The Lowdown
Alright, grab your wettie, I’m Rusty, and I’m looking at the next 16 days for Larmor Plage. First up, this is an inconsistent spot, and this forecast is a real heartbreaking one for the most part. The water temperature is sitting at 67°F, which is pretty normal for this time of year, so you won’t need the thickest suit.
The first bit of actual hope doesn’t arrive until the morning of Friday, August 21st. That morning, we’ve got a clean, cross-offshore breeze from the WNW, with a WNW swell coming in at 4 ft and a period of 10 seconds. The combined energy is moderate at 282, and it’s the only real pocket of good surf in the whole run. The wind is light and clean, so the waves will look tidy. But don’t get too attached – by Friday afternoon, the wind swings onshore and gets fresh, turning the surf into a lumpy mess.
After that, it’s a long, dry spell. From Saturday the 22nd straight through to the end of the month, and into the first week of September, the conditions are just poor. We’ll see a mix of howling onshore winds, tiny waves, and wind chop. There’s a brief moment on the morning of Wednesday, September 2nd, where things look clean again with a light WNW offshore flow and a 4 ft WNW swell, but the energy is weak (138) and the overall conditions are just “ordinary” – not worth paddling out for. The offshore wind on the morning of September 3rd is clean, but the swell is only 3 ft and dropping fast.
Honestly, if you’re a surfer, Friday morning, August 21st is your only real window. The rest of the month looks more fun for a kite surfer if the wind gets up, but for a paddle, it’s a long wait. The inconsistency of this break means a blank run like this isn’t totally unusual, but it’s still a bummer. Forecasts can always change, so keep an eye on it, but for now, I’d hang the board up for a week or two.
Rusty.

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).
