The Lowdown
Alright, folks, Rusty here. Let's be straight with you. I've looked at the charts for our stretch of coast, and it’s a tale of two weeks. The first part of this outlook is a frustrating wait, but there’s a light at the end of the tunnel.
The start of the period is a write-off for any of us looking to get a proper wave. From now through the 19th, we're looking at weak, short-period surf with onshore winds messing up what little is there. The swell energy is just pathetic, with readings mostly in the 20s and 30s. It’s not even worth paddling out for. You’ll see the water temp is sitting at 76°F, which is much warmer than normal for this time of year, but that's about the only positive.
We finally see a pulse of energy arrive on the morning of Thursday the 20th. A 2ft NW groundswell with an 11-second period shows up, and the energy jumps to 131. It's clean with light offshore winds, but honestly, it's still pretty ordinary. Thursday afternoon, the wind swings cross-shore and bumps it up a bit. It's surfable but nothing to get excited about.
Now, hold onto your boards, because Friday morning, the 21st, is where things get interesting. That NW groundswell builds to a solid 5ft with that same 11-second period, and the energy jumps way up to 472. The wind is glassy offshore, and the conditions are looking clean. This is the standout of the first week. Hossegor – La Graviere is an exposed sandbar, and it’s fairly consistent. This is the one you want to be awake for. Get on it. The afternoon, however, the wind goes cross and chops it up, so it’s a morning mission.
The weekend stays mediocre. Saturday the 22nd has some small, glassy waves in the morning around 4ft, but it’s nothing special. Same with the start of the next week. We’re in a bit of a lull from the 23rd to the 25th, with small, weak swell and onshore winds making a mess of things. It’s a few days of frustration, no doubt.
But then, looking ahead to the end of the period, there’s promise. The big one is on the morning of Wednesday the 26th. We've got a 2ft NW long-period groundswell with a 12-second period. The wave height is small, I know, but that period means real energy. The combined energy reading is 236, and it’s mostly clean with an offshore breeze. This is a long-period swell, which at a beach break like La Graviere can sometimes break a bit straight, but it should have some power behind it. It’s worth checking out.
The last day with any real potential is the morning of Thursday the 27th. A 4ft NW swell with an 11-second period brings the energy up to 292, but it's got a cross-onshore wind and is described as marginal. It could be a bit of a battle.
And that’s about it. The rest of the month just fades away into small, weak, and messy surf. So, if you’re keen, your best bets are the mornings of Friday the 21st and Wednesday the 26th. The Friday swell has more size, but the Wednesday swell has that long-period quality. Both have light offshore winds. Mark your calendars.
Stay salty.
