The Lowdown
G’day, Rusty here. Let’s break down what’s coming for La Barra.
The first few days are small but clean, with a real standout brewing for late next week. The river mouth will be the place to be when the wind plays nice. The best window is Saturday 25 July morning—that’s the one to remember.
Friday morning (17 July) is looking good. La Barra is a river/jetty break, exposed to the SSW swell, and it’s getting a 3ft groundswell at 14 seconds from the SSW. That’s a long-period swell, so you’ll get clean lines and long waits between sets. The wind is glassy from the north at 3 mph, and the water temp is about average for the season. The combined swell energy is 424—moderate. Crowds can show up sometimes, but this is a solid morning for intermediate surfers.
Saturday morning (18 July) is similar—3ft at 13 seconds, glassy from the southeast at 3 mph. Sunday morning (19 July) is dead calm, zero wind, with 3ft at 12 seconds. Perfect for a relaxed session.
Monday morning (20 July) has a light offshore from the northwest at 3 mph, with 3ft at 16 seconds. The combined energy is 476—still decent. Tuesday morning (21 July) is glassy again, 3ft at 15 seconds.
The swell drops from Wednesday (22 July) to Thursday (23 July) mornings—down to 2ft and 2ft, with energy dropping to 233 and 122. Surfable but very ordinary.
Then Friday morning (24 July) we see a period jump—3ft at 24 seconds from the SSW. The combined energy is 821—strong. The wind is light cross-off from the northwest at 6 mph, keeping it clean. This is a standout for the morning.
The best of the lot is Saturday morning (25 July). Swell hits 3ft at 21 seconds from the SSW, and the combined energy is a massive 1255—very strong. The wind is glassy from the northwest at 3 mph. This is excellent for experienced surfers. The swell direction matches the optimum SSW direction perfectly. This is the peak.
Sunday morning (26 July) is still strong—4ft at 19 seconds, 996 energy, glassy from the WNW. Monday morning (27 July) gets bigger—5ft at 18 seconds, 1487 energy, glassy again. This is for experienced surfers only, as the swell is over 5ft. Tuesday morning (28 July) is 5ft but the wind turns cross-onshore, making it marginal.
From Wednesday (29 July) it gets messy, but Thursday afternoon (30 July) brings a turnaround—offshore wind from the northwest at 12 mph, with 3ft at 14 seconds from the SSW. That’s clean and solid.
The last few mornings (31 July to 1 August) are small and clean—3ft to 2ft, glassy or light winds. A mellow finish.
The standout is Saturday 25 July morning—glass, solid groundswell, and strong energy. Don’t miss it.
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.
