The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a single spot in the mix for the next 16 days: Le Petit Train. It’s not a flashy setup—beginner-friendly, inconsistent, and exposed to the west. The water is a balmy 77°F, which is a whopping 6°F warmer than usual for this time of year, so it’s very unusual. You’ll be surfing in a bath.
The outlook starts on Friday, 21st August, but it’s a write-off. Winds are onshore from the WNW at 12 mph with 5 ft of lumpy swell and poor surf conditions. The combined wave energy is moderate at 394. Not worth a paddle.
Saturday, 22nd August, things look a little better for the morning. The wind swings east at 9 mph, blowing offshore, and the swell drops to 3 ft from the WNW with a 9-second period. The wave energy is moderate (151), and it’s clean. The surf is ordinary but at least it’s surfable. The afternoon turns cross-onshore and choppy, so get it early.
Sunday, 23rd August, is a dud. The swell drops to 2 ft in the morning and 1.0 ft in the afternoon. Very weak energy (34 and 15). The wind is messy, and the waves are poor. Skip it.
Monday, 24th August, stays tiny. 1.0 ft from the west with light winds. The energy is pathetic (19 and 17). Not worth a look.
Tuesday, 25th August, is a mess. The morning has 3 ft of 4-second windswell from the SW with 16 mph cross-onshore winds. The energy is weak (30). The afternoon has a 0.7 ft, 12-second groundswell, but the period is long and the wind is cross-onshore. Poor conditions all day.
Wednesday, 26th August, offers a clean morning. ESE wind at 9 mph offshore, 2 ft from the west with a 7-second period. The energy is weak (62), but it’s surfable and clean. The afternoon dies with light wind and 2 ft.
Thursday, 27th August, the swell picks up but the wind ruins it. 5 ft in the morning with 19 mph cross-onshore winds (moderate energy, 270), and 8 ft in the afternoon with 22 mph cross-onshore (strong energy, 681). That’s too big for beginners and only for experts, but with that wind, it’s a washing machine. More interesting for kite surfing than paddle surfing.
Friday, 28th August, holds 6 ft of WNW swell, but the wind is cross-onshore and lumpy at 19 mph. Energy is strong (398 and 396). Poor conditions.
Saturday, 29th August, the swell is 6 ft in the morning and 5 ft in the afternoon, both from the WNW with 9-second periods. The energy is strong (541 and 404). The wind is onshore, so the surf is messy and marginal. Not a standout.
Sunday, 30th August, morning is the best we’ve seen. The wind is light from the SSE at 3 mph, blowing cross-offshore, and the swell is 5 ft from the WNW with an 8-second period. The energy is moderate (293), and it’s clean. The wave comment says “expect good surf conditions.” This is the top pick for the whole window. The afternoon turns onshore again, so don’t sleep in.
Monday, 31st August, the morning has 4 ft from the WNW with a 9-second period and light SSW wind at 3 mph, cross-shore. The energy is moderate (237). It’s marginal, but clean enough for a quiet session. The afternoon goes onshore and poor.
From Tuesday, 1st September, through to Saturday, 5th September, it’s a long stretch of poor to marginal conditions. The swell stays small to moderate, but the wind is consistently onshore or cross-onshore, often strong (19 to 25 mph). There’s one notable bump on Thursday, 3rd September, with 7 ft to 8 ft of west swell and strong energy (732 and 744), but the wind is fresh cross-onshore. That’s expert-only, messy, and likely a kite day.
So, the standout is Sunday, 30th August, in the morning. Clean conditions, 5 ft of WNW swell, and light offshore wind. The rest of the window is a struggle. The inconsistency of Le Petit Train means it’s not a shock to see long gaps of poor surf. Still, that Sunday morning is worth calling in sick for.
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.
