The Lowdown

Alright folks, it’s Rusty here. I’ve looked at the charts for our local stretch, and to be honest, it’s a pretty quiet run. There’s a long gap of flat, poor conditions before we see any real energy. We’re looking at Trestraou, and it’s a sheltered little nook, but the WNW swell that’s its best bet is just not showing up in any meaningful way for a while.

The first week is basically a write-off. From Monday the 20th of July right through to Sunday the 26th, we’ve got nothing but tiny, weak waves – the combined swell energy is struggling to hit even 50 (30-48). Winds are mostly onshore or cross-onshore, and the water is about average for this time of year. It’s ankle-snappers at best, with poor surf conditions across the board. You’re better off finding a flat rock to sunbathe on.

Then we hit Monday the 27th of July, and things finally start to stir. The wind swings around to a light, clean cross-offshore from the W, and we see the swell height bump up to 2ft from the NW. The combined energy hits 74 – still weak, but it’s something. It’s not a standout, but it’s the first time the ocean looks rideable. This pattern continues into Tuesday the 28th, with a 4ft WNW swell in the morning, building to 4ft in the afternoon. The energy jumps to 115 and then 206, and the winds are clean cross-offshore again. The period is short though, around 5-7 seconds, so it’s going to be a bit of a windswell bump, but it’s clean. For a spot that’s been dead, this is the best on offer.

The real standout, if you can call it that, is Wednesday the 29th of July. We get a 4ft WNW swell with a period of 11 seconds, pushing the combined energy up to 335. That’s a moderate energy pulse, and it looks like the most push we’ll see in the whole window. The problem is the wind is a cross-onshore from the N, which will chop it up a bit. Still, for size and energy, this is the peak. After that, it fades back into the 2ft to 3ft range with onshore winds, and the energy drops back into the 100s.

So, the honest truth: there’s no classic day here. The 28th of July with the clean cross-offshore wind and building 4ft swell is your best bet for a clean, surfable wave, even if it’s a bit short-period. The 29th of July has the most grunt, but it’s messier. The rest of the 16 days, from the 30th of July into the first week of August, is a slow fade back into weak, onshore slop.

Don’t get your hopes up too high for this one. The ocean is playing hard to get.

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.
