bit west of the optimum swell direction of NW, but it’s good enough. This is the one to circle for a proper session, but remember it’s a long-range call, so it’s a promising prospect but not a guarantee.
The rest of the second week is a write-off, with onshore winds and poor conditions dominating. The morning of Thursday the 24th has a clean offshore wind from the SSE at 10 mph, but the swell is only 4 ft, and the energy is a weak 359 (moderate).
So, the overall story is grim. A few tiny windows on the 14th and 15th, then a massive gap until the 23rd, which is the only true standout. If you’re a beginner, the 14th might be your best bet. For everyone else, hold out for the 23rd and hope the forecast holds.
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.
