The Lowdown
Alright, this is Rusty, and I'm looking at the next couple of weeks for our little corner of the coast, specifically Le Petit Train.
Right off the bat, the water is running a remarkable 77°F, with a temperature anomaly of 7°F, meaning it's much warmer than usual for this time of year. That’s a real treat.
Things start a bit slow, and we have a gap with no worthwhile surf. The first real shot at something decent comes after a few days, on Tuesday, 1st September. That morning we’ve got clean 4ft swell from the WNW, a light offshore breeze, and the combined energy is moderate at 301. It’s nothing huge, but for a beginner-friendly spot like this, that’s a nice, manageable window. The crowds can turn up here sometimes, so get in early.
The rest of the first week is pretty ordinary. There are a few clean mornings with light or offshore winds, but the swell is small and weak, with combined energy dropping below 100 on Wednesday, 2nd September. The energy picks up again for the Saturday 5th September, with a 5ft WNW swell and a long 13-second period (799 energy), but the onshore wind ruins it that afternoon. The period is long enough that the waves might be a little too straight for this beach break, anyway.
Looking further out, there's a promising run starting on Saturday, 12th September. The Saturday morning has a glassy 5ft WNW swell (426 energy) – that’s a top pick for a calm, easy session. But the real standout window hits on Sunday, 13th September. The morning brings a clean 6ft WNW swell (564 energy) with a gentle offshore breeze. That's shaping up to be the best surf of the whole outlook: solid size, clean lines, and that perfect offshore wind. It's a week and a half away, so keep your fingers crossed, but the signs are good.
The run continues into Monday, 14th September, with another clean morning: 6ft swell (692 energy) and a light offshore. The afternoon stays clean and glassy with 5ft (473 energy). This later stretch is where the magic is.
If the winds don’t cooperate on the bigger days, and the swell gets up over 8ft like on Wednesday, 9th September, the conditions look pretty lumpy and onshore – more of a kite session than a paddle session honestly.
So, for the standouts: Saturday morning, 12th September, for the glass and the clean 5ft waves, but the real one to circle is Sunday morning, 13th September. That’s where the swell, the offshore, and the energy all line up for the best ride of the forecast.
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.
