Jaco Beach Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on offer for the next couple of weeks.

We’ve got a nice little run of cleaner conditions coming through, but the swell is going to be on the smaller side. The real standout is going to be next Saturday morning, the 15th of August, but we’ll get to that.

The first decent window opens up on Wednesday morning, the 12th of August. The wind is glassy from the NNW at 3 mph, and the waves are a clean 2 ft from the SW. The period is a very long 16 seconds, which is proper groundswell energy. The combined swell energy is moderate (372). This long period stuff likes a point or reef, but it’s glassy, so it’ll be clean. That's the best of the early part.

Thursday the 13th and Friday morning the 14th aren't really worth a paddle. Thursday is a bit messy with cross-shore winds, and the swell drops. Friday morning the 14th, though, we see a jump up to 3 ft from the SW, with a long 18-second period and glassy NNW wind at 3 mph. The energy is still moderate (837), but it’s clean. The afternoon turns onshore, so the morning is the only window.

Now, the standout. Saturday morning, the 15th of August. This is the one. The wind is dead calm, glassy, from the ESE. The swell is 4 ft from the SW, with a period of 16 seconds. The combined energy is strong (1046). This is excellent for experienced surfers – it’s not beginner territory at that size, but for everyone else, it’s the pick of the forecast. The afternoon stays clean with a light SSE breeze, but the morning is the gold.

Sunday the 16th of August morning is still pretty good with 4 ft from the SW and a glassy north wind, but the energy drops to moderate (662). The afternoon is ruined by a cross-onshore wind.

Monday the 17th of August is a write-off in the morning, but the afternoon glass-off from the NNE at 3 mph gives us a clean 3 ft from the SW. It’s surfable, but nothing special.

After that, the swell drops. From Tuesday the 18th through to early the following week, we’re looking at smaller waves in the 2 ft to 3 ft range. There are a few glassy mornings – like Wednesday the 19th, Thursday the 20th, and Monday the 24th of August – but the size is just not there. The wind is offshore or glassy, so the conditions will be clean, but you’ll be on a longboard or a foiler.

The week of the 21st of August sees a shift to a short-period S swell at 10 seconds, which is much weaker. The energy is weak (214-318). Not great.

Tuesday the 25th of August and Wednesday the 26th of August mornings are glassy with a tiny 1 ft to 2 ft SW groundswell. It’s surfable but ordinary.

The run ends on Thursday the 27th of August with a glassy morning and a glimmer of a 2 ft SW swell. It’s the last call of the forecast.

Overall, the best bet is Saturday morning, the 15th of August, for the biggest, cleanest waves. The other mornings are all about small, clean conditions. There's a big gap of poor afternoon surf, so stick to the dawn patrols.

Rusty.
