Table - best surf conditions forecast for Jaco Beach over the next 16 days.
Right then, let’s lay it out. We’ve got some good bits and some so-so bits for Jaco Beach over the next couple weeks.
First real chance to get wet is Friday, July 10th in the afternoon. It’s flat calm, glassy as a mirror, with a 3 ft SSW groundswell running on a very long 15-second period. That’s proper energy, giving a combined swell energy reading of 608 (moderate). The water’s 86°, so a touch warmer than usual for now.
Saturday morning, July 11th, the swell bumps up to 4 ft, still a long 16 seconds, but the wind gets messy, blowing cross-onshore. The afternoons are similar for a couple days. The glossy mornings come back around Monday, July 13th: glassy again, 3 ft of clean SSW swell. On Thursday morning the 16th and Friday morning the 17th, it’s also glassy with similar size.
The absolute pick of the run is Sunday morning, July 19th. You’ve got 4 ft of SSW groundswell, 13-second period, glassy conditions. The energy is 577 (moderate). It’s a morning to be out early before any seabreeze or storms stir things up. Right on its heels, Monday morning July 20th is also a beauty: only 2 ft of swell, but it’s a 16-second groundswell, glassy, 517 energy. It’ll have way more punch than the size suggests.
After that, the swell fades hard. July 23rd and 24th are weak, with energy dropping into the 100s. Then comes a wildcard: Saturday morning, July 25th. It’s a tiny 2 ft swell, but with an insane 21-second period from the SW. That’s a very long period groundswell, with 540 energy, and clean cross-offshore wind. It’s going to be clean but maybe a bit straight for the beach. Could be fun on a log or a fish.
So: the glassy mornings from July 10th, 13th, and especially July 19th and 20th are your best bets. July 25th is a curiosity call.

Information about the Jaco Beach Surf forecast
The above surf forecast table for Jaco Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaco Beach can be found by selecting the local surf guide option on the grey menu. Our Jaco Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaco Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaco Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
