The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cooking for Jaco Beach over the next couple of weeks.

Right off the bat, Wednesday the 15th through Friday the 17th are looking pretty tasty. The water is running a touch warmer than normal for this time of year, sitting at 86°F, so you can leave the winter suit at home. We’ve got a clean, glassy morning on the 15th with a 3ft SSW swell, period around 13 seconds, and the combined energy is a solid moderate (430). That’s a nice, workable wave for a beginner-friendly spot. The standout for the early run is Friday the 17th afternoon – the wind goes glassy, and we’re looking at a 3ft SSW swell with a 13-second period and a beefier energy reading (466). It’s clean, consistent, and the best of this first window.

The mornings of the 16th and 17th are also glassy with similar 3ft to 3ft SSW swell, but the afternoon can get a bit sketchy with risk of storms. Saturday the 18th morning is glassy again with a 3ft SSW swell, but the afternoon drops off. Overall, from the 15th to the 19th, there are plenty of windows of clean, small surf for the beginner to intermediate crew.

There’s a bit of a lull in quality from the 20th through the 22nd, with a lot of marginal conditions and cross-onshore winds. The swell is still there, but the wind isn’t doing us any favors. The 21st has a couple of nice windows though – Tuesday morning the 21st features a clean 3ft SW swell with a 15-second period (486 energy), and Tuesday afternoon goes glassy with a 2ft SW swell. Those are worth a paddle if you can time it.

Now, hold onto your board shorts, because the second week has some serious potential. Friday the 25th is a real standout for the long-range. The Saturday morning session on the 25th is looking very promising – a 3ft SW swell kicking in with a very long 21-second period, and the energy jumps to 645. The wind is clean and cross-offshore. That’s a groundswell that will wrap in nicely, and the long period will give it some real punch. It’s a smaller wave, but the quality should be excellent.

Then we really get a spike. Tuesday the 28th morning is your best bet of the entire forecast. Glassy conditions, with a 4ft SW swell, a 17-second period, and the combined energy hits a very strong 1052. That’s a serious pulse of energy. The description says it’s excellent for experienced surfers, and I’d agree – at 4ft with that much period and power, it’s a step up. The 29th morning is also looking very good with a similar 4ft SW swell (16-second period, 967 energy) and glassy conditions. This is the kind of window that makes the wait worthwhile.

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.
