Jaco Beach Surf Forecast and Surf Report

Alright, let’s talk about Jaco Beach. This is a beginner-friendly, very consistent beach break that’s exposed to the open ocean. The water is sitting around 86°, which is a touch warmer than normal for this time of year – you’ll barely need a wetsuit, just a rash guard.

The first few days are a bit of a slow burn. Thursday afternoon (6th August) is a write-off – poor surf conditions with a weak, short-period 3ft S swell and a light cross-onshore breeze. Not worth paddling out.

Then things start to look up. Friday morning (7th August) is where it gets interesting. The swell drops to 2ft but it swings to the SW with a very long period of 18 seconds. That’s proper groundswell energy, and the combined energy is moderate (409). The real gem here is the glassy conditions – offshore wind and no ripples. It’ll be clean, but the swell is small, so it’s mellow fun for the longboard or foamie crew. The afternoon gets messy with a risk of thunderstorms and a cross-on breeze.

Saturday and Sunday mornings (8th and 9th August) follow the same pattern: glassy conditions, clean 3ft SW swell with decent periods (16 to 14 seconds), and moderate energy (493 and 315). These are your best bets for the first week if you want silky smooth waves without the crowds. Just remember, the afternoons are dodgy with storms and light onshore winds.

The real standout, though, is Saturday morning, 15th August. The swell builds to 4ft from the SW with a 16-second period, and the combined energy jumps to a strong 1183. The wind is glassy from the NE. This is excellent surf for experienced surfers – the waves will have push and shape, but keep in mind this is a beach break, so that long period might make the waves a bit straight. Still, for a more confident surfer, this is the best session on the cards.

The mornings of the 14th, 16th, and 17th August also offer very good conditions with 3ft to 4ft SW swell, glassy winds, and strong energy readings (781, 686, 597). Those are solid, clean options.

After the 18th, the swell drops back and the consistency wavers. The 20th August morning has a clean 3ft SW swell with an offshore wind, but by the 21st, it’s mostly poor again with a choppy cross-on breeze and weak energy.

Overall, the best of the window is the 15th August morning for the stronger swell and glassy conditions, with the 7th, 8th, 9th, 14th, 16th, and 17th mornings offering clean, fun, smaller waves. Crowds are likely at Jaco Beach, especially on the glassy mornings, but that’s the price for such consistent, user-friendly conditions.
