Alright, let’s talk about Jaco Beach. Rusty here.
The water temp is about 87°F, which feels a bit warmer than normal for this time of year – a nice treat. The surf is going to be consistent all week, nothing too big, but the morning windows are where it’s at.
Best bet is Saturday afternoon, July 4th. You’ve got a 4ft swell from the SSW with a long 15-second period, putting some real grunt into the waves. The combined energy is sitting at 695 (moderate). The wind is a light cross-offshore breeze, keeping things clean. It’s a very consistent break and the size is perfect for everyone, though crowds can pop up sometimes.
If you can get out Sunday morning, July 5th, that’s the one. The wind goes glassy – dead calm – and the swell is 3ft from the SSW with a 14-second period (589 combined energy). It’s going to be clean, smooth, and fun. The afternoon gets a cross-on breeze, so morning is the call.
Monday morning, July 6th, is another glassy winner. The swell holds at 3ft, but the period jumps to a very long 16 seconds (737 combined energy). Those long lines will wrap in nicely. Just remember, that long period can make a beach break a bit walled up, but with no wind, it’ll still be a blast.
Tuesday morning (July 7th) and Wednesday morning (July 8th) are both glassy with 4ft and 4ft swell from the SSW. Tuesday morning has that 18-second period (948 combined energy), giving it plenty of push.
After that first week, the swell backs off. The mornings from July 9th to July 11th are still clean with SSW swells around 3ft to 4ft, but nothing tops that Sunday session.
Things go quiet from the afternoon of July 13th through to the end of the week. Swell drops to 2ft - 3ft, and the wind turns onshore or cross-onshore, making it a bit of a mess.
Then, on Sunday morning, July 19th, the swell builds back to 4ft from the SSW with a 16-second period and glassy wind. The combined energy is 740 – a promising finish to the run. It’s a ways out, but worth keeping tabs on.
The moral of the story: get out early, especially that first Sunday and Monday.
Rusty.

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.
