Alright, this is Rusty coming to you live from right here at Jaco Beach. We've got a mixed bag coming up, but there are definitely some windows to get wet.

The pattern starts on the very first day, and we're kicking off with some sweet conditions. That south-southwest swell is going to be a constant companion for this whole run, and it's a long-period groundswell, so it's got some proper energy in the water (combined energy around 850+). The water's sitting at a very warm 87°, which is *much warmer than normal* for this time of year, so expect a bath.

The standout of the whole outlook is hands down Thursday morning, July 2nd. We're looking at a clean 2ft of swell from the SSW with a long 19-second period. The wind is glassy out of the NNE, and the sky is clear. It’s not huge, but the quality will be premium, perfect for logging some smooth rides. This is the best on offer early.

The energy picks up through Friday and Saturday, but the wind turns a bit wonky, creating some cross-onshore chop. It’s not junk, but it won't be as pretty as that Thursday morning.

Then we get to Tuesday morning, July 7th. This is the other true standout. The swell is up to a manageable 4ft from the SSW, with a very long 18-second period. Combined energy is over 1000 (1071), which is a solid dose of power. Paired with glassy conditions out of the north, this is prime time for a longer, rippable session. That solid groundswell will be lining up nicely; just keep an eye on the sets as they’ll have some time between them.

After that, we settle into a pattern of smaller, cleaner mornings for the next week. The energy drops a bit, but there are plenty of glassy windows, especially in the mornings. Thursday morning, July 9th looks clean with a 3ft SSW swell, and Saturday morning, July 11th has a bit more size at 4ft under calm winds.

Things start to taper off significantly around July 13th. The swell drops under 3ft and the energy (250 or less) gets weak. From July 14th into the 17th, the surf gets pretty small and weak. There are still some clean, glassy moments, like Tuesday afternoon the 14th and Wednesday morning the 15th, but it’s finicky with some cross-onshore and cross-shore winds returning. The last, cleanest little window in that run looks like Thursday morning, July 16th, with a tiny 3ft swell.

So, for the next 16 days, aim for those early mornings. It's mostly a consistent run, especially the first week. Crowds are a possibility here at Jaco—it can get busy, so the early bird catches the wave.

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.
