The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the horizon.
The window opens up Saturday morning, July 25th, with a clean little pulse. The main event, though, builds over the next few days, with Monday and Tuesday looking like the real standouts. After that, it fades into smaller, cleaner morning sessions before a bit of a lull, then a pick-up towards the start of August.
Here’s how it shakes out.
Jaco Beach
We kick off Saturday morning, July 25th, with some real nice conditions. The water is a touch warmer than normal at 86°F, which is notable. It’s glassy calm, with a clean 3 ft SW swell. The period is a very long 21 seconds, so this is pure groundswell – plenty of energy (moderate at 621) and those long, lined-up waves. That kind of period can make a beach break a bit straight, but with that calm wind, it’ll be worth a look. Crowds are sometimes an issue here, so get in early.
Sunday morning, July 26th, keeps the good times rolling. Glassy conditions again with a NNW breeze, and the swell pushes up to 4 ft from the SW. The period drops slightly to 19 seconds, but still long. Combined energy is strong (911). Another very clean morning.
Now, the standout. Monday morning, July 27th, is where it’s at. The swell holds at a solid 4 ft from the SW, with a long 19-second period. The wind is glassy from the N, and the combined energy kicks up to 1191 (strong). This is excellent surf for experienced surfers. The size is manageable for most, but the power and length will be the real draw. Tuesday morning, July 28th, is a close second. The swell picks up a touch to 4 ft from the SW. It’s glassy calm again, and the energy is strong (1184). The period is a bit shorter at 17 seconds, but still solid. Both Monday and Tuesday mornings are the top of the menu.
Wednesday morning, July 29th, is still very good. The swell is 4 ft, period is 16 seconds, and it’s glassy. Combined energy is moderate (939). You’ll get waves.
After that, things taper off. Thursday, July 30th, and Friday, July 31st, offer smaller morning sessions with glassy wind and swell dropping from 4 ft to 3 ft. The energy fades to moderate (485 and 353). Still surfable, just less punch.
There’s a real gap then. From Saturday, August 1st, through to Wednesday, August 5th, the mornings are small and weak. The swell drops to 2 ft or 1 ft, and the energy is weak (under 260). It’s pretty ordinary. Not a lot to get excited about.
The window opens back up Thursday morning, August 6th. A new, longer-period S swell (17 seconds) rolls in at 2 ft, with a moderate energy (244). It’s glassy. By Friday morning, August 7th, the swell is 3 ft from the SSW, period 14 seconds, and it’s glassy again. The energy is building (443). It’s a return to form.
And then, another solid morning on Saturday, August 8th. The swell is back up to 4 ft from the S, with a 13-second period. Glassy wind from the N, and strong energy (620). That’s a good one to end the forecast on.
So, if you’re picking a day, Monday, July 27th, and Tuesday, July 28th, are the clear winners. Get out there for the glassy morning sessions.
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.
