The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming down the pipe for the next couple of weeks.
Jaco Beach is the main show, and it’s a bit of a slow burner at first. The water’s a touch warmer than normal for this time, at 86°, so you won’t need a thick wetsuit.
The first few days are pretty ordinary. Wednesday the 5th has some glassy 3ft S swell in the morning, but combined wave energy is weak (167). It’s surfable, but nothing to get excited about. Thursday the 6th morning looks better with 3ft SSW swell and glassy conditions, energy picking up a notch (212). Friday the 7th brings a longer period groundswell (18 seconds) at 2ft from the SW, but that long period might make it break a bit straight on the beach. Still, glassy morning winds make it clean.
The real standout is shaping up for Saturday the 15th. The morning session is looking excellent: 5ft SW swell, glassy offshore N wind, and combined wave energy of 1126 – that’s strong energy. The swell direction is right on the money for the break. This is expert territory at over 4ft, so it’s for the experienced crew. The afternoon will get chopped up by a cross-shore breeze, but that morning is the one to circle.
The other big moment comes on Friday the 14th morning. Another glassy start with a 4ft SW swell from the 18-second range, and energy is pumping at 894. That’s a very good session waiting to happen, but it’s a long way off, so keep an eye on the forecasts.
There’s a gap of no real recommendations from the 5th to the 13th, but the swell builds nicely from the 14th onward. The mornings from the 14th to the 20th all look clean with glassy or near-calm winds, with the 15th being the absolute peak. After the 15th, the swell settles back to 4ft and then 4ft, still clean but not as punchy. Crowds are sometimes a thing here, so get out early for the best of it.
Rusty 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.
