Playa de Arrigunaga Surf Forecast and Surf Report

Alright friends, Rusty here. Let’s get into this next stretch of days. It’s a bit of a slow burn, but there’s light at the end of the tunnel.

The first part of this run is pretty lackluster. The surf is small and the winds aren't doing us any favors. We're looking at a few days of waiting before anything worthwhile shows up. From Tuesday afternoon all the way through the following Saturday morning, it’s flat and bumpy or just plain weak, so don't get your hopes up for a mid-week session.

The first real green light comes on Thursday the 10th in the morning. Playa de Arrigunaga cleans right up with a light offshore from the southeast. You’ll find some chest to head-high waves in the 4ft range from the NNW, with a 10-second interval. The energy is moderate at 333, and that offshore breeze is the key. It’s not a day for heroics, but it's the first decent chance to get wet and have the waves to yourself. The water is sitting at 72°F, which is a touch warmer than usual for this time of year, so that’s a nice bonus.

Then we flatline again for a few days. After Thursday, it drops out and you’re waiting through the weekend, but keep your eyes on Sunday, September 13th. That’s the standout. The morning looks special: minimal wind with a proper groundswell from the NW at 5ft, and the period is a solid 13 seconds. That’s a long-period swell, the kind that really puts some push in the lines. The energy is strong at 668, and with light offshore winds, this is the session to circle. The swell direction is right in line with what this spot wants, which is a big plus.

The following Monday morning, September 14th, still has some quality left with a 4ft NNW swell, a 12-second period, and glassy conditions, but I'd say Sunday has the better mix of size, period, and power. On Monday afternoon the wind switches to a cross-shore, so the window is definitely the morning.

After that, the week turns messy. We get a bump in size mid-week, but that comes with onshore winds and chop, making it ugly and not worth the paddle out. That stretch from the 15th through the 18th looks poor. Keep your board in the car, but don’t hold your breath.

Looking at the second week, things are less certain. There’s a glimmer of hope around September 23rd. A good-sized, long-period swell shows up, but the period is pushing 17 seconds, which is really long. The energy gets strong, but the wind is fickle. It's promising, but it's far out, so treat it as a maybe.

So, if you can, get out on Thursday the 10th for a clean but modest session, and definitely don't miss the morning of Sunday the 13th. That's the one.

Rusty, out.
