The Lowdown
G'day, I’m Rusty. Let’s have a look at what’s coming up for Bawa, a reef and point setup at an exposed SW-facing spot. It’s a very consistent break that handles a good range of swells, and it’s an advanced wave—so this isn’t beginner territory.
Right now we’ve got a gap at the start with no standout surf, but things fire up from Wednesday morning the 26th. That first session looks pretty magical: clear skies, glassy as a mirror—zero wind, just clean lines. Swell is 5ft from the SSW with a 13-second period, and the combined energy is moderate (919). It’s not huge, but with that offshore wind direction (NW) and the glassy surface, expect very good conditions for the experienced crew. It’s a proper start.
Thursday the 27th has a similar size (4ft SSW) but the wind goes cross-on and the swell period jumps to 19 seconds, which is a very long-period groundswell. That energy is strong (1775) but the cross-on breeze and the long period can make a reef-and-point like this a bit tricky—it might wall up and stand up, not straighten out like a beachie. Still, it’s punchy. Friday the 28th sees the swell building to 7ft (SSW, 16 seconds), but the wind is onshore by the afternoon, so early looks best. The combined energy is strong (2162) but the onshore wind kills the quality for paddle surfing—kite surfers would be eyeing it though.
The first real standout after the midweek flurry is Saturday morning the 29th. It’s clean again—glassy, 5ft SSW, with a 14-second period and moderate energy (1021). The wind is light easterly, glassing it up. It’s not massive, but for a point break with offshore-friendly direction, this is the pick of the first week. Crowds are possible here (sometimes), so get in early.
Sunday the 30th is smaller (3ft) but with that super long 21-second period swell—energy is moderate (1017) and the glassy morning will give you clean, long-lined waves. The long period means the sets will be spread out, so paddling out is easier, but it might be a bit straight for this spot. Still a good session for the patient.
We hit a bit of a lull through the middle of the week—Monday and Tuesday (31st and 1st) have bigger swell (up to 7ft) but the wind is cross-on or onshore, and the energy is high (2822 on Tuesday morning) but the quality is marginal. Worth a look if you’re desperate, but it’s not clean.
Wednesday morning the 2nd of September is another standout. Glassy conditions, 6ft SSW swell with a 16-second period, and strong energy (1882). Excellent surf for experienced surfers. This is the kind of morning you set the alarm for. The swell direction matches the optimum (SW), the break is exposed, and the wind is off the land. It’s a gem.
Thursday the 3rd eases to 5ft with a 15-second period—still glassy in the morning, good energy (1031), clean but smaller. Friday the 4th drops further to 4ft but stays glassy with a 13-second period (649 energy). Good for a cruisy session.
Saturday the 5th is tiny (3ft and 2ft) but the afternoon session surprises: 2ft with a 16-second SSW groundswell, glassy, and combined energy (559). It’s small but the period gives it some push. A longboarder’s dream.
Sunday the 6th sees 4ft SSW, 15 seconds, glassy morning (828 energy)—another tidy little session. Monday the 7th drops to 3ft, glassy, 14 seconds (486 energy). Not a standout but pleasant.
The final standout in the window is Thursday morning the 10th of September. Swell jumps to 6ft from the SSW with an 18-second period, and it’s glassy—easterly breeze 5 km/h. Combined energy is strong (2546). This is the biggest, cleanest, most powerful groundswell in the second week. For a reef-and-point that loves SW swell, this is your last hurrah. It’s expert territory at this size, but if you’re up for it, it’s a ripper.
Overall, Bawa is a consistent, quality spot with a few clear winners: Saturday 29th morning and Wednesday 2nd September morning, and that late-season Thursday 10th September. Water temp is about average for the time of year.

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.
