The Lowdown
Alright, I’m gonna level with you – it’s been a grim stretch at El Sardinero - Segunda. We’ve had a proper flat spell chewing up the first week of this forecast, with nothing worth paddling out for from right now until late on Thursday the 20th. That’s more than a week of poor, tiny, or non-existent surf. The water’s sitting at 72° right now, which is about a degree and a half warmer than usual for this time of year – not crazy, but you feel it.
Let’s get to the only real highlight. On Thursday afternoon, the 20th of August, we finally get a pulse. Swell jumps to 5ft from the NW with a long period of 11 seconds – proper groundswell, and the combined energy reading is a strong 423. That’s real power. The wind is light cross-offshore from the WNW at just 9 mph, keeping it clean. This is the standout of the whole outlook. That swell will wrap in nicely and should offer some lined-up, well-shaped waves, especially since that longer period prefers a point or reef setup – but the beach-and-rocks here can handle it. Remember, the spot is fairly exposed to that NNW optimum direction, so it’s a perfect fit.
Friday afternoon the 21st and Saturday the 22nd go flat again – nothing. Then on Tuesday the 25th, we get another pulse. The morning is just ordinary with 4ft from the NW at only 8 seconds and cross-offshore wind – small and weak, combined energy only 160. But the afternoon on Tuesday builds: 8ft from the NW at 9 seconds – that’s a lot of water moving. Combined energy hits 809, strong. Wind is a light cross-shore from the N at 6 mph, so it should be rideable, but over 8ft this spot gets expert-only, and with a moderate period it might be a bit lumpy. Still, for the experienced crew, that’s the biggest day.
Wednesday the 26th and Thursday the 27th mornings offer small, cleanish cross-off conditions with 3ft to 4ft from the NW, combined energy around 119 to 188 – weak to moderate. Nothing to write home about, but better than the flat spell. Friday the 28th afternoon brings another modest bump: 4ft NW at 11 seconds with a combined energy of 422, but the wind is a moderate cross-offshore at 12 mph, so a bit of chop will be on it. Not the cleanest, but if you’re keen.
Bottom line: the one real stand-out is Thursday afternoon the 20th of August. That’s your window. The mid-week bump on Tuesday the 25th is big, but only for the experts. The rest is small, inconsistent, or flat. Crowds are listed as sometimes, so expect company on that Thursday session – but it’ll be worth it.
Keep an eye on the forecasts; it don’t stay this bad for long.
