The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Le Petit Train.
Honestly, the next couple of weeks are mostly a slow grind, but there are a couple of windows to watch. The water’s sitting at about 73°F, which is roughly 4°F warmer than usual – that’s a real treat for this time of year.
First chance to paddle out is Thursday morning (September 10th). It’s a 3ft swell from the WNW with a 10-second period. The energy is moderate (186), and the wind is a light cross-offshore from the SE, so it’ll be clean. It’s surfable, but nothing special. The swell direction isn't quite matching the ideal W swell direction for this spot. By afternoon, the wind picks up from the NW at 12 mph, blowing cross-on and chopping it up.
The rest of the first week is a bust. Friday (11th) is small and messy. Saturday morning (12th) is glassy, but the swell is only 3ft with weak energy (78) – not enough to get excited about.
Sunday morning (13th) brings a slight bump: a 4ft groundswell with a very long 13-second period. The energy jumps to 361, so it’ll have some punch, but the wind is light and cross, so the surface won’t be perfect. It’s marginal.
Monday morning (14th) is the best of the first week. A 3ft swell from the WNW, a 10-second period, and dead glassy conditions. The energy is moderate (210). The waves will be clean and rideable. Expect it to be inconsistent – that’s just how this spot is – but if you want a quiet session, this is your window.
Then we hit a long, boring stretch. From Monday afternoon all the way through to the end of the third week of September, it’s onshore winds, chop, and tiny surf. Not worth your time.
Now, looking way out to Friday morning (September 25th), that’s the one to keep in the back of your mind. It’s a long way off, so take it with a pinch of salt, but the forecast is juicy: a solid 7ft swell from the WNW with a very long 14-second period. The energy is strong (1800) – that’s a powerful groundswell. The wind is a clean offshore breeze from the east at 9 mph, which will set it up perfectly. This is real, clean, powerful surf. But at over 6ft, it’s for experienced riders only. The long period means it’ll be a bit fat and straight-breaking at this beach, so look for the longer walls. The afternoon gets messy, so the morning is the session.
Bottom line: the first week has one decent glassy morning on the 14th, but the real standout is the big groundswell on the 25th. It’s a long shot, but it could be the one to make the wait worthwhile.
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.
