The Lowdown
Alright, this is Rusty, and I’ve got the lowdown on Playa de Seaia for the next couple of weeks.
Alright, listen up, the surf is a bit of a slow burner here at Playa de Seaia. The first few days are pretty ordinary, with small, weak waves and messy conditions. But if you’ve got patience, the end of the first week and into the second week look like they’ll deliver the goods.
Things start off real quiet. Monday morning the 24th there’s a tiny 3ft swell from the NNE with a short period, and combined energy is a weak 134. It’s glassy, which is nice, but the waves are just ordinary. The afternoon gets even worse. Tuesday and Wednesday are a write-off with poor conditions and onshore wind. The only real standouts begin to show late in the week.
Thursday morning the 27th sees a jump in size with a 7ft swell from the west, but the wind is a stiff 19 mph offshore from the SSW, making it hard to paddle into. The combined energy is ramping up to 907, but it’s still a marginal call. The real highlight is Friday morning the 28th. That’s the best session on offer. We’ve got a clean 8ft swell from the WNW with a 10-second period, strong offshore wind from the WSW, and the combined energy is pumping at 1124. That’s moderate to strong energy, and the forecast says “expect very good surf conditions.” This one is for the experienced crew, though – 8ft is getting solid. Saturday the 29th still has some fun 6ft waves from the NW with clean conditions, but the energy is a bit lower.
The second week gets a bit patchy again. After a decent Sunday the 30th, the surf drops off and the winds turn onshore for most of Monday the 31st through Wednesday the 3rd of September. There’s a little window on Thursday morning the 3rd with a 5ft NW swell and glassy conditions, but it’s just marginal. The final call lands on Monday morning the 7th of September. We’ve got a 3ft swell from the NNW with a very long 11-second period, glassy conditions, and the combined energy is a solid 570. The clean conditions will make the most of that long-period groundswell, which will be better for a point or reef than a straight beach break. But the real monster is Tuesday morning the 8th of September. The forecast shows a huge 10ft WNW swell, a 14-second period, and strong offshore winds. The combined energy is a massive 4412. This is excellent surf, but only for experienced surfers. It’s over 8ft, so it’s properly big and powerful.
Stick with the Friday morning the 28th and Monday morning the 7th for the cleanest, most manageable waves, and keep an eye on that monster Tuesday the 8th if you’re an expert.
