The Lowdown
Alright folks, Rusty here. Let’s get into it.
Alright, it’s not looking great for the next couple of weeks. We’ve got a long stretch of poor surf ahead, so you might want to leave the boards in the garage for a bit. The first real chance of anything rideable doesn’t show up until the second weekend.
The main spot on the radar is Trestraou. It’s a sheltered setup, so it needs a specific angle to work, and we’re just not getting it. The optimum swell direction is from the WNW, which is what we’re seeing for most of the period, but the energy is just too weak and the wind is all wrong.
Tuesday, August 4th through Monday, August 11th – it’s a total write-off. The swell is tiny, barely scraping 2 ft at best, with periods all under 9 seconds. The wind is mostly cross or cross-onshore, making everything a choppy mess. The combined energy is pitiful, sitting in the low two-digit figures most days. You’re looking at 12-19 mph breezes shredding what little bump there is. Not worth getting wet.
Tuesday, August 12th – there’s a brief moment of glassy conditions in the morning, with a 1.0 ft, 10-second swell. But it’s tiny. The combined energy is just 22 (weak), so it’s barely a ripple. For the truly desperate, maybe a longboard session, but honestly, it’s a pass.
Wednesday, August 13th and Thursday, August 14th – the swell picks up a little to 3 ft, but the period stays short at 8-9 seconds, and the wind is back to being cross or cross-onshore. The combined energy is still under 100 (weak). The surf is poor and messy.
Now, Saturday, August 15th is the one bright spot. The morning shows a 5 ft swell from the west, with a 8-second period, and clean cross-offshore winds from the west at 12 mph. The combined energy jumps to 294 (moderate). It’s the biggest and cleanest we’ll see in the whole window. The afternoon sees a 5 ft from the WNW, but the wind swings cross-shore, losing that clean face. The morning is the pick of the batch. The water temperature is about average for this time of year, so no surprises there.
Sunday, August 16th drops back to 4 ft with a 7-second period and cross-offshore winds in the morning. It’s clean, but the energy is only 170 (moderate). The wind is light, so it’ll be workable, but it’s a step down from Saturday.
Monday, August 17th through Wednesday, August 19th – we see a few more clean windows with cross-offshore winds, but the swell is inconsistent. The 18th and 19th have 4 ft swells with moderate energy (151-239), but the periods are short at 6-8 seconds, so the waves will lack push.
Honestly, the only standout is Saturday morning, August 15th at Trestraou. It’s not a classic, but it’s the best we’ve got. The rest of the fortnight is a right-off. For a sheltered spot, we need a lot more consistent, longer-period groundswell to make it work. This stretch of weather is just flat and windy. It’s a tough one.
Rusty.

Information about the Trestraou Surf forecast
The above surf forecast table for Trestraou provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu. Our Trestraou 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 (Trestraou) 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 Trestraou 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.
