The Lowdown

Alright, Rusty here. Let’s look at what’s on offer for La Barra.

To be straight with you, the next 16 days look pretty grim. We’ve got a long stretch of poor conditions with hardly any windows worth paddling out for. The first week is mostly a write-off with strong cross and cross-onshore winds, messy chop, and weak, short-period swell. The water temp is about average for this time of year, nothin’ special.

The first real chance, and honestly the only time I’d get excited, is early on Thursday, the 10th of September. It’s a morning glass-off at La Barra (point/river). The wind goes glassy, dead calm, and the swell is a tiny 3 ft from the east, with a period of 9 seconds. The combined energy is weak (90), but it’s the only time the stars line up for a clean, workable wave. The optimum swell direction is from the south, so this east swell isn’t ideal, but when it’s glassy and the break is a point/river setup, you can still find a few fun ones. The crowd can be an issue here sometimes, but on a day like this, with such small surf, it might be quiet enough.

Later, on Saturday the 12th of September, there’s a bump in size. The swell jumps to 3 ft from the south, with a period of 13 seconds – that’s a decent groundswell. The combined energy is moderate (476). But the wind is a light cross-onshore, which will mess up the face. The report calls it marginal, and with that wind direction, it’s not going to be clean. For a point break, that long period is good for shape, but the wind is the letdown.

The rest of the period is a bust. There are big gaps of days with nothing worth paddling for. The second week is just more of the same: strong winds, onshore slop, and tiny waves. Honestly, it’s a stretch of “poor surf conditions” for days on end. Nothin’ else even comes close to a proper session.

If you’re desperate, get that Thursday morning glass-off. Otherwise, leave the board in the car and wait for the next forecast.

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.
