The Lowdown
Alright folks, Rusty here checkin' in with the outlook for our patch.
Honestly, it's a pretty quiet spell ahead. We're in for a long stretch of small, weak surf and not much to get excited about. The water is sitting at 72°F, which is much warmer than what we'd normally expect for this time of year at Praia de Asturias, a real treat for the skin.
The first few days, right through the weekend and into the start of the week, the waves are tiny and the wind is messy. Sunday the 13th sees a weak 1 ft to 4 ft southerly swell with only light cross-shore wind, but the wave energy is low and the conditions are poor. That pattern holds through Monday with a bit more wind, and it just stays ordinary.
We finally get a bit of a window on Tuesday morning, the 15th. It’s still small—swell around 2 ft from the southeast, but the wind swings to a light cross-offshore and it cleans right up. The wave energy bumps up to a moderate level. It’s not going to set the world on fire, but it’ll be the most surfable we’ve seen so far.
The real highlight, and the only standout worth pointing to, is looking further out. On Monday the 28th of September, something finally shows up. Swell from the south-southeast builds to 5 ft in the morning, then pushes to 6 ft in the afternoon. That afternoon pulse has a very long period of 15 seconds, meaning real groundswell energy and proper shape. The combined energy jumps to a strong level, which is a world apart from the rest of this outlook. The wind is onshore from the east, so it’s not perfect, but the size and power will be there. That’s a day for the experienced crew, as 6 ft with that power will be too much for beginners.
For the rest of the time, there’s nothing else. We have gaps of several days with no real recommendations—just small waves and mediocre conditions. The consistent theme is, if you can get on it Tuesday the 15th or hold out for that late pulse at the end of the month, you might score. Otherwise, it’s a board-waxing, fin-checking kind of forecast.
Rusty.
