The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this forecast for Le Dossen is a tough one. The whole 16-day window is a write-off for any decent surf. Every single session is flagged as poor surf conditions, and there’s nothing to get excited about. It’s a dry spell, pure and simple.
Looking at the details, Friday the 17th starts us off with nothing. A tiny 1.0ft swell from the west, with a weak period of 8 seconds, and the combined energy is a measly 24. That’s barely a ripple. The water temperature is sitting at 61°F, which is about average for the time of year, so that’s not the issue.
We limp through the next week with waves that never get above 4ft, and even when they do, the wind is all over the place. Saturday the 19th afternoon sees a short-period 4ft swell from the northeast, but with a fresh 19 mph cross-breeze, it’s just a messy lump. The combined energy is only 120, which is still weak.
The only real increase in size comes on Saturday the 26th of July, with a 5ft swell from the west-northwest. The period is 8 seconds, and the combined energy jumps to 302, which is finally moderate. But the wind is onshore and gusting at 9 mph. For a beginner-friendly spot, 5ft is already pushing it, and with that onshore wind, it’s going to be a crumbly, choppy mess. Not worth the paddle out.
The same pattern continues into the first week of August. A few more pulses of swell, but the wind is always onshore, cross-onshore, or just not clean. The entire run is a blank. For a spot that’s fairly consistent, this is a real bummer, but sometimes the ocean just shuts down. Forecasts can change, but right now, there’s nothing to recommend. Keep the board in the car and wait for a better window.
Rusty.

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

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 Dossen 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.
