The Lowdown
Alright, Rusty here. Let’s take a look at what’s cooking at Le Petit Train.
Starting off, we’ve got a few sessions worth checking out, but the one that really stands out is Thursday morning, 10 September. That morning you’re looking at a 7ft WNW swell with glassy conditions and no wind – total calm, super clean. The combined swell energy is a strong 521, so there’s a lot of power, but the period’s only 8 seconds, so it’s a shorter-period wind swell that’ll hit hard and fast. This one’s definitely for the experienced crew, as it’s over 5ft.
Water temp is 75°F, which is about 5° warmer than average – that’s really warm for this time of year, so a spring suit or even trunks will do you fine.
Before that, Tuesday morning, 1 September, offers a clean 4ft WNW swell with a light NE cross-offshore breeze and moderate combined energy of 307. It’s good, clean, and surfable – a solid choice for an early paddle.
Then Saturday morning, 5 September, has a glassy 3ft WNW groundswell (12-second period) with combined energy of 219. That long period will give you some nice lines, but it might close out a bit on the beach. Still, clean and small, good for a longboard.
Further out, Tuesday morning, 15 September, shows a clean 4ft WNW groundswell with a light ESE offshore wind and combined energy of 451. This one’s more of a promising long-range call, so keep it on your radar but don’t set your watch by it yet.
In between those, there are long stretches of poor or ordinary conditions, especially in the afternoons when the wind turns onshore and messes things up. The surf won’t ever be flat, but it’ll be lumpy and messy.
Le Petit Train is an inconsistent break, so when it fires like on the 10th, you want to be there. Crowds can happen sometimes, especially on a day that clean.
Beginners, aim for the smaller, clean days like Tuesday 1st or Saturday 5th – those are your safest bets. That 10th is for the rippers.
So, the real winner is Thursday the 10th, with a possible backup on Tuesday the 15th. The rest? You’ll be waiting and watching for the good ones.
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.
