The Lowdown
G’day, it’s Rusty. Let’s cut to the chase: the next couple of weeks are a bit of a write-off. There’s no real swell to speak of, the winds are mostly onshore or cross, and we’re looking at ankle to knee-high dribble for the most part. You’ll be chasing clean windows but they’re few and far between.
The water’s feeling warm, though. At Les Conches, the water temp is 71°F, which is about 4°F warmer than normal for the season. So you can maybe get away with a springsuit, but the waves aren’t doing us any favors.
We kick off on Wednesday the 9th. Morning is clear with a NNW breeze at 9 mph, but it’s cross-shore with a bit of chop. There’s 3ft of west swell with a 9-second period, but the energy is weak and it’s messy. The afternoon is worse with a 19 mph WNW wind making it lumpy and cross-onshore. Skip it.
Thursday the 10th, the swell drops to 2ft. The morning is glassy with a light breeze, which is nice, but the waves are tiny. It’s surfable but nothing to write home about. The afternoon is blown out again.
Friday the 11th, the morning is calm with a 1ft west swell, but it’s got a longer 11-second period. It’s clean, but there’s just no power. The afternoon gets a bit of push with 2ft, but it’s choppy.
Saturday the 12th is more of the same: small, clean-ish in the morning, then chopped out in the afternoon.
Sunday the 13th afternoon shows a little bump. The swell picks up to 3ft with a 12-second period, and the energy is moderate. But the wind turns cross-onshore and it gets lumpy. The morning is glassy but the waves are only 1ft.
Monday the 14th morning is the pick of a bad bunch. 2ft of west swell, 10-second period, and a light cross-offshore wind making it clean. It’s surfable but still very small. After that, it’s mostly tiny and onshore for a few days.
There’s a gap with nothing worthwhile from Tuesday the 15th through Wednesday the 16th. Thursday the 17th morning shows a glimmer: 2ft of west swell with a gentle offshore breeze. It’s clean, but the energy is low. It’s a maybe.
The following week is even weaker. Small, crossed-up, and mostly poor. There’s a clean but tiny window on Monday the 21st with a light offshore breeze, but that’s about it.
Honestly, there are no standouts in the entire run. The best you’ll get is a clean, knee-high day. The few times we see any real size, the wind blows it out. For most of this, it looks more like a kite-surfing forecast than a surfing one.
Keep your expectations low and your eyes on the horizon. Forecasts can change, but as it stands, it’s a flat spell.
Rusty.

Information about the Les Conches Surf forecast
The above surf forecast table for Les Conches provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Les Conches can be found by selecting the local surf guide option on the grey menu. Our Les Conches 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 (Les Conches) 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 Les Conches 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.
