The Lowdown
G’day, Rusty here. We’ve got a solid run of surf lining up at La Barra over the next couple of weeks, so grab ya board and let’s get into it.
First up, the water temp is sittin’ at a warm 87°, which is about 2° warmer than average for this time of year – nothin’ freaky, just a nice little bonus for a September paddle.
The real standout of the whole forecast is Wednesday morning, the 2nd of September. We’re lookin’ at a clean 2ft SSW groundswell with a long 17-second period, and the wind is dead glassy out of the east at just 3 mph. The combined swell energy is pumpin’ at a solid moderate 537, and that long period groundswell is gonna wrap nicely into the river mouth setup here. Expect very good surf – this is the pick of the bunch.
Don’t bother with the afternoons early on – that cross-onshore wind kicks in and messes things up. Thursday the 3rd is a write-off with messy cross-onshore wind and small swell, but Friday the 4th morning is another beauty: glassy conditions again, 4ft of SSW groundswell at 17 seconds, and the energy jumps to 1069 – moderate but with some punch. Saturday morning the 5th is just as good: 5ft SSW groundswell, glassy, with energy at 1222. That’s gonna be a ripper for experienced surfers.
Sunday the 6th morning holds clean 4ft SSW groundswell, and Monday the 7th morning drops to 3ft but still glassy – good for a fun session. Tuesday the 8th morning is dead calm with 3ft, and Wednesday the 9th morning is glassy again with 3ft. There’s a bit of a lull in size mid-week, but the conditions stay clean in the mornings.
From Thursday the 10th morning onward, we’re back into a pattern of glassy mornings with SSW groundswell around 3ft to 4ft, and the energy sits between 400 and 700 – moderate but consistent. Note that the weekend of the 12th and 13th September has clean conditions again, but afternoons are always a write-off with that cross-onshore wind.
Now, if you’re lookin’ further out, the morning of Thursday the 17th September has a tiny 2ft swell but with a massive 23-second period – that’s very long-period groundswell. The energy is 609, so it’s got some grunt, but that kind of period will make it better suited to the river mouth or a point break than a beach. Glassy as glass. It’s a promising long-range call, but don’t lock it in yet.
All in all, the mornings are where it’s at. Wednesday the 2nd and Saturday the 5th are the two absolute standouts – get out there early and you’ll be rewarded.
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.
