The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for Jaco Beach over the next couple of weeks.

Right off the bat, it's a slow start. Thursday and Friday are looking pretty average with small, messy swells and cross-onshore winds. You wouldn't be kicking yourself for giving it a miss.

The first real glimmer of decent surf hits on Saturday morning, the 25th of July. We've got a clean 3 ft of swell from the SW, with a period of 21 seconds – that's a proper groundswell. The wind is glassy, which is a beautiful thing, and the combined energy is strong at 627. It's a bit of a longer period, so it might stand up a little straight on a beach break, but for a small wave, that's a quality ride. It's a good one for beginners too, as it's not too big.

Then Sunday the 26th of July shapes up as the real standout. Morning and afternoon both look prime. We're looking at a slightly bigger 4 ft swell from the SW, still with that long period around 18-19 seconds, and the wind is glassy all day. The water is a touch warmer than normal for this time of year, sitting around 86°. The combined energy is hitting 889 and 918, which is strong, powerful stuff. With the glassy conditions, this is about as good as it gets for Jaco. Get on it.

The action keeps rolling into Monday the 27th with similar 4 ft SW swell and strong energy, though the wind is a little more cross-on. Tuesday the 28th of July sees the swell bump up to 4 ft and 5 ft, with a clean window on Tuesday morning. The energy is very high, around 1222, but those waves are getting into the size where it's more for the experienced crew. It's still a good option.

The second week from the 30th of July onward sees the swell back off, dropping to under 3 ft. The quality fades too, with a mix of glassy mornings and onshore afternoons. There are still some fun, clean moments on the 31st of July morning and the 1st of August morning, with glassy conditions on small 3 ft to 3 ft SW swell. It's not the big stuff, but if you're keen for a paddle, those mornings will be clean and uncrowded.

In short, you've got a small window of mediocrity, then a killer weekend on the 25th and 26th, followed by a slow fade. The 5th and 6th of August bring a bit of a pulse with some clean, glassy mornings, but the size is down. It's a solid run, so don't sleep on that Sunday.

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.
