The Lowdown
Alright, Rusty here. Let’s have a look at what Playa de Seaia has in store.
Honestly, for the next week and a half, it’s pretty grim. We’ve got a long stretch of poor surf conditions from this Wednesday morning all the way through to the 19th of August. The wind is mostly onshore or cross-onshore, and the wave quality is rubbish. There are a few days with knee-high swell, but it’s not worth getting wet for, especially with that constant wind chopping everything up. On Saturday the 15th, the swell bumps up to around 6ft, but it’s a short-period, wind-driven N swell with fresh onshore wind – pure mess. The combined wave energy hits 400 (moderate) that morning, but it’s just not surfable.
Then, finally, a proper glimmer. On the morning of Thursday the 20th of August, we get a window of something special. The wind goes glassy from the north – practically dead calm – and there’s a solid 7ft N swell at 7 seconds. The combined energy reading is 659 (strong). The sea will be clean, glassy, and that’s the best wave of the whole outlook. That morning is the standout. It’s a bit of a short period, so it’ll be a bit lumpy at the beach but for a few hours, it’s gonna be fun. After that, the wind swings onshore again in the afternoon, so that window is tight.
Following that, we slide into another rough patch. Friday the 21st through the 24th is back to onshore and cross-onshore winds and deteriorating surf. The swell sticks around, but the conditions are poor.
Right at the tail end, on Tuesday the 25th of August morning, we see a small improvement. A 2ft WNW swell with a light cross-offshore wind from the west gives us clean, surfable waves. The wave comment says “very ordinary conditions” but the surface will be clean, and that’s a step up. The energy is low (111), but if you’re desperate for a splash, it’s rideable. Wednesday the 26th is also clean in the morning, but the swell is small and the period is a bit mixed.
So, to sum it up: the standout is the morning of the 20th of August – get up early for that glassy, chest-high north swell. The second week offers a couple of clean, small days on the 25th and 26th, but nothing that’s gonna blow your mind. The water temp is about average for the time of year.
Rusty.
