The Lowdown
Alright, this is Rusty. I’m gonna level with you. The whole 16-day outlook for this wave is a total bust. There’s not a single session that’s worth getting wet for. Every time slot is nothing but poor surf conditions.
We kick off on Monday, August 3rd, with a tiny 2ft swell from the west, a weak 8-second period, and a cross-on breeze. The combined wave energy is a measly 53 (weak). The water’s at 66°, which is a touch warmer than normal for this time of year, but that’s the only thing that’s slightly interesting. The wind is light though, coming from the west at 6 mph, but it’s still cross-on, ruining any hope of a clean wave.
Tuesday the 4th sees a little bump to about 3ft, but the period is still short and the wind picks up to 12–19 mph from the west and southwest. The cross-off wind on Tuesday morning might clean the face, but the swell is weak and the energy only reaches 123 (moderate). Not worth the hassle.
Wednesday the 5th is the biggest swell of the whole run, with about 6ft from the west and a cross-shore wind at 16 mph. The combined energy jumps to 454 (moderate energy), but with that wind direction and a short period of 8 seconds, it’s going to be a lumpy, cross-chop mess. This is one of those days where the setup looks more interesting for kite surfing than paddle surfing. The size is over 5ft, so it’s a bit much for beginners, but the quality is so poor it wouldn’t matter.
From Thursday the 6th onwards, it’s a slow, painful decline. Swell drops below 4ft, periods are short, and the wind just keeps blowing cross-on or onshore. The second week is even worse. The energy numbers sink into the 20s, 30s, and even single digits by the 17th and 18th. On August 16th, the swell is a pathetic 0.7ft with a combined energy of just 9 (weak). You’d be better off sitting on the beach.
I’m not gonna name a single standout because there isn’t one. Trestrignel is a sheltered spot, and the optimum swell direction is from the northwest, but the wind and swell never align. It’s a blank run. For this area, a stretch like this is more normal than a surprise. Keep an eye on the forecasts, but for now, the boards stay in the shed.
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.
