The Lowdown
Alright folks, Rusty here. Let’s look at what’s cooking for La Barra. It’s a river/jetty setup that’s fairly consistent, and it’s exposed to that SSW swell. The water temp is sitting around 86°, which is about average for this time of year, so no surprises there.
We’re kicking off now, but there’s a bit of a warm-up period. The first real standout session is this Thursday morning, the 30th of July. The swell is coming in at 4ft from the SSW with a solid 14-second period – that’s proper groundswell, mate. The wind is glassy, completely calm, and the wave energy is moderate (606). This is going to be clean, lined-up, and very surfable. The afternoon turns to a light cross-onshore, so get out early.
Friday morning the 31st is another good shout. Swell drops slightly to 3ft, still from the SSW, period hanging at 14 seconds, and again glassy conditions. Wave energy is moderate (401). It’s a touch smaller, but still clean and fun. Saturday morning the 1st of August is similar: 3ft, 13-second SSW swell, and glassy. Good for a paddle.
Sunday morning the 2nd is a bit smaller at 2ft, but the wind is glassy from the ENE, and the period is 12 seconds. Still clean, just smaller. Energy is lower (236), but it’s surfable. There’s a storm risk on Monday morning the 3rd, but the wind stays glassy, and you get 3ft of SSW swell at 14 seconds. Catch it before the afternoon chop.
Now, there’s a real lull from Tuesday the 4th through to Thursday the 6th of August. The swell drops to 1ft, energy dips well below 200, and it’s pretty ordinary. You could paddle out, but it’s not going to set the world on fire.
Then, and this is where it gets interesting, we have a proper run of standouts starting on Friday the 7th of August. Friday morning kicks off with a 2ft swell but the period is a massive 18 seconds – very long-period groundswell. The energy jumps to 457 (moderate), and it’s glassy. That’s the kind of swell that favours this river/jetty setup, wrapping in nicely. The afternoon on Friday is even better: 3ft, still 18 seconds, and the energy hits 651. Glassy again. This is the best on offer for the whole outlook.
Saturday the 8th of August keeps the goods coming. Morning is 3ft, 16 seconds, glassy, with energy at 618. Afternoon holds at 3ft, 16 seconds, with a light cross-offshore wind that keeps it clean. Energy is still high at 554. This is a solid run.
Sunday the 9th holds at 3ft, 14 seconds, glassy in the morning. After that, the pattern shifts to clean mornings and choppy afternoons for the rest of the outlook. Monday the 10th and Tuesday the 11th both have glassy mornings with 3ft and 3ft SSW swell, respectively.
Wednesday the 12th of August has a 2ft swell but the period jumps back to 18 seconds, and it’s glassy. The energy is moderate (388). Thursday the 13th and Friday the 14th both have clean, glassy starts with 3ft SSW swell at 15-17 seconds.
So, the one to circle on your calendar is Friday the 7th of August. That run from the 7th through the 9th offers the best combination of size, period, and glassy conditions. The river mouth should be handling that long-period swell beautifully. Just be aware that crowds are possible here, but with conditions this good, it’s worth 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.
