The Lowdown
Alright, let’s break down what’s happening at Playa de Seaia for the next couple of weeks.
The water temp is about 65°F, which is dead average for this time of year, so no need to worry about extra rubber.
The first real chance to get out will be on the morning of Sunday, September 6th. We’re looking at a clean 4ft swell from the NW with an 11-second period. The wind is out of the WSW, blowing offshore, which will keep the surface smooth. The combined energy is moderate at 426, so there’s a little bit of grunt behind it. For a beginner-friendly spot, this is a solid window. It gets a bit smaller in the afternoon, dropping to 3ft, but it’s still clean with a cross-offshore breeze.
Now, Monday the 7th brings a bigger pulse – 7ft from the WNW with a 12-second period, and the energy is strong at 1102. But the wind is from the N, blowing cross-onshore, and that’s going to chop it up. The same story in the afternoon. This one looks more like a kite-surfing setup than a good paddle session.
The standout window, hands down, is Tuesday morning the 8th. The wind is glassy – SSE at just 3 mph – and the swell is a clean 5ft from the WNW with a 9-second period. The energy is moderate at 313. It’s not big, but for a beginner break, that’s perfect, clean, and fun. This is the best session you’ll see.
After that, it’s a rough stretch. From Wednesday the 9th through the 13th, the wind is onshore or cross-onshore, and the swell is either too small or just ugly. The energy drops right off. There’s a real dry spell there.
We get a slight chance on the morning of the 14th, but the swell is a short-period 6ft from the NE at just 6 seconds, with a cross-shore wind. It’s marginal. The energy is moderate at 423, but that short period makes it sloppy.
The end of the week starting the 15th sees tiny waves – 2ft to 3ft – with clean offshore winds on the 16th, but it’s just too small to get pumped about. The energy is weak. The 18th brings a longer-period NW swell (14 seconds) but the height is only 3ft, and while the wind is offshore, the energy is a moderate 504. It’s clean, but you’ll be hunting for a ride.
So, to wrap it up: the best bet is the glassy morning of Tuesday the 8th. If you miss that, the Sunday the 6th is your next best option. The rest of the forecast is a washout for clean, quality waves.
