The Lowdown
Alright, Rusty here. Let's have a look at what's on offer for Playa de Seaia over the next couple of weeks.
Right off the bat, we're looking at a pretty flat and uninspiring start. The forecast kicks off with a small, weak swell on Wednesday the 22nd and Thursday the 23rd, but the conditions are just not there. For the first several days, the wind is either cross or onshore, mixing up the water and making it a bit of a chore. The swell energy is low, with readings like 233 on Wednesday morning dropping to a meagre 72 by Thursday morning. It's surfable, but you wouldn't race to the water.
The real standout, the only one that gets my heart rate up, is Tuesday morning, the 28th of July. That's our window. We've got a clean 4ft swell running from the NNW, a period of 11 seconds giving it a bit of groundswell punch, and the best part – absolute glass. Zero wind, calm as a lake. The combined energy hits 541, which is a solid, moderate push. For a beginner-friendly break, this is about as good as it gets. The water temp is about normal for this time of year, so no shocking surprises there. Just clean, fun waves. If you can get out there, do it.
The following week is a mixed bag. After that Tuesday morning perfection, the winds get a bit messy again. There are a few more morning windows with offshore breezes, like the 31st of July and the 4th of August, but the swell sizes are dropping back down to the 2ft to 4ft range, and the energy is lower. It's surfable, but it's not going to be anything to write home about. The crowds at Playa de Seaia can be a factor sometimes, so on that Tuesday morning, expect a few other heads in the water.
So, to sum it up: the first few days are a write-off, but keep your eyes on Tuesday the 28th. That's the one. After that, it's a bit of a slow grind with small, clean but weak waves.
