Jaco Beach Surf Forecast and Surf Report

G'day, I'm Rusty, and we're looking at the 16-day window here for Jaco Beach. It's a beach break that's very consistent, so even when it's not pumping, there's usually something to sit on. The water's sitting at a warm 86°, which is a touch warmer than normal for this time of year.

The next few days are a bit dialled back. We've got a little pulse of SW swell hangin' around from Friday 31 July into the weekend, but it's pretty small, around 2ft to 2ft. The real gem is the Saturday morning (1 August) – you've got a clean 2ft of SW swell, glassy conditions with a NNE breeze, and the combined energy of the swell is moderate (229). It's small but clean. Sunday morning (2 August) is also worth a mention – 2ft of SW swell, cross-off winds, and the period jumps to 15 seconds, which is a long-period groundswell that'll put some shape in the waves. The energy is moderate (236).

Monday morning (3 August) is another glassy one with 2ft of SW swell (287 energy), but the afternoons get a bit of a risk of thunderstorms and cross-on wind, so mornings are the call. The following week, from Tuesday 4 August, the swell drops right off to 3ft but with a short period of 9 seconds, and the energy dips to 275 – it's weak, messy, and the afternoons aren't worth paddling out for. This pattern of small, short-period swell continues through Wednesday 5th and Thursday 6th, with energy dropping to 143 and 108 – very weak. Honestly, the surf quality is ordinary, and the afternoon winds are no good.

Now, hold onto your board, because things start to look up from Friday 7 August. The swell direction swings to SSW, the period jumps to 17-18 seconds, and the energy climbs to 382. That Friday morning (7 August) is glassy with 2ft of SW swell, but Saturday 8 August is the real standout. Saturday morning (8 August) is dead calm, glassy, with 3ft of SSW groundswell and a solid 16-second period. The combined energy is strong (548) – that's a proper pulse. The waves will be clean and have some punch, though with that long period, it might break a bit straight at the beach, so keep an eye on the rip. Sunday morning (9 August) is also a winner with glassy conditions and 3ft of SSW swell at 14 seconds (398 energy).

The next week keeps the momentum. Monday 10 August morning is calm and glassy, 2ft of SW swell (344 energy). Tuesday 11 August is glassy again with 2ft of SW swell. Then Wednesday 12 August morning has a 2ft SW swell but a very long 18-second period (334 energy) – that's a deep-ocean groundswell, but it'll be small. Thursday 13 August morning is absolutely firing – clear skies, 3ft of SSW swell, 14-second period, and the energy is very strong at 618. That's one of the best windows. Friday 14 August morning is another cracker: 2ft of SW swell at a massive 19-second period, 617 energy, glassy. And Saturday 15 August morning – dead calm, 3ft of SW swell at 17 seconds, energy is 674 – that's the strongest energy in the whole window. That's your expert session, if you can handle the long-period lines.

The afternoons across this whole window are mostly average to poor, with cross-on winds and risk of thunderstorms. Mornings are the only go. This is a consistent setup, so it tends not to stay poor for long, and the long-range standouts from 13-15 August are promising but a bit less certain. For a beginner, the swell stays under 5ft all window, so it's manageable, but the long-period days can be a bit more challenging. The standout is definitely Saturday 15 August morning – the calmest, cleanest, and most powerful day of the lot. Crowds are possible here, as it's a very consistent spot.

Rusty out.
