Conchalio Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it for Conchalio. This is a beginner-friendly, fairly consistent spot that’s exposed to the west swell, and we’ve got a classic slow-burn pattern unfolding. The water temp is sitting at 86°, which is a touch above average for this time of year—nothing crazy, just a nice warm bath.

We’ve got a bit of a flat start with no real surf on offer right now. The first decent window opens up on Thursday morning, the 20th of August. It’s small, with 2 ft swell from the SW, but the wind is dead calm—glassy as glass—so it’ll be clean and fun for a beginner on a longboard. The combined energy is weak at 217, so don’t expect much push.

Friday morning the 21st is similar: 3 ft from the SSW, glassy again, with a short period of 11 seconds. It’s not going to bowl, but it’ll be rideable and clean. The energy is still weak at 298.

Saturday morning the 22nd sees a slight bump to 3 ft from the south, period still short at 11 seconds, but glassy conditions again. Energy is moderate at 426, so there’s a little more life in the water.

Now, Sunday morning the 23rd is a standout. The swell is 3 ft from the SSW, but the period lengthens to 14 seconds—that’s a proper groundswell pulse. The energy jumps to 534 (moderate), and with glassy conditions, this is going to be the cleanest, most fun wave of the first week. It’s still small enough for beginners, but that longer period will give it shape and a bit of push.

Monday morning the 24th offers 2 ft at 18 seconds—very long period. That’s a pure groundswell, and while it’s small, it’ll be glassy and clean. The energy is 418 (moderate). Just be aware, with such a long period, the sets will be spaced out, and at a beach break it might wall up a bit. But for a point or reef, it’d be magic.

We then hit a bit of a lull mid-week, with small waves and cross-onshore winds making things choppy and ordinary. Not worth paddling out.

The real fireworks show up on Saturday morning, the 29th of August. Swell jumps to 6 ft from the SSW, period 16 seconds, and the energy is massive at 1475 (strong). Winds are light and cross-offshore, so the waves will be clean and well-shaped. This is for experienced surfers only—waist to head-high plus, with a lot of power. It’s the best day of the entire outlook.

Sunday morning the 30th follows with 5 ft from the SSW, period 15 seconds, energy 1018 (strong). Again, light cross-offshore winds. This is still excellent for experienced surfers, but a notch down from Saturday.

Monday morning the 31st sees the swell dropping to 4 ft, period 14 seconds, energy 640 (moderate). Glassy conditions, so it’s a really good session for intermediate to advanced surfers.

Tuesday morning the 1st of September and Wednesday morning the 2nd both offer 4 ft and 3 ft from the SSW, with glassy conditions and solid energy in the 500s. Very good, clean waves for the experienced crew.

After that, it tails off. Thursday morning the 3rd is small and glassy, but the magic is gone.

So, the standout is hands-down Saturday the 29th of August. That 6 ft, long-period groundswell with light cross-offshore wind is the one to circle. Conchalio will be clean, punchy, and all yours for the taking. But remember, this is a beginner spot—so if you’re not comfortable in overhead surf, watch from the sand.

Rusty.
