The Lowdown
Hey, folks, Rusty here. Let’s talk about Jaco Beach and what’s coming up over the next couple of weeks.
The forecast starts off slow on Wednesday, July 22nd. The surf is tiny – about 2ft from the SW with a 13-second period. The water's running about 86°F, which is a touch warmer than usual for this time of year. The morning has a light north wind making it a little cross, but the afternoon glass-off gives you clean, smooth waves. Combined energy is weak, only 336, so don’t expect much push.
Thursday, July 23rd is a washout. Swell jumps to 4ft but it’s short period, 8 seconds, with onshore wind from the southwest. Combined energy is 407, but the quality is poor. Skip it.
Friday, July 24th afternoon cleans up nicely with a cross-offshore breeze from the south. The swell is tiny at 2ft but has a super long period of 24 seconds, which gives those sets some shape. Combined energy is 488, moderate. It’ll be clean but small.
Saturday, July 25th is a good day. Morning brings 3ft swell, 21-second period, and glassy winds from the northeast. Combined energy is 720, getting into moderate territory. Perfect for a relaxed session. The afternoon stays clean with a light cross-offshore breeze.
Sunday, July 26th sees the swell holding at 4ft, but the wind goes cross-onshore, making it choppy. Combined energy jumps to 1000, so there’s power, but the quality isn’t there.
The standout is Tuesday, July 28th morning. Swell is 4ft from the SW, 17-second period, with glassy conditions from the north-northeast. Combined energy is 1222, which is strong. That’s excellent, clean surf for experienced surfers. Big, powerful waves with good shape.
After that, the swell winds down through the first week of August. There are more glassy mornings with small, clean surf – best bets are Saturday, August 1st afternoon with 2ft and glass, and Monday, August 3rd morning with 2ft and dead calm.
So, overall, Jaco Beach stays consistent, but the absolute standout is Tuesday, July 28th morning. If you can get out, that’s the call.
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.
