The Lowdown
Alright folks, Rusty here. Let’s have a look at what Le Petit Train has in store for us over the next couple of weeks.
The long-range picture is a bit of a flat spell for the most part. The first ten days or so are looking like a write-off for any decent waves. There’s a real gap in quality surf from now until around the very end of the month. We’re seeing a lot of small, weak, onshore, or just plain messy conditions.
From Tuesday the 18th through to the weekend, it’s all small swell with wind blowing from the wrong directions. Tuesday the 18th has a tiny 2ft from the NW with onshore wind, and it doesn’t get much better. Wednesday the 19th has a weak 2ft with a cross-onshore breeze. The energy is pitiful, barely registering above 30 on the energy scale. Thursday the 20th does see a bump to a 3ft swell from the WNW with an 11-second period, giving us a moderate combined energy of 238, but the cross-on wind and cloudy skies keep it from being any good.
We get a brief glimmer on Saturday morning the 22nd with a 3ft WNW swell and a clean cross-offshore wind from the ENE, but it’s very ordinary. That’s about as good as it gets for a while. The next week, from the 23rd to the 30th, is a real grind. Tiny waves, onshore wind, and very low energy, mostly in the double digits. Not worth paddling out for.
Now, there is a bit of light at the end of the tunnel, but it’s a long way off. On Saturday the 31st of August, the morning looks promising. We’ve got a 4ft swell from the NW, clean conditions with an offshore wind from the SE, and the combined energy is a solid 237. This is our first true standout. Then on the 1st of September, we get two windows. Tuesday morning has a 3ft WNW swell with a clean cross-offshore breeze, and the energy is at 239. But the real gem is Tuesday afternoon: a 4ft NW swell, glassy conditions with a light south-west wind, and energy at 239. That’s as clean as it gets, folks. The only caveat is that this is over a week away, so it’s promising but we’ll need to keep an eye on it.
Le Petit Train is an exposed spot that likes swell from the W, but these swells are coming from the NW or WNW. It’s also inconsistent, so when it does show up, don’t expect a constant line-up. The water temp is about average for this time of year, nothing to write home about.
Given the long run of small, windy, and messy conditions, a lot of this period is going to be a washout. But that clean window at the very end is what we’re aiming for. Keep your fingers crossed.
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.
