Las Gramas Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s in store for Las Gramas over the next couple of weeks. Look, it’s gonna be a bit of a slow burner. We’ve got a solid run of days ahead but the real standout arrives right at the very end, so patience is the name of the game.

Right now, we’re looking at a pretty calm stretch. The water is sitting at 70°F, which is a whopping 7°F warmer than usual for this time of year – that’s some seriously unusual warmth, like the ocean’s forgotten it’s autumn.

The first surf we can consider kicks off on Tuesday, September 15th. Don’t get too excited though. We’ve got a 4 ft SW groundswell rolling in with a very long 16 second period, and the overall energy is moderate at best, with a reading of 835. The wind’s coming from the SSW at 6 mph, keeping things cross-shore, so it’s not going to be that clean. The forecast is calling it marginal, and at this size, it’s mostly for the intermediates who are just itching to get wet. The crowd factor here is "often," so you won’t be alone, but it shouldn’t be a zoo.

Wednesday the 16th is more of the same, with the swell dropping a touch. Thursday morning, September 17th, actually cleans up nicely with a clear sky and a light cross-offshore breeze from the south. The swell holds at 3 ft from the SW, and the combined energy drops to 432. It’ll be clean, but the waves will be small and pretty weak. It’s still an intermediate-friendly sandbar set-up, just don’t expect any barrels.

From there, things get pretty quiet. From Friday the 18th all the way through to Thursday the 25th, the swell dips below 3 ft, the periods are all over the place, and the wind stays mostly cross-shore. We’re talking a lot of mornings with a light breeze and small, junky surf. The energy readings slide from 459 down to 136 at their worst. Honestly, this is a big gap of nothing special. For almost a full week, you’re looking at marginal to poor conditions. It’s the kind of stretch where you’d only paddle out if you’ve got nothing else to do.

Now, things start to look a bit more promising around Friday, September 26th. The swell bumps up to 4 ft from the WSW, with a 13 second period and moderate energy of 777. Still cross-shore wind though, so it’s not glassy but it’s rideable. That trend continues through the 28th, with building swell and occasional clean windows.

But here’s the one worth circling on your calendar: Wednesday, September 30th. This is the standout. The early morning is clear, with a light offshore breeze from the south and clean conditions. The swell hits 7 ft from the south, with a short-period of 10 seconds – that’s windswell, but the energy is strong, reading 1021. It’s going to be powerful and punchy. This is strictly for experienced surfers; 7 ft with that much energy is no joke for beginners. The afternoon stays clean as the wind picks up a touch, keeping it cross-offshore. This is the day to make the call. If you can handle the size, it’s going to be the best session in this entire 16-day window.

So, short story: a slow first week with a few small clean windows, a long flat spell in the middle, and then a real bang at the end on the 30th. That’s your window.
