The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for our stretch of coast. It’s a bit of a mixed bag, but there’s a window of clean fun if you pick your moments.
Right off the bat, the first few days look pretty grim for a proper paddle. Tuesday afternoon the 15th has a tiny 2ft swell from the WNW and a sloppy 12 mph onshore wind. The water is warm, a standout 74°, which is much warmer than normal for this time of year, so that’s a nice touch if you’re just floating, but the surf is poor.
Wednesday and Thursday keep that same story: lumpy, messy conditions with WNW swell hovering around the 4ft to 5ft mark, but winds are cross-onshore or onshore, chopping it all up. The combined wave energy is moderate for that period, hitting up to 460, but it’s wasted with the wind.
Friday the 18th is more of the same – poor conditions – though there’s a window of cleaner, cross-shore wind on the Friday morning that might offer a tiny sliver of hope, but the swell is weak and short period at 9 seconds. Not worth getting excited about.
Now here’s where things get interesting. Saturday morning, September 19th, is the true standout of the entire outlook. This is the session you want to be in the water for. A beautiful 5ft WNW groundswell, with a proper 13-second period, is rolling in. The combined energy is strong at 669, and the wind is a light, clean 3 mph south-southwest cross-offshore. That’s glassy. Le Petit Train will be clean, lined up, and offering some proper waves. This is the best on offer, no contest. Just know that it’s an inconsistent break and crowds are possible, so get there early.
Sunday morning the 20th is a close second, with a lighter 4ft swell but still clean with light cross-off winds (3 mph from the NE). A good option if you missed Saturday, or want a more relaxed paddle.
After that, the pattern goes back to choppy afternoons with strong cross-on winds. Monday and Tuesday mornings (21st and 22nd) are clean, but the swell is smaller, around 4ft to 3ft, with moderate wave energy (250 and 211). Worth a dawn patrol if the Saturday swell has you hooked.
The next week is more of a long-range tease. Wednesday the 23rd sees a pulse of 4ft, 14-second groundswell with strong energy (724), and the morning is clean. It’s flagged as marginal – probably tide dependent – but it could be worth a look. Thursday and Friday mornings (24th and 25th) are clean but the swell drops off (4ft down to 3ft, moderate energy). Saturday the 26th is small and poor.
There’s a gap here until Sunday morning, September 27th, which looks promising again: a clean 4ft, 13-second groundswell with light cross-off winds and a solid 499 combined energy. That’s a quality long-range call.
The very end of the outlook, Monday the 28th and Tuesday the 29th, is messy with bigger, wind-affected swell (5ft to 6ft, choppy). The only real clean option at the tail end is Wednesday morning, September 30th, with a clean 5ft, 10-second swell. It’s not the standout period, but a solid backup for the dedicated crew.
Bottom line: Saturday the 19th is your best bet. Sunday morning the 20th is the backup. The rest is a waiting game for those clean windows.
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.
