The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaking for the next couple of weeks.

We’ve got a solid run of surf coming through, starting this Monday morning, July 27th. The standout is definitely Jaco Beach, with a very long-period groundswell from the SW pushing in at 4ft and a period of 19 seconds. The combined energy is strong at (1191), and with glassy, offshore NE winds at just 3 mph, it’s going to be clean as a whistle. The water is sitting at 86°, which is a touch warmer than normal for this time of year. This is a proper setup for experienced surfers – those long-period swells really wrap in here, and the consistency is very reliable. If you’re looking to get out early, Monday morning is the pick of the week.

Tuesday morning, the 28th, is another cracker. The swell holds at 4ft from the SW, period still a solid 17 seconds, and again glassy offshore ENE winds at 3 mph. The energy is pumping even higher at (1208). It’s almost a repeat of the day before – clean, powerful, and waiting for you.

By Wednesday morning, the 29th, the wind drops to absolutely calm, 0 mph. The swell is still a fun 4ft from the SW, though the period has dropped a touch to 16 seconds, and the energy is still moderate at (940). It’s glassy, it’s clean, and it’s going to be a great session for anyone who can handle a bit of size.

There’s a bit of a drop-off after that. Thursday and Friday mornings are still glassy but the swell backs down to 4ft and 3ft respectively. The energy drops too (487 and 293). Still fun, but not the same punch. The afternoons get a bit tricky with onshore winds and thunderstorms cropping up.

Heading into the first week of August, the swell goes quiet. From Saturday the 1st through to Wednesday the 6th, we’re looking at waist-high dribble at best, with the swell dropping to 2ft to 3ft. The energy is weak (under 300), and the period is short. This stretch is a bit of a write-off for quality paddle surfing. There’s a couple of glassy mornings on the 4th and 5th, but the waves are just too small to get excited about.

The pattern starts to look more interesting again on Friday, August 7th. A new SW groundswell rolls in at 2ft but with a very long period of 18 seconds, and the energy climbs to (264). The wind is light and glassy from the east. It’s a sign of life. Saturday the 8th builds on that – 3ft from the SSW, period 16 seconds, energy at (491), and glassy conditions in the morning. This is promising.

The real long-range standout is shaping up for Tuesday, August 11th. The morning shows a 2ft SSW swell with a very long period of 16 seconds, and the combined energy jumps to (500). The wind is light and glassy from the NNE. The afternoon looks tidy too, with clean cross-off winds. This is a solid option for the second week – it’s a bit far out, so keep an eye on it, but the signs are good.

So, the best on offer: Monday morning, July 27th, and Tuesday morning, August 11th, are the two standouts. The first is a sure thing, the second is a promising look ahead.

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.
