The Lowdown
G’day, Rusty here. We’ve got a cracking little run shaping up at Bawa, so let’s get straight into it.
The surf kicks off this Saturday afternoon, August 8th, with a solid 8ft SSW groundswell pumping in. The combined energy is strong at 2749, so there’s plenty of grunt behind it. This is a reef and point set-up, and with that 16-second period, the waves will have serious shape and push – perfect for the experienced crew. The wind is a light, cross-off breeze from the WNW at 6 mph, leaving the face clean. Water temp is sitting at 86°, which is about normal for this time of year. Crowds can pop up here sometimes, so keep that in mind.
Sunday August 9th keeps the goodness coming. Morning brings a risk of thunderstorms but glassy conditions with an ESE breeze at 3 mph. The swell drops a fraction to 7ft, still SSW and 15 seconds – excellent power (2103). The afternoon cleans right up with clear skies and a glassy S wind at 3 mph. Same 7ft, 16-second swell, energy still at 2083. This is some of the cleanest surf you’ll see.
Monday August 10th starts to fade a little. Morning has a 6ft SSW swell at 14 seconds, but the wind swings SE at 6 mph, putting a light cross-onshore bump on it. Energy is still moderate at 1608, but the quality drops. Afternoon is similar, with the wind turning onshore from the SSW.
The real standout is Tuesday August 11th morning. Despite a risk of thunderstorms, the wind is glassy from the SE at 3 mph. The swell is 7ft from the south, but the period jumps to 18 seconds – that’s proper groundswell. Combined energy is 3397, the highest of the whole run. This is gonna be long, clean lines, especially for the point. Excellent for advanced surfers.
Wednesday August 12th morning offers another glassy window with an ENE breeze at 3 mph. The 7ft S swell at 17 seconds keeps the quality high (2370). From here, the swell slowly backs off through the week but remains in the 5ft to 6ft range for most mornings, often with glassy or light winds. Thursday 13th and Friday 14th August mornings both have glassy conditions and solid S swells around 5ft to 6ft, with periods holding strong at 15–17 seconds. Good energy, clean faces.
Saturday August 15th is more marginal with onshore winds and shorter period swell, so a bit of a rest day.
Sunday August 16th morning brings the swell down to 5ft from the south, 13 seconds, but with glassy SW winds – expect very good conditions, just smaller. Energy drops to 978.
Into the second week, Monday August 17th is small at 3ft SW, 14 seconds, but clean with a light cross-off breeze from the NNE. Worth a look if you’re after a cruisy session.
Tuesday August 18th sees a new pulse of 6ft SSW swell at 17 seconds, but the wind turns cross-onshore from the SE at 9 mph, making it choppy. Not the best.
Wednesday August 19th starts to get chunky again – 8ft SSW at 18 seconds, energy at 3929. The wind is light cross-shore, but any size over 8ft is for the experts only. This is a big, powerful groundswell, so only the experienced locals should paddle out.
Thursday August 20th holds that 8ft SSW, with similar energy levels (3924). Winds stay light cross-shore in the morning, turning cross-onshore in the arvo. Again, expert territory.
Friday August 21st morning has a 7ft SSW swell at 16 seconds, but the wind is onshore from the SSE. The size drops off a bit over the weekend, with Saturday August 22nd seeing 7ft and then Sunday August 23rd morning pulling a beauty – 5ft SSW at 14 seconds, completely glassy with no wind. Energy is 1066, and the forecast says excellent conditions for experienced surfers. A sweet end to the outlook.
Overall, the best bets are Tuesday August 11th morning for that long-period south swell, and Sunday the 9th or Wednesday the 12th August mornings for clean, powerful waves. The bigger 8ft-plus days are only for the hardcore.
Stay safe, keep your wits about you, and I’ll see you in the water.

Information about the Bawa Surf forecast
The above surf forecast table for Bawa provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bawa can be found by selecting the local surf guide option on the grey menu. Our Bawa 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 (Bawa) 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 Bawa 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.
