The Lowdown

Alright, Rusty here. Let’s have a look at the next few weeks for La Barra.

Right off the bat, the first few days are a write-off. We’ve got a little bump of south swell on Friday the 11th, but it’s tiny – only 1 foot – and the wind is all wrong, blowing onshore. It’s just not worth paddling out for. The water is sitting at 55°, which feels a touch warmer than usual for this time of year, but that’s small comfort when the surf is this flat and messy. Saturday the 12th actually sees the swell jump up to over 7 feet in the afternoon, with a combined energy of 520 (moderate wave energy), but the wind is straight onshore from the SSE, blowing 18-22 mph. It’s a choppy, blown-out mess, only for the most dedicated or the kite crew.

The pattern holds through Sunday the 13th and into Monday morning the 14th. The wind finally eases back Monday, swinging to a clean cross-offshore from the north. The swell drops to a modest 2 feet from the SSE, with a period of 10 seconds, and the combined energy is 144. The conditions are clean, but it’s very ordinary surf. It’s the first window that’s actually surfable, but you’ll be working for small, weak waves.

Tuesday the 15th is another no-go, with a fresh cross-offshore wind but almost no swell in the morning, and then the wind switches and the swell jumps to a short-period 5 feet from the SW in the afternoon, which is just lumpy cross-shore chop. The real hope shows up later in the week. Thursday the 17th is the standout in this entire forecast. The swell is a solid 4 feet from the SSE, with a nice 11-second period, giving it some push. The combined energy is 391 (moderate wave energy). But the best part? The wind is a clean cross-offshore from the NNE, blowing at 12 mph. That means clean, lined-up waves. This is the day to be at La Barra. It’s a point and river break, so it handles this south swell well, and the longer period will give you good shape. Crowds are *sometimes* a thing here, so you might have company, but the quality should be worth it.

After that, the forecast goes pretty quiet again. Friday the 18th through to the end of the period has small, weak swells, mostly under 3 feet, and the wind is rarely in our favor. There’s a brief pulse of 6 feet on Saturday the 26th from the south, but the wind is cross-onshore and choppy again. That’s a full week away and not looking promising. So, if you want a wave in the next two and a half weeks, your best bet is to point the car at La Barra for Thursday the 17th. The rest is mostly a waiting game.

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.
