The Lowdown
Alright surfers, Rusty here with the full look at what’s coming up for Playa de Seaia. We’ve got a bit of a mixed bag, but there are a couple of windows that are really going to fire.
Right off the bat, the water’s a bit chilly for this time of year, sitting at 63° and feeling a touch colder than normal. The first worthwhile surf arrives on Sunday morning, the 30th of August. We’ve got a solid 6ft swell pushing in from the WNW with a period of 9 seconds, and the combined swell energy is at a moderate 439. The wind is light offshore from the WSW, so it’ll be clean and rideable. It’s a beginner-friendly spot, so it’s a good time to get wet, but it’s not the standout of the outlook.
The real gem is Monday morning, the 31st of August. The swell jumps to 7ft from the NW, with a period of 10 seconds, and the energy is up to a strong 849. The wind is dead glassy from the north—absolutely perfect conditions. This is a true standout. The waves will be clean with that long-period groundswell, and the glassy surface will make it feel like velvet. It’s a bit too big for beginners, but for everyone else, get ready for some memorable waves.
After that, the surf drops off fast. We hit a dry spell from Tuesday the 1st of September all the way through to the weekend. There’s some swell but the wind is mostly onshore and it’s messy, so it’s not worth paddling out. The energy stays low, and the conditions are just poor. This is a proper gap of about five days with no real surf.
Things start to look interesting again on Monday, the 7th of September. The morning is glassy again with a small 4ft swell, and the afternoon picks up with a clean 5ft and cross-offshore wind. It’s surfable, but nothing special.
Then we get to Tuesday, the 8th of September. This is the other big standout. The afternoon brings a solid 7ft swell from the NNW with a 12-second period, and the combined energy is a massive 1485. The wind is blowing offshore from the WSW, so it’s going to be clean and powerful. This is for experienced surfers only—that’s a heavy, long-period groundswell that will be pitching fast. If you’ve got the skills, this is the session to aim for.
The following week is a bit of a washout with onshore winds and poor conditions until the very end. Sunday, the 13th of September, is the last real highlight. The afternoon has a solid 8ft swell from the NNW, period 13 seconds, and the energy is a very strong 1869. The wind is light offshore from the WSW again, making it excellent for experienced surfers. It’s a long way out, so keep an eye on the forecasts, but it’s looking like a proper end to the run.
The rest of the window is mainly onshore and messy, so don’t hold your breath for the final days. Get on the Monday the 31st of August and that Tuesday the 8th of September, and you’ll be smiling.
Rusty.
