The Lowdown

Alright, let me break it down for ya. It’s Rusty here, and I’ve got the full lowdown on Trestraou for the next couple of weeks. I’ll be straight with you – it’s a rough patch ahead. The whole 16-day window is pretty grim, with the first decent surf not showing up until the 12th of August, and even then, it’s nothing to write home about.

Right out of the gate, from Thursday the 6th of August all the way through to the 11th, we’ve got a massive gap of almost no surf. We’re talking ankle-snappers at best, with swell heights barely cracking 2ft. The wind is mostly cross-on or onshore, so it’s choppy and messy. Not worth paddling out for.

Things start to stir on the 12th of August. Wednesday morning we see a small bump, 2ft from the west, with a period of 10 seconds. The combined energy is still weak, just 98, but it’s a start. The wind is light and cross-on, so there’ll be some small wind ripples. By Wednesday afternoon, the swell picks up a bit to 3ft from the west, period dropping to 9 seconds, and energy hitting 147 – that’s moderate. Still cross-on wind though, so it’ll be a bit choppy. Not great, but it’s the first real chance to get wet.

The standout, if you can call it that, is Thursday the 13th of August. Thursday morning we get a 4ft swell from the west, with a period of 11 seconds – that’s a long-period groundswell. The combined energy jumps to 272, so there’s some proper push behind it. The wind is light and cross-on, so it’ll be bumpy but not a total washout. This is your best bet for the whole period, but it’s still only marginal. The water temp is around 66°, which is about average for this time of year.

Friday the 14th of August sees the swell drop back to 3ft, period down to 9 seconds, and onshore wind from the north-northeast. It’s not clean. The weekend of the 15th and 16th stays small and choppy, with short period windswell and cross-shore breezes. Not worth getting excited about.

The following week, around the 17th and 18th of August, we get another pulse. Monday the 17th has a 4ft swell from the west with a 9-second period and energy of 235 – moderate. But the wind is onshore and moderate, making it messy. Tuesday the 18th is similar, but the swell drops to 2ft.

Then, things get weird. On Wednesday the 19th of August, we get a 5ft swell, but it’s coming from the east-northeast with a short, weak period of 6 seconds. The wind is cross-offshore and clean, which is a positive, but the swell direction is all wrong for Trestraou – it’s sheltered from that angle. The combined energy is moderate at 138. It’s clean, but the waves will be weak and wonky. Thursday the 20th sees a similar setup, with a 5ft east-northeast swell and strong cross-offshore winds. The energy is 164. For kite surfers, this clean wind and small chop might look interesting, but for a paddle surfer, it’s a frustrating combo.

After that, the 21st of August drops right back off to 2ft with lumpy cross-shore wind. The whole period is a write-off. There are no true standouts here. The best of a bad bunch is the morning of the 13th of August – that 4ft, 11-second groundswell with light wind. It’s not going to be perfect, but it’s the most energy we’ll see.

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.
