The Lowdown
Alright, my friends, Rusty here with the hard truth. Looking at the next 16 days for Trestraou, it’s a grim outlook. We’ve got a massive dry spell kicking things off. From the 19th all the way through the 26th of July, there’s nothing but tiny, weak swell and poor conditions. That’s a full eight days of flat, choppy nonsense. Don’t even bother waxing up.
The first sign of life comes late on the 26th of July Sunday afternoon. The swell bumps up to 5ft out of the west, with a period of 6 seconds, and the energy hits a moderate 150. But the wind is cross-shore and the quality is still poor. It’s a false alarm.
The 27th of July Monday brings more size – 5ft in the morning, hitting 6ft in the afternoon – both from the WNW. The energy is strong (306 and 383), but the wind is cross-onshore and rough. It’s a powerful, ugly mess. Not what we’re looking for.
The best you’re gonna get is the 28th and 29th of July. Tuesday the 28th has 6ft of WNW swell with a 9-second period and strong energy (416), but the wind is onshore. Wednesday the 29th morning is the pick: 4ft of WNW swell, a 10-second period, energy at 257, and a light, gentle cross-onshore breeze. It’s the cleanest it’s going to be, but it’s still not great. The 29th afternoon drops to 3ft with a 10-second period and a gentle cross-shore wind. A longboard might have a fun little session.
It all fades out after that. The 30th and 31st of July, and the 1st of August, are back to 2ft to 3ft with moderate energy. The 31st of July morning and the 1st of August have clean, offshore winds, but the swell is just too small to care about.
The final days, the 2nd and 3rd of August, look like more of the same small, weak, onshore junk.
So, the only real highlight in this whole 16-day window is the Wednesday 29th of July morning. A 4ft WNW swell, a 10-second period, and the lightest wind of the whole period. It’s not a standout, it’s just the least ugly duckling in the pond. The water is a normal 18° for this time of year, so at least you won’t be shivering while you’re waiting for a wave that never comes.
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.

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.
