The Lowdown

G’day, Rusty here. Well, lookin’ at the next couple weeks, it’s a pretty quiet start for El Sardinero - Primera, but there are some late gems hidin’ in the back half that’ll get the heart pumpin’. We’ve got a bit of a lull to kick things off, so don’t rush down Thursday or Friday mornin’ unless you like paddlin’ around for not much.

Thursday the 20th is a write-off for surfin’. Mornin’s a mess with light rain and cross-onshore breeze, only 4ft from the NW and a weak combined energy of 316 – just poor conditions. Afternoon cleans up to glass, but the swell’s still only 4ft from NNW and the energy drops to 275, so it’s flat and ordinary. Friday the 21st holds a bit more size – 4ft in the mornin’, 6ft in the afternoon – with clean cross-off wind, but the combined energy ramps to 429 and then 595. The forecast calls it marginal, not worth gettin’ wet for unless you’re desperate.

Saturday the 22nd and Sunday the 23rd are ugly – cross-onshore winds, lumpy chop, tiny waves under 3ft, and combined energy below 100. A real flat spell. Monday the 24th is even smaller, with only 2ft waves and energy down around 22. That stretch from Thursday to Monday is a solid five-day gap with nothin’ worth paddlin’ out for.

Tuesday the 25th mornin’ shows a flicker of life: glassy conditions, 4ft from the NW, and combined energy of 113 – surfable but very ordinary. Winds go cross-onshore in the arvo. Wednesday the 26th mornin’ is actually clean with light offshore breeze from the SW, but it’s still only 3ft and energy of 105, so it’s a waist-high ankle-snapper at best.

Now, here’s where it gets interesting. Thursday the 27th mornin’ has clean cross-off wind, 6ft from the NW, and combined energy of 350 – decent but the afternoon jumps to 8ft and energy of 833, which is strong. That’s gettin’ chunky for anyone but experts, and the wind turns cross-on, so it’ll be a bumpy ride. Still, there’s power.

The real standout lands Friday the 28th mornin’. Clean cross-off breeze, 6ft swell from the NW with a 10-second period, and combined energy of 688 – that’s moderate energy but well-shaped. The water’s a touch warmer than normal at 74°, which is a couple degrees above average for this time of year, so you can leave the thick wetsuit at home. This is the best session on offer for intermediates: good size, clean faces, and with that NW direction bein’ optimum for this sheltered spot, the waves should wrap in nicely. Crowds are often here, so expect some company.

Saturday the 29th mornin’ is another cracker: 6ft, NW, 9-second period, combined energy of 609, with light offshore breeze. Clean and punchy. Sunday the 30th mornin’ might be the pick of the whole run though – glassy, dead calm, 6ft from the NW, and energy of 563. Perfect for a long session if you can handle the crowd, but the swell’s under 7ft so it’s fine for competent beginners too. Monday the 31st mornin’ is also glassy with zero wind, 5ft from the NNW, and energy of 541 – another clean, fun mornin’.

Into the first week of September, Tuesday the 1st is ordinary again – small and only surfable. Wednesday the 2nd mornin’ has clean cross-off wind, 5ft from the NW with a 10-second period, and combined energy of 460 – worth a look. Thursday the 3rd mornin’ is a dead-flat glassy calm with 5ft from the NNW and energy of 500 – that’ll be buttery smooth. But note Friday the 4th afternoon brings 6ft from the NW with energy of 545, but the onshore wind makes it marginal.

Bottom line: Friday the 28th mornin’ and Sunday the 30th mornin’ are your two standouts. Good size, clean wind, solid energy. The second week has reliable mornin’s too, but less certain at range – keep an eye on that Thursday the 3rd glass-off.

Stay stoked,
Rusty
