The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for La Barra over the next couple weeks.

We’ve got a nice run of clean, glassy mornings comin’ up, especially early on. The first real standout is this Saturday the 12th morning. It’s small, only 3ft of SSW swell, but with glassy conditions and light offshore wind from the west, it’s gonna be super clean. The combined swell energy is sittin’ in the moderate range (329), and with a 14-second period, there's some decent grunt behind it. La Barra (river/jetty) handles that direction well, so grab a log and enjoy the smooth faces before the afternoon cross-onshore kills it.

Keep your eye on Tuesday the 15th morning. That’s a beauty. 3ft again, but the period jumps to 18 seconds – proper groundswell. Glassy as hell with light northerly wind, and the energy is starting to build (521). That long period means the wave shapes should be real nice, especially pushin’ in from that optimum SSW direction. It’ll be clean, lined up, and a joy to paddle out at.

Then there’s Wednesday the 16th morning – that’s the pick of the first week for me. Swell bumps up to 4ft, still from the SSW, period at 16 seconds, and the combined energy jumps to a solid moderate-strong 763. It’s dead glassy with zero wind. This is as good as it gets for a river mouth setup – clean, pushy, and not too big. Watch for a few extra bodies in the water though – crowds are “sometimes” at La Barra, so it might get a bit busy on such a gem.

Later in the week, Sunday the 20th morning is also worth an early alarm. 3ft SSW swell at 19 seconds, glassy again, with a strong energy reading of 639. The long period here will make the waves stand up nicely on the bank.

Now, if you’re lookin’ further out to Saturday the 26th morning, there’s another chance. The swell drops a bit to 4ft from the SW with a shorter 9-second period, and the energy is moderate (490). It’s glassy though, so still worth a paddle if you’re around. But remember, that’s over a week away, so keep it on the radar but don’t lock your plans yet.

What about the wind? Mornings are your friend. Almost every afternoon turns into a choppy, cross-onshore mess, especially from the SW. The only real exception is the Saturday the 27th morning – clear skies, light offshore wind from the NW, clean conditions, and a nice 2ft SSW groundswell with 18 seconds and strong energy (693). That’s a solid second-week bonus, but it’s a long-range call, so treat it as promising but not set in stone.

There’s one gnarly day comin’ – Wednesday the 23rd. The swell jumps to 7ft from the SSE, but with a short 8-second period and strong onshore wind, it’s gonna be a messy, blown-out beast. The energy is huge (1118), but that’s more of a kite surfer’s day than a surfer’s. Wave quality is poor, and the wind kills it. Skip it.

Overall, the first week from Saturday the 12th through to Sunday the 20th has plenty of clean morning windows on offer. The standout mornings are Tuesday the 15th, Wednesday the 16th, and Sunday the 20th – those are the ones to aim for. After that, Saturday the 26th and Sunday the 27th give you a little second-week hope, but the pattern gets a bit more unsettled with shorter-period swell and more wind. Stay sharp and check the morning glass.

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.
