Jaco Beach Surf Forecast and Surf Report

Alright, crew, let’s break down this stretch of surf ahead. It’s gonna be a tale of two weeks, with some proper clean windows early on and a bit of a lull later.

Week one starts with a solid, long-period SW groundswell. Wednesday morning is looking real good, with a light offshore breeze and waves around 3ft at 16 seconds. It’s got some glide to it. Water’s running about 86°, which is slightly warmer than average for this time of year. The afternoon gets choppier with a cross-onshore wind and a chance of storms, so get your fill in the A.M.

Thursday the 10th is the one to circle. The swell pushes up to about 4ft from the SW with a 17-second period, and the morning is completely glassy, no wind at all. The energy in the water is strong, reading in the 900s. That’s clean, powerful surf. Friday morning is another winner, with solid 3-4ft surf and a light NE breeze keeping it smooth. Both these mornings are your best bets. The afternoons are consistently blown out by cross-shore breezes and storm clouds, so it’s a dawn patrol or nothing.

The weekend sees the swell back off. Saturday morning still has some waves, around 3ft, but it fades from there. Sunday and Monday are tiny and not worth the effort. Tuesday the 15th brings a small rebound with 2-3ft surf and a cleaner cross-offshore wind, but it’s not a standout.

Then comes a rough patch. Saturday the 19th, the swell jumps up to 5ft, but the period drops to a junk 8 seconds. With a cross-onshore wind and heavy rain, that’s a complete mess. Skip it. The next day, the 20th, is way more interesting. The period jumps back up to 19 seconds, that’s a real groundswell, and Sunday afternoon turns glassy with 2-3ft of clean swell. The energy is back up there in the 800s. That’s a sneaky-good window, even with the smaller size.

The final week from the 22nd onward looks smaller and less consistent. There are a few clean, glassy mornings, like the 22nd and 24th, but the swell is down to 2-3ft with shorter periods. It’s rideable but not special. That big pulse on the 20th is a promising long-range signal, but we’ll see if it holds.

So, for the best surf on offer, don't miss Thursday the 10th and Friday the 11th in the morning. That’s your high tide mark. Keep an eye on the 20th as a potential sleeper, but the forecast is less certain that far out.

This is Rusty, stay stoked and check the cams before you haul ass.
