The Lowdown
Right then, let's have a look at what's on offer for the next couple of weeks here at Jaco Beach. It's a bit of a mixed bag, but there are some proper windows of opportunity if you're patient.
The water is sitting at a lovely 87°, and it's a touch warmer than normal for this time of year, so you can leave the thick steamer at home.
Alright, the first bit of surf to get excited about kicks off on Monday afternoon, the 13th of July. We've got a clean 3ft swell rolling in from the SSW, with a nice long period of 13 seconds. The wind is a light cross-off, so conditions will be pretty good, and the energy is solidly moderate at 430. It's not huge, but it's a promising start for a beginner-friendly beach break that's very consistent.
Tuesday morning, the 14th, sees the swell bump up to 3ft, still from the SSW with a 14 second period. The wind goes cross, but it's only a 3 mph breeze, so the ripples will be small. The afternoon brings a light cross-on wind, so the morning is definitely the better call.
Now, here's where it gets interesting. Wednesday the 15th morning is a standout. We've got a near-perfect 3ft swell, and the wind is glassy. Absolutely glassy. That means perfect, smooth conditions on a 13-second SSW groundswell. That is a real treat for a morning session.
Thursday the 16th and Friday the 17th mornings are also offering glassy conditions with similar sized swell. It's a pattern of small, clean, and very surfable. For a spot that's super consistent, this is a nice run.
Saturday the 18th morning sees a light offshore breeze with a 3ft SSW swell, keeping things clean. The wind stays favourable right through to the end of the week, with more glassy or light offshore conditions forecast.
Then we hit a real highlight. Sunday the 19th morning is looking mint. A glassy morning, 3ft swell from the S, but the energy has kicked up a gear to 524 (moderate/strong). The real gem, though, is Monday the 20th. We've got a glassy morning with a 3ft SSW swell, and then the afternoon goes glassy again with a 3ft SW swell that has a very long 16 second period. That's a proper groundswell. The energy is pumping at 580. Expect long, clean lines.
The following week continues to deliver some fine mornings. Tuesday the 21st is dead calm and glassy with a 3ft SW swell. Wednesday the 22nd is similar.
Keep an eye on Saturday the 25th though – the wind picks up to a moderate 12 mph cross-off, so while the wave energy is moderate, the setup is looking more interesting for kite surfing than a standard paddle session. The swell period is a very long 21 seconds from the SW.
The final few days are the best on offer overall. Sunday the 26th of July morning has a clean 3ft SW swell with strong energy (686). Monday the 27th morning is dead calm and glassy with a 3ft SW swell and very strong energy (607). But the absolute standout of the whole two weeks looks like Tuesday the 28th of July morning. Glassy conditions, a clean 3ft SW swell, and massive combined energy of 593. That's a serious amount of push for the size. Get on it.

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.
