The Lowdown
Alright, let’s get into it. The next couple of weeks have a bit of a slow start, but there’s some real potential hiding in there if you’re patient. First thing’s first, there’s nothing doing right now. We’re looking at a couple of days of small, wind-blown junk before things start to clean up.
The water temp is sitting right around 63°, which is pretty much spot on for this time of year. No dramas there.
Tuesday and Wednesday are write-offs. The swell is small and the wind is all over it, mostly onshore and choppy. You’d be fighting it for nothing. Not worth the paddle.
Thursday is similar, more of the same messy onshore wind. Still nothing to get excited about.
Then, things start to turn around late Friday. The wind backs off to a light cross-offshore and there’s a bit more push in the water, maybe 5ft on the sets. It’s marginal, but the cleanest it’s been so far.
Now, Saturday (the 5th) is the first real standout. That’s your window. We’ve got a proper pulse of groundswell rolling in, 5ft+ from the WNW with an 11-second period, and the energy is up there. That’s a solid, powerful swell. The wind is light offshore in the morning, and it stays mostly offshore through the afternoon, just a bit stronger. This is the cleanest, most powerful surf of the first stretch. For Porsmilin (Bretagne), a WNW swell is right in its wheelhouse. This is the one to circle.
After that, Sunday is small again, just that leftover energy. Not much going on.
But hold on, Monday the 7th sees another pulse of longer-period energy. It’s not as big, about 3-4ft, but the period is way up, and the energy is still strong. That long-period swell will wrap in clean. Good chance of some tidy lines.
The middle of the week gets blown out again. Tuesday afternoon, Wednesday, all onshore and rough. Thursday the 10th cleans up with a light cross-offshore but the swell is down to about 3ft. A bit of a drop-off.
Friday the 11th is another one to look at. 5-6ft from the west, light offshore wind in the morning. That’s a good size for this spot and should have some push. The afternoon wind gets strong, so get on it early.
Saturday the 12th stays good, with a solid 5-6ft from the WNW in the morning and moderate offshore wind. That’s the biggest, cleanest swell of the window. It’s a touch bigger, so if you’re not comfortable in that, be careful, but for the experienced crew, that’s the pick of the second week.
After that, it fades again. Smaller surf, less energy, and we’re looking at a run of pretty ordinary conditions through to the 16th. There’s a little bump on the 15th with some long-period energy from the west, but the wind gets howling. Then the last day, Wednesday the 16th, the wind drops to glass, and there’s a small 3ft swell. Clean, but tiny.
So, for the full picture: Saturday the 5th is your first real standout, and Saturday the 12th is your second. The others are just making up the numbers. Keep an eye on that early forecast though, things can shift.

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.
