The Lowdown
Alright, Rusty here. Let’s talk about what’s shaping up at La Barra.
We’ve got a solid run of surf on the way, starting this Saturday morning and stretching all the way to the end of the month. Right off the bat, Saturday the 15th is a cracker. The water’s sitting at a warm 88°, which is a touch warmer than normal for this time of year – you’ll be happy in just a spring suit. The swell is a clean 4ft from the SSW, with a very long period of 16 seconds, giving it real groundswell push. The combined energy is moderate (831). And the wind? Dead glass. That means La Barra (river/jetty) will be smooth, lined up, and offering some proper waves. This is your standout session – get out there early.
The afternoon kicks up a cross-onshore breeze and chops things up, so the fun is definitely in the morning.
Sunday the 16th is another early bird special. 4ft of SW swell, still a long period of 15 seconds, and glassy conditions again in the morning with light energy dropping slightly (533). It’ll be clean and fun, just a touch smaller than Saturday. Afternoon blows out again.
Monday the 17th carries on the pattern with a smaller 3ft swell from the SSW, but again, glassy winds in the morning. It’s a bit weaker (421), but still worth a paddle before the wind turns cross-onshore.
The next few days through Tuesday and Wednesday mornings offer early windows, but the swell drops a bit, hovering around 3ft to 4ft. Wednesday afternoon gets a shorter period, choppier vibe. Still, the mornings have that glassy window.
Thursday the 20th and Friday the 21st are worth a mention. Thursday morning has a 4ft S swell with a short period of 9 seconds, but glassy winds make it workable (399). Friday morning sees a clean, cross-off breeze with 3ft S swell. It’s not huge, but clean.
We hit a bit of a lull from the 24th through the 27th. The swell drops to 1ft – 2ft, and combined energy falls below 400. The mornings are glassy, but the waves are small and weak. It’s a workable paddle if you’re desperate, but nothing to write home about.
Then, from the 28th onward, things pick up again. Friday the 28th morning is glassy with 3ft from the SSW, a long 16-second period, and combined energy jumping back to 544 – a strong moderate pulse. Saturday the 29th and Sunday the 30th are similar, with the 30th showing 4ft from the SSW, 15-second period, glassy conditions, and a combined energy of 624. That Sunday morning (August 30th) is shaping up as another true standout, right up there with the first Saturday. Clean, solid, and well worth marking on your calendar.
Overall, the pattern is classic: mornings are the golden windows, with winds going onshore by lunch most days. Crowds are possible at La Barra, but with these consistent early windows, you’ll find your share of waves if you’re an early riser. The long-period groundswell really suits this river/jetty setup, so expect clean, lined-up walls on the best mornings.
Keep an eye on that last Sunday of August – it’s got standout written all over it.
Rusty.

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.
