The Lowdown

Alright, surfers, Rusty here. Let's talk about what's cooking at Trestrignel. We've got a bit of a mixed bag over the next couple of weeks.

First up, the water temperature is sitting at 67°, which feels a touch warmer than normal for this time of year, so you might get away with a thinner suit.

Right off the bat, we're looking at a run of pretty ordinary conditions. For the next couple of weeks, the wind’s all over the place and the surf quality is just not there. We have a gap from now until late in the first week of September where there just isn't anything worth paddling out for. It’s a long stretch of flat or junky, wind-blown waves.

The first real glimmer of hope shows up on Thursday, August 27th. The morning is going to be our best shot in a while, with a clean 4ft swell from the west, light winds, and some moderate wave energy (300). It's surfable, but don't expect perfection.

Things get a bit more interesting towards the end of the month. On the 28th of August, we see a bit of a bump, with a 6ft to 7ft west swell rolling in. It's clean with a cross-offshore breeze, and wave energy is building (628 to 656). It won't be epic, but it's a lot better than what we've been seeing.

Now, the big one. The standout in this whole outlook is the morning of the 4th of September. That Friday is looking promising with a 7ft swell from the northwest. It's clean with a light cross-offshore breeze and a solid 485 of combined swell energy. It’s going to be punchy. Because it’s over 8ft, this one is for the experienced crew. Beginners should sit this one out. The swell direction from the northwest isn't a perfect match for the optimum direction here, but the clean conditions and size should still give us some decent walls.

Right after that, on the afternoon of the 4th, the size drops back down to 4ft and the wind shifts cross-shore, so don’t expect the quality to last.

So, there you have it. A long dry spell, one promising morning later in August, and one standout for the experts in early September. Keep your eyes on that 4th.

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.
