The Lowdown
Alright, Rusty here, looking at the same stretch of water. Things start off slow for Le Petit Train.
Your first real chance is the morning of Sunday the 13th. It’s going to be clean with a 3.6ft groundswell from the WNW, running on a 13-second period. The water’s sitting at 73.2°, which is much warmer than usual for this time of year – a nice surprise. The wind will be glassy out of the ENE, and the combined swell energy is a moderate 361. For an inconsistent break that’s good for beginners, that’s a solid window. But you’ve got to get it in the morning. By the afternoon, the wind swings hard to the NNW at 25 mph, turning it into a choppy mess. That same story holds for Monday and Tuesday mornings – a brief glassy window with 3.3ft to 2ft of swell before the onshores blow it out.
Then we hit a real dry spell. From Tuesday afternoon through the 18th, there’s nothing to write home about. Just a lot of poor conditions, strong onshores, and weak wave energy. It goes flat as a pancake.
Now, the second week is where the real hope is. You’re going to want to mark your calendar for Saturday the 19th. That morning is looking like the absolute highlight. We’ve got a clean 5ft swell from the WNW with a 13-second period, pumping the combined swell energy up to a strong 769. The wind is forecast to be dead calm – glassy – so it’ll be perfect. That is the session to plan for. It might be a little heavy for total beginners, but for the rest of you, it’s a no-brainer. Sunday the 20th morning also looks excellent with glassy conditions and 4.6ft of swell, but that Saturday is the one. Since this spot doesn’t break all the time, a lull like we see mid-week is pretty standard. Expect some company on those good days.

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.
