Alright folks, Rusty here. Let’s talk Jaco Beach.
The surf is rolling in right from the start. The water temp is 87°F , which is much warmer than normal for this time of year—bare feet and boardies weather.
Friday morning, July 3rd kicks it off right. There’s a 4ft swell from the SSW with a long 16-second period. That’s proper groundswell. Combined energy is at 843 (moderate) , and the wind is dead glass from the NNW. It’s going to be mirror-clean. The direction is ideal for this exposed beach. This is the top call in the whole outlook—clean, long-period, and consistent. Crowds are a *sometimes* thing, so get out early. The score isn’t a rating, but this is your window.
Saturday, July 4th morning still has 4ft swell, but the wind goes cross-on from the NW, making it a bit lumpy. Sunday morning, July 5th brings a 3ft swell with glassy conditions again—another clean session.
Tuesday morning, July 7th is the other standout. Swell is 4ft from the SSW, but the period pushes to 18 seconds – that’s very long-period groundswell. Combined energy sits at 1076 (strong) . Wind is glassy from the N. For experts, this is excellent, but at a beach break, that long period can make the waves break straight and close out. Still, on a clean glassy morning, it’s a session to remember.
After that, the swell slowly fades. From Thursday, July 9th to Sunday, July 12th, we’ve got 3ft to 3ft swell with clean morning windows, but the energy drops off. Monday, July 13th is where we hit a real lull. From that afternoon through to Wednesday morning, July 15th, there’s a gap of just poor to marginal conditions, except for one glassy 3ft pulse on Tuesday afternoon, July 14th.
Wednesday morning, July 15th offers a clean 3ft with offshore winds from the ESE, but it’s inconsistent. The last stretch from July 16th to July 18th is tiny – 2ft to 3ft – with weak energy and mostly onshore afternoons. The big ones are Friday the 3rd and Tuesday the 7th. Don’t miss ‘em.
Stay stoked,
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.
