The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a long 16-day window ahead, and I’ll be honest with you – it’s a tough stretch. The first real chance for a surf doesn’t show up until the morning of Saturday the 22nd of August, and even then it’s a very minor affair. Before that, from Friday the 14th right through to Friday the 21st, it’s basically a write-off. We’re looking at a solid week of poor surf conditions with small, weak swell and cross-onshore winds making a mess of things. The wave energy is low, mostly in the double digits, so it’s a real grind.
Now, the one spot on the cards is Le Petit Train. It’s an exposed beach break that needs a west swell to work, and it’s inconsistent, so you have to pick your moments. The water is sitting at a very warm 78° with an anomaly of 7°, which is much warmer than normal for this time of year – a proper tropical bath.
The first glimmer of hope comes on Saturday the 22nd of August. The morning has a clean, glassy feel with a light cross-offshore breeze from the east-northeast. The swell is tiny though, only 2ft from the northwest with a short, weak period of 5 seconds. The combined energy is a low 45, so it’s barely moving. The conditions are clean, but the waves will be very small and weak. Crowds are possible here, so expect a few others out for the same scraps.
The real standout, the only true highlight in this whole forecast, is a promising window that arrives nearly two weeks out. On Thursday the 27th of August, things look much better. The morning is glassy with a light breeze from the south-southeast, and the swell jumps to a solid 5ft from the west with a period of 9 seconds, giving a combined energy of 339 – that’s moderate, punchy energy. The conditions are expected to be good. The afternoon stays clean with an offshore breeze from the east-southeast, holding 5ft of west-northwest swell. This is the best on offer by a long shot. It’s still a week and a half away, so take it with a pinch of salt, but it’s the one to circle on the calendar.
After that, the forecast takes a nasty turn. Friday the 28th of August brings a much bigger, stronger swell from the west-northwest, pushing 6ft to 7ft with a period of 10-11 seconds. The combined energy rockets up to 712 and 942, but it’s blown out by near-gale force cross-onshore winds. That’s a messy, dangerous situation, not for paddling. Same story on Saturday the 29th of August with an 8ft swell and a 13-second period, giving a massive 2318 combined energy, but again, it’s a lumpy, cross-onshore mess. For a beach break setup like this, that combination of big swell and strong wind is more interesting for the kite crew than for us.
So, bottom line: the 22nd is a tiny, clean window for the desperate, and the 27th of August is the standout. The rest is a long wait. Stay patient.
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.
