The Lowdown
Alright team, Rusty here again, talking about Le Petit Train. The water’s unusually warm at 73°, running way hotter than normal for this time of year.
We’ve got a bunch of days where the wind is gonna mess with the waves. The swell is coming from the west-northwest, but so are the winds a lot of the time, making things cross-onshore and choppy. There’s a long patch of poor conditions from Saturday afternoon through Thursday, but we’ve got some sweet windows to work with.
First real session is Sunday the 13th in the morning – glassy, dead calm with a light northeast breeze at 3 mph. Waves around 4 ft from the WNW with a solid 13-second period. That’s a proper groundswell with combined energy at 361 (moderate). It’s clean and small, but fun. It’s inconsistent here though, so be patient. Crowds are possible.
Monday the 14th morning is another clean one – light east cross-off at 3 mph. The swell is about 3 ft at 11 seconds, energy at 221 (moderate). A good session before the afternoon chop sets in.
The real standout for the first week is Saturday the 19th morning – light south cross-off at 6 mph, 5 ft swell from the WNW at 13 seconds. The energy jumps to 669 (strong). Clean and solid.
Then Monday the 21st morning – light east-northeast cross-off at 3 mph, 4 ft at 13 seconds. Energy is 595 (strong). Clean again.
Now, mark this one down: Tuesday the 22nd morning. Glassy conditions with a 3 mph east-northeast breeze. Swell hits 6 ft from the WNW at 13 seconds. The energy is a massive 1077 (very strong). This is for experienced surfers only – over 5 ft and punchy. Best of the whole outlook.
Later in the month it fades off. One to skip: Sunday the 27th has 25 mph north-northwest cross-on winds, light rain, and a 3 ft swell – more of a kite day.
So, hit Sunday the 13th morning, Saturday the 19th morning, Monday the 21st morning, and for the big one, Tuesday the 22nd morning.
Catch you in the water,
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.
