Jaco Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a decent stretch coming up for Jaco Beach, but it’s not all firing. The first few days are small, but we’ve got one standout morning that’s worth setting the alarm for, and a longer-range window that looks promising for the second week.

The water is sitting at a warm 86°F, which is a touch warmer than normal for this time of year, so you’ll be comfy in boardshorts or a spring suit.

We kick off on Wednesday, 29 July, with a 4ft SW swell at 16 seconds. That’s a long-period groundswell, which means nice shape and energy, but the wind is a light cross from the SSW, so it’s a bit messy. The combined energy is moderate (825). Not the best, but it’s surfable.

Thursday morning, 30 July, is the first real standout. The swell drops to 4ft from the SW, still a solid 14-second period, and the wind is glassy – zero from the ENE. That’s pure clean conditions. Combined energy is moderate (489). This is your best early window: small, but clean and lined up. Thursday afternoon gets a bit bumpy with a light cross breeze.

Friday morning, 31 July, is another glassy morning with a 3ft SW swell at 14 seconds. Clean again, but smaller. The afternoons this week are generally a write-off with afternoon storms and cross winds.

Saturday morning, 1 August, stays glassy but the swell bottoms out at 2ft. It’s clean but tiny. From Sunday, 2 August, through to Wednesday, 6 August, the swell is small and the wind is mostly cross-on or choppy. Energy drops below 300. It’s a flat spell. Not much to get excited about.

Then we hit a change. Friday morning, 7 August, looks promising. It’s glassy again with a 2ft SSW swell, but the period jumps to 18 seconds – very long-period groundswell. Combined energy climbs to 441. That’s a sign of better energy to come. It’s small, but with that period and glass, it’ll be clean and fun for a longboard.

Saturday morning, 8 August, sees the swell build to 3ft from the SSW, 16 seconds, with a light cross breeze. Energy is now 674 (moderate). It’s improving.

But the real standout of the second week is Monday morning, 10 August. Glassy conditions, a 2ft SW swell with a 21-second period – that’s a very long-period groundswell. Combined energy is 523. That’s a gorgeous combination: clean, glassy, and that long period will wrap around the beach well. It’s small, but it’ll be quality. Tuesday morning, 11 August, is glassy again with a 2ft SW swell at 19 seconds (energy 521). Another cracker.

Wednesday morning, 12 August, is glassy with a 3ft SW swell at 17 seconds (energy 633), and Thursday morning, 13 August, is glassy with a 3ft SW swell at 16 seconds (energy 538). The whole second week has a string of glassy mornings with solid groundswell. The afternoons will have storms, so get out early.

Overall, the best call is Wednesday morning, 12 August, or Thursday morning, 13 August – both are glassy, clean, and have the most size (3ft to 3ft) with excellent period. The 10th and 11th are also top-tier but smaller. Crowds are possible at Jaco Beach, so get there early.

This stretch is a classic example of “don’t sleep on the small stuff” – the quality is in the morning glass and the long-period groundswell.

Rusty.
