The Lowdown

Alright folks, Rusty here. Let’s look at what’s on offer for Jaco Beach. This is a long-range look, so we got a solid 16 days of forecasts ahead.

The surf is going to be a consistent story of fun, manageable waves, but with a clear standout window early on. We kick off with some proper juice, then it slowly winds down into smaller, cleaner mornings.

The first real action hits us on Sunday morning, July 26th. We’re looking at a clean 4ft SW swell with a long, 19-second period. That’s real groundswell energy, and combined with a glassy, offshores breeze from the north at 3 mph, the ocean is going to be almost perfect. The wave energy is moderate (911). The water is sitting at 86° – a touch warmer than normal for this time of year, so just a rashie will do. It’s an exposed beach break, so with that long period, it might wall up a bit, but for the size, it’ll be a blast.

Monday morning, July 27th is the real standout. Swell is holding at 4ft from the SW, still a very long 19-second period, and the energy has bumped up to moderate (1191). The wind is glassy, coming from the NE at 3 mph. This is that perfect window where the ocean is clean and lined up. For experienced surfers, this is going to be something special. It’s very consistent, so you won’t be waiting around. Expect crowds because it’s been good, but early will be worth it.

Tuesday morning, July 28th is another cracker. The swell builds a touch to 4ft from the SW, period drops slightly to 17 seconds, but the energy is still strong (1222). Glassy offshores from the NNE at 3 mph again. This is the peak of the good stuff. Still, for the intermediate crew, it’s totally manageable.

After Tuesday, the swell starts to slowly ease off. Wednesday, July 29th and Thursday, July 30th mornings are still clean with glassy conditions and 4ft to 4ft SW swell, but the period drops and the energy fades. By Friday, August 1st, we’re down to 3ft, and the waves are getting smaller each day.

There’s a long stretch from Saturday, August 2nd to Wednesday, August 6th where the surf is really small – mostly 1ft to 3ft. The mornings stay glassy, so it’s perfect for a log or a longboard, but it’s not going to get your heart pumping. The wave energy is very weak during this period (128 to 298).

Then we get a slight pulse again starting Friday, August 8th through to Monday, August 11th, with 2ft to 3ft SW and SSW swells. The mornings stay glassy, so it’s clean, but the energy is low. It’s surfable, but not a standout.

Overall, the first few days are the best. Get on it Sunday through Tuesday morning for the cleanest, most powerful waves. After that, it’s a slow fade into small, clean morning sessions.

Stay salty,
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.
