The Lowdown
Alright, folks, Rusty here. Let’s break down the next 16 days for Trestraou. It’s a rough patch overall. The water is a touch warmer than usual for this time of year, sitting at about 66°F, so that’s a small win.
The Big Picture
Most of this window is a dud. The wind is all wrong, and the surf quality is poor. The first real chance of a decent wave doesn’t appear until the 4th of August. Expect a lot of flat, choppy days before that.
The First Week (Now through early August)
Sunday the 26th of July kicks off with a 7 ft swell from the WNW, but a 30 km/h cross-shore wind turns it into a lumpy mess. The energy is moderate at 475, but it’s not worth suiting up. Monday the 27th and Tuesday the 28th are smaller, dropping to 5 ft and 3 ft, with the same cross-shore chop. Wednesday the 29th morning is clean with a light cross-offshore wind, but the swell is only 2 ft and the energy is weak (67). Nothing to ride.
Thursday the 30th and Friday the 31st stay small – 3 ft to 4 ft – with cross-shore winds. The weekend (1st and 2nd of August) is dead with onshore winds and tiny, weak swell.
The One to Watch
Tuesday the 4th of August is your window. The morning has a 4 ft West swell, a 25 km/h cross-offshore wind, and moderate energy at 313 – it’s clean. The afternoon is better: 5 ft from the West, 30 km/h cross-offshore, and energy at 424. The period is 10 seconds, which is decent for a groundswell. This is the only real standout – clean, surfable, and solid.
The Second Week (5th to 10th of August)
Wednesday the 5th of August is “surfable but ordinary.” The morning has 5 ft and a cross-offshore wind, but the energy drops to 297. The afternoon gets messy.
Then it gets big. Thursday the 6th of August morning has a 10 ft WNW swell with a 10-second period and massive energy at 1406. The wind is light cross-onshore, so it’s choppy. That’s expert-only territory. Saturday the 8th of August is similar: 10 ft from the West, energy at 1849 in the morning and 1718 in the afternoon, with cross-shore winds. Powerful, bumpy, and only for the brave.
The run fades from the 9th of August. Sunday the 9th has 4 ft to 3 ft from the West with cross-offshore winds – clean but small. Monday the 10th of August has a 35 km/h offshore wind, but the swell is only 3 ft and weak (110). Clean, but no power.
Bottom Line
Circle Tuesday the 4th of August. The 5 ft West swell with a clean cross-offshore wind is your best chance. The 6th and 8th of August have size for experts, but expect rough conditions. The rest is a waiting game.
Rusty.

A general guide to surfing at Trestraou can be found by selecting the local surf guide option on the grey menu.

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.
