The Lowdown

Right then, let’s have a look at what’s on the cards for the next couple of weeks here.

Alright, the overall pattern is that we’ve got a consistent run of small to moderate SSW groundswell on the way, but the wind is going to be the real story. Most afternoons are cooked by a strong cross-onshore, so the early mornings are where you’ll find the clean windows. The water temp here is sitting at 87°F, which is a touch warmer than normal for this time of year, so you won’t need a thick suit.

The first few days are a bit slow to get going. Sunday the 13th has a tiny 2ft SSW swell with a cross-on wind, so it’s poor out there. Monday morning the 14th is glassy and clean with 2ft swell, but it’s very ordinary, just something to get wet on. The real standout starts on Tuesday the 15th. That morning is glassy with 2ft SSW swell and the energy is moderate (466). It’s small but clean and fun for a log or a fish. The best of the early run is Wednesday morning the 16th: glassy, 4ft SSW swell with a 16-second period – that’s proper groundswell energy (731), which at a river mouth like La Barra is going to set up nicely for the more experienced paddlers. That morning is the pick of the first week.

The Saturday morning the 19th and Sunday morning the 20th are worth a look too. Saturday has 2ft SSW, but it’s clean with a cross-off wind, and the swell period jumps to 18 seconds. Sunday the 20th is a serious shout: 3ft SSW swell with a 19-second period, clean cross-off wind, and a very strong energy reading (741). That’s a long-period groundswell, so the sets will be fat and waiting, but the wave shape at a river mouth should be good. Get on it early before the afternoon chop.

Into the second week, the consistency drops off a bit but there are still some clean windows. Tuesday morning the 22nd is glassy with 3ft SSW and moderate energy (475). Wednesday morning the 23rd is glassy with 3ft SSW. Friday morning the 25th has 3ft SW with a glassy start. The wind on the 26th and 27th is too strong and onshore to bother with. The swell direction shifts a bit more SW by the end of the run, so the optimum angle holds.

The best overall is Wednesday morning the 16th: glassy, 4ft, 16-second SSW groundswell, strong energy (731) – this is the one to circle. Sunday morning the 20th is a very close second: 3ft, 19-second period, clean cross-off, and a huge energy reading (741). Both are small by size but the quality and cleanliness will make them punch well above their weight.

La Barra can get a crowd sometimes, but on these early morning windows you’ll have a better chance of getting a few to yourself. The river mouth setup likes that SSW direction, so the banks should be working.

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.
