Alright folks, Rusty here. Let’s talk about what’s coming up for Jaco Beach.
We’ve got a solid run of surf on the cards starting this Sunday, July 5th, and it stretches right through to the end of the 16-day window, with no real gaps to speak of. The whole pattern is driven by a consistent, long-period SSW groundswell that just keeps on giving. The water is sitting at a toasty 87°, which is a lot warmer than usual for this time of year, so you might not need a full suit.
The standout window is hands down Monday morning, July 6th. We’ve got a clean 3ft of swell coming from the SSW, with a very long period of 16 seconds, and the wind is dead calm – glassy conditions. The energy is decent (735), and for a beach break, that long period will mean some proper shaped lines rolling through. It’s a beginner-friendly size, but the quality will be for everyone.
Tuesday morning, July 7th, is another absolute beauty. The swell bumps up to 4ft from the SSW, still with a solid 18-second period, and the wind is glassy again. The energy is ramping up (1058), and those waves are going to have some real push. It’s still manageable for most, but the power is building.
Wednesday morning, July 8th, is also worth a mention. The swell holds at 4ft from the SSW, period drops a touch to 16 seconds, but the wind is light offshore from the ENE, making for clean, glassy conditions. The energy is healthy (912).
After that, the pattern stays fairly consistent through the second week, with waves in the 3ft to 4ft range and mostly clean conditions in the mornings. The crowds at Jaco Beach can be a thing sometimes, but with this much surf on offer, there’s waves for everyone.
Right at the tail end, on Monday morning, July 20th, we get another glassy morning with a 3ft swell from the SSW, but the period drops to 12 seconds, so it’ll be a bit more disorganized.
Overall, you’ve got a great run of surf here. Get out there for the glassy mornings early next week – that’s the pick of the pack.
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.
