The Lowdown
Alright folks, Rusty here. Let’s be straight with you right off the bat. Looking at the next 16 days at Trestraou, it’s a tough sit. The forecast is a long, dry stretch of poor surf conditions. There isn’t a single standout session in the whole window, so we’re talking about a full blank run from Wednesday the 15th of July all the way through to Thursday the 30th.
The first few days are a write-off. Wednesday the 15th sees a tiny 3ft swell from the NE with a short period of 5 seconds, blasted by a 12 mph cross-on breeze. The water is 64°, which is a touch warmer than normal for this time of year. The wave energy is weak (75), and it’s just choppy and messy. Thursday and Friday are more of the same – small, weak swells with onshore winds.
We get a slight bump in size on Sunday the 19th, with the swell hitting 5ft, but the wind is howling from the ENE at 25 mph, and the combined energy is moderate (145). The result is a strong, messy cross-onshore wind that will ruin any chance of a decent wave. It’s a no-go.
The same pattern holds through the next week. Swell sizes pop up to 5ft and 6ft around the 22nd and 23rd, but the wind is always onshore or cross-on, keeping the surface lumpy and choppy. The energy peaks at 222 on the afternoon of the 22nd, which is moderate, but with that wind direction, it’s just not surfable.
The only change comes right at the end of the month. Starting Sunday the 26th of July, the wind finally swings offshore (cross-off) from the west, cleaning things up. But the swell is tiny – 2ft on the Sunday, dropping to 0.7ft by the 30th. The wave energy is weak (54 on the 26th), and the period is short. It’s clean, but there’s no power.
So, the bottom line for Trestraou: there are zero good waves on offer in this 16-day outlook. It’s a classic summer flat spell or a run of bad wind. Stick to the pool or take up golf. The forecasts can always change, but for now, it’s a total blank.
Rusty.
