The Lowdown
Alright folks, Rusty here. Gotta be straight with you – it’s looking like a tough stretch ahead for our shores. The next week and a half is pretty grim, with nothing really worth paddling out for. There’s a big gap of poor conditions from now until about the 26th of August, so don't hold your breath just yet.
We’re looking at a long dry spell through the end of August, but there is a glimmer of hope right at the end of the forecast window. The only date that’s got my heart beating a little faster is Sunday the 30th of August. We’ve got a nice 7 ft swell rolling in from the west, and the kicker is that it’s glassy. Dead flat, no wind. That’s rare. For that afternoon, it’s the one true standout, but keep in mind we’re talking about a long-range call, so it’s promising but not locked in.
Before that, there’s a flicker on Thursday the 27th of August morning – a small 4 ft from the west with a glassy surface, but the period is only 8 seconds. It’ll be surfable, but just barely.
The best bet overall across the whole 16 days is that Sunday the 30th glassy session at Trestrignel. With the swell coming from the west and the water temp sitting around 66°, which is pretty normal for this time of year, you’ll want to be there. But fair warning – this spot is always crowded, so get there early if you want a piece of it.
Otherwise, it’s a lot of nothing. Stay patient, and keep an eye on the sky.
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.
