The Lowdown
Alright, Rusty here. Let's take a look at what's on the table for the next couple of weeks.
Honestly, I gotta be straight with you – it's a grim run for a while. The only break that's even showing up is Le Petit Train, and for a long stretch, it's just not working. We're looking at a solid string of days with poor surf conditions and not much to get excited about. The water is a toasty 78°, which is *much warmer than normal* for this time of year – feels like a bath out there, but with a lot of frustration.
Let's walk through it. The first real chance we see anything is on Saturday morning, the 22nd of August. The swell is a tiny 3 ft from the WNW with a period of 9 seconds, so not a lot of push. The ENE wind is cross-offshore, which will keep it clean, but the combined energy is only 151 (weak to moderate). It's surfable, but "very ordinary" is the name of the game. Not worth a special trip.
Then we hit a real dead zone. From Sunday the 23rd right through to Wednesday the 26th, it's mostly tiny, weak, or messy. We're talking ankle-biters with a lot of onshore wind. The swell drops to 1.0 ft and 1 ft, and the energy numbers are barely double digits. There's just nothing doing.
The only flicker of something bigger comes on Thursday the 27th of August. The swell jumps up to 8 ft from the west, with a 9-second period. The combined energy hits 1033 (strong), but here's the catch – the wind is a SW cross-shore and there's a risk of thunderstorms. The forecast says "marginal" and the score is low. With that size, it's getting into the "experts only" zone, and the wind is going to make it a lumpy mess. By the afternoon, the wind is a howling 28 mph onshore, and the swell is 10 ft – that's not surf, that's survival. Honestly, for a beach setup like Le Petit Train, this looks more interesting for the kite surfers than anyone with a paddle.
That big wind hangs around for a few days, with 25 mph onshore winds and 7 ft+ swell. The energy is high (768-664), but the quality is zero. The wind just kills it.
We finally get a little window of calm on Friday the 4th of September. The morning shows a 5 ft swell from the WNW with an 8-second period, and a light ENE wind that's cross-offshore. The energy is 322 (moderate). The conditions are expected to be good, and the wind is light, so it'll be clean. The light wind is a major positive. This is the only standout in the whole 16-day window. It's a long way off, so treat it as a promising idea, not a guarantee. For the afternoon, it drops to 5 ft and the wind swings north, making it a bit more glassy but the period improves to 9 seconds. Still worth a look.
So, for the next two weeks, your best bet is to mark that Friday morning, September 4th, on your calendar. Before that, it's a whole lot of waiting for a whole lot of nothing.
Rusty.

Information about the Le Petit Train Surf forecast
The above surf forecast table for Le Petit Train provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Le Petit Train can be found by selecting the local surf guide option on the grey menu. Our Le Petit Train surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Le Petit Train) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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 Le Petit Train 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.
Le Petit Train is 8 km (5 miles) from Arcachon. If you plan a holiday in Gironde, look for hotels and other accommodation in Arcachon. Arcachon has rooms for a wide range of budgets as well as car hire and transport links.
