The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what Trestrignel has in store for us over the next couple of weeks. I’ll be straight with you – it’s a bit of a tough stretch for the most part. The opening week or so is pretty much a write-off with poor surf conditions, so don’t be in a rush to grab your board just yet.

We start off with nothing worth paddling out for. The first recommendation isn’t until Monday the 7th of September, and even that one is a bit of a gamble. The whole first week is plagued by onshore or cross-shore winds and lumpy, choppy conditions. There’s a short-lived pulse of bigger energy on Monday the 7th with a 6ft swell from the WNW, with a long period of 12 seconds. The combined energy hits a whopping 1024, so there’s real power in the water, but it’s still blowing onshore and the forecast is only marginal. It’s too big for beginners at 6ft, and the onshore wind will likely make it a mess for everyone else.

Things don’t really improve until the second week. We see a real gap from around the 8th up to the 13th where it’s just poor conditions or tiny waves. Tuesday the 8th afternoon has a 7ft swell from the WNW (combined energy 655), but again, it’s cross-onshore and choppy. That size is only for experts, and the wind is not on your side. Honestly, it looks more interesting for kite surfing than paddle surfing on those bigger, blown-out days.

Now, the one true standout in the whole 16-day window is Monday, the 14th of September. This is the one to circle on the calendar. We’ve got a clean 4ft swell from the west (Optimum direction is NW, so it’s close) with a lovely long period of 11 seconds. The wind is light and offshore from the east in the morning – that’s glassy conditions, and the water will be clean as a whistle. The combined energy is a solid 464, so there’s good push behind those waves. This is a classic, clean, long-period groundswell that will bring good shape, especially as Trestrignel is a sheltered spot. It’s a great size for most surfers, but keep in mind that long-period swells at a beach setup can sometimes break a bit straight. Still, with that offshore wind, it’s hands down the best session on offer.

Tuesday the 15th morning hangs in there with a 3ft westerly swell (period 11 seconds) and glassy offshore winds from the ESE, but the conditions are described as ordinary, and the energy is weaker at 242. Still, it’s a clean option. Then Wednesday the 16th has another clean morning with a 4ft WNW swell, period of 12 seconds, and light cross-shore winds, but it’s only rated as marginal.

So, to sum it up: the first week is mostly a washout. There’s a big, but messy, pulse of energy on the 7th and 8th which is only for the brave or the kite surfers. The real winner is on Monday the 14th, with clean, offshore conditions and a nice, long-period groundswell. The water temperature is 65°, which is a touch warmer than normal for this time of year, so you’ll be comfortable without a full winter suit.

Stay patient, and wait for that Monday session.

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.
