The Lowdown
Alright, Rusty here again. Let's break down what’s on the table at El Sardinero - Segunda over the next couple of weeks.
The water temp is about 71°F, which is pretty typical for this time of year—nothing too crazy.
We kick off Sunday the 30th of August morning with a clean 4ft NW swell, 9-second period, and moderate wave energy around 272. A light cross-off breeze keeps it tidy. Sunday afternoon is smaller and more ordinary.
The real highlight is Monday the 31st of August morning. A strong 6ft NW swell with a 10-second period and energy hitting 557, plus a light offshore wind from the W. That's the glassy, lined-up stuff we dream about. Monday afternoon holds size at 6ft and 647 energy, but the wind goes cross-shore, so it won't be as clean.
From Tuesday the 1st of September onwards, it’s pretty grim. Most days are flat or tiny, with onshore winds ruining what little waves show up. There’s a small bump on Friday the 4th with a 5ft long-period NW groundswell (13 seconds) and 652 energy, but it’s blowing cross-onshore—messy and not worth the drive. A glassy 2ft NW swell on Tuesday the 8th morning gives a brief moment of hope, but the size is too small to get excited about.
Long story short: Monday 31st August morning is your one and only standout. The rest of the 16-day run is mostly flat or junk.
Rusty, out.
