The Lowdown
Alright folks, Rusty here. Let’s talk about what we’ve got coming up at Le Petit Train. The next 16 days are a mixed bag with plenty of ordinary conditions to sit out, but there are a couple of windows where it all comes together.
The water’s *much warmer than normal* for this time of year, sittin’ at 73°, which is a solid 5° above average – you can definitely feel that pleasant difference.
We kick off Friday, September 11th, with tiny surf – only 2 ft of weak, short-period NW swell. The morning is glassy, but it’s just not enough to get excited about. That morning, however, is clean with light wind, so if you’re a total beginner it might be okay for a splash. By afternoon the wind swings cross-on and the swell bumps up to a weak 3 ft but it’s choppy and ordinary.
Saturday the 12th ain’t much better. Morning glass and 2 ft, weak and ordinary. Afternoon gets trashed by a 19 mph cross-on wind. Nothing to paddle for.
Then Sunday the 13th morning is the first real standout. Glassy conditions, clean, and we get a pulse of 4 ft WNW swell with a 12-second period – that’s proper groundswell energy. Combined wave energy cranks up to a moderate 355. It’s not huge, but for this spot, with glassy winds and that longer period, it’ll be clean and fun. You’ll want to get out early because the afternoon goes cross-on and choppy. This is the pick of the first week.
Monday the 14th morning holds clean with a 3 ft swell and offshore-ish breeze. It’s rideable and tidy but nothing special. Tuesday the 15th through Wednesday the 16th is all cross-on wind and lumpy, ugly conditions. Not worth it.
We get a little more energy on Thursday the 17th morning with 4 ft and a long 11-second period – combined energy hits 412 – but the wind is cross-shore with some chop. It’s marginal at best.
Friday the 18th morning is dead calm, glassy, but only 3 ft of weak stuff. Ordinary.
Now here’s the real standout of the whole outlook: Saturday, September 19th morning. Offshore wind from the east at 9 mph, clean, with 4 ft of WNW swell and a solid 13-second period. Combined energy is a healthy 497 – that’s moderate-to-strong energy for this break. It’s gonna be clean, lined-up, and really fun. Get on it. The afternoon will get cross-on and messy again, so make it a morning mission.
Sunday the 20th morning has offshore wind and clean 3 ft surf – again, clean but small. Monday the 21st morning is offshore again with 3 ft. Consistent clean windows if you’re after small-wave fun.
Tuesday the 22nd gets trashed by heavy onshore winds and rain/thunderstorms. Stay home.
Thursday the 24th morning is clean and cross-off with 4 ft of 12-second groundswell – combined energy 374 – actually a decent little session.
And then the final standout: Friday, September 25th morning. This one’s a beauty. Northeast light breeze, clean, with 4 ft of WNW swell and combined energy hitting a strong 568. Glassy clean conditions and solid energy. That will be the best session of the whole run if you can wait that long. By the afternoon the swell jumps to 6 ft with a very long 14-second period – that’s big, powerful groundswell, but the wind swings cross-on and makes it messy. That afternoon might be too much for beginners (over 5 ft) and the wind spoils it. For experts, the morning is gold.
Saturday the 26th morning is cross-shore and marginal with 4 ft – not the same magic.
Overall: don’t bother with most afternoons. Hit Sunday 13th morning, Saturday 19th morning, and definitely Friday 25th morning for the best waves.
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.
