The Lowdown
Alright, let’s get into it for Seignosse - Les Bourdaines over the next couple of weeks.
Honestly, the first week and a half is a real bust. From Friday 17 July right through to Tuesday 28 July, there’s barely a ripple worth paddling for. The swell is tiny, the wind is mostly onshore, and it’s just a bummer. The water is a warm 75°F, which is much warmer than normal for this time of year, so that’s a small comfort if you’re just floating around.
Then things start to kick off around Wednesday 29 July. The wind is onshore and strong from the WNW at 19 mph, so it’s going to be messy, but the swell is building with a 12-second period and a solid 5ft. The combined energy is 747 (moderate-strong), but the wind is just too rough for a proper session.
The real standout is the end of the month. Thursday 30 July, the swell jumps to 8ft from the NW, with a 10-second period, and the combined energy is a thumping 1254 (strong). The wind is onshore WSW at 9 mph, so it’s not perfect, but that’s a lot of power. By Thursday afternoon, the swell holds at 8ft, period 11 seconds, and the energy hits 1654 (very strong). The wind is cross-onshore WNW, so it’s a bit lumpy.
But Friday 31 July – that’s the one. Early morning, the wind is dead calm, glassy, with light rain. You’ve got a 8ft NW swell, period 11 seconds, and an energy reading of 1375 (very strong). This is for experts only – that’s a big, powerful wave, and with that long period, it’s a proper groundswell. At a beach/jetty setup like Les Bourdaines, that long period might make it a bit straight, but the glassy conditions are a dream. This is the best on offer, no doubt.
The waves fade into the first of August, dropping to 5ft on Saturday morning, but the wind is back onshore, so it’s a slow finish.
So, the call: suffer through the flat spell, then get ready for a big, powerful, glassy day on Friday 31 July. It’s an expert-only day, but it’s the best we’ve seen in the forecast.
