The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Alright, the outlook for La Barra is actually pretty solid for morning sessions, especially in the first week. The water temp is sitting around 87°, which is about a degree and a half warmer than normal for this time of year – feels like a warm bath, so you can go with a spring suit or just boardshorts.
We kick off Sunday morning, September 6th, with a clean 4ft SSW groundswell, period hanging around 15 seconds. The wind is dead glass, ENE 0 mph. That’s a proper long-period groundswell, so at La Barra, a river/jetty setup, it should handle the length well. The combined energy is moderate at 680. This is a standout morning – clean, lined up, and very good surf. The crowds are only sometimes a problem, so you might get a few out, but it’s worth it.
Sunday afternoon turns to rubbish with a 9 mph cross-on wind blowing it out. Give it a miss.
Monday morning, September 7th, is back to glassy conditions with a 3ft SSW swell, still a solid 14-second period. Energy is moderate at 504. Another very good morning session. The afternoons are all choppy and cross-on, a pattern that sticks for the whole forecast.
Tuesday morning, September 8th, is a touch smaller at 3ft, but glassy and clean. Very surfable.
Wednesday morning, September 9th, is similar – 3ft, glassy, with a long 16-second period. The energy is moderate at 463. Good conditions for a longer board.
Now, Thursday morning, September 10th, is a real highlight. The swell bumps up to 4ft from the SSW, period stretching to 17 seconds, and the energy is strong at 827. Wind is glass, and it’s clear skies. This is the best session of the whole outlook – a proper long period groundswell with clean, glassy conditions. If you can only paddle out once, make it this one.
After that, the mornings stay solid. Friday the 11th and Saturday the 12th both offer clean, glassy starts with 3ft to 3ft SSW swell. Energy drops a bit through the weekend, but still good.
There’s a bit of a lull around Sunday the 13th, with the swell dropping to 2ft and energy falling to 191. Still surfable, but nothing special.
The second week sees a bit of a revival. Monday the 14th morning is small, but Tuesday the 15th morning brings a clean 3ft groundswell with a very long 18-second period and offshores. Energy is strong at 533. Worth a look.
Wednesday the 16th morning is another glassy standout with 4ft, 16-second SSW swell and energy at 711. Very good again.
The rest of the week and into the next weekend holds clean, glassy mornings with swell ranging from 2ft to 3ft, some with very long periods over 18 seconds. The energy stays moderate, and the winds are light. The afternoons all blow out, so stick to the dawn patrol.
Best on offer: Thursday September 10th morning, and Wednesday September 16th morning. Both are glassy, chest-to-head-high groundswell with a lot of energy. Don’t sleep on them.
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.
