The Lowdown
Alright, grab your stick, let's talk about what's coming up. La Barra is the only game in town for the next couple of weeks, and it’s got some real moments if you play your cards right.
We kick things off this Monday the 31st of August with a clean, glassy morning. Swell is a tidy 3ft from the SSW with a solid 13-second period – that’s a nice little groundswell. The water is sitting at 87°, which is a touch warmer than normal for this time of year, so the shorties are fine. The combined energy is moderate (400), so there’s enough push to have fun. It’s a river mouth setup, so those longer-period swells should line up nicely. Get it early because the afternoon turns into a choppy mess with a cross-onshore wind.
Tuesday the 1st and Wednesday the 2nd of September are rinse and repeat: glassy mornings with the swell dropping slightly to 3ft and 2ft, but the period jumps up. Wednesday morning especially, that 17-second period from the SSW gives the swell real grunt (energy at 533), making those little waves stand up and wrap around the jetty. By Thursday the 3rd, the swell is down to 2ft but the period is a ridiculous 19 seconds, energy hitting 617. It’s tiny but clean as a whistle – a longboard or a funboard will be your best mate.
Now, here’s where it gets interesting. The standout window is the morning of Friday the 4th through to Saturday the 5th of September. Friday morning we’ve got 4ft of SSW groundswell with a 17-second period, cross-offshore wind, and the combined energy is pumping at 1070. That’s moderate-to-strong energy, and the waves will be clean, lined up, and holding plenty of shape. This is the best of the run for experienced surfers – those 4ft sets will feel a lot bigger with that long period pushing them in.
Saturday the 5th morning is another beauty: 5ft from the SSW, 16-second period, glassy, and the energy is at 1225 (strong). That’s borderline expert territory at over 5ft for beginners, but for anyone with a bit of skill, this is a pumping session at the river mouth. The long period will make it a bit straight at times, but the jetty should groom it nicely. Afternoons on both days turn into bumpy cross-on conditions, so be out there at first light.
The following week from Sunday the 6th to Sunday the 13th sees the swell back down, mostly 2ft to 3ft, with a few clean mornings. Monday the 7th and Tuesday the 8th mornings are glassy with 3ft and 3ft, solid period around 13-14 seconds. Then there’s a little pulse on Thursday the 10th morning: 3ft with an 18-second period and energy at 818 – very clean, very fun for a small-wave grovel.
The second week tapers off. Friday the 11th morning is glassy with 3ft and a 16-second period, but the energy drops to 546. By the 12th and 13th, the swell is down to 2ft-3ft, and the afternoons are all blown out. You can still score a glassy morning session, but it’s diminishing returns. The 14th and 15th have tiny 2ft-2ft swells with long periods, making them more suitable for a longboard cruise than a proper hit.
Crowds at La Barra are *sometimes* a factor, but with this being the only recommended spot, expect a few locals on the good mornings, especially that Friday-Saturday stand-out. The river mouth will handle the groundswell better than a beach break would.
So, in short: the best bet is the morning of Friday the 4th and Saturday the 5th. Don't sleep on them. The rest of the window has plenty of clean, small-wave fun, but those two mornings are the real deal. Forecasts can always change, but this run has some proper promise.
Stay stoked.

Information about the La Barra Surf forecast
The above surf forecast table for La Barra provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at La Barra can be found by selecting the local surf guide option on the grey menu. Our La Barra 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 (La Barra) 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 La Barra 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.
La Barra is 9 km (6 miles) from San Jose. If you plan a holiday in Guatemala - Pacific Coast, look for hotels and other accommodation in San Jose. San Jose has rooms for a wide range of budgets as well as car hire and transport links.
