The Lowdown
Alright, let’s get into it. The next couple of weeks are looking pretty flat for our stretch of coast, with only one real window of interest right at the end of the forecast. So, strap in.
Porsmilin (Finistère) – The first week to ten days are going to be a real test of patience. From Monday the 3rd right through to the 14th, it’s a whole lot of nothing. We’ve got small, weak swells, mostly under 3 feet, and heaps of onshore or cross-onshore wind chopping it all up. There are a few glimmers, like the glassy morning on Friday the 7th with light winds, but the swell is tiny and weak – combined energy down around 41. You’d be paddling for knee-high slop. Not worth the rubber.
The middle of the month sees a slight pulse, but it’s still pretty poor. The wind swings offshore from the north from the 10th, cleaning things up, but the swell just doesn’t have any push. The energy is still weak (57 and 37 values), and the waves are just ankle-biters. The period is short too, so no real power behind them. It’s clean, but it’s just not surfable in any meaningful way.
Now, the light at the end of the tunnel. Around the 15th and 16th, we start to see a more defined west-northwest swell pushing in. Heights climb to 5 to 5 feet, and the period stretches to 9 seconds. It’s still marked as marginal, with the wind being a bit on the cross-off for the Saturday afternoon, but there’s finally some energy. The combined energy jumps to 288 and then 328 on that Saturday afternoon – a massive step up from the flatness before it. It’s only a 1/5 rating for quality, but it’s something to keep an eye on.
The real standout, though, is Monday the 17th morning. That’s the one. We’ve got 5 feet of west-northwest swell with a gentle offshore breeze from the north-northeast. The guidance flags “expect good surf conditions.” The sandbar should hold up, the waves will have some shape, and with that offshore wind, it’ll be clean. It’s not huge, but it’s the best on offer by a long shot. The combined energy is strong, at 306, which means there’s a decent amount of push in the water. This is your window. Get on it if you can.
After that, the Tuesday looks like it gets a bit mixed up with cross-shore winds, so don’t sleep on Monday.
So, there you have it. A long flat spell, but a promising finish. Keep the faith.

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