The Lowdown
Alright, let's talk about what we're working with here. The story is pretty simple, and it ain't good. We're focused on Le Petit Train, and for the whole 16-day stretch, there's no surf worth getting wet for. The forecast is a long string of poor days, with one morning that's just barely ordinary.
The water's sitting at 78°F, which is a massive 7°F warmer than it should be for this time of year—that's very unusual.
The first week is a total loss. Tuesday the 18th kicks off with a tiny 2ft NW windswell and a period of just 5 seconds, blown onshore by a 9 mph NW wind. That weak energy reading of (30) says it all. Wednesday the 19th drops to 1ft, and Thursday the 20th bumps up to 3ft with an 11-second period, but it's cross-shore and the combined energy is only (191). Still poor.
There's one brief window on Saturday morning the 22nd where we get a light SE offshore wind at 9 mph and a clean 3ft swell (WNW, 9 sec, 151 energy), and the notes say "surfable waves but very ordinary conditions". That's it. That's the best of the whole period, and it barely scores. The rest of the first week is onshore junk or tiny chop.
Into the second week, a pulse of swell arrives on Thursday the 27th of August with 7ft (WNW, 10 sec, 763 energy) and 6ft that afternoon. That's a strong energy level, but the wind is cross-onshore from the SW and WSW—that's choppy, messy surf. For a beginner spot like Le Petit Train, that's blown-out and no fun. Friday the 28th sees 3ft with a clean cross-shore from the SSW, but it's still scored as poor. Saturday the 29th through to September 2nd is a mix of onshore wind, strong breezes, and near gale-force wind by Monday the 31st. It's a full-on blowout.
There are no standouts. The only "not poor" moment was that Saturday morning the 22nd, and even that was just ordinary. For a spot that's exposed to the west and inconsistent, this is a blank run. With such consistently poor conditions, some of those bigger 6ft days with strong cross-onshore wind could look better for kite-surfing than paddle surfing, but we're not making that call. The outlook doesn't improve.
Keep the board in the car and wait for a better forecast.

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.
