The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Seignosse - Les Bourdaines over the next couple of weeks.
Honestly, the first week is a real struggle. We’ve got tiny, weak swell and a lot of messy wind. For the first few days we’re looking at waves in the 2ft to 3ft range, but with periods around 6 seconds, there’s just no power in the water. The combined energy is weak, mostly under 100 (60-90). Mornings are glassy or clean, but the swell is too small to get excited about. The water is a notable 76°F, which is much warmer than normal for this time of year, so that’s a bonus if you’re just floating about.
The real story is the big swell that arrives on the 25th of July. Saturday afternoon sees the swell jump to 6ft from the WNW, with a period of 7 seconds, and the combined energy hits 266 (moderate). This is a serious shift. Sunday the 26th of July is the standout, with the swell peaking at 7ft to 10ft from the WNW, period hitting 8 seconds, and energy readings soaring to 374 and then 975 (strong). That is a lot of water moving around. However, and it’s a big however, the wind is onshore and strong – 12 to 19 mph from the W and WNW. The surf conditions are consistently described as poor. For a beach/jetty setup like this, with that much onshore wind, this is going to be a washed-out, choppy mess. It’s honestly more interesting for kite surfing than paddle surfing at that point. This swell is also too big for beginners, and the 10ft stuff is expert-only territory.
The swell drops back down through the 27th and 28th of July, with 4ft to 6ft from the NW, but still with cross-onshore winds, so it remains poor. The glassy mornings on the 29th and 30th of July offer a small window of hope with 3ft waves from the NW and a longer period of 9 seconds, giving a bit more shape. The combined energy is still just moderate (126-137), but it’s clean. That’s your best bet for a manageable, clean wave in the second week.
Heading into the beginning of August, we’re back to small, weak swell. The 1st of August morning has a glassy 3ft from the WNW, and the 2nd of August morning has a clean 3ft from the NW with offshore ENE wind, but the energy is very low. It’s just ordinary.
So, the best on offer? The glassy morning of the 29th of July. It’s only 3ft from the NW, but with a 9-second period and glassy conditions, it’ll be clean and fun on a longboard. The other contender is the same type of setup on the morning of the 30th of July. The big swell on the 26th of July has the size and power, but the wind ruins it for a paddle surfer.
Stay safe, keep your eyes on the horizon, and don’t force a bad session.
Rusty.
