The Lowdown
Alright, let’s get into it.
We’ve got a solid run of surf shaping up at Los Cobanos. The water’s sitting at a warm 86°F, which is pretty much spot-on average for this time of year.
The week kicks off proper on Friday morning, August 28. It’s small but clean, with 2ft of SSW swell rolling in on a long 19-second period. That’s proper groundswell, lots of energy for the size, and with glassy conditions from a light ENE breeze, it’ll be smooth making the paddle out. The combined energy is moderate (644). Nice little warm-up.
Saturday morning, August 29, is where things start firing. The swell jumps to 5ft from the SSW, still with a long 16-second period. The combined energy goes strong at 1054. Glassy conditions again from an easterly breeze. This is excellent for experienced surfers – enough push to get you a proper ride, but still clean.
Then Sunday morning, August 30, it’s 5ft from the SSW, 14-second period, combined energy at 925, and again glassy. It’s not quite groundswell like Friday’s, but still decent. The standouts for the whole outlook are definitely Saturday morning and Sunday morning – that’s where you want to be in the water.
There’s a bit of a lull in the middle of the week. Conditions stay surfable but smaller, around 2ft to 3ft, with clean mornings but afternoon onshore winds that ruin it. Tuesday and Wednesday mornings are worth a look for a quick session.
Going into the second week, the weekend of September 5 and 6 brings a bit more size. Saturday morning, September 5, has 5ft from the SSW with 16-second period and combined energy at 1295. The wind is light and cross-offshore, so it’ll be clean. This is the best of the second week, but we’re a bit further out, so take it as promising rather than locked in.
Sunday morning, September 6, has 4ft, 15-second period, and glassy conditions – another good call.
There’s a gap of flat or poor afternoon conditions through the week, but mornings consistently offer something through to September 12. The last clear standout after the first week is Saturday morning, September 5. After that, we’re looking at smaller, less consistent swell.
One thing to note: this is a beginner-friendly spot and it’s very consistent overall. The crowd factor is “sometimes,” so it can get a bit busy on those glassy mornings. Keep an eye out for that.
So, bottom line: lock in Saturday morning, August 29, and Sunday morning, August 30. Then keep an eye on Saturday morning, September 5. That’s your best windows.
