The Lowdown

Alright folks, Rusty here. Let’s get into it.

Right off the bat, I’ll be honest with you – this next week and a half is a bit of a write-off for Trestraou. The surf is going to be flat or tiny, the wind is mostly onshore or cross-on, and the conditions are just messy. We’ve got a long stretch of poor surf, with nothing worth paddling out for from Saturday the 18th of July all the way through to late in the week of the 27th. There’s a real gap there, so don’t be holding your breath.

The only real window of interest shows up on Sunday the 26th of July. The swell bumps up to a solid 7 ft from the WNW, with a period of 8 seconds. The combined energy of all swells directed here hits 462 (moderate wave energy), which is the biggest energy we see in the whole forecast. The wind is cross-offshore from the SW and that makes for clean conditions. The swell is getting a bit big for beginners, but for the confident crew, this is the best we’ve got. However, don’t get too excited about the shape – a short period (8 seconds) swell like this can be a bit walled up and wonky at a beach break like Trestraou. It’s still the standout slot.

The next day, Monday the 27th of July, is still worth a look. The swell drops back to 4 ft but the period stretches to 9 seconds, and the wind is still clean and cross-offshore from the W. The energy is moderate at 262 (moderate wave energy). It’s a smaller, cleaner option if Sunday feels too big.

The water temperature sits at 64°F, with a tiny anomaly of 1°F, so it’s pretty much average for the time of year. Nothing wild there.

Later in the forecast, on Thursday the 30th of July, there’s a moment where the swell is 5 ft and the wind goes glassy from the W. The period is still short at 8 seconds, and the energy is moderate at 298 (moderate wave energy). The conditions are described as “surfable waves but very ordinary conditions,” so it’s not a standout, but it might be the only other chance to get wet without getting blown out.

Overall, don’t be expecting much. The best we’ve got is that Sunday the 26th of July with the biggest swell and clean wind. The rest of the week is a paddling event at best.

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.
