The Lowdown
Alright crew, Rusty here. Let’s be straight – I’ve scanned this 16‑day window for the region around Les Dunes and, honestly, there’s nothing worth paddling out for. Every single session from Wednesday 15 July right through to Thursday 30 July is rated as poor surf with a score of zero. That’s a full two‑week blank run for a break that’s usually fairly consistent, so it stings.
The water temperature on that first Wednesday afternoon is sitting at 71°, which is a whopping 5° warmer than normal for this time of year – that’s unusual, almost like the ocean’s having a summer fever, but it doesn’t do a thing for the waves.
Les Dunes is a beginner spot, exposed to WSW swells, but what we’re seeing is tiny, weak, disorganised junk. Swell heights barely touch 4 ft on Friday morning (17 July) but it’s period 5 seconds – pure wind slop. Combined wave energy peaks at a measly 83 (moderate energy on paper, but with that period it’s all chop). Winds are mostly cross‑onshore or straight onshore, making a mess of even the smallest bumps. A few mornings go glassy (like Saturday 18 July morning) but the swell is only 0.7 ft – not enough to stand up on.
There’s one stretch from Sunday 19 July afternoon into Tuesday 21 July where the wind turns offshore or cross‑off, and the water goes clean, but again the swell is a pathetic 0.7 ft with energy in the single digits. You’d be floating, not surfing. Even the long‑period stuff (14 seconds on 24 July Friday afternoon) delivers just 0.3 ft – a groundswell that’s too small to feel.
By the end of the window, around 28–30 July, a slight uptick to 3 ft–3 ft shows up, but period drops to 4–5 seconds and the wind stays messy. Still poor. For a beginner break that needs some size and clean conditions, this is a write‑off.
So what can I say? It’s a flat spell, plain and simple. Forecasts can change, but right now there’s not a single session I’d recommend. Hang the board up, maybe check back in a week. – Rusty

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.
