The Lowdown
G’day, Rusty here. We’ve got a solid run of surf ahead at La Barra, though you’ll need to pick your moments. The pattern starts with clean, glassy mornings and a decent long-period SSW groundswell that fades mid-week before a bigger, punchier swell moves in for the final days. Let’s break it down.
The first real action kicks off Friday morning, 11th September. La Barra is showing a 3ft SSW swell with a long 16-second period, and the wind is glassy from the west. It’s dead clean, the water’s 87° and a touch warmer than usual for this time of year. Combined wave energy is moderate at 560, and the offshore direction aligns perfectly with the SSW optimum. This is the standout of the first week – smooth, lined-up waves rolling into the river mouth. Classic.
Friday afternoon the wind swings southwest at 12 mph, going cross-on, and the surf drops to 3ft with a 15-second period. It gets choppy and messy. Saturday morning, the 12th, glass again with a lighter 3ft SSW swell at 14 seconds and energy at 338. Still clean, but smaller. Saturday afternoon the cross-on wind returns – better to wait for the morning.
Sunday the 13th is small and wonky with cross-on wind, not worth paddling out. Monday the 14th brings another glassy morning but only 1ft of long-period 19-second SSW groundswell – too weak to get excited about. Tuesday morning the 15th is glassy again with 3ft at 18 seconds and energy up to 523. Clean, but again, small. Wednesday morning the 16th is the real highlight: 4ft SSW at 16 seconds, dead calm, glassy as a mirror, energy at 771 – this is your best bet mid-week. Waves will be clean, lined up, with good shape for intermediates.
Thursday the 17th and Friday the 18th follow the same morning glass routine with 3ft to 3ft SSW, but the afternoons are blown out. Saturday the 19th morning sees a cross-off breeze from the northwest at 6 mph, keeping things clean with 2ft at 18 seconds, energy at 406 – nothing special but rideable.
Now for the second week. Sunday the 20th morning looks promising with offshores and 3ft of 19-second SSW groundswell, energy at 711. Clean, but that long period might make it break a bit straight at the river mouth. Monday the 21st morning is offshore too, 3ft at 18 seconds, energy 579. It’s a good run of mornings.
Tuesday the 22nd is a write-off – onshore winds and poor surf. But Wednesday the 23rd things change: a new 6ft SE swell comes in, 11-second period, energy jumps to 1032, but wind is cross-on. It’s marginal, a bit messy. Thursday the 24th gets bigger – 10ft SE at 10 seconds by morning, energy a whopping 1961. This is serious, but the forecast says it’s too big for La Barra – experts only if you’re brave, and it’s a beach setup with short period. Could be more of a kite session. Friday the 25th morning cleans up with a cross-off breeze and 7ft SSW swell at 9 seconds, energy 844 – solid, but the shorter period means chunky, close-outy waves.
Saturday the 26th morning returns to glassy conditions, 4ft SW at 9 seconds, energy 362 – a pleasant end to the run.
Overall, the standout is Friday 11th September morning – that glassy 3ft groundswell with 16-second period is primo. The Wednesday 16th morning is also a beauty. Later in the run, Sunday 20th and Monday 21st mornings offer clean groundswell, but it’s less certain this far out.
Crowds are listed as sometimes at La Barra, so you might have company on the good mornings.

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.
