The Lowdown
Alright, let’s get real about the surf ahead. To be honest, looking at the next 16 days, it’s a pretty flat and frustrating stretch. There are no real waves on the menu, and for the most part, we’re looking at tiny, junky lumps that aren't going to get anyone too excited. It’s the kind of forecast where you’d be better off checking the tides for a walk on the beach than paddling out. The first week is basically a write-off, with nothing but knee-high slop and onshore junk. The good news, if you can call it that, is that there’s a slight pulse of energy around the middle of the second week, but the swell direction and the wind look like they’ll keep it messy. It’s a long stretch of nothing, but that’s the way it goes sometimes.
Let’s break it down. The water temp is sitting at 69°, which is about average for this time of year, so no surprises there.
The first few days are a total bust. Wednesday the 5th has a bit of 3ft west swell, but it’s short-period and cross-onshore, making for poor, choppy conditions. The energy is weak, (89). Thursday the 6th is more of the same, with a drop in size and a morning cross-offshore wind that cleans it up a little, but it’s still only 3ft and pretty ordinary. The wind goes onshore and strengthens in the afternoon, killing it. Friday and the weekend are tiny, with waves barely reaching 1ft, and the energy is just pathetic. It’s not even worth thinking about.
We’ve got a gap of a few days here where there is absolutely nothing on offer. The swell drops right off, and it’s just small, messy leftovers. It’s a rough patch.
Looking ahead to the second week, there’s a little more life, but it’s still not good. The morning of Thursday the 14th shows a slight bump to 3ft with a glassy surface, and the energy is starting to pick up (141). It’s surfable, but ordinary. The afternoon sees size jump to 4ft, but the wind swings onshore, making it messy. The morning of Saturday the 16th and Monday the 18th see some more swell, up to 4ft and 5ft, but again, the winds aren't helping. There’s a real standout moment on the morning of Wednesday the 19th. The forecast is calling for 4ft of west swell, and the conditions are predicted to be favorable, but the caveat is that it’s predicted to be too big for the break. The energy is up there at 246, which is moderate, but the quality is the issue. It’s a maybe, but it’s not looking like a classic.
Overall, the best you can say is that there’s a tiny window on the 14th and maybe the 19th, but nothing is worth getting excited about. It’s a flat spell, and we’ll have to wait for the ocean to wake up.

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