Table - best surf conditions forecast for Jaco Beach over the next 16 days.
Alright, let's talk about Jaco Beach. This spot is a beginner-friendly, exposed beach break that’s super consistent. The water is a touch warmer than average for this time of year, sitting at 87°F. The best swell direction is from the SSW, and that’s what we’re mostly looking at.
First few days are a bit of a dud. Saturday the 11th and Sunday the 12th are marginal with only 3ft surf. Monday the 13th is even worse – poor conditions, so skip it.
Things start to turn around on Tuesday the 14th. That morning you’ve got glassy 3ft swell from the SSW with a 14-second period, and the energy is moderate (420). The wind is light and glassy – that’s a green light to paddle. Wednesday the 15th and Thursday the 16th mornings also offer glassy conditions with a similar 3ft swell, but Thursday morning is dead calm (0 mph wind), making it a real standout for a clean session. Friday the 17th is a bit smaller at 2ft but still glassy.
The first real standout is Monday the 20th. The morning brings clear skies, glassy wind, and 2ft of swell from the SW with a very long 16-second period, energy of 554. That’s a proper groundswell, and with those conditions, the waves will have some real shape. Perfect for a longboard.
Then, Tuesday the 21st and Wednesday the 22nd mornings are also looking very good – glassy, clean, with 3ft of SSW swell. The energy is building, hitting 661 on Tuesday and 708 on Wednesday. That’s strong wave energy, and with the glassy conditions, it’s going to be fun.
The biggest standout of the whole outlook is Saturday the 25th afternoon. You’ll get a glassy 3ft of SW swell, with a very long 21-second period, and the energy is massive at 945 (strong). That’s a classic, clean, long-period groundswell. The waves will be drawn and powerful, perfect for a point break, but at Jaco Beach, it’ll still be a treat. Sunday the 26th morning has a bigger 4ft swell, but it’s cross-onshore, so not as clean.
Overall, the best bet is to aim for the Tuesday the 14th morning, Thursday the 16th morning, and then absolutely lock in the Monday the 20th morning and Saturday the 25th afternoon. The last week has some promising windows, but the confidence is lower that far out.

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.
