The Lowdown
Alright folks, Rusty here. Let’s have a good look at what Trestrignel has in store for us over the next couple of weeks. I’ve got to be straight with you – it’s a bit of a mixed bag, with a whole lot of ordinary days before we finally get a glimpse of something decent.
First up, the water temp is sitting pretty average for this time of year, nothing out of the ordinary there. Now, for the surf... for the first week, it’s pretty grim. From Tuesday the 25th right through until Thursday the 27th, we’re looking at flat, weak, and messy conditions that just aren’t worth paddling out for. The combined swell energy is barely registering, with numbers like 159 and 21, so don’t even bother.
Friday the 28th morning actually shows a small bump of 5ft from the WSW, with light offshore winds from the SSE that will clean it right up. The swell energy is up to 206 (moderate), and it’s a gentle offshore breeze. That might be a small window for the beginners out there, as it’s well under 5ft, but it’s still a bit of a struggle to get excited about.
After that, it’s back into a rough patch. From the 28th afternoon through to the 4th of September, the wind is a major problem. We’ve got strong cross-shore and cross-onshore winds from the NW, W, and SSW, blowing 12 to 25 mph, turning the place into a lumpy, choppy mess. The swell does get up to around 7ft to 7ft, but with the wind on it, it’s just no good. The combined swell energy climbs into the moderate to strong range (416, 553, 702), but the quality is poor. It’s more of a kite-surfing show than a paddle-surfing session during that stretch.
Now, here’s the bright spot, and it’s a long way off. Sunday the 6th of September is our standout. On the morning, we get a nice 7ft swell from the WNW with a period of 11 seconds, blowing in from the south at 9 mph. That’s a gentle offshore wind, meaning clean, peeling faces. The combined swell energy is a hefty 979 – that’s strong, powerful stuff. The afternoon holds up too, with 6ft and the same clean offshore flow, though the wind picks up a bit to 16 mph. This is the one to circle on your calendar, but remember, it’s over a week away, so treat it as a promising prospect rather than a solid bet.
Monday the 7th of September is an absolute no-go. The morning is blown out with 31 mph NW winds, and the afternoon sees a massive 16ft swell from the WNW with an 18-second period, but with a strong cross-onshore wind and a combined energy of 16925. That’s a colossal amount of energy, but it’s raw, dangerous, and messy – strictly for experts or the suicidal, and even then, it’s not looking clean.
The final days, the 8th and 9th, drop back into marginal territory. The 8th has a 10ft swell with a long 13-second period from the W, and gentle cross-shore wind, but the quality is only marginal, and with that size and period, it’ll be breaking straight and fast at a beach break like this. Not ideal. The 9th is just more lumpy cross-shore chop.
So, the summary is this: a long, bleak first week, a clean but small window on the morning of the 28th, and then our real hope pinned on Sunday the 6th of September. Keep an eye on that one.
Rusty.

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.
