The Lowdown

Alright, this is Rusty here, and I’ve been staring at the charts for your local stretch. Let’s talk about what’s heading our way over the next couple of weeks.

First up, the water temp is sitting at about 86°, which is a touch warmer than what you’d normally expect for this time of year. That’s a nice little bonus for a tropical session.

Kicking things off, we’ve got some small but very clean surf showing on the morning of Friday, July 31st at Jaco Beach. This is the spot to be for a morning paddle. We’re looking at a 3ft swell rolling in from the southwest, and the wind is glassy out of the north at just 3 mph. That’s about as clean as it gets. The combined swell energy is moderate (296), and with that 14-second period it’s a proper groundswell, giving you some decent shape. It’s a beach break, so that long period might make it a bit straight, but for the size, it’ll be fun. The crowds are "sometimes" an issue here, but on a Friday morning, it should be manageable.

Moving into the weekend, Saturday August 1st also looks like a solid shout for the early session. Again at Jaco Beach, you’ve got a 2ft SW swell with absolutely zero wind – glassy as a mirror. The energy is still moderate (229), and it’s clean fun for a small-wave board.

We hit a bit of a lull through the middle of the week, with smaller waves and more onshore afternoon winds kicking up some chop. Not much to write home about there. You'll get some glassy mornings on August 3rd and 4th, but the swell drops right down to 2ft - 3ft, and the period on the 4th and 5th drops to a choppy 8-9 seconds. It’s surfable but nothing special.

Now, here’s what I’m really buzzing about. The real standout is shaping up for the mornings of Wednesday August 12th and Thursday August 13th. This is the one to circle on your calendar. On Wednesday morning, Jaco Beach gets a 2ft swell from the southwest with a very long 19-second period. The combined wave energy is strong at 620, so there’s plenty of push for the size. It’s dead calm, glassy conditions. That Thursday morning is even a touch bigger, with 3ft from the SW, a 17-second period, and again glassy winds out of the northeast. The energy is very strong at 642. These are proper, long-period groundswells hitting an exposed beach break, so the sets will be clean, well-spaced, and make paddling out a breeze. This is the best on offer over the whole outlook.

For the following week, August 14th and 15th still hold some good morning glass with 3ft SW swell and decent 15-second periods, but the magic of that 12th and 13th is the clear winner here.

Overall, the first week is all about the early mornings for clean, small waves, and the second week builds into a proper, promising swell window. Lock in those mid-August mornings.

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.
