The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipeline for La Barra.
We’ve got a solid stretch of surf ahead. This is a river/jetty set-up, exposed to the SSW swell, and the optimum direction matches perfectly. The water temp is about what you'd expect for this time of year, nothing freaky there. The opening days look the cleanest, but there are a few gems scattered through the whole run.
Thursday the 10th is your standout. Morning is gonna be pure magic – we’re talking a 4ft SSW groundswell with a very long 17-second period. The combined energy is solid (830), and with glassy, zero wind conditions, La Barra is going to be clean, lined-up, and offering some proper long, pushy waves. This isn’t a beginner wave at this size and period, but for the experienced crew, it’s the best on offer. Expect a few others out there with the same idea.
Friday the 11th morning is another cracker. A touch smaller at 4ft from the SSW, still a long 16-second period, and again, glassy calm winds. Energy is still strong (648). It won't have quite the same punch as Thursday, but it will be beautiful.
The afternoons through the first week turn into a write-off with onshore winds, so stick to the mornings. Saturday the 12th and Sunday the 13th offer smaller, cleaner waves (3ft and 2ft) with glassy conditions – good for a longer board or a learner on a fun day.
Looking ahead to the second week, there are more promising mornings. Tuesday the 15th brings back a 3ft, 18-second groundswell with glassy wind and strong energy (545). Thursday the 17th is also a solid call with a 3ft, 14-second swell and calm wind (580). Even Sunday the 20th looks tempting with a 3ft, 19-period groundswell and glassy conditions (663), though that's a bit further out so keep an eye on it.
Later in the month, from the 21st onwards, conditions get a bit messy with storms and onshore winds. There’s still some small, cleanish windows early morning on the 24th and 25th, but the swell drops and the quality fades.
Bottom line: the first 10 days are full of quality morning windows. Don’t sleep on Thursday the 10th.
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.
