The Lowdown
Mate, it’s a quiet stretch ahead for El Sardinero – Primera. The next couple of weeks are mostly flat and messy, but there’s a couple of windows that’ll get you wet if you’re keen. Water temp is sitting at 71°F with a slight positive anomaly of 2°F, so it’s a touch warmer than usual for this time of year – nice for a long session.
This Sunday afternoon (30 August) is a write-off: light rain, 15 km/h cross-off from the WNW, 4ft NW swell at 9s, energy at 267 (moderate) – but the conditions are poor. Not worth paddling out.
Your first real chance comes Monday morning (31 August): clear skies, light W breeze at 10 km/h blowing cross-off, 6ft NW swell at 10s, energy a solid 586 (moderate). The waves will be clean, with a bit of push. This is the best of the early week. Crowds are often here, so expect company.
Monday afternoon (31 August) switches to a light N cross-on, 6ft NW at 10s, energy 659 – but onshore wind ruins it. No good.
Tuesday (1 September) is mostly onshore with ENE wind, 4ft to 4ft NW – poor. Wednesday and Thursday drop to tiny, choppy junk (2ft–2ft). Then Friday morning (4 September) shows some promise again: clear, light W cross-off at 10 km/h, 3ft NW at 13s – longer period, energy 357 (moderate), but only surfable waves. Better is Friday afternoon: cross-off WNW at 15 km/h, 5ft NW at 12s, energy 526 (moderate), and clean. That’s your second highlight – a bit smaller but with that longer-period groundswell shape, and good wind. Again, expect company.
Saturday morning (5 September) has onshore ENE at 5 km/h, 5ft NNW at 13s, energy 796 (moderate to strong), but the wind is onshore, so it’s likely lumpy. After Saturday, it’s a long dry spell: from 5 September afternoon all the way through to the end of the forecast (14 September), the waves stay under 3ft, mostly onshore or glassy but tiny. The best you get is glassy mornings on 7, 9, 10, and 13 September, but those are knee-high at best – not worth suiting up.
So, you’ve got two honest windows: Monday 31 August morning and Friday 4 September afternoon. The rest is a blank. If you’re desperate, the Friday session has the longer swell period (12s) and clean cross-off – that’s your standout. Keep expectations low, though; this isn’t a firing fortnight.
