The Lowdown
Alright crew, Rusty here. Let’s break down Trestrignel for the next couple of weeks.
Honestly, it’s a rough outlook. The whole 16-day stretch is mostly flat and poor. We’re talking days of tiny, weak waves with bad conditions. The first real pulse of size doesn’t show up until Saturday the 25th, but the wind is a problem.
The biggest swell event is around Saturday the 25th and Sunday the 26th, with waves pushing 5ft to 6ft. The combined swell energy on Saturday afternoon hits 344 (moderate energy), which is the most we’ll see. But the wind is cross-onshore from the WNW, right on the same direction as the swell, making it choppy and ugly. The period is short, around 6 to 7 seconds, so it’s just junky windswell. This beach break setup with the bumpy conditions looks more like a kite-surfing session than a paddle surf.
Monday the 27th offers a little more consistency, with energy around 122 (moderate energy) in the afternoon, with 3ft waves from the WNW, but again, cross-onshore wind and a short 8-second period. The shape will be weak and messy.
The water temp is about 64°F, which is normal for this time of year.
So, what’s the best bet? If I had to pick one, it’s the Wednesday morning of the 29th. The wind swings to a cross-offshore from the SSW, the wave comment says "clean", and the surf is a manageable 3ft from the WNW. The period is still short, but the clean conditions will make it far more rideable than the rest of the junk. It’s a beginner-friendly wave at that size, and at least you won’t be fighting the wind.
The rest of the forecast? A long, flat wait. Nothing worth getting excited about until that late July window, and even then, it’s messed up by the wind. The short-period swells and onshore winds are a stubborn combo.
Be patient, check the forecasts, and maybe bring the kite gear.
Rusty.

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.
