Alright, let’s talk about Jaco Beach. This place is pretty consistent, so we’ve got waves coming through the next couple weeks. Mornings are where it’s at – glassy conditions and clean lines. The afternoons tend to get a bit messy with those risk of thunderstorms and cross-onshore breezes, so set your alarm early.
The first standout is Tuesday July 7 morning. We’ve got a 4ft SW groundswell with a very long 18-second period – that means deepwater energy, proper shape, and longer lulls between sets. Combined swell energy is moderate at 948. Glassy as can be. That’s a magic window. Crowds are possible here sometimes, so get it while it’s clean.
Wednesday July 8 morning is another cracker – 4ft SSW, 16-second period, still glassy. Slightly bigger but still super clean. Energy is moderate (912). That 16-second period will push through nicely. Both these mornings are prime for the beach break – just keep in mind that a long-period swell like that can sometimes make a beach break a bit straight, but with offshore/glassy wind, it’ll be lined up.
The next week has more good morning windows: Thursday July 9 morning has 3ft SSW, 15-second period, glassy – smaller but still fun. Saturday July 11 morning brings back 4ft SSW, 16-second period, glassy. Tuesday July 14 morning has 4ft SSW, 14-second period, glassy – still nice.
Then there’s a gap in quality from around the weekend of July 17–18 where surf drops off, with onshore winds and weaker swell. But hold tight – Monday July 20 morning shows a new pulse: 3ft S, 18-second period, but the wind is light cross-shore, not glassy – still moderate energy (1027). The real gem comes Tuesday July 21 morning: 4ft S, 16-second period, glassy, combined energy 906 – that’s a solid morning. And Wednesday July 22 morning follows with 4ft S, 14-second period, glassy.
For the long-range stuff, keep in mind it’s less certain, but Tuesday July 21 is looking like the best bet after the first week. All in all, get it while it’s glassy, and don’t sleep on those early windows.

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.
